-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),

-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)

-# So we provide this file, which has a silly filename so it's always
-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.

-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.

-.TH CJPEG 1 "26 July 2015"
-.SH NAME
-cjpeg \- compress an image file to a JPEG file
-.SH SYNOPSIS
-.B cjpeg
-[
-.I options
-]
-[
-.I filename
-]
-.LP
-.SH DESCRIPTION
-.LP
-.B cjpeg
-compresses the named image file, or the standard input if no file is
-named, and produces a JPEG/JFIF file on the standard output.
-The currently supported input file formats are: PPM (PBMPLUS color
-format), PGM (PBMPLUS grayscale format), BMP, Targa, and RLE (Utah Raster
-Toolkit format). (RLE is supported only if the URT library is available.)
-.SH OPTIONS
-All switch names may be abbreviated; for example,
-.B \-grayscale
-may be written
-.B \-gray
-or
-.BR \-gr .
-Most of the "basic" switches can be abbreviated to as little as one letter.
-Upper and lower case are equivalent (thus
-.B \-BMP
-is the same as
-.BR \-bmp ).
-British spellings are also accepted (e.g.,
-.BR \-greyscale ),
-though for brevity these are not mentioned below.
-.PP
-The basic switches are:
-.TP
-.BI \-quality " N[,...]"
-Scale quantization tables to adjust image quality. Quality is 0 (worst) to
-100 (best); default is 75. (See below for more info.)
-.TP
-.B \-grayscale
-Create monochrome JPEG file from color input. Be sure to use this switch when
-compressing a grayscale BMP file, because
-.B cjpeg
-isn't bright enough to notice whether a BMP file uses only shades of gray.
-By saying
-.BR \-grayscale ,
-you'll get a smaller JPEG file that takes less time to process.
-.TP
-.B \-rgb
-Create RGB JPEG file.
-Using this switch suppresses the conversion from RGB
-colorspace input to the default YCbCr JPEG colorspace.
-You can use this switch in combination with the
-.BI \-block " N"
-switch (see below) for lossless JPEG coding.
-See also the
-.B \-rgb1
-switch below.
-.TP
-.B \-optimize
-Perform optimization of entropy encoding parameters. Without this, default
-encoding parameters are used.
-.B \-optimize
-usually makes the JPEG file a little smaller, but
-.B cjpeg
-runs somewhat slower and needs much more memory. Image quality and speed of
-decompression are unaffected by
-.BR \-optimize .
-.TP
-.B \-progressive
-Create progressive JPEG file (see below).
-.TP
-.BI \-scale " M/N"
-Scale the output image by a factor M/N. Currently supported scale factors are
-M/N with all N from 1 to 16, where M is the destination DCT size, which is 8
-by default (see
-.BI \-block " N"
-switch below).
-.TP
-.B \-targa
-Input file is Targa format. Targa files that contain an "identification"
-field will not be automatically recognized by
-.BR cjpeg ;
-for such files you must specify
-.B \-targa
-to make
-.B cjpeg
-treat the input as Targa format.
-For most Targa files, you won't need this switch.
-.PP
-The
-.B \-quality
-switch lets you trade off compressed file size against quality of the
-reconstructed image: the higher the quality setting, the larger the JPEG file,
-and the closer the output image will be to the original input. Normally you
-want to use the lowest quality setting (smallest file) that decompresses into
-something visually indistinguishable from the original image. For this
-purpose the quality setting should be between 50 and 95; the default of 75 is
-often about right. If you see defects at
-.B \-quality
-75, then go up 5 or 10 counts at a time until you are happy with the output
-image. (The optimal setting will vary from one image to another.)
-.PP
-.B \-quality
-100 will generate a quantization table of all 1's, minimizing loss in the
-quantization step (but there is still information loss in subsampling, as well
-as roundoff error). This setting is mainly of interest for experimental
-purposes. Quality values above about 95 are
-.B not
-recommended for normal use; the compressed file size goes up dramatically for
-hardly any gain in output image quality.
-.PP
-In the other direction, quality values below 50 will produce very small files
-of low image quality. Settings around 5 to 10 might be useful in preparing an
-index of a large image library, for example. Try
-.B \-quality
-2 (or so) for some amusing Cubist effects. (Note: quality
-values below about 25 generate 2-byte quantization tables, which are
-considered optional in the JPEG standard.
-.B cjpeg
-emits a warning message when you give such a quality value, because some
-other JPEG programs may be unable to decode the resulting file. Use
-.B \-baseline
-if you need to ensure compatibility at low quality values.)
-.PP
-The
-.B \-quality
-option has been extended in IJG version 7 for support of separate quality
-settings for luminance and chrominance (or in general, for every provided
-quantization table slot). This feature is useful for high-quality
-applications which cannot accept the damage of color data by coarse
-subsampling settings. You can now easily reduce the color data amount more
-smoothly with finer control without separate subsampling. The resulting file
-is fully compliant with standard JPEG decoders.
-Note that the
-.B \-quality
-ratings refer to the quantization table slots, and that the last value is
-replicated if there are more q-table slots than parameters. The default
-q-table slots are 0 for luminance and 1 for chrominance with default tables as
-given in the JPEG standard. This is compatible with the old behaviour in case
-that only one parameter is given, which is then used for both luminance and
-chrominance (slots 0 and 1). More or custom quantization tables can be set
-with
-.B \-qtables
-and assigned to components with
-.B \-qslots
-parameter (see the "wizard" switches below).
-.B Caution:
-You must explicitly add
-.BI \-sample " 1x1"
-for efficient separate color
-quality selection, since the default value used by library is 2x2!
-.PP
-The
-.B \-progressive
-switch creates a "progressive JPEG" file. In this type of JPEG file, the data
-is stored in multiple scans of increasing quality. If the file is being
-transmitted over a slow communications link, the decoder can use the first
-scan to display a low-quality image very quickly, and can then improve the
-display with each subsequent scan. The final image is exactly equivalent to a
-standard JPEG file of the same quality setting, and the total file size is
-about the same --- often a little smaller.
-.PP
-Switches for advanced users:
-.TP
-.B \-arithmetic
-Use arithmetic coding.
-.B Caution:
-arithmetic coded JPEG is not yet widely implemented, so many decoders will
-be unable to view an arithmetic coded JPEG file at all.
-.TP
-.BI \-block " N"
-Set DCT block size. All N from 1 to 16 are possible.
-Default is 8 (baseline format).
-Larger values produce higher compression,
-smaller values produce higher quality
-(exact DCT stage possible with 1 or 2; with the default quality of 75 and
-default Luminance qtable the DCT+Quantization stage is lossless for N=1).
-.B Caution:
-An implementation of the JPEG SmartScale extension is required for this
-feature. SmartScale enabled JPEG is not yet widely implemented, so many
-decoders will be unable to view a SmartScale extended JPEG file at all.
-.TP
-.B \-rgb1
-Create RGB JPEG file with reversible color transform.
-Works like the
-.B \-rgb
-switch (see above) and inserts a simple reversible color transform
-into the processing which significantly improves the compression.
-Use this switch in combination with the
-.BI \-block " N"
-switch (see above) for lossless JPEG coding.
-.B Caution:
-A decoder with inverse color transform support is required for
-this feature. Reversible color transform support is not yet
-widely implemented, so many decoders will be unable to view
-a reversible color transformed JPEG file at all.
-.TP
-.B \-bgycc
-Create big gamut YCC JPEG file.
-In this type of encoding the color difference components are quantized
-further by a factor of 2 compared to the normal Cb/Cr values, thus creating
-space to allow larger color values with higher saturation than the normal
-gamut limits to be encoded. In order to compensate for the loss of color
-fidelity compared to a normal YCC encoded file, the color quantization
-tables can be adjusted accordingly. For example,
-.B cjpeg \-bgycc \-quality
-80,90 will give similar results as
-.B cjpeg \-quality
-80.
-.B Caution:
-For correct decompression a decoder with big gamut YCC support (JFIF
-version 2) is required. An old decoder may or may not display a big
-gamut YCC encoded JPEG file, depending on JFIF version check and
-corresponding warning/error configuration. In case of a granted
-decompression the old decoder will display the image with half
-saturated colors.
-.TP
-.B \-dct int
-Use integer DCT method (default).
-.TP
-.B \-dct fast
-Use fast integer DCT (less accurate).
-.TP
-.B \-dct float
-Use floating-point DCT method.
-The float method is very slightly more accurate than the int method, but is
-much slower unless your machine has very fast floating-point hardware. Also
-note that results of the floating-point method may vary slightly across
-machines, while the integer methods should give the same results everywhere.
-The fast integer method is much less accurate than the other two.
-.TP
-.B \-nosmooth
-Don't use high-quality downsampling.
-.TP
-.BI \-restart " N"
-Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is
-attached to the number.
-.B \-restart 0
-(the default) means no restart markers.
-.TP
-.BI \-smooth " N"
-Smooth the input image to eliminate dithering noise. N, ranging from 1 to
-100, indicates the strength of smoothing. 0 (the default) means no smoothing.
-.TP
-.BI \-maxmemory " N"
-Set limit for amount of memory to use in processing large images. Value is
-in thousands of bytes, or millions of bytes if "M" is attached to the
-number. For example,
-.B \-max 4m
-selects 4000000 bytes. If more space is needed, temporary files will be used.
-.TP
-.BI \-outfile " name"
-Send output image to the named file, not to standard output.
-.TP
-.B \-verbose
-Enable debug printout. More
-.BR \-v 's
-give more output. Also, version information is printed at startup.
-.TP
-.B \-debug
-Same as
-.BR \-verbose .
-.PP
-The
-.B \-restart
-option inserts extra markers that allow a JPEG decoder to resynchronize after
-a transmission error. Without restart markers, any damage to a compressed
-file will usually ruin the image from the point of the error to the end of the
-image; with restart markers, the damage is usually confined to the portion of
-the image up to the next restart marker. Of course, the restart markers
-occupy extra space. We recommend
-.B \-restart 1
-for images that will be transmitted across unreliable networks such as Usenet.
-.PP
-The
-.B \-smooth
-option filters the input to eliminate fine-scale noise. This is often useful
-when converting dithered images to JPEG: a moderate smoothing factor of 10 to
-50 gets rid of dithering patterns in the input file, resulting in a smaller
-JPEG file and a better-looking image. Too large a smoothing factor will
-visibly blur the image, however.
-.PP
-Switches for wizards:
-.TP
-.B \-baseline
-Force baseline-compatible quantization tables to be generated. This clamps
-quantization values to 8 bits even at low quality settings. (This switch is
-poorly named, since it does not ensure that the output is actually baseline
-JPEG. For example, you can use
-.B \-baseline
-and
-.B \-progressive
-together.)
-.TP
-.BI \-qtables " file"
-Use the quantization tables given in the specified text file.
-.TP
-.BI \-qslots " N[,...]"
-Select which quantization table to use for each color component.
-.TP
-.BI \-sample " HxV[,...]"
-Set JPEG sampling factors for each color component.
-.TP
-.BI \-scans " file"
-Use the scan script given in the specified text file.
-.PP
-The "wizard" switches are intended for experimentation with JPEG. If you
-don't know what you are doing, \fBdon't use them\fR. These switches are
-documented further in the file wizard.txt.
-.SH EXAMPLES
-.LP
-This example compresses the PPM file foo.ppm with a quality factor of
-60 and saves the output as foo.jpg:
-.IP
-.B cjpeg \-quality
-.I 60 foo.ppm
-.B >
-.I foo.jpg
-.SH HINTS
-Color GIF files are not the ideal input for JPEG; JPEG is really intended for
-compressing full-color (24-bit) images. In particular, don't try to convert
-cartoons, line drawings, and other images that have only a few distinct
-colors. GIF works great on these, JPEG does not. If you want to convert a
-GIF to JPEG, you should experiment with
-.BR cjpeg 's
-.B \-quality
-and
-.B \-smooth
-options to get a satisfactory conversion.
-.B \-smooth 10
-or so is often helpful.
-.PP
-Avoid running an image through a series of JPEG compression/decompression
-cycles. Image quality loss will accumulate; after ten or so cycles the image
-may be noticeably worse than it was after one cycle. It's best to use a
-lossless format while manipulating an image, then convert to JPEG format when
-you are ready to file the image away.
-.PP
-The
-.B \-optimize
-option to
-.B cjpeg
-is worth using when you are making a "final" version for posting or archiving.
-It's also a win when you are using low quality settings to make very small
-JPEG files; the percentage improvement is often a lot more than it is on
-larger files. (At present,
-.B \-optimize
-mode is always selected when generating progressive JPEG files.)
-.SH ENVIRONMENT
-.TP
-.B JPEGMEM
-If this environment variable is set, its value is the default memory limit.
-The value is specified as described for the
-.B \-maxmemory
-switch.
-.B JPEGMEM
-overrides the default value specified when the program was compiled, and
-itself is overridden by an explicit
-.BR \-maxmemory .

-Independent JPEG Group
-.SH BUGS
-GIF input files are no longer supported, to avoid the Unisys LZW patent
-(now expired).
-(Conversion of GIF files to JPEG is usually a bad idea anyway.)

-The
-.B \-targa
-switch is not a bug, it's a feature. (It would be a bug if the Targa format
-designers had not been clueless.)

- * This routine determines what format the input file is,

- * To determine which family of input formats the file belongs to,
- * we may look only at the first byte of the file, since C does not
- * guarantee that more than one character can be pushed back with ungetc.
- * Looking at additional bytes would require one of these approaches:
- * 1) assume we can fseek() the input file (fails for piped input);
- * 2) assume we can push back more than one character (works in

- * 3) provide our own buffering (breaks input readers that want to use

- * The most portable solution for file types that can't be identified by their

-IJG JPEG LIBRARY: CODING RULES
-
-Copyright (C) 1991-1996, Thomas G. Lane.
-This file is part of the Independent JPEG Group's software.
-For conditions of distribution and use, see the accompanying README file.
-
-
-Since numerous people will be contributing code and bug fixes, it's important
-to establish a common coding style. The goal of using similar coding styles
-is much more important than the details of just what that style is.
-
-In general we follow the recommendations of "Recommended C Style and Coding
-Standards" revision 6.1 (Cannon et al. as modified by Spencer, Keppel and
-Brader). This document is available in the IJG FTP archive (see
-jpeg/doc/cstyle.ms.tbl.Z, or cstyle.txt.Z for those without nroff/tbl).
-
-Block comments should be laid out thusly:
-
-/*
- * Block comments in this style.
- */
-
-We indent statements in K&R style, e.g.,
- if (test) {
- then-part;
- } else {
- else-part;
- }
-with two spaces per indentation level. (This indentation convention is
-handled automatically by GNU Emacs and many other text editors.)
-
-Multi-word names should be written in lower case with underscores, e.g.,
-multi_word_name (not multiWordName). Preprocessor symbols and enum constants
-are similar but upper case (MULTI_WORD_NAME). Names should be unique within
-the first fifteen characters. (On some older systems, global names must be
-unique within six characters. We accommodate this without cluttering the
-source code by using macros to substitute shorter names.)
-
-We use function prototypes everywhere; we rely on automatic source code
-transformation to feed prototype-less C compilers. Transformation is done
-by the simple and portable tool 'ansi2knr.c' (courtesy of Ghostscript).
-ansi2knr is not very bright, so it imposes a format requirement on function
-declarations: the function name MUST BEGIN IN COLUMN 1. Thus all functions
-should be written in the following style:
-
-LOCAL(int *)
-function_name (int a, char *b)
-{
- code...
-}
-
-Note that each function definition must begin with GLOBAL(type), LOCAL(type),
-or METHODDEF(type). These macros expand to "static type" or just "type" as
-appropriate. They provide a readable indication of the routine's usage and
-can readily be changed for special needs. (For instance, special linkage
-keywords can be inserted for use in Windows DLLs.)
-
-ansi2knr does not transform method declarations (function pointers in
-structs). We handle these with a macro JMETHOD, defined as
- #ifdef HAVE_PROTOTYPES
- #define JMETHOD(type,methodname,arglist) type (*methodname) arglist
- #else
- #define JMETHOD(type,methodname,arglist) type (*methodname) ()
- #endif
-which is used like this:
- struct function_pointers {
- JMETHOD(void, init_entropy_encoder, (int somearg, jparms *jp));
- JMETHOD(void, term_entropy_encoder, (void));
- };
-Note the set of parentheses surrounding the parameter list.
-
-A similar solution is used for forward and external function declarations
-(see the EXTERN and JPP macros).
-
-If the code is to work on non-ANSI compilers, we cannot rely on a prototype
-declaration to coerce actual parameters into the right types. Therefore, use
-explicit casts on actual parameters whenever the actual parameter type is not
-identical to the formal parameter. Beware of implicit conversions to "int".
-
-It seems there are some non-ANSI compilers in which the sizeof() operator
-is defined to return int, yet size_t is defined as long. Needless to say,
-this is brain-damaged. Always use the SIZEOF() macro in place of sizeof(),
-so that the result is guaranteed to be of type size_t.
-
-
-The JPEG library is intended to be used within larger programs. Furthermore,
-we want it to be reentrant so that it can be used by applications that process
-multiple images concurrently. The following rules support these requirements:
-
-1. Avoid direct use of file I/O, "malloc", error report printouts, etc;
-pass these through the common routines provided.
-
-2. Minimize global namespace pollution. Functions should be declared static
-wherever possible. (Note that our method-based calling conventions help this
-a lot: in many modules only the initialization function will ever need to be
-called directly, so only that function need be externally visible.) All
-global function names should begin with "jpeg_", and should have an
-abbreviated name (unique in the first six characters) substituted by macro
-when NEED_SHORT_EXTERNAL_NAMES is set.
-
-3. Don't use global variables; anything that must be used in another module
-should be in the common data structures.
-
-4. Don't use static variables except for read-only constant tables. Variables
-that should be private to a module can be placed into private structures (see
-the system architecture document, structure.txt).
-
-5. Source file names should begin with "j" for files that are part of the
-library proper; source files that are not part of the library, such as cjpeg.c
-and djpeg.c, do not begin with "j". Keep source file names to eight
-characters (plus ".c" or ".h", etc) to make life easy for MS-DOSers. Keep
-compression and decompression code in separate source files --- some
-applications may want only one half of the library.
-
-Note: these rules (particularly #4) are not followed religiously in the
-modules that are used in cjpeg/djpeg but are not part of the JPEG library
-proper. Those modules are not really intended to be used in other
-applications.

-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking ...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]

- --with-aix-soname=aix|svr4|both
- shared library versioning (aka "SONAME") variant to
- provide on AIX, [default=aix].
- --with-gnu-ld assume the C compiler uses GNU ld [default=no]
- --with-sysroot[=DIR] Search for dependent libraries within DIR (or the
- compiler's sysroot if not specified).
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L if you have libraries in a
- nonstandard directory
- LIBS libraries to pass to the linker, e.g. -l
- CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if
- you have headers in a nonstandard directory
- CPP C preprocessor
- LT_SYS_LIBRARY_PATH
- User-defined run-time library search path.
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

-.TH DJPEG 1 "26 July 2015"
-.SH NAME
-djpeg \- decompress a JPEG file to an image file
-.SH SYNOPSIS
-.B djpeg
-[
-.I options
-]
-[
-.I filename
-]
-.LP
-.SH DESCRIPTION
-.LP
-.B djpeg
-decompresses the named JPEG file, or the standard input if no file is named,
-and produces an image file on the standard output. PBMPLUS (PPM/PGM), BMP,
-GIF, Targa, or RLE (Utah Raster Toolkit) output format can be selected.
-(RLE is supported only if the URT library is available.)
-.SH OPTIONS
-All switch names may be abbreviated; for example,
-.B \-grayscale
-may be written
-.B \-gray
-or
-.BR \-gr .
-Most of the "basic" switches can be abbreviated to as little as one letter.
-Upper and lower case are equivalent (thus
-.B \-BMP
-is the same as
-.BR \-bmp ).
-British spellings are also accepted (e.g.,
-.BR \-greyscale ),
-though for brevity these are not mentioned below.
-.PP
-The basic switches are:
-.TP
-.BI \-colors " N"
-Reduce image to at most N colors. This reduces the number of colors used in
-the output image, so that it can be displayed on a colormapped display or
-stored in a colormapped file format. For example, if you have an 8-bit
-display, you'd need to reduce to 256 or fewer colors.
-.TP
-.BI \-quantize " N"
-Same as
-.BR \-colors .
-.B \-colors
-is the recommended name,
-.B \-quantize
-is provided only for backwards compatibility.
-.TP
-.B \-fast
-Select recommended processing options for fast, low quality output. (The
-default options are chosen for highest quality output.) Currently, this is
-equivalent to \fB\-dct fast \-nosmooth \-onepass \-dither ordered\fR.
-.TP
-.B \-grayscale
-Force grayscale output even if JPEG file is color.
-Useful for viewing on monochrome displays; also,
-.B djpeg
-runs noticeably faster in this mode.
-.TP
-.B \-rgb
-Force RGB output even if JPEG file is grayscale.
-This is provided to support applications that don't
-want to cope with grayscale as a separate case.
-.TP
-.BI \-scale " M/N"
-Scale the output image by a factor M/N. Currently supported scale factors are
-M/N with all M from 1 to 16, where N is the source DCT size, which is 8 for
-baseline JPEG. If the /N part is omitted, then M specifies the DCT scaled
-size to be applied on the given input. For baseline JPEG this is equivalent
-to M/8 scaling, since the source DCT size for baseline JPEG is 8.
-Scaling is handy if the image is larger than your screen; also,
-.B djpeg
-runs much faster when scaling down the output.
-.TP
-.B \-bmp
-Select BMP output format (Windows flavor). 8-bit colormapped format is
-emitted if
-.B \-colors
-or
-.B \-grayscale
-is specified, or if the JPEG file is grayscale; otherwise, 24-bit full-color
-format is emitted.
-.TP
-.B \-gif
-Select GIF output format. Since GIF does not support more than 256 colors,
-.B \-colors 256
-is assumed (unless you specify a smaller number of colors).
-.TP
-.B \-os2
-Select BMP output format (OS/2 1.x flavor). 8-bit colormapped format is
-emitted if
-.B \-colors
-or
-.B \-grayscale
-is specified, or if the JPEG file is grayscale; otherwise, 24-bit full-color
-format is emitted.
-.TP
-.B \-pnm
-Select PBMPLUS (PPM/PGM) output format (this is the default format).
-PGM is emitted if the JPEG file is grayscale or if
-.B \-grayscale
-is specified; otherwise PPM is emitted.
-.TP
-.B \-rle
-Select RLE output format. (Requires URT library.)
-.TP
-.B \-targa
-Select Targa output format. Grayscale format is emitted if the JPEG file is
-grayscale or if
-.B \-grayscale
-is specified; otherwise, colormapped format is emitted if
-.B \-colors
-is specified; otherwise, 24-bit full-color format is emitted.
-.PP
-Switches for advanced users:
-.TP
-.B \-dct int
-Use integer DCT method (default).
-.TP
-.B \-dct fast
-Use fast integer DCT (less accurate).
-.TP
-.B \-dct float
-Use floating-point DCT method.
-The float method is very slightly more accurate than the int method, but is
-much slower unless your machine has very fast floating-point hardware. Also
-note that results of the floating-point method may vary slightly across
-machines, while the integer methods should give the same results everywhere.
-The fast integer method is much less accurate than the other two.
-.TP
-.B \-dither fs
-Use Floyd-Steinberg dithering in color quantization.
-.TP
-.B \-dither ordered
-Use ordered dithering in color quantization.
-.TP
-.B \-dither none
-Do not use dithering in color quantization.
-By default, Floyd-Steinberg dithering is applied when quantizing colors; this
-is slow but usually produces the best results. Ordered dither is a compromise
-between speed and quality; no dithering is fast but usually looks awful. Note
-that these switches have no effect unless color quantization is being done.
-Ordered dither is only available in
-.B \-onepass
-mode.
-.TP
-.BI \-map " file"
-Quantize to the colors used in the specified image file. This is useful for
-producing multiple files with identical color maps, or for forcing a
-predefined set of colors to be used. The
-.I file
-must be a GIF or PPM file. This option overrides
-.B \-colors
-and
-.BR \-onepass .
-.TP
-.B \-nosmooth
-Don't use high-quality upsampling.
-.TP
-.B \-onepass
-Use one-pass instead of two-pass color quantization. The one-pass method is
-faster and needs less memory, but it produces a lower-quality image.
-.B \-onepass
-is ignored unless you also say
-.B \-colors
-.IR N .
-Also, the one-pass method is always used for grayscale output (the two-pass
-method is no improvement then).
-.TP
-.BI \-maxmemory " N"
-Set limit for amount of memory to use in processing large images. Value is
-in thousands of bytes, or millions of bytes if "M" is attached to the
-number. For example,
-.B \-max 4m
-selects 4000000 bytes. If more space is needed, temporary files will be used.
-.TP
-.BI \-outfile " name"
-Send output image to the named file, not to standard output.
-.TP
-.B \-verbose
-Enable debug printout. More
-.BR \-v 's
-give more output. Also, version information is printed at startup.
-.TP
-.B \-debug
-Same as
-.BR \-verbose .
-.SH EXAMPLES
-.LP
-This example decompresses the JPEG file foo.jpg, quantizes it to
-256 colors, and saves the output in 8-bit BMP format in foo.bmp:
-.IP
-.B djpeg \-colors 256 \-bmp
-.I foo.jpg
-.B >
-.I foo.bmp
-.SH HINTS
-To get a quick preview of an image, use the
-.B \-grayscale
-and/or
-.B \-scale
-switches.
-.B \-grayscale \-scale 1/8
-is the fastest case.
-.PP
-Several options are available that trade off image quality to gain speed.
-.B \-fast
-turns on the recommended settings.
-.PP
-.B \-dct fast
-and/or
-.B \-nosmooth
-gain speed at a small sacrifice in quality.
-When producing a color-quantized image,
-.B \-onepass \-dither ordered
-is fast but much lower quality than the default behavior.
-.B \-dither none
-may give acceptable results in two-pass mode, but is seldom tolerable in
-one-pass mode.
-.PP
-If you are fortunate enough to have very fast floating point hardware,
-\fB\-dct float\fR may be even faster than \fB\-dct fast\fR. But on most
-machines \fB\-dct float\fR is slower than \fB\-dct int\fR; in this case it is
-not worth using, because its theoretical accuracy advantage is too small to be
-significant in practice.
-.SH ENVIRONMENT
-.TP
-.B JPEGMEM
-If this environment variable is set, its value is the default memory limit.
-The value is specified as described for the
-.B \-maxmemory
-switch.
-.B JPEGMEM
-overrides the default value specified when the program was compiled, and
-itself is overridden by an explicit
-.BR \-maxmemory .

-.B djpeg
-produces uncompressed GIF files. These are larger than they should be, but
-are readable by standard GIF decoders.

- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains a command-line user interface for the JPEG decompressor.
- * It should work on any system with Unix- or MS-DOS-style command lines.
- *
- * Two different command line styles are permitted, depending on the
- * compile-time switch TWO_FILE_COMMANDLINE:
- * djpeg [options] inputfile outputfile
- * djpeg [options] [inputfile]
- * In the second style, output is always to standard output, which you'd
- * normally redirect to a file or pipe to some other program. Input is
- * either from a named file or from standard input (typically redirected).
- * The second style is convenient on Unix but is unhelpful on systems that
- * don't support pipes. Also, you MUST use the first style if your system
- * doesn't do binary I/O to stdin/stdout.
- * To simplify script writing, the "-outfile" switch is provided. The syntax
- * djpeg [options] -outfile outputfile inputfile
- * works regardless of which command line style is used.

- * files to be compatible with everyone else's. If you cannot readily read
- * your data in that order, you'll need an intermediate array to hold the

- *
- * Just to make this example a little different from the first one, we'll

- * ERROR HANDLING:

- * adjust the behavior without duplicating a lot of code, which you might
- * have to update with each future release.
- *
- * Our example here shows how to override the "error_exit" method so that
- * control is returned to the library's caller when a fatal error occurs,
- * rather than calling exit() as the standard error_exit method does.
- *
- * We use C's setjmp/longjmp facility to return control. This means that the

- * establish the return point. We want the replacement error_exit to do a
- * longjmp(). But we need to make the setjmp buffer accessible to the
- * error_exit routine. To do this, we make a private extension of the
- * standard JPEG error handler object. (If we were using C++, we'd say we
- * were making a subclass of the regular error handler.)
- *
- * Here's the extended error handler struct:

-IJG JPEG LIBRARY: FILE LIST
-
-Copyright (C) 1994-2013, Thomas G. Lane, Guido Vollbeding.
-This file is part of the Independent JPEG Group's software.
-For conditions of distribution and use, see the accompanying README file.
-
-
-Here is a road map to the files in the IJG JPEG distribution. The
-distribution includes the JPEG library proper, plus two application
-programs ("cjpeg" and "djpeg") which use the library to convert JPEG
-files to and from some other popular image formats. A third application
-"jpegtran" uses the library to do lossless conversion between different
-variants of JPEG. There are also two stand-alone applications,
-"rdjpgcom" and "wrjpgcom".
-
-
-THE JPEG LIBRARY
-================
-
-Include files:
-
-jpeglib.h JPEG library's exported data and function declarations.
-jconfig.h Configuration declarations. Note: this file is not present
- in the distribution; it is generated during installation.
-jmorecfg.h Additional configuration declarations; need not be changed
- for a standard installation.
-jerror.h Declares JPEG library's error and trace message codes.
-jinclude.h Central include file used by all IJG .c files to reference
- system include files.
-jpegint.h JPEG library's internal data structures.
-jdct.h Private declarations for forward & reverse DCT subsystems.
-jmemsys.h Private declarations for memory management subsystem.
-jversion.h Version information.

-Applications using the library should include jpeglib.h (which in turn
-includes jconfig.h and jmorecfg.h). Optionally, jerror.h may be included
-if the application needs to reference individual JPEG error codes. The
-other include files are intended for internal use and would not normally
-be included by an application program. (cjpeg/djpeg/etc do use jinclude.h,
-since its function is to improve portability of the whole IJG distribution.
-Most other applications will directly include the system include files they
-want, and hence won't need jinclude.h.)
-
-
-C source code files:
-
-These files contain most of the functions intended to be called directly by
-an application program:
-
-jcapimin.c Application program interface: core routines for compression.
-jcapistd.c Application program interface: standard compression.
-jdapimin.c Application program interface: core routines for decompression.
-jdapistd.c Application program interface: standard decompression.
-jcomapi.c Application program interface routines common to compression
- and decompression.
-jcparam.c Compression parameter setting helper routines.
-jctrans.c API and library routines for transcoding compression.
-jdtrans.c API and library routines for transcoding decompression.
-
-Compression side of the library:
-
-jcinit.c Initialization: determines which other modules to use.
-jcmaster.c Master control: setup and inter-pass sequencing logic.
-jcmainct.c Main buffer controller (preprocessor => JPEG compressor).
-jcprepct.c Preprocessor buffer controller.
-jccoefct.c Buffer controller for DCT coefficient buffer.
-jccolor.c Color space conversion.
-jcsample.c Downsampling.
-jcdctmgr.c DCT manager (DCT implementation selection & control).
-jfdctint.c Forward DCT using slow-but-accurate integer method.
-jfdctfst.c Forward DCT using faster, less accurate integer method.
-jfdctflt.c Forward DCT using floating-point arithmetic.
-jchuff.c Huffman entropy coding.
-jcarith.c Arithmetic entropy coding.
-jcmarker.c JPEG marker writing.
-jdatadst.c Data destination managers for memory and stdio output.
-
-Decompression side of the library:
-
-jdmaster.c Master control: determines which other modules to use.
-jdinput.c Input controller: controls input processing modules.
-jdmainct.c Main buffer controller (JPEG decompressor => postprocessor).
-jdcoefct.c Buffer controller for DCT coefficient buffer.
-jdpostct.c Postprocessor buffer controller.
-jdmarker.c JPEG marker reading.
-jdhuff.c Huffman entropy decoding.
-jdarith.c Arithmetic entropy decoding.
-jddctmgr.c IDCT manager (IDCT implementation selection & control).
-jidctint.c Inverse DCT using slow-but-accurate integer method.
-jidctfst.c Inverse DCT using faster, less accurate integer method.
-jidctflt.c Inverse DCT using floating-point arithmetic.
-jdsample.c Upsampling.
-jdcolor.c Color space conversion.
-jdmerge.c Merged upsampling/color conversion (faster, lower quality).
-jquant1.c One-pass color quantization using a fixed-spacing colormap.
-jquant2.c Two-pass color quantization using a custom-generated colormap.
- Also handles one-pass quantization to an externally given map.
-jdatasrc.c Data source managers for memory and stdio input.
-
-Support files for both compression and decompression:
-
-jaricom.c Tables for common use in arithmetic entropy encoding and
- decoding routines.
-jerror.c Standard error handling routines (application replaceable).
-jmemmgr.c System-independent (more or less) memory management code.
-jutils.c Miscellaneous utility routines.
-
-jmemmgr.c relies on a system-dependent memory management module. The IJG
-distribution includes the following implementations of the system-dependent
-module:
-
-jmemnobs.c "No backing store": assumes adequate virtual memory exists.
-jmemansi.c Makes temporary files with ANSI-standard routine tmpfile().
-jmemname.c Makes temporary files with program-generated file names.
-jmemdos.c Custom implementation for MS-DOS (16-bit environment only):
- can use extended and expanded memory as well as temp files.
-jmemmac.c Custom implementation for Apple Macintosh.
-
-Exactly one of the system-dependent modules should be configured into an
-installed JPEG library (see install.txt for hints about which one to use).
-On unusual systems you may find it worthwhile to make a special
-system-dependent memory manager.
-
-
-Non-C source code files:
-
-jmemdosa.asm 80x86 assembly code support for jmemdos.c; used only in
- MS-DOS-specific configurations of the JPEG library.
-
-

-
-C source code files:
-

-djpeg.c Main program for djpeg.
-jpegtran.c Main program for jpegtran.
-cdjpeg.c Utility routines used by all three programs.
-rdcolmap.c Code to read a colormap file for djpeg's "-map" switch.

-
-Image file reader modules for cjpeg:
-

-rdgif.c GIF file input (now just a stub).
-rdppm.c PPM/PGM file input.
-rdrle.c Utah RLE file input.
-rdtarga.c Targa file input.
-
-Image file writer modules for djpeg:
-

-wrgif.c GIF file output (a mere shadow of its former self).
-wrppm.c PPM/PGM file output.
-wrrle.c Utah RLE file output.

-
-C source code files:
-

-wrjpgcom.c Stand-alone wrjpgcom application.
-
-These programs do not depend on the IJG library. They do use
-jconfig.h and jinclude.h, only to improve portability.

