Openize.Heic.Decoder.HeicImageFrame

Heic image frame class. Contains hevc coded data or meta data.

Properties

Name	Type	Description	Notes
ID	uint	The unique identifier of the image frame.
ImageType	ImageFrameType	Type of an image frame content.
Width	uint	Width of the image frame in pixels.
Height	uint	Height of the image frame in pixels.
HasAlpha	bool	Indicates the presence of transparency of transparency layer. True if frame is linked with alpha data frame, false otherwise.
IsHidden	bool	Indicates the fact that frame is marked as hidden. True if frame is hidden, false otherwise.
IsImage	bool	Indicates the fact that frame contains image data. True if frame is image, false otherwise.
IsDerived	bool	Indicates the fact that frame contains image transform data and is inherited from another frame(-s). True if frame is derived, false otherwise.
DerivativeType	BoxType?	Indicates the type of derivative content if the frame is derived.
AuxiliaryReferenceType	AuxiliaryReferenceType	Indicates the type of auxiliary reference layer if the frame type is auxiliary