-INSTALLATION INSTRUCTIONS for the Independent JPEG Group's JPEG software
-
-Copyright (C) 1991-2015, Thomas G. Lane, Guido Vollbeding.
-This file is part of the Independent JPEG Group's software.
-For conditions of distribution and use, see the accompanying README file.
-
-
-This file explains how to configure and install the IJG software. We have
-tried to make this software extremely portable and flexible, so that it can be
-adapted to almost any environment. The downside of this decision is that the
-installation process is complicated. We have provided shortcuts to simplify
-the task on common systems. But in any case, you will need at least a little
-familiarity with C programming and program build procedures for your system.
-
-If you are only using this software as part of a larger program, the larger
-program's installation procedure may take care of configuring the IJG code.
-For example, Ghostscript's installation script will configure the IJG code.
-You don't need to read this file if you just want to compile Ghostscript.
-
-If you are on a Unix machine, you may not need to read this file at all.
-Try doing
- ./configure
- make
- make test
-If that doesn't complain, do
- make install
-(better do "make -n install" first to see if the makefile will put the files
-where you want them). Read further if you run into snags or want to customize
-the code for your system.
-
-
-TABLE OF CONTENTS
------------------
-
-Before you start
-Configuring the software:
- using the automatic "configure" script
- using one of the supplied jconfig and makefile files
- by hand
-Building the software
-Testing the software
-Installing the software
-Optional stuff
-Optimization
-Hints for specific systems

-BEFORE YOU START
-================
-
-Before installing the software you must unpack the distributed source code.
-Since you are reading this file, you have probably already succeeded in this
-task. However, there is a potential for error if you needed to convert the
-files to the local standard text file format (for example, if you are on
-MS-DOS you may have converted LF end-of-line to CR/LF). You must apply
-such conversion to all the files EXCEPT those whose names begin with "test".
-The test files contain binary data; if you change them in any way then the
-self-test will give bad results.
-
-Please check the last section of this file to see if there are hints for the
-specific machine or compiler you are using.
-
-
-CONFIGURING THE SOFTWARE
-========================
-
-To configure the IJG code for your system, you need to create two files:
- * jconfig.h: contains values for system-dependent #define symbols.
- * Makefile: controls the compilation process.
-(On a non-Unix machine, you may create "project files" or some other
-substitute for a Makefile. jconfig.h is needed in any environment.)
-
-We provide three different ways to generate these files:
- * On a Unix system, you can just run the "configure" script.
- * We provide sample jconfig files and makefiles for popular machines;
- if your machine matches one of the samples, just copy the right sample
- files to jconfig.h and Makefile.
- * If all else fails, read the instructions below and make your own files.
-
-
-Configuring the software using the automatic "configure" script
----------------------------------------------------------------
-
-If you are on a Unix machine, you can just type
- ./configure
-and let the configure script construct appropriate configuration files.
-If you're using "csh" on an old version of System V, you might need to type
- sh configure
-instead to prevent csh from trying to execute configure itself.
-Expect configure to run for a few minutes, particularly on slower machines;
-it works by compiling a series of test programs.
-
-Configure was created with GNU Autoconf and it follows the usual conventions
-for GNU configure scripts. It makes a few assumptions that you may want to
-override. You can do this by providing optional switches to configure:
-
-* Configure will build both static and shared libraries, if possible.
-If you want to build libjpeg only as a static library, say
- ./configure --disable-shared
-If you want to build libjpeg only as a shared library, say
- ./configure --disable-static
-Configure uses GNU libtool to take care of system-dependent shared library
-building methods.
-
-* Configure will use gcc (GNU C compiler) if it's available, otherwise cc.
-To force a particular compiler to be selected, use the CC option, for example
- ./configure CC='cc'
-The same method can be used to include any unusual compiler switches.
-For example, on HP-UX you probably want to say
- ./configure CC='cc -Aa'
-to get HP's compiler to run in ANSI mode.
-
-* The default CFLAGS setting is "-g" for non-gcc compilers, "-g -O2" for gcc.
-You can override this by saying, for example,
- ./configure CFLAGS='-O2'
-if you want to compile without debugging support.
-
-* Configure will set up the makefile so that "make install" will install files
-into /usr/local/bin, /usr/local/man, etc. You can specify an installation
-prefix other than "/usr/local" by giving configure the option "--prefix=PATH".
-
-* If you don't have a lot of swap space, you may need to enable the IJG
-software's internal virtual memory mechanism. To do this, give the option
-"--enable-maxmem=N" where N is the default maxmemory limit in megabytes.
-This is discussed in more detail under "Selecting a memory manager", below.
-You probably don't need to worry about this on reasonably-sized Unix machines,
-unless you plan to process very large images.
-
-Configure has some other features that are useful if you are cross-compiling
-or working in a network of multiple machine types; but if you need those
-features, you probably already know how to use them.
-
-
-Configuring the software using one of the supplied jconfig and makefile files
------------------------------------------------------------------------------
-
-If you have one of these systems, you can just use the provided configuration
-files:
-
-Makefile jconfig file System and/or compiler
-
-makefile.manx jconfig.manx Amiga, Manx Aztec C
-makefile.sas jconfig.sas Amiga, SAS C
-makeproj.mac jconfig.mac Apple Macintosh, Metrowerks CodeWarrior
-mak*jpeg.st jconfig.st Atari ST/STE/TT, Pure C or Turbo C
-makefile.bcc jconfig.bcc MS-DOS or OS/2, Borland C
-makefile.dj jconfig.dj MS-DOS, DJGPP (Delorie's port of GNU C)
-makefile.mc6 jconfig.mc6 MS-DOS, Microsoft C (16-bit only)
-makefile.wat jconfig.wat MS-DOS, OS/2, or Windows NT, Watcom C
-makefile.vc jconfig.vc Windows NT/9x, MS Visual C++
-make*.vc6 jconfig.vc Windows NT/9x, MS Visual C++ 6
-make*.v10 jconfig.vc Windows NT/9x, MS Visual C++ 2010 (v10)
-makefile.b32 jconfig.vc Windows NT/9x, Borland C++ 32-bit (bcc32)
-makefile.mms jconfig.vms Digital VMS, with MMS software
-makefile.vms jconfig.vms Digital VMS, without MMS software
-
-Copy the proper jconfig file to jconfig.h and the makefile to Makefile (or
-whatever your system uses as the standard makefile name). For more info see
-the appropriate system-specific hints section near the end of this file.
-
-
-Configuring the software by hand
---------------------------------
-
-First, generate a jconfig.h file. If you are moderately familiar with C,
-the comments in jconfig.txt should be enough information to do this; just
-copy jconfig.txt to jconfig.h and edit it appropriately. Otherwise, you may
-prefer to use the ckconfig.c program. You will need to compile and execute
-ckconfig.c by hand --- we hope you know at least enough to do that.
-ckconfig.c may not compile the first try (in fact, the whole idea is for it
-to fail if anything is going to). If you get compile errors, fix them by
-editing ckconfig.c according to the directions given in ckconfig.c. Once
-you get it to run, it will write a suitable jconfig.h file, and will also
-print out some advice about which makefile to use.
-
-You may also want to look at the canned jconfig files, if there is one for a
-system similar to yours.
-
-Second, select a makefile and copy it to Makefile (or whatever your system
-uses as the standard makefile name). The most generic makefiles we provide
-are
- makefile.ansi: if your C compiler supports function prototypes
- makefile.unix: if not.
-(You have function prototypes if ckconfig.c put "#define HAVE_PROTOTYPES"
-in jconfig.h.) You may want to start from one of the other makefiles if
-there is one for a system similar to yours.
-
-Look over the selected Makefile and adjust options as needed. In particular
-you may want to change the CC and CFLAGS definitions. For instance, if you
-are using GCC, set CC=gcc. If you had to use any compiler switches to get
-ckconfig.c to work, make sure the same switches are in CFLAGS.
-
-If you are on a system that doesn't use makefiles, you'll need to set up
-project files (or whatever you do use) to compile all the source files and
-link them into executable files cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom.
-See the file lists in any of the makefiles to find out which files go into
-each program. Note that the provided makefiles all make a "library" file
-libjpeg first, but you don't have to do that if you don't want to; the file
-lists identify which source files are actually needed for compression,
-decompression, or both. As a last resort, you can make a batch script that
-just compiles everything and links it all together; makefile.vms is an example
-of this (it's for VMS systems that have no make-like utility).
-
-Here are comments about some specific configuration decisions you'll
-need to make:
-
-Command line style
-------------------
-
-These programs can use a Unix-like command line style which supports
-redirection and piping, like this:
- cjpeg inputfile >outputfile
- cjpeg outputfile
- source program | cjpeg >outputfile
-The simpler "two file" command line style is just
- cjpeg inputfile outputfile
-You may prefer the two-file style, particularly if you don't have pipes.
-
-You MUST use two-file style on any system that doesn't cope well with binary
-data fed through stdin/stdout; this is true for some MS-DOS compilers, for
-example. If you're not on a Unix system, it's safest to assume you need
-two-file style. (But if your compiler provides either the Posix-standard
-fdopen() library routine or a Microsoft-compatible setmode() routine, you
-can safely use the Unix command line style, by defining USE_FDOPEN or
-USE_SETMODE respectively.)
-
-To use the two-file style, make jconfig.h say "#define TWO_FILE_COMMANDLINE".
-
-Selecting a memory manager
---------------------------
-
-The IJG code is capable of working on images that are too big to fit in main
-memory; data is swapped out to temporary files as necessary. However, the
-code to do this is rather system-dependent. We provide five different
-memory managers:
-
-* jmemansi.c This version uses the ANSI-standard library routine tmpfile(),
- which not all non-ANSI systems have. On some systems
- tmpfile() may put the temporary file in a non-optimal
- location; if you don't like what it does, use jmemname.c.
-
-* jmemname.c This version creates named temporary files. For anything
- except a Unix machine, you'll need to configure the
- select_file_name() routine appropriately; see the comments
- near the head of jmemname.c. If you use this version, define
- NEED_SIGNAL_CATCHER in jconfig.h to make sure the temp files
- are removed if the program is aborted.
-
-* jmemnobs.c (That stands for No Backing Store :-).) This will compile on
- almost any system, but it assumes you have enough main memory
- or virtual memory to hold the biggest images you work with.
-
-* jmemdos.c This should be used with most 16-bit MS-DOS compilers.
- See the system-specific notes about MS-DOS for more info.
- IMPORTANT: if you use this, define USE_MSDOS_MEMMGR in
- jconfig.h, and include the assembly file jmemdosa.asm in the
- programs. The supplied makefiles and jconfig files for
- 16-bit MS-DOS compilers already do both.
-
-* jmemmac.c Custom version for Apple Macintosh; see the system-specific
- notes for Macintosh for more info.
-
-To use a particular memory manager, change the SYSDEPMEM variable in your
-makefile to equal the corresponding object file name (for example, jmemansi.o
-or jmemansi.obj for jmemansi.c).
-
-If you have plenty of (real or virtual) main memory, just use jmemnobs.c.
-"Plenty" means about ten bytes for every pixel in the largest images
-you plan to process, so a lot of systems don't meet this criterion.
-If yours doesn't, try jmemansi.c first. If that doesn't compile, you'll have
-to use jmemname.c; be sure to adjust select_file_name() for local conditions.
-You may also need to change unlink() to remove() in close_backing_store().
-
-Except with jmemnobs.c or jmemmac.c, you need to adjust the DEFAULT_MAX_MEM
-setting to a reasonable value for your system (either by adding a #define for
-DEFAULT_MAX_MEM to jconfig.h, or by adding a -D switch to the Makefile).
-This value limits the amount of data space the program will attempt to
-allocate. Code and static data space isn't counted, so the actual memory
-needs for cjpeg or djpeg are typically 100 to 150Kb more than the max-memory
-setting. Larger max-memory settings reduce the amount of I/O needed to
-process a large image, but too large a value can result in "insufficient
-memory" failures. On most Unix machines (and other systems with virtual
-memory), just set DEFAULT_MAX_MEM to several million and forget it. At the
-other end of the spectrum, for MS-DOS machines you probably can't go much
-above 300K to 400K. (On MS-DOS the value refers to conventional memory only.
-Extended/expanded memory is handled separately by jmemdos.c.)
-
-
-BUILDING THE SOFTWARE
-=====================
-
-Now you should be able to compile the software. Just say "make" (or
-whatever's necessary to start the compilation). Have a cup of coffee.
-
-Here are some things that could go wrong:
-
-If your compiler complains about undefined structures, you should be able to
-shut it up by putting "#define INCOMPLETE_TYPES_BROKEN" in jconfig.h.
-
-If you have trouble with missing system include files or inclusion of the
-wrong ones, read jinclude.h. This shouldn't happen if you used configure
-or ckconfig.c to set up jconfig.h.
-
-There are a fair number of routines that do not use all of their parameters;
-some compilers will issue warnings about this, which you can ignore. There
-are also a few configuration checks that may give "unreachable code" warnings.
-Any other warning deserves investigation.
-
-If you don't have a getenv() library routine, define NO_GETENV.
-
-Also see the system-specific hints, below.
-
-
-TESTING THE SOFTWARE
-====================
-
-As a quick test of functionality we've included a small sample image in
-several forms:
- testorig.jpg Starting point for the djpeg tests.
- testimg.ppm The output of djpeg testorig.jpg
- testimg.bmp The output of djpeg -bmp -colors 256 testorig.jpg
- testimg.jpg The output of cjpeg testimg.ppm
- testprog.jpg Progressive-mode equivalent of testorig.jpg.
- testimgp.jpg The output of cjpeg -progressive -optimize testimg.ppm
-(The first- and second-generation .jpg files aren't identical since the
-default compression parameters are lossy.) If you can generate duplicates
-of the testimg* files then you probably have working programs.
-
-With most of the makefiles, "make test" will perform the necessary
-comparisons.
-
-If you're using a makefile that doesn't provide the test option, run djpeg
-and cjpeg by hand and compare the output files to testimg* with whatever
-binary file comparison tool you have. The files should be bit-for-bit
-identical.
-
-If the programs complain "MAX_ALLOC_CHUNK is wrong, please fix", then you
-need to reduce MAX_ALLOC_CHUNK to a value that fits in type size_t.
-Try adding "#define MAX_ALLOC_CHUNK 65520L" to jconfig.h. A less likely
-configuration error is "ALIGN_TYPE is wrong, please fix": defining ALIGN_TYPE
-as long should take care of that one.
-
-If the cjpeg test run fails with "Missing Huffman code table entry", it's a
-good bet that you needed to define RIGHT_SHIFT_IS_UNSIGNED. Go back to the
-configuration step and run ckconfig.c. (This is a good plan for any other
-test failure, too.)
-
-If you are using Unix (one-file) command line style on a non-Unix system,
-it's a good idea to check that binary I/O through stdin/stdout actually
-works. You should get the same results from "djpeg out.ppm"
-as from "djpeg -outfile out.ppm testorig.jpg". Note that the makefiles all
-use the latter style and therefore do not exercise stdin/stdout! If this
-check fails, try recompiling with USE_SETMODE or USE_FDOPEN defined.
-If it still doesn't work, better use two-file style.
-
-If you chose a memory manager other than jmemnobs.c, you should test that
-temporary-file usage works. Try "djpeg -bmp -colors 256 -max 0 testorig.jpg"
-and make sure its output matches testimg.bmp. If you have any really large
-images handy, try compressing them with -optimize and/or decompressing with
--colors 256 to make sure your DEFAULT_MAX_MEM setting is not too large.
-
-NOTE: this is far from an exhaustive test of the JPEG software; some modules,
-such as 1-pass color quantization, are not exercised at all. It's just a
-quick test to give you some confidence that you haven't missed something
-major.
-
-
-INSTALLING THE SOFTWARE
-=======================
-
-Once you're done with the above steps, you can install the software by
-copying the executable files (cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom)
-to wherever you normally install programs. On Unix systems, you'll also want
-to put the man pages (cjpeg.1, djpeg.1, jpegtran.1, rdjpgcom.1, wrjpgcom.1)
-in the man-page directory. The pre-fab makefiles don't support this step
-since there's such a wide variety of installation procedures on different
-systems.
-
-If you generated a Makefile with the "configure" script, you can just say
- make install
-to install the programs and their man pages into the standard places.
-(You'll probably need to be root to do this.) We recommend first saying
- make -n install
-to see where configure thought the files should go. You may need to edit
-the Makefile, particularly if your system's conventions for man page
-filenames don't match what configure expects.
-
-If you want to install the IJG library itself, for use in compiling other
-programs besides ours, then you need to put the four include files
- jpeglib.h jerror.h jconfig.h jmorecfg.h
-into your include-file directory, and put the library file libjpeg.a
-(extension may vary depending on system) wherever library files go.
-If you generated a Makefile with "configure", it will do what it thinks
-is the right thing if you say
- make install-lib
-
-
-OPTIONAL STUFF
-==============
-
-Progress monitor:
-
-If you like, you can #define PROGRESS_REPORT (in jconfig.h) to enable display
-of percent-done progress reports. The routine provided in cdjpeg.c merely
-prints percentages to stderr, but you can customize it to do something
-fancier.
-
-Utah RLE file format support:
-
-We distribute the software with support for RLE image files (Utah Raster
-Toolkit format) disabled, because the RLE support won't compile without the
-Utah library. If you have URT version 3.1 or later, you can enable RLE
-support as follows:
- 1. #define RLE_SUPPORTED in jconfig.h.
- 2. Add a -I option to CFLAGS in the Makefile for the directory
- containing the URT .h files (typically the "include"
- subdirectory of the URT distribution).
- 3. Add -L... -lrle to LDLIBS in the Makefile, where ... specifies
- the directory containing the URT "librle.a" file (typically the
- "lib" subdirectory of the URT distribution).
-
-Support for 9-bit to 12-bit deep pixel data:
-
-The IJG code currently allows 8, 9, 10, 11, or 12 bits sample data precision.
-(For color, this means 8 to 12 bits per channel, of course.) If you need to
-work with deeper than 8-bit data, you can compile the IJG code for 9-bit to
-12-bit operation.
-To do so:
- 1. In jmorecfg.h, define BITS_IN_JSAMPLE as 9, 10, 11, or 12 rather than 8.
- 2. In jconfig.h, undefine BMP_SUPPORTED, RLE_SUPPORTED, and TARGA_SUPPORTED,
- because the code for those formats doesn't handle deeper than 8-bit data
- and won't even compile. (The PPM code does work, as explained below.
- The GIF code works too; it scales 8-bit GIF data to and from 12-bit
- depth automatically.)
- 3. Compile. Don't expect "make test" to pass, since the supplied test
- files are for 8-bit data.
-
-Currently, 9-bit to 12-bit support does not work on 16-bit-int machines.
-
-Run-time selection and conversion of data precision are currently not
-supported and may be added later.
-Exception: The transcoding part (jpegtran) supports all settings in a
-single instance, since it operates on the level of DCT coefficients and
-not sample values.
-
-The PPM reader (rdppm.c) can read deeper than 8-bit data from either
-text-format or binary-format PPM and PGM files. Binary-format PPM/PGM files
-which have a maxval greater than 255 are assumed to use 2 bytes per sample,
-MSB first (big-endian order). As of early 1995, 2-byte binary format is not
-officially supported by the PBMPLUS library, but it is expected that a
-future release of PBMPLUS will support it. Note that the PPM reader will
-read files of any maxval regardless of the BITS_IN_JSAMPLE setting; incoming
-data is automatically rescaled to maxval=MAXJSAMPLE as appropriate for the
-cjpeg bit depth.
-
-The PPM writer (wrppm.c) will normally write 2-byte binary PPM or PGM
-format, maxval=MAXJSAMPLE, when compiled with BITS_IN_JSAMPLE>8. Since this
-format is not yet widely supported, you can disable it by compiling wrppm.c
-with PPM_NORAWWORD defined; then the data is scaled down to 8 bits to make a
-standard 1-byte/sample PPM or PGM file. (Yes, this means still another copy
-of djpeg to keep around. But hopefully you won't need it for very long.
-Poskanzer's supposed to get that new PBMPLUS release out Real Soon Now.)
-
-Of course, if you are working with 9-bit to 12-bit data, you probably have
-it stored in some other, nonstandard format. In that case you'll probably
-want to write your own I/O modules to read and write your format.
-
-Note:
-The standard Huffman tables are only valid for 8-bit data precision. If
-you selected more than 8-bit data precision, cjpeg uses arithmetic coding
-by default. The Huffman encoder normally uses entropy optimization to
-compute usable tables for higher precision. Otherwise, you'll have to
-supply different default Huffman tables.
-
-Removing code:
-
-If you need to make a smaller version of the JPEG software, some optional
-functions can be removed at compile time. See the xxx_SUPPORTED #defines in
-jconfig.h and jmorecfg.h. If at all possible, we recommend that you leave in
-decoder support for all valid JPEG files, to ensure that you can read anyone's
-output. Taking out support for image file formats that you don't use is the
-most painless way to make the programs smaller. Another possibility is to
-remove some of the DCT methods: in particular, the "IFAST" method may not be
-enough faster than the others to be worth keeping on your machine. (If you
-do remove ISLOW or IFAST, be sure to redefine JDCT_DEFAULT or JDCT_FASTEST
-to a supported method, by adding a #define in jconfig.h.)
-
-
-OPTIMIZATION
-============
-
-Unless you own a Cray, you'll probably be interested in making the JPEG
-software go as fast as possible. This section covers some machine-dependent
-optimizations you may want to try. We suggest that before trying any of
-this, you first get the basic installation to pass the self-test step.
-Repeat the self-test after any optimization to make sure that you haven't
-broken anything.
-
-The integer DCT routines perform a lot of multiplications. These
-multiplications must yield 32-bit results, but none of their input values
-are more than 16 bits wide. On many machines, notably the 680x0 and 80x86
-CPUs, a 16x16=>32 bit multiply instruction is faster than a full 32x32=>32
-bit multiply. Unfortunately there is no portable way to specify such a
-multiplication in C, but some compilers can generate one when you use the
-right combination of casts. See the MULTIPLYxxx macro definitions in
-jdct.h. If your compiler makes "int" be 32 bits and "short" be 16 bits,
-defining SHORTxSHORT_32 is fairly likely to work. When experimenting with
-alternate definitions, be sure to test not only whether the code still works
-(use the self-test), but also whether it is actually faster --- on some
-compilers, alternate definitions may compute the right answer, yet be slower
-than the default. Timing cjpeg on a large PGM (grayscale) input file is the
-best way to check this, as the DCT will be the largest fraction of the runtime
-in that mode. (Note: some of the distributed compiler-specific jconfig files
-already contain #define switches to select appropriate MULTIPLYxxx
-definitions.)
-
-If your machine has sufficiently fast floating point hardware, you may find
-that the float DCT method is faster than the integer DCT methods, even
-after tweaking the integer multiply macros. In that case you may want to
-make the float DCT be the default method. (The only objection to this is
-that float DCT results may vary slightly across machines.) To do that, add
-"#define JDCT_DEFAULT JDCT_FLOAT" to jconfig.h. Even if you don't change
-the default, you should redefine JDCT_FASTEST, which is the method selected
-by djpeg's -fast switch. Don't forget to update the documentation files
-(usage.txt and/or cjpeg.1, djpeg.1) to agree with what you've done.
-
-If access to "short" arrays is slow on your machine, it may be a win to
-define type JCOEF as int rather than short. This will cost a good deal of
-memory though, particularly in some multi-pass modes, so don't do it unless
-you have memory to burn and short is REALLY slow.
-
-If your compiler can compile function calls in-line, make sure the INLINE
-macro in jmorecfg.h is defined as the keyword that marks a function
-inline-able. Some compilers have a switch that tells the compiler to inline
-any function it thinks is profitable (e.g., -finline-functions for gcc).
-Enabling such a switch is likely to make the compiled code bigger but faster.
-
-In general, it's worth trying the maximum optimization level of your compiler,
-and experimenting with any optional optimizations such as loop unrolling.
-(Unfortunately, far too many compilers have optimizer bugs ... be prepared to
-back off if the code fails self-test.) If you do any experimentation along
-these lines, please report the optimal settings to jpeg-info@jpegclub.org so
-we can mention them in future releases. Be sure to specify your machine and
-compiler version.
-
-
-HINTS FOR SPECIFIC SYSTEMS
-==========================
-
-We welcome reports on changes needed for systems not mentioned here. Submit
-'em to jpeg-info@jpegclub.org. Also, if configure or ckconfig.c is wrong
-about how to configure the JPEG software for your system, please let us know.
-
-
-Acorn RISC OS:
-
-(Thanks to Simon Middleton for these hints on compiling with Desktop C.)
-After renaming the files according to Acorn conventions, take a copy of
-makefile.ansi, change all occurrences of 'libjpeg.a' to 'libjpeg.o' and
-change these definitions as indicated:
-
-CFLAGS= -throwback -IC: -Wn
-LDLIBS=C:o.Stubs
-SYSDEPMEM=jmemansi.o
-LN=Link
-AR=LibFile -c -o
-
-Also add a new line '.c.o:; $(cc) $< $(cflags) -c -o $@'. Remove the
-lines '$(RM) libjpeg.o' and '$(AR2) libjpeg.o' and the 'jconfig.h'
-dependency section.
-
-Copy jconfig.txt to jconfig.h. Edit jconfig.h to define TWO_FILE_COMMANDLINE
-and CHAR_IS_UNSIGNED.
-
-Run the makefile using !AMU not !Make. If you want to use the 'clean' and
-'test' makefile entries then you will have to fiddle with the syntax a bit
-and rename the test files.
-
-
-Amiga:
-
-SAS C 6.50 reportedly is too buggy to compile the IJG code properly.
-A patch to update to 6.51 is available from SAS or AmiNet FTP sites.
-
-The supplied config files are set up to use jmemname.c as the memory
-manager, with temporary files being created on the device named by
-"JPEGTMP:".
-
-
-Atari ST/STE/TT:
-
-Copy the project files makcjpeg.st, makdjpeg.st, maktjpeg.st, and makljpeg.st
-to cjpeg.prj, djpeg.prj, jpegtran.prj, and libjpeg.prj respectively. The
-project files should work as-is with Pure C. For Turbo C, change library
-filenames "pc..." to "tc..." in each project file. Note that libjpeg.prj
-selects jmemansi.c as the recommended memory manager. You'll probably want to
-adjust the DEFAULT_MAX_MEM setting --- you want it to be a couple hundred K
-less than your normal free memory. Put "#define DEFAULT_MAX_MEM nnnn" into
-jconfig.h to do this.
-
-To use the 68881/68882 coprocessor for the floating point DCT, add the
-compiler option "-8" to the project files and replace pcfltlib.lib with
-pc881lib.lib in cjpeg.prj and djpeg.prj. Or if you don't have a
-coprocessor, you may prefer to remove the float DCT code by undefining
-DCT_FLOAT_SUPPORTED in jmorecfg.h (since without a coprocessor, the float
-code will be too slow to be useful). In that case, you can delete
-pcfltlib.lib from the project files.
-
-Note that you must make libjpeg.lib before making cjpeg.ttp, djpeg.ttp,
-or jpegtran.ttp. You'll have to perform the self-test by hand.
-
-We haven't bothered to include project files for rdjpgcom and wrjpgcom.
-Those source files should just be compiled by themselves; they don't
-depend on the JPEG library. You can use the default.prj project file
-of the Pure C distribution to make the programs.
-
-There is a bug in some older versions of the Turbo C library which causes the
-space used by temporary files created with "tmpfile()" not to be freed after
-an abnormal program exit. If you check your disk afterwards, you will find
-cluster chains that are allocated but not used by a file. This should not
-happen in cjpeg/djpeg/jpegtran, since we enable a signal catcher to explicitly
-close temp files before exiting. But if you use the JPEG library with your
-own code, be sure to supply a signal catcher, or else use a different
-system-dependent memory manager.
-
-
-Cray:
-
-Should you be so fortunate as to be running JPEG on a Cray YMP, there is a
-compiler bug in old versions of Cray's Standard C (prior to 3.1). If you
-still have an old compiler, you'll need to insert a line reading
-"#pragma novector" just before the loop
- for (i = 1; i <= (int) htbl->bits[l]; i++)
- huffsize[p++] = (char) l;
-in fix_huff_tbl (in V5beta1, line 204 of jchuff.c and line 176 of jdhuff.c).
-[This bug may or may not still occur with the current IJG code, but it's
-probably a dead issue anyway...]
-
-
-HP-UX:
-
-If you have HP-UX 7.05 or later with the "software development" C compiler,
-you should run the compiler in ANSI mode. If using the configure script,
-say
- ./configure CC='cc -Aa'
-(or -Ae if you prefer). If configuring by hand, use makefile.ansi and add
-"-Aa" to the CFLAGS line in the makefile.
-
-If you have a pre-7.05 system, or if you are using the non-ANSI C compiler
-delivered with a minimum HP-UX system, then you must use makefile.unix
-(and do NOT add -Aa); or just run configure without the CC option.
-
-On HP 9000 series 800 machines, the HP C compiler is buggy in revisions prior
-to A.08.07. If you get complaints about "not a typedef name", you'll have to
-use makefile.unix, or run configure without the CC option.
-
-
-Macintosh, generic comments:
-
-The supplied user-interface files (cjpeg.c, djpeg.c, etc) are set up to
-provide a Unix-style command line interface. You can use this interface on
-the Mac by means of the ccommand() library routine provided by Metrowerks
-CodeWarrior or Think C. This is only appropriate for testing the library,
-however; to make a user-friendly equivalent of cjpeg/djpeg you'd really want
-to develop a Mac-style user interface. There isn't a complete example
-available at the moment, but there are some helpful starting points:
-1. Sam Bushell's free "To JPEG" applet provides drag-and-drop conversion to
-JPEG under System 7 and later. This only illustrates how to use the
-compression half of the library, but it does a very nice job of that part.
-The CodeWarrior source code is available from http://www.pobox.com/~jsam.
-2. Jim Brunner prepared a Mac-style user interface for both compression and
-decompression. Unfortunately, it hasn't been updated since IJG v4, and
-the library's API has changed considerably since then. Still it may be of
-some help, particularly as a guide to compiling the IJG code under Think C.
-Jim's code is available from the Info-Mac archives, at sumex-aim.stanford.edu
-or mirrors thereof; see file /info-mac/dev/src/jpeg-convert-c.hqx.
-
-jmemmac.c is the recommended memory manager back end for Macintosh. It uses
-NewPtr/DisposePtr instead of malloc/free, and has a Mac-specific
-implementation of jpeg_mem_available(). It also creates temporary files that
-follow Mac conventions. (That part of the code relies on System-7-or-later OS
-functions. See the comments in jmemmac.c if you need to run it on System 6.)
-NOTE that USE_MAC_MEMMGR must be defined in jconfig.h to use jmemmac.c.
-
-You can also use jmemnobs.c, if you don't care about handling images larger
-than available memory. If you use any memory manager back end other than
-jmemmac.c, we recommend replacing "malloc" and "free" by "NewPtr" and
-"DisposePtr", because Mac C libraries often have peculiar implementations of
-malloc/free. (For instance, free() may not return the freed space to the
-Mac Memory Manager. This is undesirable for the IJG code because jmemmgr.c
-already clumps space requests.)
-
-
-Macintosh, Metrowerks CodeWarrior:
-
-The Unix-command-line-style interface can be used by defining USE_CCOMMAND.
-You'll also need to define TWO_FILE_COMMANDLINE to avoid stdin/stdout.
-This means that when using the cjpeg/djpeg programs, you'll have to type the
-input and output file names in the "Arguments" text-edit box, rather than
-using the file radio buttons. (Perhaps USE_FDOPEN or USE_SETMODE would
-eliminate the problem, but I haven't heard from anyone who's tried it.)
-
-On 680x0 Macs, Metrowerks defines type "double" as a 10-byte IEEE extended
-float. jmemmgr.c won't like this: it wants sizeof(ALIGN_TYPE) to be a power
-of 2. Add "#define ALIGN_TYPE long" to jconfig.h to eliminate the complaint.
-
-The supplied configuration file jconfig.mac can be used for your jconfig.h;
-it includes all the recommended symbol definitions. If you have AppleScript
-installed, you can run the supplied script makeproj.mac to create CodeWarrior
-project files for the library and the testbed applications, then build the
-library and applications. (Thanks to Dan Sears and Don Agro for this nifty
-hack, which saves us from trying to maintain CodeWarrior project files as part
-of the IJG distribution...)
-
-
-Macintosh, Think C:
-
-The documentation in Jim Brunner's "JPEG Convert" source code (see above)
-includes detailed build instructions for Think C; it's probably somewhat
-out of date for the current release, but may be helpful.
-
-If you want to build the minimal command line version, proceed as follows.
-You'll have to prepare project files for the programs; we don't include any
-in the distribution since they are not text files. Use the file lists in
-any of the supplied makefiles as a guide. Also add the ANSI and Unix C
-libraries in a separate segment. You may need to divide the JPEG files into
-more than one segment; we recommend dividing compression and decompression
-modules. Define USE_CCOMMAND in jconfig.h so that the ccommand() routine is
-called. You must also define TWO_FILE_COMMANDLINE because stdin/stdout
-don't handle binary data correctly.
-
-On 680x0 Macs, Think C defines type "double" as a 12-byte IEEE extended float.
-jmemmgr.c won't like this: it wants sizeof(ALIGN_TYPE) to be a power of 2.
-Add "#define ALIGN_TYPE long" to jconfig.h to eliminate the complaint.
-
-jconfig.mac should work as a jconfig.h configuration file for Think C,
-but the makeproj.mac AppleScript script is specific to CodeWarrior. Sorry.
-
-
-MIPS R3000:
-
-MIPS's cc version 1.31 has a rather nasty optimization bug. Don't use -O
-if you have that compiler version. (Use "cc -V" to check the version.)
-Note that the R3000 chip is found in workstations from DEC and others.
-
-
-MS-DOS, generic comments for 16-bit compilers:
-
-The IJG code is designed to work well in 80x86 "small" or "medium" memory
-models (i.e., data pointers are 16 bits unless explicitly declared "far";
-code pointers can be either size). You may be able to use small model to
-compile cjpeg or djpeg by itself, but you will probably have to use medium
-model for any larger application. This won't make much difference in
-performance. You *will* take a noticeable performance hit if you use a
-large-data memory model, and you should avoid "huge" model if at all
-possible. Be sure that NEED_FAR_POINTERS is defined in jconfig.h if you use
-a small-data memory model; be sure it is NOT defined if you use a large-data
-model. (The supplied makefiles and jconfig files for Borland and Microsoft C
-compile in medium model and define NEED_FAR_POINTERS.)
-
-The DOS-specific memory manager, jmemdos.c, should be used if possible.
-It needs some assembly-code routines which are in jmemdosa.asm; make sure
-your makefile assembles that file and includes it in the library. If you
-don't have a suitable assembler, you can get pre-assembled object files for
-jmemdosa by FTP from ftp.uu.net:/graphics/jpeg/jdosaobj.zip. (DOS-oriented
-distributions of the IJG source code often include these object files.)
-
-When using jmemdos.c, jconfig.h must define USE_MSDOS_MEMMGR and must set
-MAX_ALLOC_CHUNK to less than 64K (65520L is a typical value). If your
-C library's far-heap malloc() can't allocate blocks that large, reduce
-MAX_ALLOC_CHUNK to whatever it can handle.
-
-If you can't use jmemdos.c for some reason --- for example, because you
-don't have an assembler to assemble jmemdosa.asm --- you'll have to fall
-back to jmemansi.c or jmemname.c. You'll probably still need to set
-MAX_ALLOC_CHUNK in jconfig.h, because most DOS C libraries won't malloc()
-more than 64K at a time. IMPORTANT: if you use jmemansi.c or jmemname.c,
-you will have to compile in a large-data memory model in order to get the
-right stdio library. Too bad.
-
-wrjpgcom needs to be compiled in large model, because it malloc()s a 64KB
-work area to hold the comment text. If your C library's malloc can't
-handle that, reduce MAX_COM_LENGTH as necessary in wrjpgcom.c.
-
-Most MS-DOS compilers treat stdin/stdout as text files, so you must use
-two-file command line style. But if your compiler has either fdopen() or
-setmode(), you can use one-file style if you like. To do this, define
-USE_SETMODE or USE_FDOPEN so that stdin/stdout will be set to binary mode.
-(USE_SETMODE seems to work with more DOS compilers than USE_FDOPEN.) You
-should test that I/O through stdin/stdout produces the same results as I/O
-to explicitly named files... the "make test" procedures in the supplied
-makefiles do NOT use stdin/stdout.
-
-
-MS-DOS, generic comments for 32-bit compilers:
-
-None of the above comments about memory models apply if you are using a
-32-bit flat-memory-space environment, such as DJGPP or Watcom C. (And you
-should use one if you have it, as performance will be much better than
-8086-compatible code!) For flat-memory-space compilers, do NOT define
-NEED_FAR_POINTERS, and do NOT use jmemdos.c. Use jmemnobs.c if the
-environment supplies adequate virtual memory, otherwise use jmemansi.c or
-jmemname.c.
-
-You'll still need to be careful about binary I/O through stdin/stdout.
-See the last paragraph of the previous section.
-
-
-MS-DOS, Borland C:
-
-Be sure to convert all the source files to DOS text format (CR/LF newlines).
-Although Borland C will often work OK with unmodified Unix (LF newlines)
-source files, sometimes it will give bogus compile errors.
-"Illegal character '#'" is the most common such error. (This is true with
-Borland C 3.1, but perhaps is fixed in newer releases.)
-
-If you want one-file command line style, just undefine TWO_FILE_COMMANDLINE.
-jconfig.bcc already includes #define USE_SETMODE to make this work.
-(fdopen does not work correctly.)
-
-
-MS-DOS, Microsoft C:
-
-makefile.mc6 works with Microsoft C, DOS Visual C++, etc. It should only
-be used if you want to build a 16-bit (small or medium memory model) program.
-
-If you want one-file command line style, just undefine TWO_FILE_COMMANDLINE.
-jconfig.mc6 already includes #define USE_SETMODE to make this work.
-(fdopen does not work correctly.)
-
-Note that this makefile assumes that the working copy of itself is called
-"makefile". If you want to call it something else, say "makefile.mak",
-be sure to adjust the dependency line that reads "$(RFILE) : makefile".
-Otherwise the make will fail because it doesn't know how to create "makefile".
-Worse, some releases of Microsoft's make utilities give an incorrect error
-message in this situation.
-
-Old versions of MS C fail with an "out of macro expansion space" error
-because they can't cope with the macro TRACEMS8 (defined in jerror.h).
-If this happens to you, the easiest solution is to change TRACEMS8 to
-expand to nothing. You'll lose the ability to dump out JPEG coefficient
-tables with djpeg -debug -debug, but at least you can compile.
-
-Original MS C 6.0 is very buggy; it compiles incorrect code unless you turn
-off optimization entirely (remove -O from CFLAGS). 6.00A is better, but it
-still generates bad code if you enable loop optimizations (-Ol or -Ox).
-
-MS C 8.0 crashes when compiling jquant1.c with optimization switch /Oo ...
-which is on by default. To work around this bug, compile that one file
-with /Oo-.
-
-
-Microsoft Windows (all versions), generic comments:
-
-Some Windows system include files define typedef boolean as "unsigned char".
-The IJG code also defines typedef boolean, but we make it an "enum" by default.
-This doesn't affect the IJG programs because we don't import those Windows
-include files. But if you use the JPEG library in your own program, and some
-of your program's files import one definition of boolean while some import the
-other, you can get all sorts of mysterious problems. A good preventive step
-is to make the IJG library use "unsigned char" for boolean. To do that,
-add something like this to your jconfig.h file:
- /* Define "boolean" as unsigned char, not enum, per Windows custom */
- #ifndef __RPCNDR_H__ /* don't conflict if rpcndr.h already read */
- typedef unsigned char boolean;
- #endif
- #ifndef FALSE /* in case these macros already exist */
- #define FALSE 0 /* values of boolean */
- #endif
- #ifndef TRUE
- #define TRUE 1
- #endif
- #define HAVE_BOOLEAN /* prevent jmorecfg.h from redefining it */
-(This is already in jconfig.vc, by the way.)
-
-windef.h contains the declarations
- #define far
- #define FAR far
-Since jmorecfg.h tries to define FAR as empty, you may get a compiler
-warning if you include both jpeglib.h and windef.h (which windows.h
-includes). To suppress the warning, you can put "#ifndef FAR"/"#endif"
-around the line "#define FAR" in jmorecfg.h.
-(Something like this is already in jmorecfg.h, by the way.)
-
-When using the library in a Windows application, you will almost certainly
-want to modify or replace the error handler module jerror.c, since our
-default error handler does a couple of inappropriate things:
- 1. it tries to write error and warning messages on stderr;
- 2. in event of a fatal error, it exits by calling exit().
-
-A simple stopgap solution for problem 1 is to replace the line
- fprintf(stderr, "%s\n", buffer);
-(in output_message in jerror.c) with
- MessageBox(GetActiveWindow(),buffer,"JPEG Error",MB_OK|MB_ICONERROR);
-It's highly recommended that you at least do that much, since otherwise
-error messages will disappear into nowhere. (Beginning with IJG v6b, this
-code is already present in jerror.c; just define USE_WINDOWS_MESSAGEBOX in
-jconfig.h to enable it.)
-
-The proper solution for problem 2 is to return control to your calling
-application after a library error. This can be done with the setjmp/longjmp
-technique discussed in libjpeg.txt and illustrated in example.c. (NOTE:
-some older Windows C compilers provide versions of setjmp/longjmp that
-don't actually work under Windows. You may need to use the Windows system
-functions Catch and Throw instead.)
-
-The recommended memory manager under Windows is jmemnobs.c; in other words,
-let Windows do any virtual memory management needed. You should NOT use
-jmemdos.c nor jmemdosa.asm under Windows.
-
-For Windows 3.1, we recommend compiling in medium or large memory model;
-for newer Windows versions, use a 32-bit flat memory model. (See the MS-DOS
-sections above for more info about memory models.) In the 16-bit memory
-models only, you'll need to put
- #define MAX_ALLOC_CHUNK 65520L /* Maximum request to malloc() */
-into jconfig.h to limit allocation chunks to 64Kb. (Without that, you'd
-have to use huge memory model, which slows things down unnecessarily.)
-jmemnobs.c works without modification in large or flat memory models, but to
-use medium model, you need to modify its jpeg_get_large and jpeg_free_large
-routines to allocate far memory. In any case, you might like to replace
-its calls to malloc and free with direct calls on Windows memory allocation
-functions.
-
-You may also want to modify jdatasrc.c and jdatadst.c to use Windows file
-operations rather than fread/fwrite. This is only necessary if your C
-compiler doesn't provide a competent implementation of C stdio functions.
-
-You might want to tweak the RGB_xxx macros in jmorecfg.h so that the library
-will accept or deliver color pixels in BGR sample order, not RGB; BGR order
-is usually more convenient under Windows. Note that this change will break
-the sample applications cjpeg/djpeg, but the library itself works fine.
-
-
-Many people want to convert the IJG library into a DLL. This is reasonably
-straightforward, but watch out for the following:
-
- 1. Don't try to compile as a DLL in small or medium memory model; use
-large model, or even better, 32-bit flat model. Many places in the IJG code
-assume the address of a local variable is an ordinary (not FAR) pointer;
-that isn't true in a medium-model DLL.
-
- 2. Microsoft C cannot pass file pointers between applications and DLLs.
-(See Microsoft Knowledge Base, PSS ID Number Q50336.) So jdatasrc.c and
-jdatadst.c don't work if you open a file in your application and then pass
-the pointer to the DLL. One workaround is to make jdatasrc.c/jdatadst.c
-part of your main application rather than part of the DLL.
-
- 3. You'll probably need to modify the macros GLOBAL() and EXTERN() to
-attach suitable linkage keywords to the exported routine names. Similarly,
-you'll want to modify METHODDEF() and JMETHOD() to ensure function pointers
-are declared in a way that lets application routines be called back through
-the function pointers. These macros are in jmorecfg.h. Typical definitions
-for a 16-bit DLL are:
- #define GLOBAL(type) type _far _pascal _loadds _export
- #define EXTERN(type) extern type _far _pascal _loadds
- #define METHODDEF(type) static type _far _pascal
- #define JMETHOD(type,methodname,arglist) \
- type (_far _pascal *methodname) arglist
-For a 32-bit DLL you may want something like
- #define GLOBAL(type) __declspec(dllexport) type
- #define EXTERN(type) extern __declspec(dllexport) type
-Although not all the GLOBAL routines are actually intended to be called by
-the application, the performance cost of making them all DLL entry points is
-negligible.
-
-The unmodified IJG library presents a very C-specific application interface,
-so the resulting DLL is only usable from C or C++ applications. There has
-been some talk of writing wrapper code that would present a simpler interface
-usable from other languages, such as Visual Basic. This is on our to-do list
-but hasn't been very high priority --- any volunteers out there?
-
-
-Microsoft Windows, Borland C:
-
-The provided jconfig.bcc should work OK in a 32-bit Windows environment,
-but you'll need to tweak it in a 16-bit environment (you'd need to define
-NEED_FAR_POINTERS and MAX_ALLOC_CHUNK). Beware that makefile.bcc will need
-alteration if you want to use it for Windows --- in particular, you should
-use jmemnobs.c not jmemdos.c under Windows.
-
-Borland C++ 4.5 fails with an internal compiler error when trying to compile
-jdmerge.c in 32-bit mode. If enough people complain, perhaps Borland will fix
-it. In the meantime, the simplest known workaround is to add a redundant
-definition of the variable range_limit in h2v1_merged_upsample(), at the head
-of the block that handles odd image width (about line 268 in v6 jdmerge.c):
- /* If image width is odd, do the last output column separately */
- if (cinfo->output_width & 1) {
- register JSAMPLE * range_limit = cinfo->sample_range_limit; /* ADD THIS */
- cb = GETJSAMPLE(*inptr1);
-Pretty bizarre, especially since the very similar routine h2v2_merged_upsample
-doesn't trigger the bug.
-Recent reports suggest that this bug does not occur with "bcc32a" (the
-Pentium-optimized version of the compiler).
-
-Another report from a user of Borland C 4.5 was that incorrect code (leading
-to a color shift in processed images) was produced if any of the following
-optimization switch combinations were used:
- -Ot -Og
- -Ot -Op
- -Ot -Om
-So try backing off on optimization if you see such a problem. (Are there
-several different releases all numbered "4.5"??)
-
-
-Microsoft Windows, Microsoft Visual C++:
-
-jconfig.vc should work OK with any Microsoft compiler for a 32-bit memory
-model. makefile.vc is intended for command-line use. (If you are using
-the Developer Studio environment, you may prefer the DevStudio project
-files; see below.)
-
-IJG JPEG 7 adds extern "C" to jpeglib.h. This avoids the need to put
-extern "C" { ... } around #include "jpeglib.h" in your C++ application.
-You can also force VC++ to treat the library as C++ code by renaming
-all the *.c files to *.cpp (and adjusting the makefile to match).
-In this case you also need to define the symbol DONT_USE_EXTERN_C in
-the configuration to prevent jpeglib.h from using extern "C".
-
-
-Microsoft Windows, Microsoft Visual C++ 6 Developer Studio:
-
-We include makefiles that should work as project files in DevStudio 6.0 or
-later. There is a library makefile that builds the IJG library as a static
-Win32 library, and application makefiles that build the sample applications
-as Win32 console applications. (Even if you only want the library, we
-recommend building the applications so that you can run the self-test.)
-
-To use:
-1. Open the command prompt, change to the main directory and execute the
- command line
- NMAKE /f makefile.vc setup-vc6
- This will move jconfig.vc to jconfig.h and makefiles to project files.
- (Note that the renaming is critical!)
-2. Open the workspace file jpeg.dsw, build the library project.
- (If you are using DevStudio more recent than 6.0, you'll probably
- get a message saying that the project files are being updated.)
-3. Open the workspace file apps.dsw, build the application projects.
-4. To perform the self-test, execute the command line
- NMAKE /f makefile.vc test-build
-5. Move the application .exe files from `app`\Release to an
- appropriate location on your path.
-
-
-Microsoft Windows, Microsoft Visual C++ 2010 Developer Studio (v10):
-
-We include makefiles that should work as project files in Visual Studio
-2010 or later. There is a library makefile that builds the IJG library
-as a static Win32 library, and application makefiles that build the sample
-applications as Win32 console applications. (Even if you only want the
-library, we recommend building the applications so that you can run the
-self-test.)
-
-To use:
-1. Open the command prompt, change to the main directory and execute the
- command line
- NMAKE /f makefile.vc setup-v10
- This will move jconfig.vc to jconfig.h and makefiles to project files.
- (Note that the renaming is critical!)
-2. Open the solution file jpeg.sln, build the library project.
- (If you are using Visual Studio more recent than 2010 (v10), you'll
- probably get a message saying that the project files are being updated.)
-3. Open the solution file apps.sln, build the application projects.
-4. To perform the self-test, execute the command line
- NMAKE /f makefile.vc test-build
-5. Move the application .exe files from `app`\Release to an
- appropriate location on your path.
-
-Note:
-There seems to be an optimization bug in the compiler which causes the
-self-test to fail with the color quantization option.
-We have disabled optimization for the file jquant2.c in the library
-project file which causes the self-test to pass properly.
-
-
-OS/2, Borland C++:
-
-Watch out for optimization bugs in older Borland compilers; you may need
-to back off the optimization switch settings. See the comments in
-makefile.bcc.
-
-
-SGI:
-
-On some SGI systems, you may need to set "AR2= ar -ts" in the Makefile.
-If you are using configure, you can do this by saying
- ./configure RANLIB='ar -ts'
-This change is not needed on all SGIs. Use it only if the make fails at the
-stage of linking the completed programs.
-
-On the MIPS R4000 architecture (Indy, etc.), the compiler option "-mips2"
-reportedly speeds up the float DCT method substantially, enough to make it
-faster than the default int method (but still slower than the fast int
-method). If you use -mips2, you may want to alter the default DCT method to
-be float. To do this, put "#define JDCT_DEFAULT JDCT_FLOAT" in jconfig.h.
-
-
-VMS:
-
-On an Alpha/VMS system with MMS, be sure to use the "/Marco=Alpha=1"
-qualifier with MMS when building the JPEG package.
-
-VAX/VMS v5.5-1 may have problems with the test step of the build procedure
-reporting differences when it compares the original and test images. If the
-error points to the last block of the files, it is most likely bogus and may
-be safely ignored. It seems to be because the files are Stream_LF and
-Backup/Compare has difficulty with the (presumably) null padded files.
-This problem was not observed on VAX/VMS v6.1 or AXP/VMS v6.1.

-/**************** RGB -> YCbCr conversion: most common case **************/
-
-/*
- * YCbCr is defined per Recommendation ITU-R BT.601-7 (03/2011),
- * previously known as Recommendation CCIR 601-1, except that Cb and Cr
- * are normalized to the range 0..MAXJSAMPLE rather than -0.5 .. 0.5.
- * sRGB (standard RGB color space) is defined per IEC 61966-2-1:1999.
- * sYCC (standard luma-chroma-chroma color space with extended gamut)
- * is defined per IEC 61966-2-1:1999 Amendment A1:2003 Annex F.
- * bg-sRGB and bg-sYCC (big gamut standard color spaces)
- * are defined per IEC 61966-2-1:1999 Amendment A1:2003 Annex G.
- * Note that the derived conversion coefficients given in some of these
- * documents are imprecise. The general conversion equations are
- * Y = Kr * R + (1 - Kr - Kb) * G + Kb * B
- * Cb = 0.5 * (B - Y) / (1 - Kb)
- * Cr = 0.5 * (R - Y) / (1 - Kr)
- * With Kr = 0.299 and Kb = 0.114 (derived according to SMPTE RP 177-1993
- * from the 1953 FCC NTSC primaries and CIE Illuminant C),
- * the conversion equations to be implemented are therefore
- * Y = 0.299 * R + 0.587 * G + 0.114 * B
- * Cb = -0.168735892 * R - 0.331264108 * G + 0.5 * B + CENTERJSAMPLE
- * Cr = 0.5 * R - 0.418687589 * G - 0.081312411 * B + CENTERJSAMPLE
- * Note: older versions of the IJG code used a zero offset of MAXJSAMPLE/2,
- * rather than CENTERJSAMPLE, for Cb and Cr. This gave equal positive and
- * negative swings for Cb/Cr, but meant that grayscale values (Cb=Cr=0)
- * were not represented exactly. Now we sacrifice exact representation of
- * maximum red and maximum blue in order to get exact grayscales.
- *
- * To avoid floating-point arithmetic, we represent the fractional constants
- * as integers scaled up by 2^16 (about 4 digits precision); we have to divide
- * the products by 2^16, with appropriate rounding, to get the correct answer.
- *
- * For even more speed, we avoid doing any multiplications in the inner loop
- * by precalculating the constants times R,G,B for all possible values.
- * For 8-bit JSAMPLEs this is very reasonable (only 256 entries per table);
- * for 9-bit to 12-bit samples it is still acceptable. It's not very
- * reasonable for 16-bit samples, but if you want lossless storage you
- * shouldn't be changing colorspace anyway.
- * The CENTERJSAMPLE offsets and the rounding fudge-factor of 0.5 are included
- * in the tables to save adding them separately in the inner loop.

- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains downsampling routines.
- *
- * Downsampling input data is counted in "row groups". A row group
- * is defined to be max_v_samp_factor pixel rows of each component,
- * from which the downsampler produces v_samp_factor sample rows.
- * A single row group is processed in each call to the downsampler module.
- *
- * The downsampler is responsible for edge-expansion of its output data
- * to fill an integral number of DCT blocks horizontally. The source buffer
- * may be modified if it is helpful for this purpose (the source buffer is
- * allocated wide enough to correspond to the desired output width).
- * The caller (the prep controller) is responsible for vertical padding.
- *
- * The downsampler may request "context rows" by setting need_context_rows
- * during startup. In this case, the input arrays will contain at least
- * one row group's worth of pixels above and below the passed-in data;
- * the caller will create dummy rows at image top and bottom by replicating
- * the first or last real pixel row.
- *
- * An excellent reference for image resampling is
- * Digital Image Warping, George Wolberg, 1990.
- * Pub. by IEEE Computer Society Press, Los Alamitos, CA. ISBN 0-8186-8944-7.
- *
- * The downsampling algorithm used here is a simple average of the source
- * pixels covered by the output pixel. The hi-falutin sampling literature
- * refers to this as a "box filter". In general the characteristics of a box
- * filter are not very good, but for the specific cases we normally use (1:1
- * and 2:1 ratios) the box is equivalent to a "triangle filter" which is not
- * nearly so bad. If you intend to use other sampling ratios, you'd be well
- * advised to improve this code.
- *
- * A simple input-smoothing capability is provided. This is mainly intended
- * for cleaning up color-dithered GIF input files (if you find it inadequate,
- * we suggest using an external filtering program such as pnmconvol). When
- * enabled, each input pixel P is replaced by a weighted sum of itself and its
- * eight neighbors. P's weight is 1-8*SF and each neighbor's weight is SF,
- * where SF = (smoothing_factor / 1024).
- * Currently, smoothing is only supported for 2h2v sampling factors.

- * number of scanlines it has read, if any). The application should resume
- * decompression after it has loaded more data into the input buffer. Note
- * that there are substantial restrictions on the use of suspension --- see
- * the documentation.
- *
- * When suspending, the decompressor will back up to a convenient restart point
- * (typically the start of the current MCU). next_input_byte & bytes_in_buffer
- * indicate where the restart point will be if the current call returns FALSE.

- * YCbCr is defined per Recommendation ITU-R BT.601-7 (03/2011),
- * previously known as Recommendation CCIR 601-1, except that Cb and Cr
- * are normalized to the range 0..MAXJSAMPLE rather than -0.5 .. 0.5.
- * sRGB (standard RGB color space) is defined per IEC 61966-2-1:1999.
- * sYCC (standard luma-chroma-chroma color space with extended gamut)
- * is defined per IEC 61966-2-1:1999 Amendment A1:2003 Annex F.
- * bg-sRGB and bg-sYCC (big gamut standard color spaces)
- * are defined per IEC 61966-2-1:1999 Amendment A1:2003 Annex G.
- * Note that the derived conversion coefficients given in some of these
- * documents are imprecise. The general conversion equations are
- *
- * R = Y + K * (1 - Kr) * Cr
- * G = Y - K * (Kb * (1 - Kb) * Cb + Kr * (1 - Kr) * Cr) / (1 - Kr - Kb)
- * B = Y + K * (1 - Kb) * Cb
- *
- * Y = Kr * R + (1 - Kr - Kb) * G + Kb * B
- *
- * With Kr = 0.299 and Kb = 0.114 (derived according to SMPTE RP 177-1993
- * from the 1953 FCC NTSC primaries and CIE Illuminant C), K = 2 for sYCC,
- * the conversion equations to be implemented are therefore
- *
- * R = Y + 1.402 * Cr
- * G = Y - 0.344136286 * Cb - 0.714136286 * Cr
- * B = Y + 1.772 * Cb
- *
- * Y = 0.299 * R + 0.587 * G + 0.114 * B
- *
- * where Cb and Cr represent the incoming values less CENTERJSAMPLE.
- * For bg-sYCC, with K = 4, the equations are
- *
- * R = Y + 2.804 * Cr
- * G = Y - 0.688272572 * Cb - 1.428272572 * Cr
- * B = Y + 3.544 * Cb
- *
- * To avoid floating-point arithmetic, we represent the fractional constants
- * as integers scaled up by 2^16 (about 4 digits precision); we have to divide
- * the products by 2^16, with appropriate rounding, to get the correct answer.
- * Notice that Y, being an integral input, does not contribute any fraction
- * so it need not participate in the rounding.
- *
- * For even more speed, we avoid doing any multiplications in the inner loop
- * by precalculating the constants times Cb and Cr for all possible values.
- * For 8-bit JSAMPLEs this is very reasonable (only 256 entries per table);
- * for 9-bit to 12-bit samples it is still acceptable. It's not very
- * reasonable for 16-bit samples, but if you want lossless storage you
- * shouldn't be changing colorspace anyway.
- * The Cr=>R and Cb=>B values can be rounded to integers in advance; the
- * values for the G calculation are left scaled up, since we must add them
- * together before rounding.

-/*
- * In the current system design, the main buffer need never be a full-image
- * buffer; any full-height buffers will be found inside the coefficient or
- * postprocessing controllers. Nonetheless, the main controller is not
- * trivial. Its responsibility is to provide context rows for upsampling/
- * rescaling, and doing this in an efficient fashion is a bit tricky.
- *
- * Postprocessor input data is counted in "row groups". A row group
- * is defined to be (v_samp_factor * DCT_scaled_size / min_DCT_scaled_size)
- * sample rows of each component. (We require DCT_scaled_size values to be
- * chosen such that these numbers are integers. In practice DCT_scaled_size
- * values will likely be powers of two, so we actually have the stronger
- * condition that DCT_scaled_size / min_DCT_scaled_size is an integer.)
- * Upsampling will typically produce max_v_samp_factor pixel rows from each
- * row group (times any additional scale factor that the upsampler is
- * applying).
- *
- * The coefficient controller will deliver data to us one iMCU row at a time;
- * each iMCU row contains v_samp_factor * DCT_scaled_size sample rows, or
- * exactly min_DCT_scaled_size row groups. (This amount of data corresponds
- * to one row of MCUs when the image is fully interleaved.) Note that the
- * number of sample rows varies across components, but the number of row
- * groups does not. Some garbage sample rows may be included in the last iMCU
- * row at the bottom of the image.
- *
- * Depending on the vertical scaling algorithm used, the upsampler may need
- * access to the sample row(s) above and below its current input row group.
- * The upsampler is required to set need_context_rows TRUE at global selection
- * time if so. When need_context_rows is FALSE, this controller can simply
- * obtain one iMCU row at a time from the coefficient controller and dole it
- * out as row groups to the postprocessor.
- *
- * When need_context_rows is TRUE, this controller guarantees that the buffer
- * passed to postprocessing contains at least one row group's worth of samples
- * above and below the row group(s) being processed. Note that the context
- * rows "above" the first passed row group appear at negative row offsets in
- * the passed buffer. At the top and bottom of the image, the required
- * context rows are manufactured by duplicating the first or last real sample
- * row; this avoids having special cases in the upsampling inner loops.
- *
- * The amount of context is fixed at one row group just because that's a
- * convenient number for this controller to work with. The existing
- * upsamplers really only need one sample row of context. An upsampler
- * supporting arbitrary output rescaling might wish for more than one row
- * group of context when shrinking the image; tough, we don't handle that.
- * (This is justified by the assumption that downsizing will be handled mostly
- * by adjusting the DCT_scaled_size values, so that the actual scale factor at
- * the upsample step needn't be much less than one.)
- *
- * To provide the desired context, we have to retain the last two row groups
- * of one iMCU row while reading in the next iMCU row. (The last row group
- * can't be processed until we have another row group for its below-context,
- * and so we have to save the next-to-last group too for its above-context.)
- * We could do this most simply by copying data around in our buffer, but
- * that'd be very slow. We can avoid copying any data by creating a rather
- * strange pointer structure. Here's how it works. We allocate a workspace
- * consisting of M+2 row groups (where M = min_DCT_scaled_size is the number
- * of row groups per iMCU row). We create two sets of redundant pointers to
- * the workspace. Labeling the physical row groups 0 to M+1, the synthesized
- * pointer lists look like this:
- * M+1 M-1
- * master pointer --> 0 master pointer --> 0
- * 1 1
- * ... ...
- * M-3 M-3
- * M-2 M
- * M-1 M+1
- * M M-2
- * M+1 M-1
- * 0 0
- * We read alternate iMCU rows using each master pointer; thus the last two
- * row groups of the previous iMCU row remain un-overwritten in the workspace.
- * The pointer lists are set up so that the required context rows appear to
- * be adjacent to the proper places when we pass the pointer lists to the
- * upsampler.
- *
- * The above pictures describe the normal state of the pointer lists.
- * At top and bottom of the image, we diddle the pointer lists to duplicate
- * the first or last sample row as necessary (this is cheaper than copying
- * sample rows around).
- *

- *
- * read_restart_marker calls resync_to_restart if it finds a marker other than

- * a nonzero restart interval has been declared.) cinfo->unread_marker is
- * the marker code actually found (might be anything, except 0 or FF).
- * The desired restart marker number (0..7) is passed as a parameter.

- * the current data-source input point; usually it should be reset to zero
- * before returning.

- * This implementation is substantially constrained by wanting to treat the

- * 1. Simply discard the marker and let the entropy decoder resume at next
- * byte of file.
- * 2. Read forward until we find another marker, discarding intervening
- * data. (In theory we could look ahead within the current bufferload,
- * without having to discard data if we don't find the desired marker.
- * This idea is not implemented here, in part because it makes behavior
- * dependent on buffer size and chance buffer-boundary positions.)
- * 3. Leave the marker unread (by failing to zero cinfo->unread_marker).
- * This will cause the entropy decoder to process an empty data segment,
- * inserting dummy zeroes, and then we will reprocess the marker.
- *
- * #2 is appropriate if we think the desired marker lies ahead, while #3 is
- * appropriate if the found marker is a future restart marker (indicating
- * that we have missed the desired restart marker, probably because it got
- * corrupted).
- * We apply #2 or #3 if the found marker is a restart marker no more than
- * two counts behind or ahead of the expected one. We also apply #2 if the
- * found marker is not a legal JPEG marker code (it's certainly bogus data).
- * If the found marker is a restart marker more than 2 counts away, we do #1
- * (too much risk that the marker is erroneous; with luck we will be able to
- * resync at some future point).
- * For any valid non-restart JPEG marker, we apply #3. This keeps us from
- * overrunning the end of a scan. An implementation limited to single-scan
- * files might find it better to apply #2 for markers other than EOI, since
- * any other marker would have to be bogus data in that case.

- * Several decompression processes need to range-limit values to the range

- * samples. Under normal circumstances this is more than enough range and
- * a correct output will be generated; with bogus input data the mask will
- * cause wraparound, and we will safely generate a bogus-but-in-range output.
- * For the post-IDCT step, we want to convert the data from signed to unsigned
- * representation by adding CENTERJSAMPLE at the same time that we limit it.
- * This is accomplished with SUBSET = CENTER - CENTERJSAMPLE.

- * Copyright (C) 1994-1996, Thomas G. Lane.
- * Modified 2013-2015 by Guido Vollbeding.
- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains code for merged upsampling/color conversion.
- *
- * This file combines functions from jdsample.c and jdcolor.c;
- * read those files first to understand what's going on.
- *
- * When the chroma components are to be upsampled by simple replication
- * (ie, box filtering), we can save some work in color conversion by
- * calculating all the output pixels corresponding to a pair of chroma
- * samples at one time. In the conversion equations
- * R = Y + K1 * Cr
- * G = Y + K2 * Cb + K3 * Cr
- * B = Y + K4 * Cb
- * only the Y term varies among the group of pixels corresponding to a pair
- * of chroma samples, so the rest of the terms can be calculated just once.
- * At typical sampling ratios, this eliminates half or three-quarters of the
- * multiplications needed for color conversion.
- *
- * This file currently provides implementations for the following cases:
- * YCC => RGB color conversion only (YCbCr or BG_YCC).
- * Sampling ratios of 2h1v or 2h2v.
- * No scaling needed at upsample time.
- * Corner-aligned (non-CCIR601) sampling alignment.
- * Other special cases could be added, but in most applications these are
- * the only common cases. (For uncommon cases we fall back on the more
- * general code in jdsample.c and jdcolor.c.)

- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains a floating-point implementation of the
- * forward DCT (Discrete Cosine Transform).
- *
- * This implementation should be more accurate than either of the integer
- * DCT implementations. However, it may not give the same results on all
- * machines because of differences in roundoff behavior. Speed will depend
- * on the hardware's floating point capacity.
- *
- * A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT
- * on each column. Direct algorithms are also available, but they are
- * much more complex and seem not to be any faster when reduced to code.
- *
- * This implementation is based on Arai, Agui, and Nakajima's algorithm for
- * scaled DCT. Their original paper (Trans. IEICE E-71(11):1095) is in
- * Japanese, but the algorithm is described in the Pennebaker & Mitchell
- * JPEG textbook (see REFERENCES section in file README). The following code
- * is based directly on figure 4-8 in P&M.
- * While an 8-point DCT cannot be done in less than 11 multiplies, it is
- * possible to arrange the computation so that many of the multiplies are
- * simple scalings of the final outputs. These multiplies can then be
- * folded into the multiplications or divisions by the JPEG quantization
- * table entries. The AA&N method leaves only 5 multiplies and 29 adds
- * to be done in the DCT itself.
- * The primary disadvantage of this method is that with a fixed-point
- * implementation, accuracy is lost due to imprecise representation of the
- * scaled quantization values. However, that problem does not arise if
- * we use floating point arithmetic.

- * This file contains a fast, not so accurate integer implementation of the

- *
- * A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT
- * on each column. Direct algorithms are also available, but they are
- * much more complex and seem not to be any faster when reduced to code.
- *
- * This implementation is based on Arai, Agui, and Nakajima's algorithm for
- * scaled DCT. Their original paper (Trans. IEICE E-71(11):1095) is in
- * Japanese, but the algorithm is described in the Pennebaker & Mitchell
- * JPEG textbook (see REFERENCES section in file README). The following code
- * is based directly on figure 4-8 in P&M.
- * While an 8-point DCT cannot be done in less than 11 multiplies, it is
- * possible to arrange the computation so that many of the multiplies are
- * simple scalings of the final outputs. These multiplies can then be
- * folded into the multiplications or divisions by the JPEG quantization
- * table entries. The AA&N method leaves only 5 multiplies and 29 adds
- * to be done in the DCT itself.
- * The primary disadvantage of this method is that with fixed-point math,
- * accuracy is lost due to imprecise representation of the scaled
- * quantization values. The smaller the quantization table entry, the less
- * precise the scaled value, so this implementation does worse with high-
- * quality-setting files than with low-quality ones.

- * A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT
- * on each column. Direct algorithms are also available, but they are
- * much more complex and seem not to be any faster when reduced to code.
- *
- * This implementation is based on an algorithm described in
- * C. Loeffler, A. Ligtenberg and G. Moschytz, "Practical Fast 1-D DCT
- * Algorithms with 11 Multiplications", Proc. Int'l. Conf. on Acoustics,
- * Speech, and Signal Processing 1989 (ICASSP '89), pp. 988-991.
- * The primary algorithm described there uses 11 multiplies and 29 adds.
- * We use their alternate method with 12 multiplies and 32 adds.
- * The advantage of this method is that no data path contains more than one
- * multiplication; this allows a very simple and accurate implementation in
- * scaled fixed-point arithmetic, with a minimal number of shifts.
- *
- * We also provide FDCT routines with various input sample block sizes for
- * direct resolution reduction or enlargement and for direct resolving the
- * common 2x1 and 1x2 subsampling cases without additional resampling: NxN
- * (N=1...16), 2NxN, and Nx2N (N=1...8) pixels for one 8x8 output DCT block.
- *
- * For N<8 we fill the remaining block coefficients with zero.
- * For N>8 we apply a partial N-point FDCT on the input samples, computing
- * just the lower 8 frequency coefficients and discarding the rest.
- *
- * We must scale the output coefficients of the N-point FDCT appropriately
- * to the standard 8-point FDCT level by 8/N per 1-D pass. This scaling
- * is folded into the constant multipliers (pass 2) and/or final/initial
- * shifting.
- *
- * CAUTION: We rely on the FIX() macro except for the N=1,2,4,8 cases
- * since there would be too many additional constants to pre-calculate.

- * The poop on this scaling stuff is as follows:
- *
- * Each 1-D DCT step produces outputs which are a factor of sqrt(N)
- * larger than the true DCT outputs. The final outputs are therefore
- * a factor of N larger than desired; since N=8 this can be cured by
- * a simple right shift at the end of the algorithm. The advantage of
- * this arrangement is that we save two multiplications per 1-D DCT,
- * because the y0 and y4 outputs need not be divided by sqrt(N).
- * In the IJG code, this factor of 8 is removed by the quantization step
- * (in jcdctmgr.c), NOT in this module.
- *
- * We have to do addition and subtraction of the integer inputs, which
- * is no problem, and multiplication by fractional constants, which is
- * a problem to do in integer arithmetic. We multiply all the constants
- * by CONST_SCALE and convert them to integer constants (thus retaining
- * CONST_BITS bits of precision in the constants). After doing a
- * multiplication we have to divide the product by CONST_SCALE, with proper
- * rounding, to produce the correct output. This division can be done
- * cheaply as a right shift of CONST_BITS bits. We postpone shifting
- * as long as possible so that partial sums can be added together with
- * full fractional precision.
- *
- * The outputs of the first pass are scaled up by PASS1_BITS bits so that
- * they are represented to better-than-integral precision. These outputs
- * require BITS_IN_JSAMPLE + PASS1_BITS + 3 bits; this fits in a 16-bit word
- * with the recommended scaling. (For 12-bit sample data, the intermediate
- * array is INT32 anyway.)

- * Copyright (C) 1994-1998, Thomas G. Lane.

- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains a floating-point implementation of the
- * inverse DCT (Discrete Cosine Transform). In the IJG code, this routine
- * must also perform dequantization of the input coefficients.
- *
- * This implementation should be more accurate than either of the integer
- * IDCT implementations. However, it may not give the same results on all
- * machines because of differences in roundoff behavior. Speed will depend
- * on the hardware's floating point capacity.
- *
- * A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT
- * on each row (or vice versa, but it's more convenient to emit a row at
- * a time). Direct algorithms are also available, but they are much more
- * complex and seem not to be any faster when reduced to code.
- *
- * This implementation is based on Arai, Agui, and Nakajima's algorithm for
- * scaled DCT. Their original paper (Trans. IEICE E-71(11):1095) is in
- * Japanese, but the algorithm is described in the Pennebaker & Mitchell
- * JPEG textbook (see REFERENCES section in file README). The following code
- * is based directly on figure 4-8 in P&M.
- * While an 8-point DCT cannot be done in less than 11 multiplies, it is
- * possible to arrange the computation so that many of the multiplies are
- * simple scalings of the final outputs. These multiplies can then be
- * folded into the multiplications or divisions by the JPEG quantization
- * table entries. The AA&N method leaves only 5 multiplies and 29 adds
- * to be done in the DCT itself.
- * The primary disadvantage of this method is that with a fixed-point
- * implementation, accuracy is lost due to imprecise representation of the
- * scaled quantization values. However, that problem does not arise if
- * we use floating point arithmetic.

- * jidctint.c
- *
- * Copyright (C) 1991-1998, Thomas G. Lane.
- * Modification developed 2002-2015 by Guido Vollbeding.
- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains a slow-but-accurate integer implementation of the
- * inverse DCT (Discrete Cosine Transform). In the IJG code, this routine
- * must also perform dequantization of the input coefficients.
- *
- * A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT
- * on each row (or vice versa, but it's more convenient to emit a row at
- * a time). Direct algorithms are also available, but they are much more
- * complex and seem not to be any faster when reduced to code.
- *
- * This implementation is based on an algorithm described in
- * C. Loeffler, A. Ligtenberg and G. Moschytz, "Practical Fast 1-D DCT
- * Algorithms with 11 Multiplications", Proc. Int'l. Conf. on Acoustics,
- * Speech, and Signal Processing 1989 (ICASSP '89), pp. 988-991.
- * The primary algorithm described there uses 11 multiplies and 29 adds.
- * We use their alternate method with 12 multiplies and 32 adds.
- * The advantage of this method is that no data path contains more than one
- * multiplication; this allows a very simple and accurate implementation in
- * scaled fixed-point arithmetic, with a minimal number of shifts.
- *
- * We also provide IDCT routines with various output sample block sizes for
- * direct resolution reduction or enlargement and for direct resolving the
- * common 2x1 and 1x2 subsampling cases without additional resampling: NxN
- * (N=1...16), 2NxN, and Nx2N (N=1...8) pixels for one 8x8 input DCT block.
- *
- * For N<8 we simply take the corresponding low-frequency coefficients of
- * the 8x8 input DCT block and apply an NxN point IDCT on the sub-block
- * to yield the downscaled outputs.
- * This can be seen as direct low-pass downsampling from the DCT domain
- * point of view rather than the usual spatial domain point of view,
- * yielding significant computational savings and results at least
- * as good as common bilinear (averaging) spatial downsampling.
- *
- * For N>8 we apply a partial NxN IDCT on the 8 input coefficients as
- * lower frequencies and higher frequencies assumed to be zero.
- * It turns out that the computational effort is similar to the 8x8 IDCT
- * regarding the output size.
- * Furthermore, the scaling and descaling is the same for all IDCT sizes.
- *
- * CAUTION: We rely on the FIX() macro except for the N=1,2,4,8 cases
- * since there would be too many additional constants to pre-calculate.

- * The poop on this scaling stuff is as follows:
- *
- * Each 1-D IDCT step produces outputs which are a factor of sqrt(N)
- * larger than the true IDCT outputs. The final outputs are therefore
- * a factor of N larger than desired; since N=8 this can be cured by
- * a simple right shift at the end of the algorithm. The advantage of
- * this arrangement is that we save two multiplications per 1-D IDCT,
- * because the y0 and y4 inputs need not be divided by sqrt(N).
- *
- * We have to do addition and subtraction of the integer inputs, which
- * is no problem, and multiplication by fractional constants, which is
- * a problem to do in integer arithmetic. We multiply all the constants
- * by CONST_SCALE and convert them to integer constants (thus retaining
- * CONST_BITS bits of precision in the constants). After doing a
- * multiplication we have to divide the product by CONST_SCALE, with proper
- * rounding, to produce the correct output. This division can be done
- * cheaply as a right shift of CONST_BITS bits. We postpone shifting
- * as long as possible so that partial sums can be added together with
- * full fractional precision.
- *
- * The outputs of the first pass are scaled up by PASS1_BITS bits so that
- * they are represented to better-than-integral precision. These outputs
- * require BITS_IN_JSAMPLE + PASS1_BITS + 3 bits; this fits in a 16-bit word
- * with the recommended scaling. (To scale up 12-bit sample data further, an
- * intermediate INT32 array would be needed.)
- *
- * To avoid overflow of the 32-bit intermediate results in pass 2, we must
- * have BITS_IN_JSAMPLE + CONST_BITS + PASS1_BITS <= 26. Error analysis
- * shows that the values given below are the most effective.

- *
- * Copyright (C) 1992-1997, Thomas G. Lane.
- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * jmemmac.c provides an Apple Macintosh implementation of the system-
- * dependent portion of the JPEG memory manager.
- *
- * If you use jmemmac.c, then you must define USE_MAC_MEMMGR in the
- * JPEG_INTERNALS part of jconfig.h.
- *
- * jmemmac.c uses the Macintosh toolbox routines NewPtr and DisposePtr
- * instead of malloc and free. It accurately determines the amount of
- * memory available by using CompactMem. Notice that if left to its
- * own devices, this code can chew up all available space in the
- * application's zone, with the exception of the rather small "slop"
- * factor computed in jpeg_mem_available(). The application can ensure
- * that more space is left over by reducing max_memory_to_use.
- *
- * Large images are swapped to disk using temporary files and System 7.0+'s
- * temporary folder functionality.
- *
- * Note that jmemmac.c depends on two features of MacOS that were first
- * introduced in System 7: FindFolder and the FSSpec-based calls.
- * If your application uses jmemmac.c and is run under System 6 or earlier,
- * and the jpeg library decides it needs a temporary file, it will abort,
- * printing error messages about requiring System 7. (If no temporary files
- * are created, it will run fine.)
- *
- * If you want to use jmemmac.c in an application that might be used with
- * System 6 or earlier, then you should remove dependencies on FindFolder
- * and the FSSpec calls. You will need to replace FindFolder with some
- * other mechanism for finding a place to put temporary files, and you
- * should replace the FSSpec calls with their HFS equivalents:
- *
- * FSpDelete -> HDelete
- * FSpGetFInfo -> HGetFInfo
- * FSpCreate -> HCreate
- * FSpOpenDF -> HOpen *** Note: not HOpenDF ***
- * FSMakeFSSpec -> (fill in spec by hand.)
- *
- * (Use HOpen instead of HOpenDF. HOpen is just a glue-interface to PBHOpen,
- * which is on all HFS macs. HOpenDF is a System 7 addition which avoids the
- * ages-old problem of names starting with a period.)
- *
- * Contributed by Sam Bushell (jsam@iagu.on.net) and
- * Dan Gildor (gyld@in-touch.com).

- *
- * This file contains the JPEG system-independent memory management
- * routines. This code is usable across a wide variety of machines; most
- * of the system dependencies have been isolated in a separate file.
- * The major functions provided here are:
- * * pool-based allocation and freeing of memory;
- * * policy decisions about how to divide available memory among the
- * virtual arrays;
- * * control logic for swapping virtual arrays between main memory and
- * backing storage.
- * The separate system-dependent file provides the actual backing-storage
- * access code, and it contains the policy decision about how much total
- * main memory to use.
- * This file is system-dependent in the sense that some of its functions
- * are unnecessary in some systems. For example, if there is enough virtual
- * memory so that backing storage will never be used, much of the virtual
- * array control logic could be removed. (Of course, if you have that much
- * memory then you shouldn't care about a little bit of unused code...)

- * Some important notes:

- * It's not a good idea to try to merge the sarray and barray routines,
- * even though they are textually almost the same, because samples are

- * Many machines require storage alignment: longs must start on 4-byte
- * boundaries, doubles on 8-byte boundaries, etc. On such machines, malloc()
- * always returns pointers that are multiples of the worst-case alignment
- * requirement, and we had better do so too.
- * There isn't any really portable way to determine the worst-case alignment
- * requirement. This module assumes that the alignment requirement is
- * multiples of sizeof(ALIGN_TYPE).
- * By default, we define ALIGN_TYPE as double. This is necessary on some
- * workstations (where doubles really do need 8-byte alignment) and will work
- * fine on nearly everything. If your machine has lesser alignment needs,
- * you can save a few bytes by making ALIGN_TYPE smaller.
- * The only place I know of where this will NOT work is certain Macintosh
- * 680x0 compilers that define double as a 10-byte IEEE extended float.
- * Doing 10-byte alignment is counterproductive because longwords won't be
- * aligned well. Put "#define ALIGN_TYPE long" in jconfig.h if you have
- * such a compiler.

- * About virtual array management:
- *
- * The above "normal" array routines are only used to allocate strip buffers
- * (as wide as the image, but just a few rows high). Full-image-sized buffers
- * are handled as "virtual" arrays. The array is still accessed a strip at a
- * time, but the memory manager must save the whole array for repeated
- * accesses. The intended implementation is that there is a strip buffer in
- * memory (as high as is possible given the desired memory limit), plus a
- * backing file that holds the rest of the array.
- *
- * The request_virt_array routines are told the total size of the image and
- * the maximum number of rows that will be accessed at once. The in-memory
- * buffer must be at least as large as the maxaccess value.
- *
- * The request routines create control blocks but not the in-memory buffers.
- * That is postponed until realize_virt_arrays is called. At that time the
- * total amount of space needed is known (approximately, anyway), so free
- * memory can be divided up fairly.
- *
- * The access_virt_array routines are responsible for making a specific strip
- * area accessible (after reading or writing the backing file, if necessary).
- * Note that the access routines are told whether the caller intends to modify
- * the accessed strip; during a read-only pass this saves having to rewrite
- * data to disk. The access routines are also responsible for pre-zeroing
- * any newly accessed rows, if pre-zeroing was requested.
- *
- * In current usage, the access requests are usually for nonoverlapping
- * strips; that is, successive access start_row numbers differ by exactly
- * num_rows = maxaccess. This means we can get good performance with simple
- * buffer dump/reload logic, by making the in-memory buffer be a multiple
- * of the access height; then there will never be accesses across bufferload
- * boundaries. The code will still work with overlapping access requests,
- * but it doesn't handle bufferload overlaps very efficiently.

- * Selection of a file name for a temporary file.
- * This is system-dependent!
- *
- * The code as given is suitable for most Unix systems, and it is easily
- * modified for most non-Unix systems. Some notes:
- * 1. The temp file is created in the directory named by TEMP_DIRECTORY.
- * The default value is /usr/tmp, which is the conventional place for
- * creating large temp files on Unix. On other systems you'll probably
- * want to change the file location. You can do this by editing the
- * #define, or (preferred) by defining TEMP_DIRECTORY in jconfig.h.
- *
- * 2. If you need to change the file name as well as its location,
- * you can override the TEMP_FILE_NAME macro. (Note that this is
- * actually a printf format string; it must contain %s and %d.)
- * Few people should need to do this.
- *
- * 3. mktemp() is used to ensure that multiple processes running
- * simultaneously won't select the same file names. If your system
- * doesn't have mktemp(), define NO_MKTEMP to do it the hard way.
- * (If you don't have , also define NO_ERRNO_H.)
- *
- * 4. You probably want to define NEED_SIGNAL_CATCHER so that cjpeg.c/djpeg.c
- * will cause the temp files to be removed if you stop the program early.

-.TH JPEGTRAN 1 "20 September 2015"
-.SH NAME
-jpegtran \- lossless transformation of JPEG files
-.SH SYNOPSIS
-.B jpegtran
-[
-.I options
-]
-[
-.I filename
-]
-.LP
-.SH DESCRIPTION
-.LP
-.B jpegtran
-performs various useful transformations of JPEG files.
-It can translate the coded representation from one variant of JPEG to another,
-for example from baseline JPEG to progressive JPEG or vice versa. It can also
-perform some rearrangements of the image data, for example turning an image
-from landscape to portrait format by rotation.
-.PP
-For EXIF files and JPEG files containing Exif data, you may prefer to use
-.B exiftran
-instead.
-.PP
-.B jpegtran
-works by rearranging the compressed data (DCT coefficients), without
-ever fully decoding the image. Therefore, its transformations are lossless:
-there is no image degradation at all, which would not be true if you used
-.B djpeg
-followed by
-.B cjpeg
-to accomplish the same conversion. But by the same token,
-.B jpegtran
-cannot perform lossy operations such as changing the image quality. However,
-while the image data is losslessly transformed, metadata can be removed. See
-the
-.B \-copy
-option for specifics.
-.PP
-.B jpegtran
-reads the named JPEG/JFIF file, or the standard input if no file is
-named, and produces a JPEG/JFIF file on the standard output.
-.SH OPTIONS
-All switch names may be abbreviated; for example,
-.B \-optimize
-may be written
-.B \-opt
-or
-.BR \-o .
-Upper and lower case are equivalent.
-British spellings are also accepted (e.g.,
-.BR \-optimise ),
-though for brevity these are not mentioned below.
-.PP
-To specify the coded JPEG representation used in the output file,
-.B jpegtran
-accepts a subset of the switches recognized by
-.BR cjpeg :
-.TP
-.B \-optimize
-Perform optimization of entropy encoding parameters.
-.TP
-.B \-progressive
-Create progressive JPEG file.
-.TP
-.BI \-restart " N"
-Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is
-attached to the number.
-.TP
-.B \-arithmetic
-Use arithmetic coding.
-.TP
-.BI \-scans " file"
-Use the scan script given in the specified text file.
-.PP
-See
-.BR cjpeg (1)
-for more details about these switches.
-If you specify none of these switches, you get a plain baseline-JPEG output
-file. The quality setting and so forth are determined by the input file.
-.PP
-The image can be losslessly transformed by giving one of these switches:
-.TP
-.B \-flip horizontal
-Mirror image horizontally (left-right).
-.TP
-.B \-flip vertical
-Mirror image vertically (top-bottom).
-.TP
-.B \-rotate 90
-Rotate image 90 degrees clockwise.
-.TP
-.B \-rotate 180
-Rotate image 180 degrees.
-.TP
-.B \-rotate 270
-Rotate image 270 degrees clockwise (or 90 ccw).
-.TP
-.B \-transpose
-Transpose image (across UL-to-LR axis).
-.TP
-.B \-transverse
-Transverse transpose (across UR-to-LL axis).
-.IP
-The transpose transformation has no restrictions regarding image dimensions.
-The other transformations operate rather oddly if the image dimensions are not
-a multiple of the iMCU size (usually 8 or 16 pixels), because they can only
-transform complete blocks of DCT coefficient data in the desired way.
-.IP
-.BR jpegtran 's
-default behavior when transforming an odd-size image is designed
-to preserve exact reversibility and mathematical consistency of the
-transformation set. As stated, transpose is able to flip the entire image
-area. Horizontal mirroring leaves any partial iMCU column at the right edge
-untouched, but is able to flip all rows of the image. Similarly, vertical
-mirroring leaves any partial iMCU row at the bottom edge untouched, but is
-able to flip all columns. The other transforms can be built up as sequences
-of transpose and flip operations; for consistency, their actions on edge
-pixels are defined to be the same as the end result of the corresponding
-transpose-and-flip sequence.
-.IP
-For practical use, you may prefer to discard any untransformable edge pixels
-rather than having a strange-looking strip along the right and/or bottom edges
-of a transformed image. To do this, add the
-.B \-trim
-switch:
-.TP
-.B \-trim
-Drop non-transformable edge blocks.
-.IP
-Obviously, a transformation with
-.B \-trim
-is not reversible, so strictly speaking
-.B jpegtran
-with this switch is not lossless. Also, the expected mathematical
-equivalences between the transformations no longer hold. For example,
-.B \-rot 270 -trim
-trims only the bottom edge, but
-.B \-rot 90 -trim
-followed by
-.B \-rot 180 -trim
-trims both edges.
-.IP
-If you are only interested in perfect transformation, add the
-.B \-perfect
-switch:
-.TP
-.B \-perfect
-Fails with an error if the transformation is not perfect.
-.IP
-For example you may want to do
-.IP
-.B (jpegtran \-rot 90 -perfect
-.I foo.jpg
-.B || djpeg
-.I foo.jpg
-.B | pnmflip \-r90 | cjpeg)
-.IP
-to do a perfect rotation if available or an approximated one if not.
-.PP
-We also offer a lossless-crop option, which discards data outside a given
-image region but losslessly preserves what is inside. Like the rotate and
-flip transforms, lossless crop is restricted by the current JPEG format: the
-upper left corner of the selected region must fall on an iMCU boundary. If
-this does not hold for the given crop parameters, we silently move the upper
-left corner up and/or left to make it so, simultaneously increasing the
-region dimensions to keep the lower right crop corner unchanged. (Thus, the
-output image covers at least the requested region, but may cover more.)
-The adjustment of the region dimensions may be optionally disabled by
-attaching an 'f' character ("force") to the width or height number.
-
-The image can be losslessly cropped by giving the switch:
-.TP
-.B \-crop WxH+X+Y
-Crop to a rectangular subarea of width W, height H starting at point X,Y.
-.PP
-A complementary lossless-wipe option is provided to discard (gray out) data
-inside a given image region while losslessly preserving what is outside:
-.TP
-.B \-wipe WxH+X+Y
-Wipe (gray out) a rectangular subarea of width W, height H starting at point
-X,Y.
-.PP
-Other not-strictly-lossless transformation switches are:
-.TP
-.B \-grayscale
-Force grayscale output.
-.IP
-This option discards the chrominance channels if the input image is YCbCr
-(ie, a standard color JPEG), resulting in a grayscale JPEG file. The
-luminance channel is preserved exactly, so this is a better method of reducing
-to grayscale than decompression, conversion, and recompression. This switch
-is particularly handy for fixing a monochrome picture that was mistakenly
-encoded as a color JPEG. (In such a case, the space savings from getting rid
-of the near-empty chroma channels won't be large; but the decoding time for
-a grayscale JPEG is substantially less than that for a color JPEG.)
-.TP
-.BI \-scale " M/N"
-Scale the output image by a factor M/N.
-.IP
-Currently supported scale factors are M/N with all M from 1 to 16, where N is
-the source DCT size, which is 8 for baseline JPEG. If the /N part is omitted,
-then M specifies the DCT scaled size to be applied on the given input. For
-baseline JPEG this is equivalent to M/8 scaling, since the source DCT size
-for baseline JPEG is 8.
-.B Caution:
-An implementation of the JPEG SmartScale extension is required for this
-feature. SmartScale enabled JPEG is not yet widely implemented, so many
-decoders will be unable to view a SmartScale extended JPEG file at all.
-.PP
-.B jpegtran
-also recognizes these switches that control what to do with "extra" markers,
-such as comment blocks:
-.TP
-.B \-copy none
-Copy no extra markers from source file. This setting suppresses all
-comments and other metadata in the source file.
-.TP
-.B \-copy comments
-Copy only comment markers. This setting copies comments from the source file,
-but discards any other metadata.
-.TP
-.B \-copy all
-Copy all extra markers. This setting preserves metadata
-found in the source file, such as JFIF thumbnails, Exif data, and Photoshop
-settings. In some files these extra markers can be sizable. Note that this
-option will copy thumbnails as-is; they will not be transformed.
-.IP
-The default behavior is
-.BR "\-copy comments" .
-(Note: in IJG releases v6 and v6a,
-.B jpegtran
-always did the equivalent of
-.BR "\-copy none" .)
-.PP
-Additional switches recognized by jpegtran are:
-.TP
-.BI \-maxmemory " N"
-Set limit for amount of memory to use in processing large images. Value is
-in thousands of bytes, or millions of bytes if "M" is attached to the
-number. For example,
-.B \-max 4m
-selects 4000000 bytes. If more space is needed, temporary files will be used.
-.TP
-.BI \-outfile " name"
-Send output image to the named file, not to standard output.
-.TP
-.B \-verbose
-Enable debug printout. More
-.BR \-v 's
-give more output. Also, version information is printed at startup.
-.TP
-.B \-debug
-Same as
-.BR \-verbose .
-.SH EXAMPLES
-.LP
-This example converts a baseline JPEG file to progressive form:
-.IP
-.B jpegtran \-progressive
-.I foo.jpg
-.B >
-.I fooprog.jpg
-.PP
-This example rotates an image 90 degrees clockwise, discarding any
-unrotatable edge pixels:
-.IP
-.B jpegtran \-rot 90 -trim
-.I foo.jpg
-.B >
-.I foo90.jpg
-.SH ENVIRONMENT
-.TP
-.B JPEGMEM
-If this environment variable is set, its value is the default memory limit.
-The value is specified as described for the
-.B \-maxmemory
-switch.
-.B JPEGMEM
-overrides the default value specified when the program was compiled, and
-itself is overridden by an explicit
-.BR \-maxmemory .

-.SH AUTHOR
-Independent JPEG Group
-.SH BUGS
-The transform options can't transform odd-size images perfectly. Use
-.B \-trim
-or
-.B \-perfect
-if you don't like the results.
-.PP
-The entire image is read into memory and then written out again, even in
-cases where this isn't really necessary. Expect swapping on large images,
-especially when using the more complex transform options.

-/*
- * The main purpose of 1-pass quantization is to provide a fast, if not very
- * high quality, colormapped output capability. A 2-pass quantizer usually
- * gives better visual quality; however, for quantized grayscale output this
- * quantizer is perfectly adequate. Dithering is highly recommended with this
- * quantizer, though you can turn it off if you really want to.
- *
- * In 1-pass quantization the colormap must be chosen in advance of seeing the
- * image. We use a map consisting of all combinations of Ncolors[i] color
- * values for the i'th component. The Ncolors[] values are chosen so that
- * their product, the total number of colors, is no more than that requested.
- * (In most cases, the product will be somewhat less.)
- *
- * Since the colormap is orthogonal, the representative value for each color
- * component can be determined without considering the other components;
- * then these indexes can be combined into a colormap index by a standard
- * N-dimensional-array-subscript calculation. Most of the arithmetic involved
- * can be precalculated and stored in the lookup table colorindex[].
- * colorindex[i][j] maps pixel value j in component i to the nearest
- * representative value (grid plane) for that component; this index is
- * multiplied by the array stride for component i, so that the
- * index of the colormap entry closest to a given pixel value is just
- * sum( colorindex[component-number][pixel-component-value] )
- * Aside from being fast, this scheme allows for variable spacing between
- * representative values with no additional lookup cost.
- *
- * If gamma correction has been applied in color conversion, it might be wise
- * to adjust the color grid spacing so that the representative colors are
- * equidistant in linear space. At this writing, gamma correction is not
- * implemented by jdcolor, so nothing is done here.

-/* Declarations for ordered dithering.
- *
- * We use a standard 16x16 ordered dither array. The basic concept of ordered
- * dithering is described in many references, for instance Dale Schumacher's
- * chapter II.2 of Graphics Gems II (James Arvo, ed. Academic Press, 1991).
- * In place of Schumacher's comparisons against a "threshold" value, we add a
- * "dither" value to the input pixel and then round the result to the nearest
- * output value. The dither value is equivalent to (0.5 - threshold) times
- * the distance between output values. For ordered dithering, we assume that
- * the output colors are equally spaced; if not, results will probably be
- * worse, since the dither may be too much or too little at a given point.
- *
- * The normal calculation would be to form pixel value + dither, range-limit
- * this to 0..MAXJSAMPLE, and then index into the colorindex table as usual.
- * We can skip the separate range-limiting step by extending the colorindex
- * table in both directions.

- * This module implements the well-known Heckbert paradigm for color
- * quantization. Most of the ideas used here can be traced back to
- * Heckbert's seminal paper
- * Heckbert, Paul. "Color Image Quantization for Frame Buffer Display",
- * Proc. SIGGRAPH '82, Computer Graphics v.16 #3 (July 1982), pp 297-304.
- *
- * In the first pass over the image, we accumulate a histogram showing the
- * usage count of each possible color. To keep the histogram to a reasonable
- * size, we reduce the precision of the input; typical practice is to retain
- * 5 or 6 bits per color, so that 8 or 4 different input values are counted
- * in the same histogram cell.
- *
- * Next, the color-selection step begins with a box representing the whole
- * color space, and repeatedly splits the "largest" remaining box until we
- * have as many boxes as desired colors. Then the mean color in each
- * remaining box becomes one of the possible output colors.
- *
- * The second pass over the image maps each input pixel to the closest output
- * color (optionally after applying a Floyd-Steinberg dithering correction).
- * This mapping is logically trivial, but making it go fast enough requires
- * considerable care.
- *
- * Heckbert-style quantizers vary a good deal in their policies for choosing
- * the "largest" box and deciding where to cut it. The particular policies
- * used here have proved out well in experimental comparisons, but better ones
- * may yet be found.
- *
- * In earlier versions of the IJG code, this module quantized in YCbCr color
- * space, processing the raw upsampled data without a color conversion step.
- * This allowed the color conversion math to be done only once per colormap
- * entry, not once per pixel. However, that optimization precluded other
- * useful optimizations (such as merging color conversion with upsampling)
- * and it also interfered with desired capabilities such as quantizing to an
- * externally-supplied colormap. We have therefore abandoned that approach.
- * The present code works in the post-conversion color space, typically RGB.
- *
- * To improve the visual quality of the results, we actually work in scaled
- * RGB space, giving G distances more weight than R, and R in turn more than
- * B. To do everything in integer math, we must use integer scale factors.
- * The 2/3/1 scale factors used here correspond loosely to the relative
- * weights of the colors in the NTSC grayscale equation.
- * If you want to use this code to quantize a non-RGB color space, you'll
- * probably need to change these scale factors.

- * you'll get compile errors until you extend this logic. In that case

- * First we have the histogram data structure and routines for creating it.
- *
- * The number of bits of precision can be adjusted by changing these symbols.
- * We recommend keeping 6 bits for G and 5 each for R and B.
- * If you have plenty of memory and cycles, 6 bits all around gives marginally
- * better results; if you are short of memory, 5 bits all around will save
- * some space but degrade the results.
- * To maintain a fully accurate histogram, we'd need to allocate a "long"
- * (preferably unsigned long) for each cell. In practice this is overkill;
- * we can get by with 16 bits per cell. Few of the cell counts will overflow,
- * and clamping those that do overflow to the maximum value will give close-
- * enough results. This reduces the recommended histogram size from 256Kb
- * to 128Kb, which is a useful savings on PC-class machines.
- * (In the second pass the histogram space is re-used for pixel mapping data;
- * in that capacity, each cell must be able to store zero to the number of
- * desired colors. 16 bits/cell is plenty for that too.)
- * Since the JPEG code is intended to run in small memory model on 80x86
- * machines, we can't just allocate the histogram in one chunk. Instead
- * of a true 3-D array, we use a row of pointers to 2-D arrays. Each
- * pointer corresponds to a C0 value (typically 2^5 = 32 pointers) and
- * each 2-D array has 2^6*2^5 = 2048 or 2^6*2^6 = 4096 entries. Note that
- * on 80x86 machines, the pointer row is in near memory but the actual
- * arrays are in far memory (same arrangement as we use for image arrays).

- * These routines are concerned with the time-critical task of mapping input
- * colors to the nearest color in the selected colormap.
- *
- * We re-use the histogram space as an "inverse color map", essentially a
- * cache for the results of nearest-color searches. All colors within a
- * histogram cell will be mapped to the same colormap entry, namely the one
- * closest to the cell's center. This may not be quite the closest entry to
- * the actual input color, but it's almost as good. A zero in the cache
- * indicates we haven't found the nearest color for that cell yet; the array
- * is cleared to zeroes before starting the mapping pass. When we find the
- * nearest color for a cell, its colormap index plus one is recorded in the
- * cache for future use. The pass2 scanning routines call fill_inverse_cmap
- * when they need to use an unfilled entry in the cache.
- *
- * Our method of efficiently finding nearest colors is based on the "locally
- * sorted search" idea described by Heckbert and on the incremental distance
- * calculation described by Spencer W. Thomas in chapter III.1 of Graphics
- * Gems II (James Arvo, ed. Academic Press, 1991). Thomas points out that
- * the distances from a given colormap entry to each cell of the histogram can
- * be computed quickly using an incremental method: the differences between
- * distances to adjacent cells themselves differ by a constant. This allows a
- * fairly fast implementation of the "brute force" approach of computing the
- * distance from every colormap entry to every histogram cell. Unfortunately,
- * it needs a work array to hold the best-distance-so-far for each histogram
- * cell (because the inner loop has to be over cells, not colormap entries).
- * The work array elements have to be INT32s, so the work array would need
- * 256Kb at our recommended precision. This is not feasible in DOS machines.
- *
- * To get around these problems, we apply Thomas' method to compute the
- * nearest colors for only the cells within a small subbox of the histogram.
- * The work array need be only as big as the subbox, so the memory usage
- * problem is solved. Furthermore, we need not fill subboxes that are never
- * referenced in pass2; many images use only part of the color gamut, so a
- * fair amount of work is saved. An additional advantage of this
- * approach is that we can apply Heckbert's locality criterion to quickly
- * eliminate colormap entries that are far away from the subbox; typically
- * three-fourths of the colormap entries are rejected by Heckbert's criterion,
- * and we need not compute their distances to individual cells in the subbox.
- * The speed of this approach is heavily influenced by the subbox size: too
- * small means too much overhead, too big loses because Heckbert's criterion
- * can't eliminate as many colormap entries. Empirically the best subbox
- * size seems to be about 1/512th of the histogram (1/8th in each direction).
- *
- * Thomas' article also describes a refined method which is asymptotically
- * faster than the brute-force method, but it is also far more complex and
- * cannot efficiently be applied to small subboxes. It is therefore not
- * useful for programs intended to be portable to DOS machines. On machines
- * with plenty of memory, filling the whole histogram in one shot with Thomas'
- * refined method might be faster than the present code --- but then again,
- * it might not be any faster, and it's certainly more complicated.

-USING THE IJG JPEG LIBRARY
-
-Copyright (C) 1994-2013, Thomas G. Lane, Guido Vollbeding.
-This file is part of the Independent JPEG Group's software.
-For conditions of distribution and use, see the accompanying README file.
-
-
-This file describes how to use the IJG JPEG library within an application
-program. Read it if you want to write a program that uses the library.
-
-The file example.c provides heavily commented skeleton code for calling the
-JPEG library. Also see jpeglib.h (the include file to be used by application
-programs) for full details about data structures and function parameter lists.
-The library source code, of course, is the ultimate reference.
-
-Note that there have been *major* changes from the application interface
-presented by IJG version 4 and earlier versions. The old design had several
-inherent limitations, and it had accumulated a lot of cruft as we added
-features while trying to minimize application-interface changes. We have
-sacrificed backward compatibility in the version 5 rewrite, but we think the
-improvements justify this.

-OVERVIEW
-========
-
-Functions provided by the library
----------------------------------
-
-The IJG JPEG library provides C code to read and write JPEG-compressed image
-files. The surrounding application program receives or supplies image data a
-scanline at a time, using a straightforward uncompressed image format. All
-details of color conversion and other preprocessing/postprocessing can be
-handled by the library.
-
-The library includes a substantial amount of code that is not covered by the
-JPEG standard but is necessary for typical applications of JPEG. These
-functions preprocess the image before JPEG compression or postprocess it after
-decompression. They include colorspace conversion, downsampling/upsampling,
-and color quantization. The application indirectly selects use of this code
-by specifying the format in which it wishes to supply or receive image data.
-For example, if colormapped output is requested, then the decompression
-library automatically invokes color quantization.
-
-A wide range of quality vs. speed tradeoffs are possible in JPEG processing,
-and even more so in decompression postprocessing. The decompression library
-provides multiple implementations that cover most of the useful tradeoffs,
-ranging from very-high-quality down to fast-preview operation. On the
-compression side we have generally not provided low-quality choices, since
-compression is normally less time-critical. It should be understood that the
-low-quality modes may not meet the JPEG standard's accuracy requirements;
-nonetheless, they are useful for viewers.
-
-A word about functions *not* provided by the library. We handle a subset of
-the ISO JPEG standard; most baseline, extended-sequential, and progressive
-JPEG processes are supported. (Our subset includes all features now in common
-use.) Unsupported ISO options include:
- * Hierarchical storage
- * Lossless JPEG
- * DNL marker
- * Nonintegral subsampling ratios
-We support 8-bit to 12-bit data precision, but this is a compile-time choice
-rather than a run-time choice; hence it is difficult to use different
-precisions in a single application.
-
-By itself, the library handles only interchange JPEG datastreams --- in
-particular the widely used JFIF file format. The library can be used by
-surrounding code to process interchange or abbreviated JPEG datastreams that
-are embedded in more complex file formats. (For example, this library is
-used by the free LIBTIFF library to support JPEG compression in TIFF.)
-
-
-Outline of typical usage
-------------------------
-
-The rough outline of a JPEG compression operation is:
-
- Allocate and initialize a JPEG compression object
- Specify the destination for the compressed data (eg, a file)
- Set parameters for compression, including image size & colorspace
- jpeg_start_compress(...);
- while (scan lines remain to be written)
- jpeg_write_scanlines(...);
- jpeg_finish_compress(...);
- Release the JPEG compression object
-
-A JPEG compression object holds parameters and working state for the JPEG
-library. We make creation/destruction of the object separate from starting
-or finishing compression of an image; the same object can be re-used for a
-series of image compression operations. This makes it easy to re-use the
-same parameter settings for a sequence of images. Re-use of a JPEG object
-also has important implications for processing abbreviated JPEG datastreams,
-as discussed later.
-
-The image data to be compressed is supplied to jpeg_write_scanlines() from
-in-memory buffers. If the application is doing file-to-file compression,
-reading image data from the source file is the application's responsibility.
-The library emits compressed data by calling a "data destination manager",
-which typically will write the data into a file; but the application can
-provide its own destination manager to do something else.
-
-Similarly, the rough outline of a JPEG decompression operation is:
-
- Allocate and initialize a JPEG decompression object
- Specify the source of the compressed data (eg, a file)
- Call jpeg_read_header() to obtain image info
- Set parameters for decompression
- jpeg_start_decompress(...);
- while (scan lines remain to be read)
- jpeg_read_scanlines(...);
- jpeg_finish_decompress(...);
- Release the JPEG decompression object
-
-This is comparable to the compression outline except that reading the
-datastream header is a separate step. This is helpful because information
-about the image's size, colorspace, etc is available when the application
-selects decompression parameters. For example, the application can choose an
-output scaling ratio that will fit the image into the available screen size.
-
-The decompression library obtains compressed data by calling a data source
-manager, which typically will read the data from a file; but other behaviors
-can be obtained with a custom source manager. Decompressed data is delivered
-into in-memory buffers passed to jpeg_read_scanlines().
-
-It is possible to abort an incomplete compression or decompression operation
-by calling jpeg_abort(); or, if you do not need to retain the JPEG object,
-simply release it by calling jpeg_destroy().
-
-JPEG compression and decompression objects are two separate struct types.
-However, they share some common fields, and certain routines such as
-jpeg_destroy() can work on either type of object.
-
-The JPEG library has no static variables: all state is in the compression
-or decompression object. Therefore it is possible to process multiple
-compression and decompression operations concurrently, using multiple JPEG
-objects.
-
-Both compression and decompression can be done in an incremental memory-to-
-memory fashion, if suitable source/destination managers are used. See the
-section on "I/O suspension" for more details.
-
-
-BASIC LIBRARY USAGE
-===================
-
-Data formats
-------------
-
-Before diving into procedural details, it is helpful to understand the
-image data format that the JPEG library expects or returns.
-
-The standard input image format is a rectangular array of pixels, with each
-pixel having the same number of "component" or "sample" values (color
-channels). You must specify how many components there are and the colorspace
-interpretation of the components. Most applications will use RGB data
-(three components per pixel) or grayscale data (one component per pixel).
-PLEASE NOTE THAT RGB DATA IS THREE SAMPLES PER PIXEL, GRAYSCALE ONLY ONE.
-A remarkable number of people manage to miss this, only to find that their
-programs don't work with grayscale JPEG files.
-
-There is no provision for colormapped input. JPEG files are always full-color
-or full grayscale (or sometimes another colorspace such as CMYK). You can
-feed in a colormapped image by expanding it to full-color format. However
-JPEG often doesn't work very well with source data that has been colormapped,
-because of dithering noise. This is discussed in more detail in the JPEG FAQ
-and the other references mentioned in the README file.
-
-Pixels are stored by scanlines, with each scanline running from left to
-right. The component values for each pixel are adjacent in the row; for
-example, R,G,B,R,G,B,R,G,B,... for 24-bit RGB color. Each scanline is an
-array of data type JSAMPLE --- which is typically "unsigned char", unless
-you've changed jmorecfg.h. (You can also change the RGB pixel layout, say
-to B,G,R order, by modifying jmorecfg.h. But see the restrictions listed in
-that file before doing so.)
-
-A 2-D array of pixels is formed by making a list of pointers to the starts of
-scanlines; so the scanlines need not be physically adjacent in memory. Even
-if you process just one scanline at a time, you must make a one-element
-pointer array to conform to this structure. Pointers to JSAMPLE rows are of
-type JSAMPROW, and the pointer to the pointer array is of type JSAMPARRAY.
-
-The library accepts or supplies one or more complete scanlines per call.
-It is not possible to process part of a row at a time. Scanlines are always
-processed top-to-bottom. You can process an entire image in one call if you
-have it all in memory, but usually it's simplest to process one scanline at
-a time.
-
-For best results, source data values should have the precision specified by
-BITS_IN_JSAMPLE (normally 8 bits). For instance, if you choose to compress
-data that's only 6 bits/channel, you should left-justify each value in a
-byte before passing it to the compressor. If you need to compress data
-that has more than 8 bits/channel, compile with BITS_IN_JSAMPLE = 9 to 12.
-(See "Library compile-time options", later.)
-
-
-The data format returned by the decompressor is the same in all details,
-except that colormapped output is supported. (Again, a JPEG file is never
-colormapped. But you can ask the decompressor to perform on-the-fly color
-quantization to deliver colormapped output.) If you request colormapped
-output then the returned data array contains a single JSAMPLE per pixel;
-its value is an index into a color map. The color map is represented as
-a 2-D JSAMPARRAY in which each row holds the values of one color component,
-that is, colormap[i][j] is the value of the i'th color component for pixel
-value (map index) j. Note that since the colormap indexes are stored in
-JSAMPLEs, the maximum number of colors is limited by the size of JSAMPLE
-(ie, at most 256 colors for an 8-bit JPEG library).
-
-
-Compression details
--------------------
-
-Here we revisit the JPEG compression outline given in the overview.
-
-1. Allocate and initialize a JPEG compression object.
-
-A JPEG compression object is a "struct jpeg_compress_struct". (It also has
-a bunch of subsidiary structures which are allocated via malloc(), but the
-application doesn't control those directly.) This struct can be just a local
-variable in the calling routine, if a single routine is going to execute the
-whole JPEG compression sequence. Otherwise it can be static or allocated
-from malloc().
-
-You will also need a structure representing a JPEG error handler. The part
-of this that the library cares about is a "struct jpeg_error_mgr". If you
-are providing your own error handler, you'll typically want to embed the
-jpeg_error_mgr struct in a larger structure; this is discussed later under
-"Error handling". For now we'll assume you are just using the default error
-handler. The default error handler will print JPEG error/warning messages
-on stderr, and it will call exit() if a fatal error occurs.
-
-You must initialize the error handler structure, store a pointer to it into
-the JPEG object's "err" field, and then call jpeg_create_compress() to
-initialize the rest of the JPEG object.
-
-Typical code for this step, if you are using the default error handler, is
-
- struct jpeg_compress_struct cinfo;
- struct jpeg_error_mgr jerr;
- ...
- cinfo.err = jpeg_std_error(&jerr);
- jpeg_create_compress(&cinfo);
-
-jpeg_create_compress allocates a small amount of memory, so it could fail
-if you are out of memory. In that case it will exit via the error handler;
-that's why the error handler must be initialized first.
-
-
-2. Specify the destination for the compressed data (eg, a file).
-
-As previously mentioned, the JPEG library delivers compressed data to a
-"data destination" module. The library includes one data destination
-module which knows how to write to a stdio stream. You can use your own
-destination module if you want to do something else, as discussed later.
-
-If you use the standard destination module, you must open the target stdio
-stream beforehand. Typical code for this step looks like:
-
- FILE * outfile;
- ...
- if ((outfile = fopen(filename, "wb")) == NULL) {
- fprintf(stderr, "can't open %s\n", filename);
- exit(1);
- }
- jpeg_stdio_dest(&cinfo, outfile);
-
-where the last line invokes the standard destination module.
-
-WARNING: it is critical that the binary compressed data be delivered to the
-output file unchanged. On non-Unix systems the stdio library may perform
-newline translation or otherwise corrupt binary data. To suppress this
-behavior, you may need to use a "b" option to fopen (as shown above), or use
-setmode() or another routine to put the stdio stream in binary mode. See
-cjpeg.c and djpeg.c for code that has been found to work on many systems.
-
-You can select the data destination after setting other parameters (step 3),
-if that's more convenient. You may not change the destination between
-calling jpeg_start_compress() and jpeg_finish_compress().
-
-
-3. Set parameters for compression, including image size & colorspace.
-
-You must supply information about the source image by setting the following
-fields in the JPEG object (cinfo structure):
-
- image_width Width of image, in pixels
- image_height Height of image, in pixels
- input_components Number of color channels (samples per pixel)
- in_color_space Color space of source image
-
-The image dimensions are, hopefully, obvious. JPEG supports image dimensions
-of 1 to 64K pixels in either direction. The input color space is typically
-RGB or grayscale, and input_components is 3 or 1 accordingly. (See "Special
-color spaces", later, for more info.) The in_color_space field must be
-assigned one of the J_COLOR_SPACE enum constants, typically JCS_RGB or
-JCS_GRAYSCALE.
-
-JPEG has a large number of compression parameters that determine how the
-image is encoded. Most applications don't need or want to know about all
-these parameters. You can set all the parameters to reasonable defaults by
-calling jpeg_set_defaults(); then, if there are particular values you want
-to change, you can do so after that. The "Compression parameter selection"
-section tells about all the parameters.
-
-You must set in_color_space correctly before calling jpeg_set_defaults(),
-because the defaults depend on the source image colorspace. However the
-other three source image parameters need not be valid until you call
-jpeg_start_compress(). There's no harm in calling jpeg_set_defaults() more
-than once, if that happens to be convenient.
-
-Typical code for a 24-bit RGB source image is
-
- cinfo.image_width = Width; /* image width and height, in pixels */
- cinfo.image_height = Height;
- cinfo.input_components = 3; /* # of color components per pixel */
- cinfo.in_color_space = JCS_RGB; /* colorspace of input image */
-
- jpeg_set_defaults(&cinfo);
- /* Make optional parameter settings here */
-
-
-4. jpeg_start_compress(...);
-
-After you have established the data destination and set all the necessary
-source image info and other parameters, call jpeg_start_compress() to begin
-a compression cycle. This will initialize internal state, allocate working
-storage, and emit the first few bytes of the JPEG datastream header.
-
-Typical code:
-
- jpeg_start_compress(&cinfo, TRUE);
-
-The "TRUE" parameter ensures that a complete JPEG interchange datastream
-will be written. This is appropriate in most cases. If you think you might
-want to use an abbreviated datastream, read the section on abbreviated
-datastreams, below.
-
-Once you have called jpeg_start_compress(), you may not alter any JPEG
-parameters or other fields of the JPEG object until you have completed
-the compression cycle.
-
-
-5. while (scan lines remain to be written)
- jpeg_write_scanlines(...);
-
-Now write all the required image data by calling jpeg_write_scanlines()
-one or more times. You can pass one or more scanlines in each call, up
-to the total image height. In most applications it is convenient to pass
-just one or a few scanlines at a time. The expected format for the passed
-data is discussed under "Data formats", above.
-
-Image data should be written in top-to-bottom scanline order. The JPEG spec
-contains some weasel wording about how top and bottom are application-defined
-terms (a curious interpretation of the English language...) but if you want
-your files to be compatible with everyone else's, you WILL use top-to-bottom
-order. If the source data must be read in bottom-to-top order, you can use
-the JPEG library's virtual array mechanism to invert the data efficiently.
-Examples of this can be found in the sample application cjpeg.
-
-The library maintains a count of the number of scanlines written so far
-in the next_scanline field of the JPEG object. Usually you can just use
-this variable as the loop counter, so that the loop test looks like
-"while (cinfo.next_scanline < cinfo.image_height)".
-
-Code for this step depends heavily on the way that you store the source data.
-example.c shows the following code for the case of a full-size 2-D source
-array containing 3-byte RGB pixels:
-
- JSAMPROW row_pointer[1]; /* pointer to a single row */
- int row_stride; /* physical row width in buffer */
-
- row_stride = image_width * 3; /* JSAMPLEs per row in image_buffer */
-
- while (cinfo.next_scanline < cinfo.image_height) {
- row_pointer[0] = & image_buffer[cinfo.next_scanline * row_stride];
- jpeg_write_scanlines(&cinfo, row_pointer, 1);
- }
-
-jpeg_write_scanlines() returns the number of scanlines actually written.
-This will normally be equal to the number passed in, so you can usually
-ignore the return value. It is different in just two cases:
- * If you try to write more scanlines than the declared image height,
- the additional scanlines are ignored.
- * If you use a suspending data destination manager, output buffer overrun
- will cause the compressor to return before accepting all the passed lines.
- This feature is discussed under "I/O suspension", below. The normal
- stdio destination manager will NOT cause this to happen.
-In any case, the return value is the same as the change in the value of
-next_scanline.
-
-
-6. jpeg_finish_compress(...);
-
-After all the image data has been written, call jpeg_finish_compress() to
-complete the compression cycle. This step is ESSENTIAL to ensure that the
-last bufferload of data is written to the data destination.
-jpeg_finish_compress() also releases working memory associated with the JPEG
-object.
-
-Typical code:
-
- jpeg_finish_compress(&cinfo);
-
-If using the stdio destination manager, don't forget to close the output
-stdio stream (if necessary) afterwards.
-
-If you have requested a multi-pass operating mode, such as Huffman code
-optimization, jpeg_finish_compress() will perform the additional passes using
-data buffered by the first pass. In this case jpeg_finish_compress() may take
-quite a while to complete. With the default compression parameters, this will
-not happen.
-
-It is an error to call jpeg_finish_compress() before writing the necessary
-total number of scanlines. If you wish to abort compression, call
-jpeg_abort() as discussed below.
-
-After completing a compression cycle, you may dispose of the JPEG object
-as discussed next, or you may use it to compress another image. In that case
-return to step 2, 3, or 4 as appropriate. If you do not change the
-destination manager, the new datastream will be written to the same target.
-If you do not change any JPEG parameters, the new datastream will be written
-with the same parameters as before. Note that you can change the input image
-dimensions freely between cycles, but if you change the input colorspace, you
-should call jpeg_set_defaults() to adjust for the new colorspace; and then
-you'll need to repeat all of step 3.
-
-
-7. Release the JPEG compression object.
-
-When you are done with a JPEG compression object, destroy it by calling
-jpeg_destroy_compress(). This will free all subsidiary memory (regardless of
-the previous state of the object). Or you can call jpeg_destroy(), which
-works for either compression or decompression objects --- this may be more
-convenient if you are sharing code between compression and decompression
-cases. (Actually, these routines are equivalent except for the declared type
-of the passed pointer. To avoid gripes from ANSI C compilers, jpeg_destroy()
-should be passed a j_common_ptr.)
-
-If you allocated the jpeg_compress_struct structure from malloc(), freeing
-it is your responsibility --- jpeg_destroy() won't. Ditto for the error
-handler structure.
-
-Typical code:
-
- jpeg_destroy_compress(&cinfo);
-
-
-8. Aborting.
-
-If you decide to abort a compression cycle before finishing, you can clean up
-in either of two ways:
-
-* If you don't need the JPEG object any more, just call
- jpeg_destroy_compress() or jpeg_destroy() to release memory. This is
- legitimate at any point after calling jpeg_create_compress() --- in fact,
- it's safe even if jpeg_create_compress() fails.
-
-* If you want to re-use the JPEG object, call jpeg_abort_compress(), or call
- jpeg_abort() which works on both compression and decompression objects.
- This will return the object to an idle state, releasing any working memory.
- jpeg_abort() is allowed at any time after successful object creation.
-
-Note that cleaning up the data destination, if required, is your
-responsibility; neither of these routines will call term_destination().
-(See "Compressed data handling", below, for more about that.)
-
-jpeg_destroy() and jpeg_abort() are the only safe calls to make on a JPEG
-object that has reported an error by calling error_exit (see "Error handling"
-for more info). The internal state of such an object is likely to be out of
-whack. Either of these two routines will return the object to a known state.
-
-
-Decompression details
----------------------
-
-Here we revisit the JPEG decompression outline given in the overview.
-
-1. Allocate and initialize a JPEG decompression object.
-
-This is just like initialization for compression, as discussed above,
-except that the object is a "struct jpeg_decompress_struct" and you
-call jpeg_create_decompress(). Error handling is exactly the same.
-
-Typical code:
-
- struct jpeg_decompress_struct cinfo;
- struct jpeg_error_mgr jerr;
- ...
- cinfo.err = jpeg_std_error(&jerr);
- jpeg_create_decompress(&cinfo);
-
-(Both here and in the IJG code, we usually use variable name "cinfo" for
-both compression and decompression objects.)
-
-
-2. Specify the source of the compressed data (eg, a file).
-
-As previously mentioned, the JPEG library reads compressed data from a "data
-source" module. The library includes one data source module which knows how
-to read from a stdio stream. You can use your own source module if you want
-to do something else, as discussed later.
-
-If you use the standard source module, you must open the source stdio stream
-beforehand. Typical code for this step looks like:
-
- FILE * infile;
- ...
- if ((infile = fopen(filename, "rb")) == NULL) {
- fprintf(stderr, "can't open %s\n", filename);
- exit(1);
- }
- jpeg_stdio_src(&cinfo, infile);
-
-where the last line invokes the standard source module.
-
-WARNING: it is critical that the binary compressed data be read unchanged.
-On non-Unix systems the stdio library may perform newline translation or
-otherwise corrupt binary data. To suppress this behavior, you may need to use
-a "b" option to fopen (as shown above), or use setmode() or another routine to
-put the stdio stream in binary mode. See cjpeg.c and djpeg.c for code that
-has been found to work on many systems.
-
-You may not change the data source between calling jpeg_read_header() and
-jpeg_finish_decompress(). If you wish to read a series of JPEG images from
-a single source file, you should repeat the jpeg_read_header() to
-jpeg_finish_decompress() sequence without reinitializing either the JPEG
-object or the data source module; this prevents buffered input data from
-being discarded.
-
-
-3. Call jpeg_read_header() to obtain image info.
-
-Typical code for this step is just
-
- jpeg_read_header(&cinfo, TRUE);
-
-This will read the source datastream header markers, up to the beginning
-of the compressed data proper. On return, the image dimensions and other
-info have been stored in the JPEG object. The application may wish to
-consult this information before selecting decompression parameters.
-
-More complex code is necessary if
- * A suspending data source is used --- in that case jpeg_read_header()
- may return before it has read all the header data. See "I/O suspension",
- below. The normal stdio source manager will NOT cause this to happen.
- * Abbreviated JPEG files are to be processed --- see the section on
- abbreviated datastreams. Standard applications that deal only in
- interchange JPEG files need not be concerned with this case either.
-
-It is permissible to stop at this point if you just wanted to find out the
-image dimensions and other header info for a JPEG file. In that case,
-call jpeg_destroy() when you are done with the JPEG object, or call
-jpeg_abort() to return it to an idle state before selecting a new data
-source and reading another header.
-
-
-4. Set parameters for decompression.
-
-jpeg_read_header() sets appropriate default decompression parameters based on
-the properties of the image (in particular, its colorspace). However, you
-may well want to alter these defaults before beginning the decompression.
-For example, the default is to produce full color output from a color file.
-If you want colormapped output you must ask for it. Other options allow the
-returned image to be scaled and allow various speed/quality tradeoffs to be
-selected. "Decompression parameter selection", below, gives details.
-
-If the defaults are appropriate, nothing need be done at this step.
-
-Note that all default values are set by each call to jpeg_read_header().
-If you reuse a decompression object, you cannot expect your parameter
-settings to be preserved across cycles, as you can for compression.
-You must set desired parameter values each time.
-
-
-5. jpeg_start_decompress(...);
-
-Once the parameter values are satisfactory, call jpeg_start_decompress() to
-begin decompression. This will initialize internal state, allocate working
-memory, and prepare for returning data.
-
-Typical code is just
-
- jpeg_start_decompress(&cinfo);
-
-If you have requested a multi-pass operating mode, such as 2-pass color
-quantization, jpeg_start_decompress() will do everything needed before data
-output can begin. In this case jpeg_start_decompress() may take quite a while
-to complete. With a single-scan (non progressive) JPEG file and default
-decompression parameters, this will not happen; jpeg_start_decompress() will
-return quickly.
-
-After this call, the final output image dimensions, including any requested
-scaling, are available in the JPEG object; so is the selected colormap, if
-colormapped output has been requested. Useful fields include
-
- output_width image width and height, as scaled
- output_height
- out_color_components # of color components in out_color_space
- output_components # of color components returned per pixel
- colormap the selected colormap, if any
- actual_number_of_colors number of entries in colormap
-
-output_components is 1 (a colormap index) when quantizing colors; otherwise it
-equals out_color_components. It is the number of JSAMPLE values that will be
-emitted per pixel in the output arrays.
-
-Typically you will need to allocate data buffers to hold the incoming image.
-You will need output_width * output_components JSAMPLEs per scanline in your
-output buffer, and a total of output_height scanlines will be returned.
-
-Note: if you are using the JPEG library's internal memory manager to allocate
-data buffers (as djpeg does), then the manager's protocol requires that you
-request large buffers *before* calling jpeg_start_decompress(). This is a
-little tricky since the output_XXX fields are not normally valid then. You
-can make them valid by calling jpeg_calc_output_dimensions() after setting the
-relevant parameters (scaling, output color space, and quantization flag).
-
-
-6. while (scan lines remain to be read)
- jpeg_read_scanlines(...);
-
-Now you can read the decompressed image data by calling jpeg_read_scanlines()
-one or more times. At each call, you pass in the maximum number of scanlines
-to be read (ie, the height of your working buffer); jpeg_read_scanlines()
-will return up to that many lines. The return value is the number of lines
-actually read. The format of the returned data is discussed under "Data
-formats", above. Don't forget that grayscale and color JPEGs will return
-different data formats!
-
-Image data is returned in top-to-bottom scanline order. If you must write
-out the image in bottom-to-top order, you can use the JPEG library's virtual
-array mechanism to invert the data efficiently. Examples of this can be
-found in the sample application djpeg.
-
-The library maintains a count of the number of scanlines returned so far
-in the output_scanline field of the JPEG object. Usually you can just use
-this variable as the loop counter, so that the loop test looks like
-"while (cinfo.output_scanline < cinfo.output_height)". (Note that the test
-should NOT be against image_height, unless you never use scaling. The
-image_height field is the height of the original unscaled image.)
-The return value always equals the change in the value of output_scanline.
-
-If you don't use a suspending data source, it is safe to assume that
-jpeg_read_scanlines() reads at least one scanline per call, until the
-bottom of the image has been reached.
-
-If you use a buffer larger than one scanline, it is NOT safe to assume that
-jpeg_read_scanlines() fills it. (The current implementation returns only a
-few scanlines per call, no matter how large a buffer you pass.) So you must
-always provide a loop that calls jpeg_read_scanlines() repeatedly until the
-whole image has been read.
-
-
-7. jpeg_finish_decompress(...);
-
-After all the image data has been read, call jpeg_finish_decompress() to
-complete the decompression cycle. This causes working memory associated
-with the JPEG object to be released.
-
-Typical code:
-
- jpeg_finish_decompress(&cinfo);
-
-If using the stdio source manager, don't forget to close the source stdio
-stream if necessary.
-
-It is an error to call jpeg_finish_decompress() before reading the correct
-total number of scanlines. If you wish to abort decompression, call
-jpeg_abort() as discussed below.
-
-After completing a decompression cycle, you may dispose of the JPEG object as
-discussed next, or you may use it to decompress another image. In that case
-return to step 2 or 3 as appropriate. If you do not change the source
-manager, the next image will be read from the same source.
-
-
-8. Release the JPEG decompression object.
-
-When you are done with a JPEG decompression object, destroy it by calling
-jpeg_destroy_decompress() or jpeg_destroy(). The previous discussion of
-destroying compression objects applies here too.
-
-Typical code:
-
- jpeg_destroy_decompress(&cinfo);
-
-
-9. Aborting.
-
-You can abort a decompression cycle by calling jpeg_destroy_decompress() or
-jpeg_destroy() if you don't need the JPEG object any more, or
-jpeg_abort_decompress() or jpeg_abort() if you want to reuse the object.
-The previous discussion of aborting compression cycles applies here too.
-
-
-Mechanics of usage: include files, linking, etc
------------------------------------------------
-
-Applications using the JPEG library should include the header file jpeglib.h
-to obtain declarations of data types and routines. Before including
-jpeglib.h, include system headers that define at least the typedefs FILE and
-size_t. On ANSI-conforming systems, including is sufficient; on
-older Unix systems, you may need to define size_t.
-
-If the application needs to refer to individual JPEG library error codes, also
-include jerror.h to define those symbols.
-
-jpeglib.h indirectly includes the files jconfig.h and jmorecfg.h. If you are
-installing the JPEG header files in a system directory, you will want to
-install all four files: jpeglib.h, jerror.h, jconfig.h, jmorecfg.h.
-
-The most convenient way to include the JPEG code into your executable program
-is to prepare a library file ("libjpeg.a", or a corresponding name on non-Unix
-machines) and reference it at your link step. If you use only half of the
-library (only compression or only decompression), only that much code will be
-included from the library, unless your linker is hopelessly brain-damaged.
-The supplied makefiles build libjpeg.a automatically (see install.txt).
-
-While you can build the JPEG library as a shared library if the whim strikes
-you, we don't really recommend it. The trouble with shared libraries is that
-at some point you'll probably try to substitute a new version of the library
-without recompiling the calling applications. That generally doesn't work
-because the parameter struct declarations usually change with each new
-version. In other words, the library's API is *not* guaranteed binary
-compatible across versions; we only try to ensure source-code compatibility.
-(In hindsight, it might have been smarter to hide the parameter structs from
-applications and introduce a ton of access functions instead. Too late now,
-however.)
-
-On some systems your application may need to set up a signal handler to ensure
-that temporary files are deleted if the program is interrupted. This is most
-critical if you are on MS-DOS and use the jmemdos.c memory manager back end;
-it will try to grab extended memory for temp files, and that space will NOT be
-freed automatically. See cjpeg.c or djpeg.c for an example signal handler.
-
-It may be worth pointing out that the core JPEG library does not actually
-require the stdio library: only the default source/destination managers and
-error handler need it. You can use the library in a stdio-less environment
-if you replace those modules and use jmemnobs.c (or another memory manager of
-your own devising). More info about the minimum system library requirements
-may be found in jinclude.h.
-
-
-ADVANCED FEATURES
-=================
-
-Compression parameter selection
--------------------------------
-
-This section describes all the optional parameters you can set for JPEG
-compression, as well as the "helper" routines provided to assist in this
-task. Proper setting of some parameters requires detailed understanding
-of the JPEG standard; if you don't know what a parameter is for, it's best
-not to mess with it! See REFERENCES in the README file for pointers to
-more info about JPEG.
-
-It's a good idea to call jpeg_set_defaults() first, even if you plan to set
-all the parameters; that way your code is more likely to work with future JPEG
-libraries that have additional parameters. For the same reason, we recommend
-you use a helper routine where one is provided, in preference to twiddling
-cinfo fields directly.
-
-The helper routines are:
-
-jpeg_set_defaults (j_compress_ptr cinfo)
- This routine sets all JPEG parameters to reasonable defaults, using
- only the input image's color space (field in_color_space, which must
- already be set in cinfo). Many applications will only need to use
- this routine and perhaps jpeg_set_quality().
-
-jpeg_set_colorspace (j_compress_ptr cinfo, J_COLOR_SPACE colorspace)
- Sets the JPEG file's colorspace (field jpeg_color_space) as specified,
- and sets other color-space-dependent parameters appropriately. See
- "Special color spaces", below, before using this. A large number of
- parameters, including all per-component parameters, are set by this
- routine; if you want to twiddle individual parameters you should call
- jpeg_set_colorspace() before rather than after.
-
-jpeg_default_colorspace (j_compress_ptr cinfo)
- Selects an appropriate JPEG colorspace based on cinfo->in_color_space,
- and calls jpeg_set_colorspace(). This is actually a subroutine of
- jpeg_set_defaults(). It's broken out in case you want to change
- just the colorspace-dependent JPEG parameters.
-
-jpeg_set_quality (j_compress_ptr cinfo, int quality, boolean force_baseline)
- Constructs JPEG quantization tables appropriate for the indicated
- quality setting. The quality value is expressed on the 0..100 scale
- recommended by IJG (cjpeg's "-quality" switch uses this routine).
- Note that the exact mapping from quality values to tables may change
- in future IJG releases as more is learned about DCT quantization.
- If the force_baseline parameter is TRUE, then the quantization table
- entries are constrained to the range 1..255 for full JPEG baseline
- compatibility. In the current implementation, this only makes a
- difference for quality settings below 25, and it effectively prevents
- very small/low quality files from being generated. The IJG decoder
- is capable of reading the non-baseline files generated at low quality
- settings when force_baseline is FALSE, but other decoders may not be.
-
-jpeg_set_linear_quality (j_compress_ptr cinfo, int scale_factor,
- boolean force_baseline)
- Same as jpeg_set_quality() except that the generated tables are the
- sample tables given in the JPEC spec section K.1, multiplied by the
- specified scale factor (which is expressed as a percentage; thus
- scale_factor = 100 reproduces the spec's tables). Note that larger
- scale factors give lower quality. This entry point is useful for
- conforming to the Adobe PostScript DCT conventions, but we do not
- recommend linear scaling as a user-visible quality scale otherwise.
- force_baseline again constrains the computed table entries to 1..255.
-
-int jpeg_quality_scaling (int quality)
- Converts a value on the IJG-recommended quality scale to a linear
- scaling percentage. Note that this routine may change or go away
- in future releases --- IJG may choose to adopt a scaling method that
- can't be expressed as a simple scalar multiplier, in which case the
- premise of this routine collapses. Caveat user.
-
-jpeg_default_qtables (j_compress_ptr cinfo, boolean force_baseline)
- Set default quantization tables with linear q_scale_factor[] values
- (see below).
-
-jpeg_add_quant_table (j_compress_ptr cinfo, int which_tbl,
- const unsigned int *basic_table,
- int scale_factor, boolean force_baseline)
- Allows an arbitrary quantization table to be created. which_tbl
- indicates which table slot to fill. basic_table points to an array
- of 64 unsigned ints given in normal array order. These values are
- multiplied by scale_factor/100 and then clamped to the range 1..65535
- (or to 1..255 if force_baseline is TRUE).
- CAUTION: prior to library version 6a, jpeg_add_quant_table expected
- the basic table to be given in JPEG zigzag order. If you need to
- write code that works with either older or newer versions of this
- routine, you must check the library version number. Something like
- "#if JPEG_LIB_VERSION >= 61" is the right test.
-
-jpeg_simple_progression (j_compress_ptr cinfo)
- Generates a default scan script for writing a progressive-JPEG file.
- This is the recommended method of creating a progressive file,
- unless you want to make a custom scan sequence. You must ensure that
- the JPEG color space is set correctly before calling this routine.
-
-
-Compression parameters (cinfo fields) include:
-
-boolean arith_code
- If TRUE, use arithmetic coding.
- If FALSE, use Huffman coding.
-
-int block_size
- Set DCT block size. All N from 1 to 16 are possible.
- Default is 8 (baseline format).
- Larger values produce higher compression,
- smaller values produce higher quality.
- An exact DCT stage is possible with 1 or 2.
- With the default quality of 75 and default Luminance qtable
- the DCT+Quantization stage is lossless for value 1.
- Note that values other than 8 require a SmartScale capable decoder,
- introduced with IJG JPEG 8. Setting the block_size parameter for
- compression works with version 8c and later.
-
-J_DCT_METHOD dct_method
- Selects the algorithm used for the DCT step. Choices are:
- JDCT_ISLOW: slow but accurate integer algorithm
- JDCT_IFAST: faster, less accurate integer method
- JDCT_FLOAT: floating-point method
- JDCT_DEFAULT: default method (normally JDCT_ISLOW)
- JDCT_FASTEST: fastest method (normally JDCT_IFAST)
- The FLOAT method is very slightly more accurate than the ISLOW method,
- but may give different results on different machines due to varying
- roundoff behavior. The integer methods should give the same results
- on all machines. On machines with sufficiently fast FP hardware, the
- floating-point method may also be the fastest. The IFAST method is
- considerably less accurate than the other two; its use is not
- recommended if high quality is a concern. JDCT_DEFAULT and
- JDCT_FASTEST are macros configurable by each installation.
-
-unsigned int scale_num, scale_denom
- Scale the image by the fraction scale_num/scale_denom. Default is
- 1/1, or no scaling. Currently, the supported scaling ratios are
- M/N with all N from 1 to 16, where M is the destination DCT size,
- which is 8 by default (see block_size parameter above).
- (The library design allows for arbitrary scaling ratios but this
- is not likely to be implemented any time soon.)
-
-J_COLOR_SPACE jpeg_color_space
-int num_components
- The JPEG color space and corresponding number of components; see
- "Special color spaces", below, for more info. We recommend using
- jpeg_set_colorspace() if you want to change these.
-
-J_COLOR_TRANSFORM color_transform
- Internal color transform identifier, writes LSE marker if nonzero
- (requires decoder with inverse color transform support, introduced
- with IJG JPEG 9).
- Two values are currently possible: JCT_NONE and JCT_SUBTRACT_GREEN.
- Set this value for lossless RGB application *before* calling
- jpeg_set_colorspace(), because entropy table assignment in
- jpeg_set_colorspace() depends on color_transform.
-
-boolean optimize_coding
- TRUE causes the compressor to compute optimal Huffman coding tables
- for the image. This requires an extra pass over the data and
- therefore costs a good deal of space and time. The default is
- FALSE, which tells the compressor to use the supplied or default
- Huffman tables. In most cases optimal tables save only a few percent
- of file size compared to the default tables. Note that when this is
- TRUE, you need not supply Huffman tables at all, and any you do
- supply will be overwritten.
-
-unsigned int restart_interval
-int restart_in_rows
- To emit restart markers in the JPEG file, set one of these nonzero.
- Set restart_interval to specify the exact interval in MCU blocks.
- Set restart_in_rows to specify the interval in MCU rows. (If
- restart_in_rows is not 0, then restart_interval is set after the
- image width in MCUs is computed.) Defaults are zero (no restarts).
- One restart marker per MCU row is often a good choice.
- NOTE: the overhead of restart markers is higher in grayscale JPEG
- files than in color files, and MUCH higher in progressive JPEGs.
- If you use restarts, you may want to use larger intervals in those
- cases.
-
-const jpeg_scan_info * scan_info
-int num_scans
- By default, scan_info is NULL; this causes the compressor to write a
- single-scan sequential JPEG file. If not NULL, scan_info points to
- an array of scan definition records of length num_scans. The
- compressor will then write a JPEG file having one scan for each scan
- definition record. This is used to generate noninterleaved or
- progressive JPEG files. The library checks that the scan array
- defines a valid JPEG scan sequence. (jpeg_simple_progression creates
- a suitable scan definition array for progressive JPEG.) This is
- discussed further under "Progressive JPEG support".
-
-boolean do_fancy_downsampling
- If TRUE, use direct DCT scaling with DCT size > 8 for downsampling
- of chroma components.
- If FALSE, use only DCT size <= 8 and simple separate downsampling.
- Default is TRUE.
- For better image stability in multiple generation compression cycles
- it is preferable that this value matches the corresponding
- do_fancy_upsampling value in decompression.
-
-int smoothing_factor
- If non-zero, the input image is smoothed; the value should be 1 for
- minimal smoothing to 100 for maximum smoothing. Consult jcsample.c
- for details of the smoothing algorithm. The default is zero.
-
-boolean write_JFIF_header
- If TRUE, a JFIF APP0 marker is emitted. jpeg_set_defaults() and
- jpeg_set_colorspace() set this TRUE if a JFIF-legal JPEG color space
- (ie, YCbCr or grayscale) is selected, otherwise FALSE.
-
-UINT8 JFIF_major_version
-UINT8 JFIF_minor_version
- The version number to be written into the JFIF marker.
- jpeg_set_defaults() initializes the version to 1.01 (major=minor=1).
- You should set it to 1.02 (major=1, minor=2) if you plan to write
- any JFIF 1.02 extension markers.
-
-UINT8 density_unit
-UINT16 X_density
-UINT16 Y_density
- The resolution information to be written into the JFIF marker;
- not used otherwise. density_unit may be 0 for unknown,
- 1 for dots/inch, or 2 for dots/cm. The default values are 0,1,1
- indicating square pixels of unknown size.
-
-boolean write_Adobe_marker
- If TRUE, an Adobe APP14 marker is emitted. jpeg_set_defaults() and
- jpeg_set_colorspace() set this TRUE if JPEG color space RGB, CMYK,
- or YCCK is selected, otherwise FALSE. It is generally a bad idea
- to set both write_JFIF_header and write_Adobe_marker. In fact,
- you probably shouldn't change the default settings at all --- the
- default behavior ensures that the JPEG file's color space can be
- recognized by the decoder.
-
-JQUANT_TBL * quant_tbl_ptrs[NUM_QUANT_TBLS]
- Pointers to coefficient quantization tables, one per table slot,
- or NULL if no table is defined for a slot. Usually these should
- be set via one of the above helper routines; jpeg_add_quant_table()
- is general enough to define any quantization table. The other
- routines will set up table slot 0 for luminance quality and table
- slot 1 for chrominance.
-
-int q_scale_factor[NUM_QUANT_TBLS]
- Linear quantization scaling factors (percentage, initialized 100)
- for use with jpeg_default_qtables().
- See rdswitch.c and cjpeg.c for an example of usage.
- Note that the q_scale_factor[] fields are the "linear" scales, so you
- have to convert from user-defined ratings via jpeg_quality_scaling().
- Here is an example code which corresponds to cjpeg -quality 90,70:
-
- jpeg_set_defaults(cinfo);
-
- /* Set luminance quality 90. */
- cinfo->q_scale_factor[0] = jpeg_quality_scaling(90);
- /* Set chrominance quality 70. */
- cinfo->q_scale_factor[1] = jpeg_quality_scaling(70);
-
- jpeg_default_qtables(cinfo, force_baseline);
-
- CAUTION: You must also set 1x1 subsampling for efficient separate
- color quality selection, since the default value used by library
- is 2x2:
-
- cinfo->comp_info[0].v_samp_factor = 1;
- cinfo->comp_info[0].h_samp_factor = 1;
-
-JHUFF_TBL * dc_huff_tbl_ptrs[NUM_HUFF_TBLS]
-JHUFF_TBL * ac_huff_tbl_ptrs[NUM_HUFF_TBLS]
- Pointers to Huffman coding tables, one per table slot, or NULL if
- no table is defined for a slot. Slots 0 and 1 are filled with the
- JPEG sample tables by jpeg_set_defaults(). If you need to allocate
- more table structures, jpeg_alloc_huff_table() may be used.
- Note that optimal Huffman tables can be computed for an image
- by setting optimize_coding, as discussed above; there's seldom
- any need to mess with providing your own Huffman tables.
-
-
-The actual dimensions of the JPEG image that will be written to the file are
-given by the following fields. These are computed from the input image
-dimensions and the compression parameters by jpeg_start_compress(). You can
-also call jpeg_calc_jpeg_dimensions() to obtain the values that will result
-from the current parameter settings. This can be useful if you are trying
-to pick a scaling ratio that will get close to a desired target size.
-
-JDIMENSION jpeg_width Actual dimensions of output image.
-JDIMENSION jpeg_height
-
-
-Per-component parameters are stored in the struct cinfo.comp_info[i] for
-component number i. Note that components here refer to components of the
-JPEG color space, *not* the source image color space. A suitably large
-comp_info[] array is allocated by jpeg_set_defaults(); if you choose not
-to use that routine, it's up to you to allocate the array.
-
-int component_id
- The one-byte identifier code to be recorded in the JPEG file for
- this component. For the standard color spaces, we recommend you
- leave the default values alone.
-
-int h_samp_factor
-int v_samp_factor
- Horizontal and vertical sampling factors for the component; must
- be 1..4 according to the JPEG standard. Note that larger sampling
- factors indicate a higher-resolution component; many people find
- this behavior quite unintuitive. The default values are 2,2 for
- luminance components and 1,1 for chrominance components, except
- for grayscale where 1,1 is used.
-
-int quant_tbl_no
- Quantization table number for component. The default value is
- 0 for luminance components and 1 for chrominance components.
-
-int dc_tbl_no
-int ac_tbl_no
- DC and AC entropy coding table numbers. The default values are
- 0 for luminance components and 1 for chrominance components.
-
-int component_index
- Must equal the component's index in comp_info[]. (Beginning in
- release v6, the compressor library will fill this in automatically;
- you don't have to.)
-
-
-Decompression parameter selection
----------------------------------
-
-Decompression parameter selection is somewhat simpler than compression
-parameter selection, since all of the JPEG internal parameters are
-recorded in the source file and need not be supplied by the application.
-(Unless you are working with abbreviated files, in which case see
-"Abbreviated datastreams", below.) Decompression parameters control
-the postprocessing done on the image to deliver it in a format suitable
-for the application's use. Many of the parameters control speed/quality
-tradeoffs, in which faster decompression may be obtained at the price of
-a poorer-quality image. The defaults select the highest quality (slowest)
-processing.
-
-The following fields in the JPEG object are set by jpeg_read_header() and
-may be useful to the application in choosing decompression parameters:
-
-JDIMENSION image_width Width and height of image
-JDIMENSION image_height
-int num_components Number of color components
-J_COLOR_SPACE jpeg_color_space Colorspace of image
-boolean saw_JFIF_marker TRUE if a JFIF APP0 marker was seen
- UINT8 JFIF_major_version Version information from JFIF marker
- UINT8 JFIF_minor_version
- UINT8 density_unit Resolution data from JFIF marker
- UINT16 X_density
- UINT16 Y_density
-boolean saw_Adobe_marker TRUE if an Adobe APP14 marker was seen
- UINT8 Adobe_transform Color transform code from Adobe marker
-
-The JPEG color space, unfortunately, is something of a guess since the JPEG
-standard proper does not provide a way to record it. In practice most files
-adhere to the JFIF or Adobe conventions, and the decoder will recognize these
-correctly. See "Special color spaces", below, for more info.
-
-
-The decompression parameters that determine the basic properties of the
-returned image are:
-
-J_COLOR_SPACE out_color_space
- Output color space. jpeg_read_header() sets an appropriate default
- based on jpeg_color_space; typically it will be RGB or grayscale.
- The application can change this field to request output in a different
- colorspace. For example, set it to JCS_GRAYSCALE to get grayscale
- output from a color file. (This is useful for previewing: grayscale
- output is faster than full color since the color components need not
- be processed.) Note that not all possible color space transforms are
- currently implemented; you may need to extend jdcolor.c if you want an
- unusual conversion.
-
-unsigned int scale_num, scale_denom
- Scale the image by the fraction scale_num/scale_denom. Currently,
- the supported scaling ratios are M/N with all M from 1 to 16, where
- N is the source DCT size, which is 8 for baseline JPEG. (The library
- design allows for arbitrary scaling ratios but this is not likely
- to be implemented any time soon.) The values are initialized by
- jpeg_read_header() with the source DCT size. For baseline JPEG
- this is 8/8. If you change only the scale_num value while leaving
- the other unchanged, then this specifies the DCT scaled size to be
- applied on the given input. For baseline JPEG this is equivalent
- to M/8 scaling, since the source DCT size for baseline JPEG is 8.
- Smaller scaling ratios permit significantly faster decoding since
- fewer pixels need be processed and a simpler IDCT method can be used.
-
-boolean quantize_colors
- If set TRUE, colormapped output will be delivered. Default is FALSE,
- meaning that full-color output will be delivered.
-
-The next three parameters are relevant only if quantize_colors is TRUE.
-
-int desired_number_of_colors
- Maximum number of colors to use in generating a library-supplied color
- map (the actual number of colors is returned in a different field).
- Default 256. Ignored when the application supplies its own color map.
-
-boolean two_pass_quantize
- If TRUE, an extra pass over the image is made to select a custom color
- map for the image. This usually looks a lot better than the one-size-
- fits-all colormap that is used otherwise. Default is TRUE. Ignored
- when the application supplies its own color map.
-
-J_DITHER_MODE dither_mode
- Selects color dithering method. Supported values are:
- JDITHER_NONE no dithering: fast, very low quality
- JDITHER_ORDERED ordered dither: moderate speed and quality
- JDITHER_FS Floyd-Steinberg dither: slow, high quality
- Default is JDITHER_FS. (At present, ordered dither is implemented
- only in the single-pass, standard-colormap case. If you ask for
- ordered dither when two_pass_quantize is TRUE or when you supply
- an external color map, you'll get F-S dithering.)
-
-When quantize_colors is TRUE, the target color map is described by the next
-two fields. colormap is set to NULL by jpeg_read_header(). The application
-can supply a color map by setting colormap non-NULL and setting
-actual_number_of_colors to the map size. Otherwise, jpeg_start_decompress()
-selects a suitable color map and sets these two fields itself.
-[Implementation restriction: at present, an externally supplied colormap is
-only accepted for 3-component output color spaces.]
-
-JSAMPARRAY colormap
- The color map, represented as a 2-D pixel array of out_color_components
- rows and actual_number_of_colors columns. Ignored if not quantizing.
- CAUTION: if the JPEG library creates its own colormap, the storage
- pointed to by this field is released by jpeg_finish_decompress().
- Copy the colormap somewhere else first, if you want to save it.
-
-int actual_number_of_colors
- The number of colors in the color map.
-
-Additional decompression parameters that the application may set include:
-
-J_DCT_METHOD dct_method
- Selects the algorithm used for the DCT step. Choices are the same
- as described above for compression.
-
-boolean do_fancy_upsampling
- If TRUE, use direct DCT scaling with DCT size > 8 for upsampling
- of chroma components.
- If FALSE, use only DCT size <= 8 and simple separate upsampling.
- Default is TRUE.
- For better image stability in multiple generation compression cycles
- it is preferable that this value matches the corresponding
- do_fancy_downsampling value in compression.
-
-boolean do_block_smoothing
- If TRUE, interblock smoothing is applied in early stages of decoding
- progressive JPEG files; if FALSE, not. Default is TRUE. Early
- progression stages look "fuzzy" with smoothing, "blocky" without.
- In any case, block smoothing ceases to be applied after the first few
- AC coefficients are known to full accuracy, so it is relevant only
- when using buffered-image mode for progressive images.
-
-boolean enable_1pass_quant
-boolean enable_external_quant
-boolean enable_2pass_quant
- These are significant only in buffered-image mode, which is
- described in its own section below.
-
-
-The output image dimensions are given by the following fields. These are
-computed from the source image dimensions and the decompression parameters
-by jpeg_start_decompress(). You can also call jpeg_calc_output_dimensions()
-to obtain the values that will result from the current parameter settings.
-This can be useful if you are trying to pick a scaling ratio that will get
-close to a desired target size. It's also important if you are using the
-JPEG library's memory manager to allocate output buffer space, because you
-are supposed to request such buffers *before* jpeg_start_decompress().
-
-JDIMENSION output_width Actual dimensions of output image.
-JDIMENSION output_height
-int out_color_components Number of color components in out_color_space.
-int output_components Number of color components returned.
-int rec_outbuf_height Recommended height of scanline buffer.
-
-When quantizing colors, output_components is 1, indicating a single color map
-index per pixel. Otherwise it equals out_color_components. The output arrays
-are required to be output_width * output_components JSAMPLEs wide.
-
-rec_outbuf_height is the recommended minimum height (in scanlines) of the
-buffer passed to jpeg_read_scanlines(). If the buffer is smaller, the
-library will still work, but time will be wasted due to unnecessary data
-copying. In high-quality modes, rec_outbuf_height is always 1, but some
-faster, lower-quality modes set it to larger values (typically 2 to 4).
-If you are going to ask for a high-speed processing mode, you may as well
-go to the trouble of honoring rec_outbuf_height so as to avoid data copying.
-(An output buffer larger than rec_outbuf_height lines is OK, but won't
-provide any material speed improvement over that height.)
-
-
-Special color spaces
---------------------
-
-The JPEG standard itself is "color blind" and doesn't specify any particular
-color space. It is customary to convert color data to a luminance/chrominance
-color space before compressing, since this permits greater compression. The
-existing JPEG file interchange format standards specify YCbCr or GRAYSCALE
-data (JFIF version 1), GRAYSCALE, RGB, YCbCr, CMYK, or YCCK (Adobe), or BG_RGB
-or BG_YCC (big gamut color spaces, JFIF version 2). For special applications
-such as multispectral images, other color spaces can be used,
-but it must be understood that such files will be unportable.
-
-The JPEG library can handle the most common colorspace conversions (namely
-RGB <=> YCbCr and CMYK <=> YCCK). It can also deal with data of an unknown
-color space, passing it through without conversion. If you deal extensively
-with an unusual color space, you can easily extend the library to understand
-additional color spaces and perform appropriate conversions.
-
-For compression, the source data's color space is specified by field
-in_color_space. This is transformed to the JPEG file's color space given
-by jpeg_color_space. jpeg_set_defaults() chooses a reasonable JPEG color
-space depending on in_color_space, but you can override this by calling
-jpeg_set_colorspace(). Of course you must select a supported transformation.
-jccolor.c currently supports the following transformations:
- RGB => YCbCr
- RGB => GRAYSCALE
- RGB => BG_YCC
- YCbCr => GRAYSCALE
- YCbCr => BG_YCC
- CMYK => YCCK
-plus the null transforms: GRAYSCALE => GRAYSCALE, RGB => RGB,
-BG_RGB => BG_RGB, YCbCr => YCbCr, BG_YCC => BG_YCC, CMYK => CMYK,
-YCCK => YCCK, and UNKNOWN => UNKNOWN.
-
-The file interchange format standards (JFIF and Adobe) specify APPn markers
-that indicate the color space of the JPEG file. It is important to ensure
-that these are written correctly, or omitted if the JPEG file's color space
-is not one of the ones supported by the interchange standards.
-jpeg_set_colorspace() will set the compression parameters to include or omit
-the APPn markers properly, so long as it is told the truth about the JPEG
-color space. For example, if you are writing some random 3-component color
-space without conversion, don't try to fake out the library by setting
-in_color_space and jpeg_color_space to JCS_YCbCr; use JCS_UNKNOWN.
-You may want to write an APPn marker of your own devising to identify
-the colorspace --- see "Special markers", below.
-
-When told that the color space is UNKNOWN, the library will default to using
-luminance-quality compression parameters for all color components. You may
-well want to change these parameters. See the source code for
-jpeg_set_colorspace(), in jcparam.c, for details.
-
-For decompression, the JPEG file's color space is given in jpeg_color_space,
-and this is transformed to the output color space out_color_space.
-jpeg_read_header's setting of jpeg_color_space can be relied on if the file
-conforms to JFIF or Adobe conventions, but otherwise it is no better than a
-guess. If you know the JPEG file's color space for certain, you can override
-jpeg_read_header's guess by setting jpeg_color_space. jpeg_read_header also
-selects a default output color space based on (its guess of) jpeg_color_space;
-set out_color_space to override this. Again, you must select a supported
-transformation. jdcolor.c currently supports
- YCbCr => RGB
- YCbCr => GRAYSCALE
- BG_YCC => RGB
- BG_YCC => GRAYSCALE
- RGB => GRAYSCALE
- GRAYSCALE => RGB
- YCCK => CMYK
-as well as the null transforms. (Since GRAYSCALE=>RGB is provided, an
-application can force grayscale JPEGs to look like color JPEGs if it only
-wants to handle one case.)
-
-The two-pass color quantizer, jquant2.c, is specialized to handle RGB data
-(it weights distances appropriately for RGB colors). You'll need to modify
-the code if you want to use it for non-RGB output color spaces. Note that
-jquant2.c is used to map to an application-supplied colormap as well as for
-the normal two-pass colormap selection process.
-
-CAUTION: it appears that Adobe Photoshop writes inverted data in CMYK JPEG
-files: 0 represents 100% ink coverage, rather than 0% ink as you'd expect.
-This is arguably a bug in Photoshop, but if you need to work with Photoshop
-CMYK files, you will have to deal with it in your application. We cannot
-"fix" this in the library by inverting the data during the CMYK<=>YCCK
-transform, because that would break other applications, notably Ghostscript.
-Photoshop versions prior to 3.0 write EPS files containing JPEG-encoded CMYK
-data in the same inverted-YCCK representation used in bare JPEG files, but
-the surrounding PostScript code performs an inversion using the PS image
-operator. I am told that Photoshop 3.0 will write uninverted YCCK in
-EPS/JPEG files, and will omit the PS-level inversion. (But the data
-polarity used in bare JPEG files will not change in 3.0.) In either case,
-the JPEG library must not invert the data itself, or else Ghostscript would
-read these EPS files incorrectly.
-
-
-Error handling
---------------
-
-When the default error handler is used, any error detected inside the JPEG
-routines will cause a message to be printed on stderr, followed by exit().
-You can supply your own error handling routines to override this behavior
-and to control the treatment of nonfatal warnings and trace/debug messages.
-The file example.c illustrates the most common case, which is to have the
-application regain control after an error rather than exiting.
-
-The JPEG library never writes any message directly; it always goes through
-the error handling routines. Three classes of messages are recognized:
- * Fatal errors: the library cannot continue.
- * Warnings: the library can continue, but the data is corrupt, and a
- damaged output image is likely to result.
- * Trace/informational messages. These come with a trace level indicating
- the importance of the message; you can control the verbosity of the
- program by adjusting the maximum trace level that will be displayed.
-
-You may, if you wish, simply replace the entire JPEG error handling module
-(jerror.c) with your own code. However, you can avoid code duplication by
-only replacing some of the routines depending on the behavior you need.
-This is accomplished by calling jpeg_std_error() as usual, but then overriding
-some of the method pointers in the jpeg_error_mgr struct, as illustrated by
-example.c.
-
-All of the error handling routines will receive a pointer to the JPEG object
-(a j_common_ptr which points to either a jpeg_compress_struct or a
-jpeg_decompress_struct; if you need to tell which, test the is_decompressor
-field). This struct includes a pointer to the error manager struct in its
-"err" field. Frequently, custom error handler routines will need to access
-additional data which is not known to the JPEG library or the standard error
-handler. The most convenient way to do this is to embed either the JPEG
-object or the jpeg_error_mgr struct in a larger structure that contains
-additional fields; then casting the passed pointer provides access to the
-additional fields. Again, see example.c for one way to do it. (Beginning
-with IJG version 6b, there is also a void pointer "client_data" in each
-JPEG object, which the application can also use to find related data.
-The library does not touch client_data at all.)
-
-The individual methods that you might wish to override are:
-
-error_exit (j_common_ptr cinfo)
- Receives control for a fatal error. Information sufficient to
- generate the error message has been stored in cinfo->err; call
- output_message to display it. Control must NOT return to the caller;
- generally this routine will exit() or longjmp() somewhere.
- Typically you would override this routine to get rid of the exit()
- default behavior. Note that if you continue processing, you should
- clean up the JPEG object with jpeg_abort() or jpeg_destroy().
-
-output_message (j_common_ptr cinfo)
- Actual output of any JPEG message. Override this to send messages
- somewhere other than stderr. Note that this method does not know
- how to generate a message, only where to send it.
-
-format_message (j_common_ptr cinfo, char * buffer)
- Constructs a readable error message string based on the error info
- stored in cinfo->err. This method is called by output_message. Few
- applications should need to override this method. One possible
- reason for doing so is to implement dynamic switching of error message
- language.
-
-emit_message (j_common_ptr cinfo, int msg_level)
- Decide whether or not to emit a warning or trace message; if so,
- calls output_message. The main reason for overriding this method
- would be to abort on warnings. msg_level is -1 for warnings,
- 0 and up for trace messages.
-
-Only error_exit() and emit_message() are called from the rest of the JPEG
-library; the other two are internal to the error handler.
-
-The actual message texts are stored in an array of strings which is pointed to
-by the field err->jpeg_message_table. The messages are numbered from 0 to
-err->last_jpeg_message, and it is these code numbers that are used in the
-JPEG library code. You could replace the message texts (for instance, with
-messages in French or German) by changing the message table pointer. See
-jerror.h for the default texts. CAUTION: this table will almost certainly
-change or grow from one library version to the next.
-
-It may be useful for an application to add its own message texts that are
-handled by the same mechanism. The error handler supports a second "add-on"
-message table for this purpose. To define an addon table, set the pointer
-err->addon_message_table and the message numbers err->first_addon_message and
-err->last_addon_message. If you number the addon messages beginning at 1000
-or so, you won't have to worry about conflicts with the library's built-in
-messages. See the sample applications cjpeg/djpeg for an example of using
-addon messages (the addon messages are defined in cderror.h).
-
-Actual invocation of the error handler is done via macros defined in jerror.h:
- ERREXITn(...) for fatal errors
- WARNMSn(...) for corrupt-data warnings
- TRACEMSn(...) for trace and informational messages.
-These macros store the message code and any additional parameters into the
-error handler struct, then invoke the error_exit() or emit_message() method.
-The variants of each macro are for varying numbers of additional parameters.
-The additional parameters are inserted into the generated message using
-standard printf() format codes.
-
-See jerror.h and jerror.c for further details.
-
-
-Compressed data handling (source and destination managers)
-----------------------------------------------------------
-
-The JPEG compression library sends its compressed data to a "destination
-manager" module. The default destination manager just writes the data to a
-memory buffer or to a stdio stream, but you can provide your own manager to
-do something else. Similarly, the decompression library calls a "source
-manager" to obtain the compressed data; you can provide your own source
-manager if you want the data to come from somewhere other than a memory
-buffer or a stdio stream.
-
-In both cases, compressed data is processed a bufferload at a time: the
-destination or source manager provides a work buffer, and the library invokes
-the manager only when the buffer is filled or emptied. (You could define a
-one-character buffer to force the manager to be invoked for each byte, but
-that would be rather inefficient.) The buffer's size and location are
-controlled by the manager, not by the library. For example, the memory
-source manager just makes the buffer pointer and length point to the original
-data in memory. In this case the buffer-reload procedure will be invoked
-only if the decompressor ran off the end of the datastream, which would
-indicate an erroneous datastream.
-
-The work buffer is defined as an array of datatype JOCTET, which is generally
-"char" or "unsigned char". On a machine where char is not exactly 8 bits
-wide, you must define JOCTET as a wider data type and then modify the data
-source and destination modules to transcribe the work arrays into 8-bit units
-on external storage.
-
-A data destination manager struct contains a pointer and count defining the
-next byte to write in the work buffer and the remaining free space:
-
- JOCTET * next_output_byte; /* => next byte to write in buffer */
- size_t free_in_buffer; /* # of byte spaces remaining in buffer */
-
-The library increments the pointer and decrements the count until the buffer
-is filled. The manager's empty_output_buffer method must reset the pointer
-and count. The manager is expected to remember the buffer's starting address
-and total size in private fields not visible to the library.
-
-A data destination manager provides three methods:
-
-init_destination (j_compress_ptr cinfo)
- Initialize destination. This is called by jpeg_start_compress()
- before any data is actually written. It must initialize
- next_output_byte and free_in_buffer. free_in_buffer must be
- initialized to a positive value.
-
-empty_output_buffer (j_compress_ptr cinfo)
- This is called whenever the buffer has filled (free_in_buffer
- reaches zero). In typical applications, it should write out the
- *entire* buffer (use the saved start address and buffer length;
- ignore the current state of next_output_byte and free_in_buffer).
- Then reset the pointer & count to the start of the buffer, and
- return TRUE indicating that the buffer has been dumped.
- free_in_buffer must be set to a positive value when TRUE is
- returned. A FALSE return should only be used when I/O suspension is
- desired (this operating mode is discussed in the next section).
-
-term_destination (j_compress_ptr cinfo)
- Terminate destination --- called by jpeg_finish_compress() after all
- data has been written. In most applications, this must flush any
- data remaining in the buffer. Use either next_output_byte or
- free_in_buffer to determine how much data is in the buffer.
-
-term_destination() is NOT called by jpeg_abort() or jpeg_destroy(). If you
-want the destination manager to be cleaned up during an abort, you must do it
-yourself.
-
-You will also need code to create a jpeg_destination_mgr struct, fill in its
-method pointers, and insert a pointer to the struct into the "dest" field of
-the JPEG compression object. This can be done in-line in your setup code if
-you like, but it's probably cleaner to provide a separate routine similar to
-the jpeg_stdio_dest() or jpeg_mem_dest() routines of the supplied destination
-managers.
-
-Decompression source managers follow a parallel design, but with some
-additional frammishes. The source manager struct contains a pointer and count
-defining the next byte to read from the work buffer and the number of bytes
-remaining:
-
- const JOCTET * next_input_byte; /* => next byte to read from buffer */
- size_t bytes_in_buffer; /* # of bytes remaining in buffer */
-
-The library increments the pointer and decrements the count until the buffer
-is emptied. The manager's fill_input_buffer method must reset the pointer and
-count. In most applications, the manager must remember the buffer's starting
-address and total size in private fields not visible to the library.
-
-A data source manager provides five methods:
-
-init_source (j_decompress_ptr cinfo)
- Initialize source. This is called by jpeg_read_header() before any
- data is actually read. Unlike init_destination(), it may leave
- bytes_in_buffer set to 0 (in which case a fill_input_buffer() call
- will occur immediately).
-
-fill_input_buffer (j_decompress_ptr cinfo)
- This is called whenever bytes_in_buffer has reached zero and more
- data is wanted. In typical applications, it should read fresh data
- into the buffer (ignoring the current state of next_input_byte and
- bytes_in_buffer), reset the pointer & count to the start of the
- buffer, and return TRUE indicating that the buffer has been reloaded.
- It is not necessary to fill the buffer entirely, only to obtain at
- least one more byte. bytes_in_buffer MUST be set to a positive value
- if TRUE is returned. A FALSE return should only be used when I/O
- suspension is desired (this mode is discussed in the next section).
-
-skip_input_data (j_decompress_ptr cinfo, long num_bytes)
- Skip num_bytes worth of data. The buffer pointer and count should
- be advanced over num_bytes input bytes, refilling the buffer as
- needed. This is used to skip over a potentially large amount of
- uninteresting data (such as an APPn marker). In some applications
- it may be possible to optimize away the reading of the skipped data,
- but it's not clear that being smart is worth much trouble; large
- skips are uncommon. bytes_in_buffer may be zero on return.
- A zero or negative skip count should be treated as a no-op.
-
-resync_to_restart (j_decompress_ptr cinfo, int desired)
- This routine is called only when the decompressor has failed to find
- a restart (RSTn) marker where one is expected. Its mission is to
- find a suitable point for resuming decompression. For most
- applications, we recommend that you just use the default resync
- procedure, jpeg_resync_to_restart(). However, if you are able to back
- up in the input data stream, or if you have a-priori knowledge about
- the likely location of restart markers, you may be able to do better.
- Read the read_restart_marker() and jpeg_resync_to_restart() routines
- in jdmarker.c if you think you'd like to implement your own resync
- procedure.
-
-term_source (j_decompress_ptr cinfo)
- Terminate source --- called by jpeg_finish_decompress() after all
- data has been read. Often a no-op.
-
-For both fill_input_buffer() and skip_input_data(), there is no such thing
-as an EOF return. If the end of the file has been reached, the routine has
-a choice of exiting via ERREXIT() or inserting fake data into the buffer.
-In most cases, generating a warning message and inserting a fake EOI marker
-is the best course of action --- this will allow the decompressor to output
-however much of the image is there. In pathological cases, the decompressor
-may swallow the EOI and again demand data ... just keep feeding it fake EOIs.
-jdatasrc.c illustrates the recommended error recovery behavior.
-
-term_source() is NOT called by jpeg_abort() or jpeg_destroy(). If you want
-the source manager to be cleaned up during an abort, you must do it yourself.
-
-You will also need code to create a jpeg_source_mgr struct, fill in its method
-pointers, and insert a pointer to the struct into the "src" field of the JPEG
-decompression object. This can be done in-line in your setup code if you
-like, but it's probably cleaner to provide a separate routine similar to the
-jpeg_stdio_src() or jpeg_mem_src() routines of the supplied source managers.
-
-For more information, consult the memory and stdio source and destination
-managers in jdatasrc.c and jdatadst.c.
-
-
-I/O suspension
---------------
-
-Some applications need to use the JPEG library as an incremental memory-to-
-memory filter: when the compressed data buffer is filled or emptied, they want
-control to return to the outer loop, rather than expecting that the buffer can
-be emptied or reloaded within the data source/destination manager subroutine.
-The library supports this need by providing an "I/O suspension" mode, which we
-describe in this section.
-
-The I/O suspension mode is not a panacea: nothing is guaranteed about the
-maximum amount of time spent in any one call to the library, so it will not
-eliminate response-time problems in single-threaded applications. If you
-need guaranteed response time, we suggest you "bite the bullet" and implement
-a real multi-tasking capability.
-
-To use I/O suspension, cooperation is needed between the calling application
-and the data source or destination manager; you will always need a custom
-source/destination manager. (Please read the previous section if you haven't
-already.) The basic idea is that the empty_output_buffer() or
-fill_input_buffer() routine is a no-op, merely returning FALSE to indicate
-that it has done nothing. Upon seeing this, the JPEG library suspends
-operation and returns to its caller. The surrounding application is
-responsible for emptying or refilling the work buffer before calling the
-JPEG library again.
-
-Compression suspension:
-
-For compression suspension, use an empty_output_buffer() routine that returns
-FALSE; typically it will not do anything else. This will cause the
-compressor to return to the caller of jpeg_write_scanlines(), with the return
-value indicating that not all the supplied scanlines have been accepted.
-The application must make more room in the output buffer, adjust the output
-buffer pointer/count appropriately, and then call jpeg_write_scanlines()
-again, pointing to the first unconsumed scanline.
-
-When forced to suspend, the compressor will backtrack to a convenient stopping
-point (usually the start of the current MCU); it will regenerate some output
-data when restarted. Therefore, although empty_output_buffer() is only
-called when the buffer is filled, you should NOT write out the entire buffer
-after a suspension. Write only the data up to the current position of
-next_output_byte/free_in_buffer. The data beyond that point will be
-regenerated after resumption.
-
-Because of the backtracking behavior, a good-size output buffer is essential
-for efficiency; you don't want the compressor to suspend often. (In fact, an
-overly small buffer could lead to infinite looping, if a single MCU required
-more data than would fit in the buffer.) We recommend a buffer of at least
-several Kbytes. You may want to insert explicit code to ensure that you don't
-call jpeg_write_scanlines() unless there is a reasonable amount of space in
-the output buffer; in other words, flush the buffer before trying to compress
-more data.
-
-The compressor does not allow suspension while it is trying to write JPEG
-markers at the beginning and end of the file. This means that:
- * At the beginning of a compression operation, there must be enough free
- space in the output buffer to hold the header markers (typically 600 or
- so bytes). The recommended buffer size is bigger than this anyway, so
- this is not a problem as long as you start with an empty buffer. However,
- this restriction might catch you if you insert large special markers, such
- as a JFIF thumbnail image, without flushing the buffer afterwards.
- * When you call jpeg_finish_compress(), there must be enough space in the
- output buffer to emit any buffered data and the final EOI marker. In the
- current implementation, half a dozen bytes should suffice for this, but
- for safety's sake we recommend ensuring that at least 100 bytes are free
- before calling jpeg_finish_compress().
-
-A more significant restriction is that jpeg_finish_compress() cannot suspend.
-This means you cannot use suspension with multi-pass operating modes, namely
-Huffman code optimization and multiple-scan output. Those modes write the
-whole file during jpeg_finish_compress(), which will certainly result in
-buffer overrun. (Note that this restriction applies only to compression,
-not decompression. The decompressor supports input suspension in all of its
-operating modes.)
-
-Decompression suspension:
-
-For decompression suspension, use a fill_input_buffer() routine that simply
-returns FALSE (except perhaps during error recovery, as discussed below).
-This will cause the decompressor to return to its caller with an indication
-that suspension has occurred. This can happen at four places:
- * jpeg_read_header(): will return JPEG_SUSPENDED.
- * jpeg_start_decompress(): will return FALSE, rather than its usual TRUE.
- * jpeg_read_scanlines(): will return the number of scanlines already
- completed (possibly 0).
- * jpeg_finish_decompress(): will return FALSE, rather than its usual TRUE.
-The surrounding application must recognize these cases, load more data into
-the input buffer, and repeat the call. In the case of jpeg_read_scanlines(),
-increment the passed pointers past any scanlines successfully read.
-
-Just as with compression, the decompressor will typically backtrack to a
-convenient restart point before suspending. When fill_input_buffer() is
-called, next_input_byte/bytes_in_buffer point to the current restart point,
-which is where the decompressor will backtrack to if FALSE is returned.
-The data beyond that position must NOT be discarded if you suspend; it needs
-to be re-read upon resumption. In most implementations, you'll need to shift
-this data down to the start of your work buffer and then load more data after
-it. Again, this behavior means that a several-Kbyte work buffer is essential
-for decent performance; furthermore, you should load a reasonable amount of
-new data before resuming decompression. (If you loaded, say, only one new
-byte each time around, you could waste a LOT of cycles.)
-
-The skip_input_data() source manager routine requires special care in a
-suspension scenario. This routine is NOT granted the ability to suspend the
-decompressor; it can decrement bytes_in_buffer to zero, but no more. If the
-requested skip distance exceeds the amount of data currently in the input
-buffer, then skip_input_data() must set bytes_in_buffer to zero and record the
-additional skip distance somewhere else. The decompressor will immediately
-call fill_input_buffer(), which should return FALSE, which will cause a
-suspension return. The surrounding application must then arrange to discard
-the recorded number of bytes before it resumes loading the input buffer.
-(Yes, this design is rather baroque, but it avoids complexity in the far more
-common case where a non-suspending source manager is used.)
-
-If the input data has been exhausted, we recommend that you emit a warning
-and insert dummy EOI markers just as a non-suspending data source manager
-would do. This can be handled either in the surrounding application logic or
-within fill_input_buffer(); the latter is probably more efficient. If
-fill_input_buffer() knows that no more data is available, it can set the
-pointer/count to point to a dummy EOI marker and then return TRUE just as
-though it had read more data in a non-suspending situation.
-
-The decompressor does not attempt to suspend within standard JPEG markers;
-instead it will backtrack to the start of the marker and reprocess the whole
-marker next time. Hence the input buffer must be large enough to hold the
-longest standard marker in the file. Standard JPEG markers should normally
-not exceed a few hundred bytes each (DHT tables are typically the longest).
-We recommend at least a 2K buffer for performance reasons, which is much
-larger than any correct marker is likely to be. For robustness against
-damaged marker length counts, you may wish to insert a test in your
-application for the case that the input buffer is completely full and yet
-the decoder has suspended without consuming any data --- otherwise, if this
-situation did occur, it would lead to an endless loop. (The library can't
-provide this test since it has no idea whether "the buffer is full", or
-even whether there is a fixed-size input buffer.)
-
-The input buffer would need to be 64K to allow for arbitrary COM or APPn
-markers, but these are handled specially: they are either saved into allocated
-memory, or skipped over by calling skip_input_data(). In the former case,
-suspension is handled correctly, and in the latter case, the problem of
-buffer overrun is placed on skip_input_data's shoulders, as explained above.
-Note that if you provide your own marker handling routine for large markers,
-you should consider how to deal with buffer overflow.
-
-Multiple-buffer management:
-
-In some applications it is desirable to store the compressed data in a linked
-list of buffer areas, so as to avoid data copying. This can be handled by
-having empty_output_buffer() or fill_input_buffer() set the pointer and count
-to reference the next available buffer; FALSE is returned only if no more
-buffers are available. Although seemingly straightforward, there is a
-pitfall in this approach: the backtrack that occurs when FALSE is returned
-could back up into an earlier buffer. For example, when fill_input_buffer()
-is called, the current pointer & count indicate the backtrack restart point.
-Since fill_input_buffer() will set the pointer and count to refer to a new
-buffer, the restart position must be saved somewhere else. Suppose a second
-call to fill_input_buffer() occurs in the same library call, and no
-additional input data is available, so fill_input_buffer must return FALSE.
-If the JPEG library has not moved the pointer/count forward in the current
-buffer, then *the correct restart point is the saved position in the prior
-buffer*. Prior buffers may be discarded only after the library establishes
-a restart point within a later buffer. Similar remarks apply for output into
-a chain of buffers.
-
-The library will never attempt to backtrack over a skip_input_data() call,
-so any skipped data can be permanently discarded. You still have to deal
-with the case of skipping not-yet-received data, however.
-
-It's much simpler to use only a single buffer; when fill_input_buffer() is
-called, move any unconsumed data (beyond the current pointer/count) down to
-the beginning of this buffer and then load new data into the remaining buffer
-space. This approach requires a little more data copying but is far easier
-to get right.
-
-
-Progressive JPEG support
-------------------------
-
-Progressive JPEG rearranges the stored data into a series of scans of
-increasing quality. In situations where a JPEG file is transmitted across a
-slow communications link, a decoder can generate a low-quality image very
-quickly from the first scan, then gradually improve the displayed quality as
-more scans are received. The final image after all scans are complete is
-identical to that of a regular (sequential) JPEG file of the same quality
-setting. Progressive JPEG files are often slightly smaller than equivalent
-sequential JPEG files, but the possibility of incremental display is the main
-reason for using progressive JPEG.
-
-The IJG encoder library generates progressive JPEG files when given a
-suitable "scan script" defining how to divide the data into scans.
-Creation of progressive JPEG files is otherwise transparent to the encoder.
-Progressive JPEG files can also be read transparently by the decoder library.
-If the decoding application simply uses the library as defined above, it
-will receive a final decoded image without any indication that the file was
-progressive. Of course, this approach does not allow incremental display.
-To perform incremental display, an application needs to use the decoder
-library's "buffered-image" mode, in which it receives a decoded image
-multiple times.
-
-Each displayed scan requires about as much work to decode as a full JPEG
-image of the same size, so the decoder must be fairly fast in relation to the
-data transmission rate in order to make incremental display useful. However,
-it is possible to skip displaying the image and simply add the incoming bits
-to the decoder's coefficient buffer. This is fast because only Huffman
-decoding need be done, not IDCT, upsampling, colorspace conversion, etc.
-The IJG decoder library allows the application to switch dynamically between
-displaying the image and simply absorbing the incoming bits. A properly
-coded application can automatically adapt the number of display passes to
-suit the time available as the image is received. Also, a final
-higher-quality display cycle can be performed from the buffered data after
-the end of the file is reached.
-
-Progressive compression:
-
-To create a progressive JPEG file (or a multiple-scan sequential JPEG file),
-set the scan_info cinfo field to point to an array of scan descriptors, and
-perform compression as usual. Instead of constructing your own scan list,
-you can call the jpeg_simple_progression() helper routine to create a
-recommended progression sequence; this method should be used by all
-applications that don't want to get involved in the nitty-gritty of
-progressive scan sequence design. (If you want to provide user control of
-scan sequences, you may wish to borrow the scan script reading code found
-in rdswitch.c, so that you can read scan script files just like cjpeg's.)
-When scan_info is not NULL, the compression library will store DCT'd data
-into a buffer array as jpeg_write_scanlines() is called, and will emit all
-the requested scans during jpeg_finish_compress(). This implies that
-multiple-scan output cannot be created with a suspending data destination
-manager, since jpeg_finish_compress() does not support suspension. We
-should also note that the compressor currently forces Huffman optimization
-mode when creating a progressive JPEG file, because the default Huffman
-tables are unsuitable for progressive files.
-
-Progressive decompression:
-
-When buffered-image mode is not used, the decoder library will read all of
-a multi-scan file during jpeg_start_decompress(), so that it can provide a
-final decoded image. (Here "multi-scan" means either progressive or
-multi-scan sequential.) This makes multi-scan files transparent to the
-decoding application. However, existing applications that used suspending
-input with version 5 of the IJG library will need to be modified to check
-for a suspension return from jpeg_start_decompress().
-
-To perform incremental display, an application must use the library's
-buffered-image mode. This is described in the next section.
-
-
-Buffered-image mode
--------------------
-
-In buffered-image mode, the library stores the partially decoded image in a
-coefficient buffer, from which it can be read out as many times as desired.
-This mode is typically used for incremental display of progressive JPEG files,
-but it can be used with any JPEG file. Each scan of a progressive JPEG file
-adds more data (more detail) to the buffered image. The application can
-display in lockstep with the source file (one display pass per input scan),
-or it can allow input processing to outrun display processing. By making
-input and display processing run independently, it is possible for the
-application to adapt progressive display to a wide range of data transmission
-rates.
-
-The basic control flow for buffered-image decoding is
-
- jpeg_create_decompress()
- set data source
- jpeg_read_header()
- set overall decompression parameters
- cinfo.buffered_image = TRUE; /* select buffered-image mode */
- jpeg_start_decompress()
- for (each output pass) {
- adjust output decompression parameters if required
- jpeg_start_output() /* start a new output pass */
- for (all scanlines in image) {
- jpeg_read_scanlines()
- display scanlines
- }
- jpeg_finish_output() /* terminate output pass */
- }
- jpeg_finish_decompress()
- jpeg_destroy_decompress()
-
-This differs from ordinary unbuffered decoding in that there is an additional
-level of looping. The application can choose how many output passes to make
-and how to display each pass.
-
-The simplest approach to displaying progressive images is to do one display
-pass for each scan appearing in the input file. In this case the outer loop
-condition is typically
- while (! jpeg_input_complete(&cinfo))
-and the start-output call should read
- jpeg_start_output(&cinfo, cinfo.input_scan_number);
-The second parameter to jpeg_start_output() indicates which scan of the input
-file is to be displayed; the scans are numbered starting at 1 for this
-purpose. (You can use a loop counter starting at 1 if you like, but using
-the library's input scan counter is easier.) The library automatically reads
-data as necessary to complete each requested scan, and jpeg_finish_output()
-advances to the next scan or end-of-image marker (hence input_scan_number
-will be incremented by the time control arrives back at jpeg_start_output()).
-With this technique, data is read from the input file only as needed, and
-input and output processing run in lockstep.
-
-After reading the final scan and reaching the end of the input file, the
-buffered image remains available; it can be read additional times by
-repeating the jpeg_start_output()/jpeg_read_scanlines()/jpeg_finish_output()
-sequence. For example, a useful technique is to use fast one-pass color
-quantization for display passes made while the image is arriving, followed by
-a final display pass using two-pass quantization for highest quality. This
-is done by changing the library parameters before the final output pass.
-Changing parameters between passes is discussed in detail below.
-
-In general the last scan of a progressive file cannot be recognized as such
-until after it is read, so a post-input display pass is the best approach if
-you want special processing in the final pass.
-
-When done with the image, be sure to call jpeg_finish_decompress() to release
-the buffered image (or just use jpeg_destroy_decompress()).
-
-If input data arrives faster than it can be displayed, the application can
-cause the library to decode input data in advance of what's needed to produce
-output. This is done by calling the routine jpeg_consume_input().
-The return value is one of the following:
- JPEG_REACHED_SOS: reached an SOS marker (the start of a new scan)
- JPEG_REACHED_EOI: reached the EOI marker (end of image)
- JPEG_ROW_COMPLETED: completed reading one MCU row of compressed data
- JPEG_SCAN_COMPLETED: completed reading last MCU row of current scan
- JPEG_SUSPENDED: suspended before completing any of the above
-(JPEG_SUSPENDED can occur only if a suspending data source is used.) This
-routine can be called at any time after initializing the JPEG object. It
-reads some additional data and returns when one of the indicated significant
-events occurs. (If called after the EOI marker is reached, it will
-immediately return JPEG_REACHED_EOI without attempting to read more data.)
-
-The library's output processing will automatically call jpeg_consume_input()
-whenever the output processing overtakes the input; thus, simple lockstep
-display requires no direct calls to jpeg_consume_input(). But by adding
-calls to jpeg_consume_input(), you can absorb data in advance of what is
-being displayed. This has two benefits:
- * You can limit buildup of unprocessed data in your input buffer.
- * You can eliminate extra display passes by paying attention to the
- state of the library's input processing.
-
-The first of these benefits only requires interspersing calls to
-jpeg_consume_input() with your display operations and any other processing
-you may be doing. To avoid wasting cycles due to backtracking, it's best to
-call jpeg_consume_input() only after a hundred or so new bytes have arrived.
-This is discussed further under "I/O suspension", above. (Note: the JPEG
-library currently is not thread-safe. You must not call jpeg_consume_input()
-from one thread of control if a different library routine is working on the
-same JPEG object in another thread.)
-
-When input arrives fast enough that more than one new scan is available
-before you start a new output pass, you may as well skip the output pass
-corresponding to the completed scan. This occurs for free if you pass
-cinfo.input_scan_number as the target scan number to jpeg_start_output().
-The input_scan_number field is simply the index of the scan currently being
-consumed by the input processor. You can ensure that this is up-to-date by
-emptying the input buffer just before calling jpeg_start_output(): call
-jpeg_consume_input() repeatedly until it returns JPEG_SUSPENDED or
-JPEG_REACHED_EOI.
-
-The target scan number passed to jpeg_start_output() is saved in the
-cinfo.output_scan_number field. The library's output processing calls
-jpeg_consume_input() whenever the current input scan number and row within
-that scan is less than or equal to the current output scan number and row.
-Thus, input processing can "get ahead" of the output processing but is not
-allowed to "fall behind". You can achieve several different effects by
-manipulating this interlock rule. For example, if you pass a target scan
-number greater than the current input scan number, the output processor will
-wait until that scan starts to arrive before producing any output. (To avoid
-an infinite loop, the target scan number is automatically reset to the last
-scan number when the end of image is reached. Thus, if you specify a large
-target scan number, the library will just absorb the entire input file and
-then perform an output pass. This is effectively the same as what
-jpeg_start_decompress() does when you don't select buffered-image mode.)
-When you pass a target scan number equal to the current input scan number,
-the image is displayed no faster than the current input scan arrives. The
-final possibility is to pass a target scan number less than the current input
-scan number; this disables the input/output interlock and causes the output
-processor to simply display whatever it finds in the image buffer, without
-waiting for input. (However, the library will not accept a target scan
-number less than one, so you can't avoid waiting for the first scan.)
-
-When data is arriving faster than the output display processing can advance
-through the image, jpeg_consume_input() will store data into the buffered
-image beyond the point at which the output processing is reading data out
-again. If the input arrives fast enough, it may "wrap around" the buffer to
-the point where the input is more than one whole scan ahead of the output.
-If the output processing simply proceeds through its display pass without
-paying attention to the input, the effect seen on-screen is that the lower
-part of the image is one or more scans better in quality than the upper part.
-Then, when the next output scan is started, you have a choice of what target
-scan number to use. The recommended choice is to use the current input scan
-number at that time, which implies that you've skipped the output scans
-corresponding to the input scans that were completed while you processed the
-previous output scan. In this way, the decoder automatically adapts its
-speed to the arriving data, by skipping output scans as necessary to keep up
-with the arriving data.
-
-When using this strategy, you'll want to be sure that you perform a final
-output pass after receiving all the data; otherwise your last display may not
-be full quality across the whole screen. So the right outer loop logic is
-something like this:
- do {
- absorb any waiting input by calling jpeg_consume_input()
- final_pass = jpeg_input_complete(&cinfo);
- adjust output decompression parameters if required
- jpeg_start_output(&cinfo, cinfo.input_scan_number);
- ...
- jpeg_finish_output()
- } while (! final_pass);
-rather than quitting as soon as jpeg_input_complete() returns TRUE. This
-arrangement makes it simple to use higher-quality decoding parameters
-for the final pass. But if you don't want to use special parameters for
-the final pass, the right loop logic is like this:
- for (;;) {
- absorb any waiting input by calling jpeg_consume_input()
- jpeg_start_output(&cinfo, cinfo.input_scan_number);
- ...
- jpeg_finish_output()
- if (jpeg_input_complete(&cinfo) &&
- cinfo.input_scan_number == cinfo.output_scan_number)
- break;
- }
-In this case you don't need to know in advance whether an output pass is to
-be the last one, so it's not necessary to have reached EOF before starting
-the final output pass; rather, what you want to test is whether the output
-pass was performed in sync with the final input scan. This form of the loop
-will avoid an extra output pass whenever the decoder is able (or nearly able)
-to keep up with the incoming data.
-
-When the data transmission speed is high, you might begin a display pass,
-then find that much or all of the file has arrived before you can complete
-the pass. (You can detect this by noting the JPEG_REACHED_EOI return code
-from jpeg_consume_input(), or equivalently by testing jpeg_input_complete().)
-In this situation you may wish to abort the current display pass and start a
-new one using the newly arrived information. To do so, just call
-jpeg_finish_output() and then start a new pass with jpeg_start_output().
-
-A variant strategy is to abort and restart display if more than one complete
-scan arrives during an output pass; this can be detected by noting
-JPEG_REACHED_SOS returns and/or examining cinfo.input_scan_number. This
-idea should be employed with caution, however, since the display process
-might never get to the bottom of the image before being aborted, resulting
-in the lower part of the screen being several passes worse than the upper.
-In most cases it's probably best to abort an output pass only if the whole
-file has arrived and you want to begin the final output pass immediately.
-
-When receiving data across a communication link, we recommend always using
-the current input scan number for the output target scan number; if a
-higher-quality final pass is to be done, it should be started (aborting any
-incomplete output pass) as soon as the end of file is received. However,
-many other strategies are possible. For example, the application can examine
-the parameters of the current input scan and decide whether to display it or
-not. If the scan contains only chroma data, one might choose not to use it
-as the target scan, expecting that the scan will be small and will arrive
-quickly. To skip to the next scan, call jpeg_consume_input() until it
-returns JPEG_REACHED_SOS or JPEG_REACHED_EOI. Or just use the next higher
-number as the target scan for jpeg_start_output(); but that method doesn't
-let you inspect the next scan's parameters before deciding to display it.
-
-
-In buffered-image mode, jpeg_start_decompress() never performs input and
-thus never suspends. An application that uses input suspension with
-buffered-image mode must be prepared for suspension returns from these
-routines:
-* jpeg_start_output() performs input only if you request 2-pass quantization
- and the target scan isn't fully read yet. (This is discussed below.)
-* jpeg_read_scanlines(), as always, returns the number of scanlines that it
- was able to produce before suspending.
-* jpeg_finish_output() will read any markers following the target scan,
- up to the end of the file or the SOS marker that begins another scan.
- (But it reads no input if jpeg_consume_input() has already reached the
- end of the file or a SOS marker beyond the target output scan.)
-* jpeg_finish_decompress() will read until the end of file, and thus can
- suspend if the end hasn't already been reached (as can be tested by
- calling jpeg_input_complete()).
-jpeg_start_output(), jpeg_finish_output(), and jpeg_finish_decompress()
-all return TRUE if they completed their tasks, FALSE if they had to suspend.
-In the event of a FALSE return, the application must load more input data
-and repeat the call. Applications that use non-suspending data sources need
-not check the return values of these three routines.
-
-
-It is possible to change decoding parameters between output passes in the
-buffered-image mode. The decoder library currently supports only very
-limited changes of parameters. ONLY THE FOLLOWING parameter changes are
-allowed after jpeg_start_decompress() is called:
-* dct_method can be changed before each call to jpeg_start_output().
- For example, one could use a fast DCT method for early scans, changing
- to a higher quality method for the final scan.
-* dither_mode can be changed before each call to jpeg_start_output();
- of course this has no impact if not using color quantization. Typically
- one would use ordered dither for initial passes, then switch to
- Floyd-Steinberg dither for the final pass. Caution: changing dither mode
- can cause more memory to be allocated by the library. Although the amount
- of memory involved is not large (a scanline or so), it may cause the
- initial max_memory_to_use specification to be exceeded, which in the worst
- case would result in an out-of-memory failure.
-* do_block_smoothing can be changed before each call to jpeg_start_output().
- This setting is relevant only when decoding a progressive JPEG image.
- During the first DC-only scan, block smoothing provides a very "fuzzy" look
- instead of the very "blocky" look seen without it; which is better seems a
- matter of personal taste. But block smoothing is nearly always a win
- during later stages, especially when decoding a successive-approximation
- image: smoothing helps to hide the slight blockiness that otherwise shows
- up on smooth gradients until the lowest coefficient bits are sent.
-* Color quantization mode can be changed under the rules described below.
- You *cannot* change between full-color and quantized output (because that
- would alter the required I/O buffer sizes), but you can change which
- quantization method is used.
-
-When generating color-quantized output, changing quantization method is a
-very useful way of switching between high-speed and high-quality display.
-The library allows you to change among its three quantization methods:
-1. Single-pass quantization to a fixed color cube.
- Selected by cinfo.two_pass_quantize = FALSE and cinfo.colormap = NULL.
-2. Single-pass quantization to an application-supplied colormap.
- Selected by setting cinfo.colormap to point to the colormap (the value of
- two_pass_quantize is ignored); also set cinfo.actual_number_of_colors.
-3. Two-pass quantization to a colormap chosen specifically for the image.
- Selected by cinfo.two_pass_quantize = TRUE and cinfo.colormap = NULL.
- (This is the default setting selected by jpeg_read_header, but it is
- probably NOT what you want for the first pass of progressive display!)
-These methods offer successively better quality and lesser speed. However,
-only the first method is available for quantizing in non-RGB color spaces.
-
-IMPORTANT: because the different quantizer methods have very different
-working-storage requirements, the library requires you to indicate which
-one(s) you intend to use before you call jpeg_start_decompress(). (If we did
-not require this, the max_memory_to_use setting would be a complete fiction.)
-You do this by setting one or more of these three cinfo fields to TRUE:
- enable_1pass_quant Fixed color cube colormap
- enable_external_quant Externally-supplied colormap
- enable_2pass_quant Two-pass custom colormap
-All three are initialized FALSE by jpeg_read_header(). But
-jpeg_start_decompress() automatically sets TRUE the one selected by the
-current two_pass_quantize and colormap settings, so you only need to set the
-enable flags for any other quantization methods you plan to change to later.
-
-After setting the enable flags correctly at jpeg_start_decompress() time, you
-can change to any enabled quantization method by setting two_pass_quantize
-and colormap properly just before calling jpeg_start_output(). The following
-special rules apply:
-1. You must explicitly set cinfo.colormap to NULL when switching to 1-pass
- or 2-pass mode from a different mode, or when you want the 2-pass
- quantizer to be re-run to generate a new colormap.
-2. To switch to an external colormap, or to change to a different external
- colormap than was used on the prior pass, you must call
- jpeg_new_colormap() after setting cinfo.colormap.
-NOTE: if you want to use the same colormap as was used in the prior pass,
-you should not do either of these things. This will save some nontrivial
-switchover costs.
-(These requirements exist because cinfo.colormap will always be non-NULL
-after completing a prior output pass, since both the 1-pass and 2-pass
-quantizers set it to point to their output colormaps. Thus you have to
-do one of these two things to notify the library that something has changed.
-Yup, it's a bit klugy, but it's necessary to do it this way for backwards
-compatibility.)
-
-Note that in buffered-image mode, the library generates any requested colormap
-during jpeg_start_output(), not during jpeg_start_decompress().
-
-When using two-pass quantization, jpeg_start_output() makes a pass over the
-buffered image to determine the optimum color map; it therefore may take a
-significant amount of time, whereas ordinarily it does little work. The
-progress monitor hook is called during this pass, if defined. It is also
-important to realize that if the specified target scan number is greater than
-or equal to the current input scan number, jpeg_start_output() will attempt
-to consume input as it makes this pass. If you use a suspending data source,
-you need to check for a FALSE return from jpeg_start_output() under these
-conditions. The combination of 2-pass quantization and a not-yet-fully-read
-target scan is the only case in which jpeg_start_output() will consume input.
-
-
-Application authors who support buffered-image mode may be tempted to use it
-for all JPEG images, even single-scan ones. This will work, but it is
-inefficient: there is no need to create an image-sized coefficient buffer for
-single-scan images. Requesting buffered-image mode for such an image wastes
-memory. Worse, it can cost time on large images, since the buffered data has
-to be swapped out or written to a temporary file. If you are concerned about
-maximum performance on baseline JPEG files, you should use buffered-image
-mode only when the incoming file actually has multiple scans. This can be
-tested by calling jpeg_has_multiple_scans(), which will return a correct
-result at any time after jpeg_read_header() completes.
-
-It is also worth noting that when you use jpeg_consume_input() to let input
-processing get ahead of output processing, the resulting pattern of access to
-the coefficient buffer is quite nonsequential. It's best to use the memory
-manager jmemnobs.c if you can (ie, if you have enough real or virtual main
-memory). If not, at least make sure that max_memory_to_use is set as high as
-possible. If the JPEG memory manager has to use a temporary file, you will
-probably see a lot of disk traffic and poor performance. (This could be
-improved with additional work on the memory manager, but we haven't gotten
-around to it yet.)
-
-In some applications it may be convenient to use jpeg_consume_input() for all
-input processing, including reading the initial markers; that is, you may
-wish to call jpeg_consume_input() instead of jpeg_read_header() during
-startup. This works, but note that you must check for JPEG_REACHED_SOS and
-JPEG_REACHED_EOI return codes as the equivalent of jpeg_read_header's codes.
-Once the first SOS marker has been reached, you must call
-jpeg_start_decompress() before jpeg_consume_input() will consume more input;
-it'll just keep returning JPEG_REACHED_SOS until you do. If you read a
-tables-only file this way, jpeg_consume_input() will return JPEG_REACHED_EOI
-without ever returning JPEG_REACHED_SOS; be sure to check for this case.
-If this happens, the decompressor will not read any more input until you call
-jpeg_abort() to reset it. It is OK to call jpeg_consume_input() even when not
-using buffered-image mode, but in that case it's basically a no-op after the
-initial markers have been read: it will just return JPEG_SUSPENDED.
-
-
-Abbreviated datastreams and multiple images
--------------------------------------------
-
-A JPEG compression or decompression object can be reused to process multiple
-images. This saves a small amount of time per image by eliminating the
-"create" and "destroy" operations, but that isn't the real purpose of the
-feature. Rather, reuse of an object provides support for abbreviated JPEG
-datastreams. Object reuse can also simplify processing a series of images in
-a single input or output file. This section explains these features.
-
-A JPEG file normally contains several hundred bytes worth of quantization
-and Huffman tables. In a situation where many images will be stored or
-transmitted with identical tables, this may represent an annoying overhead.
-The JPEG standard therefore permits tables to be omitted. The standard
-defines three classes of JPEG datastreams:
- * "Interchange" datastreams contain an image and all tables needed to decode
- the image. These are the usual kind of JPEG file.
- * "Abbreviated image" datastreams contain an image, but are missing some or
- all of the tables needed to decode that image.
- * "Abbreviated table specification" (henceforth "tables-only") datastreams
- contain only table specifications.
-To decode an abbreviated image, it is necessary to load the missing table(s)
-into the decoder beforehand. This can be accomplished by reading a separate
-tables-only file. A variant scheme uses a series of images in which the first
-image is an interchange (complete) datastream, while subsequent ones are
-abbreviated and rely on the tables loaded by the first image. It is assumed
-that once the decoder has read a table, it will remember that table until a
-new definition for the same table number is encountered.
-
-It is the application designer's responsibility to figure out how to associate
-the correct tables with an abbreviated image. While abbreviated datastreams
-can be useful in a closed environment, their use is strongly discouraged in
-any situation where data exchange with other applications might be needed.
-Caveat designer.
-
-The JPEG library provides support for reading and writing any combination of
-tables-only datastreams and abbreviated images. In both compression and
-decompression objects, a quantization or Huffman table will be retained for
-the lifetime of the object, unless it is overwritten by a new table definition.
-
-
-To create abbreviated image datastreams, it is only necessary to tell the
-compressor not to emit some or all of the tables it is using. Each
-quantization and Huffman table struct contains a boolean field "sent_table",
-which normally is initialized to FALSE. For each table used by the image, the
-header-writing process emits the table and sets sent_table = TRUE unless it is
-already TRUE. (In normal usage, this prevents outputting the same table
-definition multiple times, as would otherwise occur because the chroma
-components typically share tables.) Thus, setting this field to TRUE before
-calling jpeg_start_compress() will prevent the table from being written at
-all.
-
-If you want to create a "pure" abbreviated image file containing no tables,
-just call "jpeg_suppress_tables(&cinfo, TRUE)" after constructing all the
-tables. If you want to emit some but not all tables, you'll need to set the
-individual sent_table fields directly.
-
-To create an abbreviated image, you must also call jpeg_start_compress()
-with a second parameter of FALSE, not TRUE. Otherwise jpeg_start_compress()
-will force all the sent_table fields to FALSE. (This is a safety feature to
-prevent abbreviated images from being created accidentally.)
-
-To create a tables-only file, perform the same parameter setup that you
-normally would, but instead of calling jpeg_start_compress() and so on, call
-jpeg_write_tables(&cinfo). This will write an abbreviated datastream
-containing only SOI, DQT and/or DHT markers, and EOI. All the quantization
-and Huffman tables that are currently defined in the compression object will
-be emitted unless their sent_tables flag is already TRUE, and then all the
-sent_tables flags will be set TRUE.
-
-A sure-fire way to create matching tables-only and abbreviated image files
-is to proceed as follows:
-
- create JPEG compression object
- set JPEG parameters
- set destination to tables-only file
- jpeg_write_tables(&cinfo);
- set destination to image file
- jpeg_start_compress(&cinfo, FALSE);
- write data...
- jpeg_finish_compress(&cinfo);
-
-Since the JPEG parameters are not altered between writing the table file and
-the abbreviated image file, the same tables are sure to be used. Of course,
-you can repeat the jpeg_start_compress() ... jpeg_finish_compress() sequence
-many times to produce many abbreviated image files matching the table file.
-
-You cannot suppress output of the computed Huffman tables when Huffman
-optimization is selected. (If you could, there'd be no way to decode the
-image...) Generally, you don't want to set optimize_coding = TRUE when
-you are trying to produce abbreviated files.
-
-In some cases you might want to compress an image using tables which are
-not stored in the application, but are defined in an interchange or
-tables-only file readable by the application. This can be done by setting up
-a JPEG decompression object to read the specification file, then copying the
-tables into your compression object. See jpeg_copy_critical_parameters()
-for an example of copying quantization tables.
-
-
-To read abbreviated image files, you simply need to load the proper tables
-into the decompression object before trying to read the abbreviated image.
-If the proper tables are stored in the application program, you can just
-allocate the table structs and fill in their contents directly. For example,
-to load a fixed quantization table into table slot "n":
-
- if (cinfo.quant_tbl_ptrs[n] == NULL)
- cinfo.quant_tbl_ptrs[n] = jpeg_alloc_quant_table((j_common_ptr) &cinfo);
- quant_ptr = cinfo.quant_tbl_ptrs[n]; /* quant_ptr is JQUANT_TBL* */
- for (i = 0; i < 64; i++) {
- /* Qtable[] is desired quantization table, in natural array order */
- quant_ptr->quantval[i] = Qtable[i];
- }
-
-Code to load a fixed Huffman table is typically (for AC table "n"):
-
- if (cinfo.ac_huff_tbl_ptrs[n] == NULL)
- cinfo.ac_huff_tbl_ptrs[n] = jpeg_alloc_huff_table((j_common_ptr) &cinfo);
- huff_ptr = cinfo.ac_huff_tbl_ptrs[n]; /* huff_ptr is JHUFF_TBL* */
- for (i = 1; i <= 16; i++) {
- /* counts[i] is number of Huffman codes of length i bits, i=1..16 */
- huff_ptr->bits[i] = counts[i];
- }
- for (i = 0; i < 256; i++) {
- /* symbols[] is the list of Huffman symbols, in code-length order */
- huff_ptr->huffval[i] = symbols[i];
- }
-
-(Note that trying to set cinfo.quant_tbl_ptrs[n] to point directly at a
-constant JQUANT_TBL object is not safe. If the incoming file happened to
-contain a quantization table definition, your master table would get
-overwritten! Instead allocate a working table copy and copy the master table
-into it, as illustrated above. Ditto for Huffman tables, of course.)
-
-You might want to read the tables from a tables-only file, rather than
-hard-wiring them into your application. The jpeg_read_header() call is
-sufficient to read a tables-only file. You must pass a second parameter of
-FALSE to indicate that you do not require an image to be present. Thus, the
-typical scenario is
-
- create JPEG decompression object
- set source to tables-only file
- jpeg_read_header(&cinfo, FALSE);
- set source to abbreviated image file
- jpeg_read_header(&cinfo, TRUE);
- set decompression parameters
- jpeg_start_decompress(&cinfo);
- read data...
- jpeg_finish_decompress(&cinfo);
-
-In some cases, you may want to read a file without knowing whether it contains
-an image or just tables. In that case, pass FALSE and check the return value
-from jpeg_read_header(): it will be JPEG_HEADER_OK if an image was found,
-JPEG_HEADER_TABLES_ONLY if only tables were found. (A third return value,
-JPEG_SUSPENDED, is possible when using a suspending data source manager.)
-Note that jpeg_read_header() will not complain if you read an abbreviated
-image for which you haven't loaded the missing tables; the missing-table check
-occurs later, in jpeg_start_decompress().
-
-
-It is possible to read a series of images from a single source file by
-repeating the jpeg_read_header() ... jpeg_finish_decompress() sequence,
-without releasing/recreating the JPEG object or the data source module.
-(If you did reinitialize, any partial bufferload left in the data source
-buffer at the end of one image would be discarded, causing you to lose the
-start of the next image.) When you use this method, stored tables are
-automatically carried forward, so some of the images can be abbreviated images
-that depend on tables from earlier images.
-
-If you intend to write a series of images into a single destination file,
-you might want to make a specialized data destination module that doesn't
-flush the output buffer at term_destination() time. This would speed things
-up by some trifling amount. Of course, you'd need to remember to flush the
-buffer after the last image. You can make the later images be abbreviated
-ones by passing FALSE to jpeg_start_compress().
-
-
-Special markers
----------------
-
-Some applications may need to insert or extract special data in the JPEG
-datastream. The JPEG standard provides marker types "COM" (comment) and
-"APP0" through "APP15" (application) to hold application-specific data.
-Unfortunately, the use of these markers is not specified by the standard.
-COM markers are fairly widely used to hold user-supplied text. The JFIF file
-format spec uses APP0 markers with specified initial strings to hold certain
-data. Adobe applications use APP14 markers beginning with the string "Adobe"
-for miscellaneous data. Other APPn markers are rarely seen, but might
-contain almost anything.
-
-If you wish to store user-supplied text, we recommend you use COM markers
-and place readable 7-bit ASCII text in them. Newline conventions are not
-standardized --- expect to find LF (Unix style), CR/LF (DOS style), or CR
-(Mac style). A robust COM reader should be able to cope with random binary
-garbage, including nulls, since some applications generate COM markers
-containing non-ASCII junk. (But yours should not be one of them.)
-
-For program-supplied data, use an APPn marker, and be sure to begin it with an
-identifying string so that you can tell whether the marker is actually yours.
-It's probably best to avoid using APP0 or APP14 for any private markers.
-(NOTE: the upcoming SPIFF standard will use APP8 markers; we recommend you
-not use APP8 markers for any private purposes, either.)
-
-Keep in mind that at most 65533 bytes can be put into one marker, but you
-can have as many markers as you like.
-
-By default, the IJG compression library will write a JFIF APP0 marker if the
-selected JPEG colorspace is grayscale or YCbCr, or an Adobe APP14 marker if
-the selected colorspace is RGB, CMYK, or YCCK. You can disable this, but
-we don't recommend it. The decompression library will recognize JFIF and
-Adobe markers and will set the JPEG colorspace properly when one is found.
-
-
-You can write special markers immediately following the datastream header by
-calling jpeg_write_marker() after jpeg_start_compress() and before the first
-call to jpeg_write_scanlines(). When you do this, the markers appear after
-the SOI and the JFIF APP0 and Adobe APP14 markers (if written), but before
-all else. Specify the marker type parameter as "JPEG_COM" for COM or
-"JPEG_APP0 + n" for APPn. (Actually, jpeg_write_marker will let you write
-any marker type, but we don't recommend writing any other kinds of marker.)
-For example, to write a user comment string pointed to by comment_text:
- jpeg_write_marker(cinfo, JPEG_COM, comment_text, strlen(comment_text));
-
-If it's not convenient to store all the marker data in memory at once,
-you can instead call jpeg_write_m_header() followed by multiple calls to
-jpeg_write_m_byte(). If you do it this way, it's your responsibility to
-call jpeg_write_m_byte() exactly the number of times given in the length
-parameter to jpeg_write_m_header(). (This method lets you empty the
-output buffer partway through a marker, which might be important when
-using a suspending data destination module. In any case, if you are using
-a suspending destination, you should flush its buffer after inserting
-any special markers. See "I/O suspension".)
-
-Or, if you prefer to synthesize the marker byte sequence yourself,
-you can just cram it straight into the data destination module.
-
-If you are writing JFIF 1.02 extension markers (thumbnail images), don't
-forget to set cinfo.JFIF_minor_version = 2 so that the encoder will write the
-correct JFIF version number in the JFIF header marker. The library's default
-is to write version 1.01, but that's wrong if you insert any 1.02 extension
-markers. (We could probably get away with just defaulting to 1.02, but there
-used to be broken decoders that would complain about unknown minor version
-numbers. To reduce compatibility risks it's safest not to write 1.02 unless
-you are actually using 1.02 extensions.)
-
-
-When reading, two methods of handling special markers are available:
-1. You can ask the library to save the contents of COM and/or APPn markers
-into memory, and then examine them at your leisure afterwards.
-2. You can supply your own routine to process COM and/or APPn markers
-on-the-fly as they are read.
-The first method is simpler to use, especially if you are using a suspending
-data source; writing a marker processor that copes with input suspension is
-not easy (consider what happens if the marker is longer than your available
-input buffer). However, the second method conserves memory since the marker
-data need not be kept around after it's been processed.
-
-For either method, you'd normally set up marker handling after creating a
-decompression object and before calling jpeg_read_header(), because the
-markers of interest will typically be near the head of the file and so will
-be scanned by jpeg_read_header. Once you've established a marker handling
-method, it will be used for the life of that decompression object
-(potentially many datastreams), unless you change it. Marker handling is
-determined separately for COM markers and for each APPn marker code.
-
-
-To save the contents of special markers in memory, call
- jpeg_save_markers(cinfo, marker_code, length_limit)
-where marker_code is the marker type to save, JPEG_COM or JPEG_APP0+n.
-(To arrange to save all the special marker types, you need to call this
-routine 17 times, for COM and APP0-APP15.) If the incoming marker is longer
-than length_limit data bytes, only length_limit bytes will be saved; this
-parameter allows you to avoid chewing up memory when you only need to see the
-first few bytes of a potentially large marker. If you want to save all the
-data, set length_limit to 0xFFFF; that is enough since marker lengths are only
-16 bits. As a special case, setting length_limit to 0 prevents that marker
-type from being saved at all. (That is the default behavior, in fact.)
-
-After jpeg_read_header() completes, you can examine the special markers by
-following the cinfo->marker_list pointer chain. All the special markers in
-the file appear in this list, in order of their occurrence in the file (but
-omitting any markers of types you didn't ask for). Both the original data
-length and the saved data length are recorded for each list entry; the latter
-will not exceed length_limit for the particular marker type. Note that these
-lengths exclude the marker length word, whereas the stored representation
-within the JPEG file includes it. (Hence the maximum data length is really
-only 65533.)
-
-It is possible that additional special markers appear in the file beyond the
-SOS marker at which jpeg_read_header stops; if so, the marker list will be
-extended during reading of the rest of the file. This is not expected to be
-common, however. If you are short on memory you may want to reset the length
-limit to zero for all marker types after finishing jpeg_read_header, to
-ensure that the max_memory_to_use setting cannot be exceeded due to addition
-of later markers.
-
-The marker list remains stored until you call jpeg_finish_decompress or
-jpeg_abort, at which point the memory is freed and the list is set to empty.
-(jpeg_destroy also releases the storage, of course.)
-
-Note that the library is internally interested in APP0 and APP14 markers;
-if you try to set a small nonzero length limit on these types, the library
-will silently force the length up to the minimum it wants. (But you can set
-a zero length limit to prevent them from being saved at all.) Also, in a
-16-bit environment, the maximum length limit may be constrained to less than
-65533 by malloc() limitations. It is therefore best not to assume that the
-effective length limit is exactly what you set it to be.
-
-
-If you want to supply your own marker-reading routine, you do it by calling
-jpeg_set_marker_processor(). A marker processor routine must have the
-signature
- boolean jpeg_marker_parser_method (j_decompress_ptr cinfo)
-Although the marker code is not explicitly passed, the routine can find it
-in cinfo->unread_marker. At the time of call, the marker proper has been
-read from the data source module. The processor routine is responsible for
-reading the marker length word and the remaining parameter bytes, if any.
-Return TRUE to indicate success. (FALSE should be returned only if you are
-using a suspending data source and it tells you to suspend. See the standard
-marker processors in jdmarker.c for appropriate coding methods if you need to
-use a suspending data source.)
-
-If you override the default APP0 or APP14 processors, it is up to you to
-recognize JFIF and Adobe markers if you want colorspace recognition to occur
-properly. We recommend copying and extending the default processors if you
-want to do that. (A better idea is to save these marker types for later
-examination by calling jpeg_save_markers(); that method doesn't interfere
-with the library's own processing of these markers.)
-
-jpeg_set_marker_processor() and jpeg_save_markers() are mutually exclusive
---- if you call one it overrides any previous call to the other, for the
-particular marker type specified.
-
-A simple example of an external COM processor can be found in djpeg.c.
-Also, see jpegtran.c for an example of using jpeg_save_markers.
-
-
-Raw (downsampled) image data
-----------------------------
-
-Some applications need to supply already-downsampled image data to the JPEG
-compressor, or to receive raw downsampled data from the decompressor. The
-library supports this requirement by allowing the application to write or
-read raw data, bypassing the normal preprocessing or postprocessing steps.
-The interface is different from the standard one and is somewhat harder to
-use. If your interest is merely in bypassing color conversion, we recommend
-that you use the standard interface and simply set jpeg_color_space =
-in_color_space (or jpeg_color_space = out_color_space for decompression).
-The mechanism described in this section is necessary only to supply or
-receive downsampled image data, in which not all components have the same
-dimensions.
-
-
-To compress raw data, you must supply the data in the colorspace to be used
-in the JPEG file (please read the earlier section on Special color spaces)
-and downsampled to the sampling factors specified in the JPEG parameters.
-You must supply the data in the format used internally by the JPEG library,
-namely a JSAMPIMAGE array. This is an array of pointers to two-dimensional
-arrays, each of type JSAMPARRAY. Each 2-D array holds the values for one
-color component. This structure is necessary since the components are of
-different sizes. If the image dimensions are not a multiple of the MCU size,
-you must also pad the data correctly (usually, this is done by replicating
-the last column and/or row). The data must be padded to a multiple of a DCT
-block in each component: that is, each downsampled row must contain a
-multiple of block_size valid samples, and there must be a multiple of
-block_size sample rows for each component. (For applications such as
-conversion of digital TV images, the standard image size is usually a
-multiple of the DCT block size, so that no padding need actually be done.)
-
-The procedure for compression of raw data is basically the same as normal
-compression, except that you call jpeg_write_raw_data() in place of
-jpeg_write_scanlines(). Before calling jpeg_start_compress(), you must do
-the following:
- * Set cinfo->raw_data_in to TRUE. (It is set FALSE by jpeg_set_defaults().)
- This notifies the library that you will be supplying raw data.
- Furthermore, set cinfo->do_fancy_downsampling to FALSE if you want to use
- real downsampled data. (It is set TRUE by jpeg_set_defaults().)
- * Ensure jpeg_color_space is correct --- an explicit jpeg_set_colorspace()
- call is a good idea. Note that since color conversion is bypassed,
- in_color_space is ignored, except that jpeg_set_defaults() uses it to
- choose the default jpeg_color_space setting.
- * Ensure the sampling factors, cinfo->comp_info[i].h_samp_factor and
- cinfo->comp_info[i].v_samp_factor, are correct. Since these indicate the
- dimensions of the data you are supplying, it's wise to set them
- explicitly, rather than assuming the library's defaults are what you want.
-
-To pass raw data to the library, call jpeg_write_raw_data() in place of
-jpeg_write_scanlines(). The two routines work similarly except that
-jpeg_write_raw_data takes a JSAMPIMAGE data array rather than JSAMPARRAY.
-The scanlines count passed to and returned from jpeg_write_raw_data is
-measured in terms of the component with the largest v_samp_factor.
-
-jpeg_write_raw_data() processes one MCU row per call, which is to say
-v_samp_factor*block_size sample rows of each component. The passed num_lines
-value must be at least max_v_samp_factor*block_size, and the return value
-will be exactly that amount (or possibly some multiple of that amount, in
-future library versions). This is true even on the last call at the bottom
-of the image; don't forget to pad your data as necessary.
-
-The required dimensions of the supplied data can be computed for each
-component as
- cinfo->comp_info[i].width_in_blocks*block_size samples per row
- cinfo->comp_info[i].height_in_blocks*block_size rows in image
-after jpeg_start_compress() has initialized those fields. If the valid data
-is smaller than this, it must be padded appropriately. For some sampling
-factors and image sizes, additional dummy DCT blocks are inserted to make
-the image a multiple of the MCU dimensions. The library creates such dummy
-blocks itself; it does not read them from your supplied data. Therefore you
-need never pad by more than block_size samples. An example may help here.
-Assume 2h2v downsampling of YCbCr data, that is
- cinfo->comp_info[0].h_samp_factor = 2 for Y
- cinfo->comp_info[0].v_samp_factor = 2
- cinfo->comp_info[1].h_samp_factor = 1 for Cb
- cinfo->comp_info[1].v_samp_factor = 1
- cinfo->comp_info[2].h_samp_factor = 1 for Cr
- cinfo->comp_info[2].v_samp_factor = 1
-and suppose that the nominal image dimensions (cinfo->image_width and
-cinfo->image_height) are 101x101 pixels. Then jpeg_start_compress() will
-compute downsampled_width = 101 and width_in_blocks = 13 for Y,
-downsampled_width = 51 and width_in_blocks = 7 for Cb and Cr (and the same
-for the height fields). You must pad the Y data to at least 13*8 = 104
-columns and rows, the Cb/Cr data to at least 7*8 = 56 columns and rows. The
-MCU height is max_v_samp_factor = 2 DCT rows so you must pass at least 16
-scanlines on each call to jpeg_write_raw_data(), which is to say 16 actual
-sample rows of Y and 8 each of Cb and Cr. A total of 7 MCU rows are needed,
-so you must pass a total of 7*16 = 112 "scanlines". The last DCT block row
-of Y data is dummy, so it doesn't matter what you pass for it in the data
-arrays, but the scanlines count must total up to 112 so that all of the Cb
-and Cr data gets passed.
-
-Output suspension is supported with raw-data compression: if the data
-destination module suspends, jpeg_write_raw_data() will return 0.
-In this case the same data rows must be passed again on the next call.
-
-
-Decompression with raw data output implies bypassing all postprocessing.
-You must deal with the color space and sampling factors present in the
-incoming file. If your application only handles, say, 2h1v YCbCr data,
-you must check for and fail on other color spaces or other sampling factors.
-The library will not convert to a different color space for you.
-
-To obtain raw data output, set cinfo->raw_data_out = TRUE before
-jpeg_start_decompress() (it is set FALSE by jpeg_read_header()). Be sure to
-verify that the color space and sampling factors are ones you can handle.
-Furthermore, set cinfo->do_fancy_upsampling = FALSE if you want to get real
-downsampled data (it is set TRUE by jpeg_read_header()).
-Then call jpeg_read_raw_data() in place of jpeg_read_scanlines(). The
-decompression process is otherwise the same as usual.
-
-jpeg_read_raw_data() returns one MCU row per call, and thus you must pass a
-buffer of at least max_v_samp_factor*block_size scanlines (scanline counting
-is the same as for raw-data compression). The buffer you pass must be large
-enough to hold the actual data plus padding to DCT-block boundaries. As with
-compression, any entirely dummy DCT blocks are not processed so you need not
-allocate space for them, but the total scanline count includes them. The
-above example of computing buffer dimensions for raw-data compression is
-equally valid for decompression.
-
-Input suspension is supported with raw-data decompression: if the data source
-module suspends, jpeg_read_raw_data() will return 0. You can also use
-buffered-image mode to read raw data in multiple passes.
-
-
-Really raw data: DCT coefficients
----------------------------------
-
-It is possible to read or write the contents of a JPEG file as raw DCT
-coefficients. This facility is mainly intended for use in lossless
-transcoding between different JPEG file formats. Other possible applications
-include lossless cropping of a JPEG image, lossless reassembly of a
-multi-strip or multi-tile TIFF/JPEG file into a single JPEG datastream, etc.
-
-To read the contents of a JPEG file as DCT coefficients, open the file and do
-jpeg_read_header() as usual. But instead of calling jpeg_start_decompress()
-and jpeg_read_scanlines(), call jpeg_read_coefficients(). This will read the
-entire image into a set of virtual coefficient-block arrays, one array per
-component. The return value is a pointer to an array of virtual-array
-descriptors. Each virtual array can be accessed directly using the JPEG
-memory manager's access_virt_barray method (see Memory management, below,
-and also read structure.txt's discussion of virtual array handling). Or,
-for simple transcoding to a different JPEG file format, the array list can
-just be handed directly to jpeg_write_coefficients().
-
-Each block in the block arrays contains quantized coefficient values in
-normal array order (not JPEG zigzag order). The block arrays contain only
-DCT blocks containing real data; any entirely-dummy blocks added to fill out
-interleaved MCUs at the right or bottom edges of the image are discarded
-during reading and are not stored in the block arrays. (The size of each
-block array can be determined from the width_in_blocks and height_in_blocks
-fields of the component's comp_info entry.) This is also the data format
-expected by jpeg_write_coefficients().
-
-When you are done using the virtual arrays, call jpeg_finish_decompress()
-to release the array storage and return the decompression object to an idle
-state; or just call jpeg_destroy() if you don't need to reuse the object.
-
-If you use a suspending data source, jpeg_read_coefficients() will return
-NULL if it is forced to suspend; a non-NULL return value indicates successful
-completion. You need not test for a NULL return value when using a
-non-suspending data source.
-
-It is also possible to call jpeg_read_coefficients() to obtain access to the
-decoder's coefficient arrays during a normal decode cycle in buffered-image
-mode. This frammish might be useful for progressively displaying an incoming
-image and then re-encoding it without loss. To do this, decode in buffered-
-image mode as discussed previously, then call jpeg_read_coefficients() after
-the last jpeg_finish_output() call. The arrays will be available for your use
-until you call jpeg_finish_decompress().
-
-
-To write the contents of a JPEG file as DCT coefficients, you must provide
-the DCT coefficients stored in virtual block arrays. You can either pass
-block arrays read from an input JPEG file by jpeg_read_coefficients(), or
-allocate virtual arrays from the JPEG compression object and fill them
-yourself. In either case, jpeg_write_coefficients() is substituted for
-jpeg_start_compress() and jpeg_write_scanlines(). Thus the sequence is
- * Create compression object
- * Set all compression parameters as necessary
- * Request virtual arrays if needed
- * jpeg_write_coefficients()
- * jpeg_finish_compress()
- * Destroy or re-use compression object
-jpeg_write_coefficients() is passed a pointer to an array of virtual block
-array descriptors; the number of arrays is equal to cinfo.num_components.
-
-The virtual arrays need only have been requested, not realized, before
-jpeg_write_coefficients() is called. A side-effect of
-jpeg_write_coefficients() is to realize any virtual arrays that have been
-requested from the compression object's memory manager. Thus, when obtaining
-the virtual arrays from the compression object, you should fill the arrays
-after calling jpeg_write_coefficients(). The data is actually written out
-when you call jpeg_finish_compress(); jpeg_write_coefficients() only writes
-the file header.
-
-When writing raw DCT coefficients, it is crucial that the JPEG quantization
-tables and sampling factors match the way the data was encoded, or the
-resulting file will be invalid. For transcoding from an existing JPEG file,
-we recommend using jpeg_copy_critical_parameters(). This routine initializes
-all the compression parameters to default values (like jpeg_set_defaults()),
-then copies the critical information from a source decompression object.
-The decompression object should have just been used to read the entire
-JPEG input file --- that is, it should be awaiting jpeg_finish_decompress().
-
-jpeg_write_coefficients() marks all tables stored in the compression object
-as needing to be written to the output file (thus, it acts like
-jpeg_start_compress(cinfo, TRUE)). This is for safety's sake, to avoid
-emitting abbreviated JPEG files by accident. If you really want to emit an
-abbreviated JPEG file, call jpeg_suppress_tables(), or set the tables'
-individual sent_table flags, between calling jpeg_write_coefficients() and
-jpeg_finish_compress().
-
-
-Progress monitoring
--------------------
-
-Some applications may need to regain control from the JPEG library every so
-often. The typical use of this feature is to produce a percent-done bar or
-other progress display. (For a simple example, see cjpeg.c or djpeg.c.)
-Although you do get control back frequently during the data-transferring pass
-(the jpeg_read_scanlines or jpeg_write_scanlines loop), any additional passes
-will occur inside jpeg_finish_compress or jpeg_start_decompress; those
-routines may take a long time to execute, and you don't get control back
-until they are done.
-
-You can define a progress-monitor routine which will be called periodically
-by the library. No guarantees are made about how often this call will occur,
-so we don't recommend you use it for mouse tracking or anything like that.
-At present, a call will occur once per MCU row, scanline, or sample row
-group, whichever unit is convenient for the current processing mode; so the
-wider the image, the longer the time between calls. During the data
-transferring pass, only one call occurs per call of jpeg_read_scanlines or
-jpeg_write_scanlines, so don't pass a large number of scanlines at once if
-you want fine resolution in the progress count. (If you really need to use
-the callback mechanism for time-critical tasks like mouse tracking, you could
-insert additional calls inside some of the library's inner loops.)
-
-To establish a progress-monitor callback, create a struct jpeg_progress_mgr,
-fill in its progress_monitor field with a pointer to your callback routine,
-and set cinfo->progress to point to the struct. The callback will be called
-whenever cinfo->progress is non-NULL. (This pointer is set to NULL by
-jpeg_create_compress or jpeg_create_decompress; the library will not change
-it thereafter. So if you allocate dynamic storage for the progress struct,
-make sure it will live as long as the JPEG object does. Allocating from the
-JPEG memory manager with lifetime JPOOL_PERMANENT will work nicely.) You
-can use the same callback routine for both compression and decompression.
-
-The jpeg_progress_mgr struct contains four fields which are set by the library:
- long pass_counter; /* work units completed in this pass */
- long pass_limit; /* total number of work units in this pass */
- int completed_passes; /* passes completed so far */
- int total_passes; /* total number of passes expected */
-During any one pass, pass_counter increases from 0 up to (not including)
-pass_limit; the step size is usually but not necessarily 1. The pass_limit
-value may change from one pass to another. The expected total number of
-passes is in total_passes, and the number of passes already completed is in
-completed_passes. Thus the fraction of work completed may be estimated as
- completed_passes + (pass_counter/pass_limit)
- --------------------------------------------
- total_passes
-ignoring the fact that the passes may not be equal amounts of work.
-
-When decompressing, pass_limit can even change within a pass, because it
-depends on the number of scans in the JPEG file, which isn't always known in
-advance. The computed fraction-of-work-done may jump suddenly (if the library
-discovers it has overestimated the number of scans) or even decrease (in the
-opposite case). It is not wise to put great faith in the work estimate.
-
-When using the decompressor's buffered-image mode, the progress monitor work
-estimate is likely to be completely unhelpful, because the library has no way
-to know how many output passes will be demanded of it. Currently, the library
-sets total_passes based on the assumption that there will be one more output
-pass if the input file end hasn't yet been read (jpeg_input_complete() isn't
-TRUE), but no more output passes if the file end has been reached when the
-output pass is started. This means that total_passes will rise as additional
-output passes are requested. If you have a way of determining the input file
-size, estimating progress based on the fraction of the file that's been read
-will probably be more useful than using the library's value.
-
-
-Memory management
------------------
-
-This section covers some key facts about the JPEG library's built-in memory
-manager. For more info, please read structure.txt's section about the memory
-manager, and consult the source code if necessary.
-
-All memory and temporary file allocation within the library is done via the
-memory manager. If necessary, you can replace the "back end" of the memory
-manager to control allocation yourself (for example, if you don't want the
-library to use malloc() and free() for some reason).
-
-Some data is allocated "permanently" and will not be freed until the JPEG
-object is destroyed. Most data is allocated "per image" and is freed by
-jpeg_finish_compress, jpeg_finish_decompress, or jpeg_abort. You can call the
-memory manager yourself to allocate structures that will automatically be
-freed at these times. Typical code for this is
- ptr = (*cinfo->mem->alloc_small) ((j_common_ptr) cinfo, JPOOL_IMAGE, size);
-Use JPOOL_PERMANENT to get storage that lasts as long as the JPEG object.
-Use alloc_large instead of alloc_small for anything bigger than a few Kbytes.
-There are also alloc_sarray and alloc_barray routines that automatically
-build 2-D sample or block arrays.
-
-The library's minimum space requirements to process an image depend on the
-image's width, but not on its height, because the library ordinarily works
-with "strip" buffers that are as wide as the image but just a few rows high.
-Some operating modes (eg, two-pass color quantization) require full-image
-buffers. Such buffers are treated as "virtual arrays": only the current strip
-need be in memory, and the rest can be swapped out to a temporary file.
-
-If you use the simplest memory manager back end (jmemnobs.c), then no
-temporary files are used; virtual arrays are simply malloc()'d. Images bigger
-than memory can be processed only if your system supports virtual memory.
-The other memory manager back ends support temporary files of various flavors
-and thus work in machines without virtual memory. They may also be useful on
-Unix machines if you need to process images that exceed available swap space.
-
-When using temporary files, the library will make the in-memory buffers for
-its virtual arrays just big enough to stay within a "maximum memory" setting.
-Your application can set this limit by setting cinfo->mem->max_memory_to_use
-after creating the JPEG object. (Of course, there is still a minimum size for
-the buffers, so the max-memory setting is effective only if it is bigger than
-the minimum space needed.) If you allocate any large structures yourself, you
-must allocate them before jpeg_start_compress() or jpeg_start_decompress() in
-order to have them counted against the max memory limit. Also keep in mind
-that space allocated with alloc_small() is ignored, on the assumption that
-it's too small to be worth worrying about; so a reasonable safety margin
-should be left when setting max_memory_to_use.
-
-If you use the jmemname.c or jmemdos.c memory manager back end, it is
-important to clean up the JPEG object properly to ensure that the temporary
-files get deleted. (This is especially crucial with jmemdos.c, where the
-"temporary files" may be extended-memory segments; if they are not freed,
-DOS will require a reboot to recover the memory.) Thus, with these memory
-managers, it's a good idea to provide a signal handler that will trap any
-early exit from your program. The handler should call either jpeg_abort()
-or jpeg_destroy() for any active JPEG objects. A handler is not needed with
-jmemnobs.c, and shouldn't be necessary with jmemansi.c or jmemmac.c either,
-since the C library is supposed to take care of deleting files made with
-tmpfile().
-
-
-Memory usage
-------------
-
-Working memory requirements while performing compression or decompression
-depend on image dimensions, image characteristics (such as colorspace and
-JPEG process), and operating mode (application-selected options).
-
-As of v6b, the decompressor requires:
- 1. About 24K in more-or-less-fixed-size data. This varies a bit depending
- on operating mode and image characteristics (particularly color vs.
- grayscale), but it doesn't depend on image dimensions.
- 2. Strip buffers (of size proportional to the image width) for IDCT and
- upsampling results. The worst case for commonly used sampling factors
- is about 34 bytes * width in pixels for a color image. A grayscale image
- only needs about 8 bytes per pixel column.
- 3. A full-image DCT coefficient buffer is needed to decode a multi-scan JPEG
- file (including progressive JPEGs), or whenever you select buffered-image
- mode. This takes 2 bytes/coefficient. At typical 2x2 sampling, that's
- 3 bytes per pixel for a color image. Worst case (1x1 sampling) requires
- 6 bytes/pixel. For grayscale, figure 2 bytes/pixel.
- 4. To perform 2-pass color quantization, the decompressor also needs a
- 128K color lookup table and a full-image pixel buffer (3 bytes/pixel).
-This does not count any memory allocated by the application, such as a
-buffer to hold the final output image.
-
-The above figures are valid for 8-bit JPEG data precision and a machine with
-32-bit ints. For 9-bit to 12-bit JPEG data, double the size of the strip
-buffers and quantization pixel buffer. The "fixed-size" data will be
-somewhat smaller with 16-bit ints, larger with 64-bit ints. Also, CMYK
-or other unusual color spaces will require different amounts of space.
-
-The full-image coefficient and pixel buffers, if needed at all, do not
-have to be fully RAM resident; you can have the library use temporary
-files instead when the total memory usage would exceed a limit you set.
-(But if your OS supports virtual memory, it's probably better to just use
-jmemnobs and let the OS do the swapping.)
-
-The compressor's memory requirements are similar, except that it has no need
-for color quantization. Also, it needs a full-image DCT coefficient buffer
-if Huffman-table optimization is asked for, even if progressive mode is not
-requested.
-
-If you need more detailed information about memory usage in a particular
-situation, you can enable the MEM_STATS code in jmemmgr.c.
-
-
-Library compile-time options
-----------------------------
-
-A number of compile-time options are available by modifying jmorecfg.h.
-
-The IJG code currently supports 8-bit to 12-bit sample data precision by
-defining BITS_IN_JSAMPLE as 8, 9, 10, 11, or 12.
-Note that a value larger than 8 causes JSAMPLE to be larger than a char,
-so it affects the surrounding application's image data.
-The sample applications cjpeg and djpeg can support deeper than 8-bit data
-only for PPM and GIF file formats; you must disable the other file formats
-to compile a 9-bit to 12-bit cjpeg or djpeg. (install.txt has more
-information about that.)
-Run-time selection and conversion of data precision are currently not
-supported and may be added later.
-Exception: The transcoding part (jpegtran) supports all settings in a
-single instance, since it operates on the level of DCT coefficients and
-not sample values.
-(If you need to include an 8-bit library and a 9-bit to 12-bit library for
-compression or decompression in a single application, you could probably do
-it by defining NEED_SHORT_EXTERNAL_NAMES for just one of the copies. You'd
-have to access the 8-bit and the 9-bit to 12-bit copies from separate
-application source files. This is untested ... if you try it, we'd like to
-hear whether it works!)
-
-Note that the standard Huffman tables are only valid for 8-bit data precision.
-If you selected more than 8-bit data precision, cjpeg uses arithmetic coding
-by default. The Huffman encoder normally uses entropy optimization to
-compute usable tables for higher precision. Otherwise, you'll have to
-supply different default Huffman tables. You may also want to supply your
-own DCT quantization tables; the existing quality-scaling code has been
-developed for 8-bit use, and probably doesn't generate especially good tables
-for 9-bit to 12-bit.
-
-The maximum number of components (color channels) in the image is determined
-by MAX_COMPONENTS. The JPEG standard allows up to 255 components, but we
-expect that few applications will need more than four or so.
-
-On machines with unusual data type sizes, you may be able to improve
-performance or reduce memory space by tweaking the various typedefs in
-jmorecfg.h. In particular, on some RISC CPUs, access to arrays of "short"s
-is quite slow; consider trading memory for speed by making JCOEF, INT16, and
-UINT16 be "int" or "unsigned int". UINT8 is also a candidate to become int.
-You probably don't want to make JSAMPLE be int unless you have lots of memory
-to burn.
-
-You can reduce the size of the library by compiling out various optional
-functions. To do this, undefine xxx_SUPPORTED symbols as necessary.
-
-You can also save a few K by not having text error messages in the library;
-the standard error message table occupies about 5Kb. This is particularly
-reasonable for embedded applications where there's no good way to display
-a message anyway. To do this, remove the creation of the message table
-(jpeg_std_message_table[]) from jerror.c, and alter format_message to do
-something reasonable without it. You could output the numeric value of the
-message code number, for example. If you do this, you can also save a couple
-more K by modifying the TRACEMSn() macros in jerror.h to expand to nothing;
-you don't need trace capability anyway, right?
-
-
-Portability considerations
---------------------------
-
-The JPEG library has been written to be extremely portable; the sample
-applications cjpeg and djpeg are slightly less so. This section summarizes
-the design goals in this area. (If you encounter any bugs that cause the
-library to be less portable than is claimed here, we'd appreciate hearing
-about them.)
-
-The code works fine on ANSI C, C++, and pre-ANSI C compilers, using any of
-the popular system include file setups, and some not-so-popular ones too.
-See install.txt for configuration procedures.
-
-The code is not dependent on the exact sizes of the C data types. As
-distributed, we make the assumptions that
- char is at least 8 bits wide
- short is at least 16 bits wide
- int is at least 16 bits wide
- long is at least 32 bits wide
-(These are the minimum requirements of the ANSI C standard.) Wider types will
-work fine, although memory may be used inefficiently if char is much larger
-than 8 bits or short is much bigger than 16 bits. The code should work
-equally well with 16- or 32-bit ints.
-
-In a system where these assumptions are not met, you may be able to make the
-code work by modifying the typedefs in jmorecfg.h. However, you will probably
-have difficulty if int is less than 16 bits wide, since references to plain
-int abound in the code.
-
-char can be either signed or unsigned, although the code runs faster if an
-unsigned char type is available. If char is wider than 8 bits, you will need
-to redefine JOCTET and/or provide custom data source/destination managers so
-that JOCTET represents exactly 8 bits of data on external storage.
-
-The JPEG library proper does not assume ASCII representation of characters.
-But some of the image file I/O modules in cjpeg/djpeg do have ASCII
-dependencies in file-header manipulation; so does cjpeg's select_file_type()
-routine.
-
-The JPEG library does not rely heavily on the C library. In particular, C
-stdio is used only by the data source/destination modules and the error
-handler, all of which are application-replaceable. (cjpeg/djpeg are more
-heavily dependent on stdio.) malloc and free are called only from the memory
-manager "back end" module, so you can use a different memory allocator by
-replacing that one file.
-
-The code generally assumes that C names must be unique in the first 15
-characters. However, global function names can be made unique in the
-first 6 characters by defining NEED_SHORT_EXTERNAL_NAMES.
-
-More info about porting the code may be gleaned by reading jconfig.txt,
-jmorecfg.h, and jinclude.h.
-
-
-Notes for MS-DOS implementors
------------------------------
-
-The IJG code is designed to work efficiently in 80x86 "small" or "medium"
-memory models (i.e., data pointers are 16 bits unless explicitly declared
-"far"; code pointers can be either size). You may be able to use small
-model to compile cjpeg or djpeg by itself, but you will probably have to use
-medium model for any larger application. This won't make much difference in
-performance. You *will* take a noticeable performance hit if you use a
-large-data memory model (perhaps 10%-25%), and you should avoid "huge" model
-if at all possible.
-
-The JPEG library typically needs 2Kb-3Kb of stack space. It will also
-malloc about 20K-30K of near heap space while executing (and lots of far
-heap, but that doesn't count in this calculation). This figure will vary
-depending on selected operating mode, and to a lesser extent on image size.
-There is also about 5Kb-6Kb of constant data which will be allocated in the
-near data segment (about 4Kb of this is the error message table).
-Thus you have perhaps 20K available for other modules' static data and near
-heap space before you need to go to a larger memory model. The C library's
-static data will account for several K of this, but that still leaves a good
-deal for your needs. (If you are tight on space, you could reduce the sizes
-of the I/O buffers allocated by jdatasrc.c and jdatadst.c, say from 4K to
-1K. Another possibility is to move the error message table to far memory;
-this should be doable with only localized hacking on jerror.c.)
-
-About 2K of the near heap space is "permanent" memory that will not be
-released until you destroy the JPEG object. This is only an issue if you
-save a JPEG object between compression or decompression operations.
-
-Far data space may also be a tight resource when you are dealing with large
-images. The most memory-intensive case is decompression with two-pass color
-quantization, or single-pass quantization to an externally supplied color
-map. This requires a 128Kb color lookup table plus strip buffers amounting
-to about 40 bytes per column for typical sampling ratios (eg, about 25600
-bytes for a 640-pixel-wide image). You may not be able to process wide
-images if you have large data structures of your own.
-
-Of course, all of these concerns vanish if you use a 32-bit flat-memory-model
-compiler, such as DJGPP or Watcom C. We highly recommend flat model if you
-can use it; the JPEG library is significantly faster in flat model.

-## ------ ##
-## Usage. ##
-## ------ ##
-
-# This file is a library for parsing options in your shell scripts along
-# with assorted other useful supporting features that you can make use
-# of too.
-#
-# For the simplest scripts you might need only:
-#
-# #!/bin/sh
-# . relative/path/to/funclib.sh
-# . relative/path/to/options-parser
-# scriptversion=1.0
-# func_options ${1+"$@"}
-# eval set dummy "$func_options_result"; shift
-# ...rest of your script...
-#
-# In order for the '--version' option to work, you will need to have a
-# suitably formatted comment like the one at the top of this file
-# starting with '# Written by ' and ending with '# warranty; '.
-#
-# For '-h' and '--help' to work, you will also need a one line
-# description of your script's purpose in a comment directly above the
-# '# Written by ' line, like the one at the top of this file.
-#
-# The default options also support '--debug', which will turn on shell
-# execution tracing (see the comment above debug_cmd below for another
-# use), and '--verbose' and the func_verbose function to allow your script
-# to display verbose messages only when your user has specified
-# '--verbose'.
-#
-# After sourcing this file, you can plug processing for additional
-# options by amending the variables from the 'Configuration' section
-# below, and following the instructions in the 'Option parsing'
-# section further down.
-
-## -------------- ##
-## Configuration. ##
-## -------------- ##
-
-# You should override these variables in your script after sourcing this
-# file so that they reflect the customisations you have added to the
-# option parser.
-
-# The usage line for option parsing errors and the start of '-h' and
-# '--help' output messages. You can embed shell variables for delayed
-# expansion at the time the message is displayed, but you will need to
-# quote other shell meta-characters carefully to prevent them being
-# expanded when the contents are evaled.
-usage='$progpath [OPTION]...'
-
-# Short help message in response to '-h' and '--help'. Add to this or
-# override it after sourcing this library to reflect the full set of
-# options your script accepts.
-usage_message="\
- --debug enable verbose shell tracing
- -W, --warnings=CATEGORY
- report the warnings falling in CATEGORY [all]
- -v, --verbose verbosely report processing
- --version print version information and exit
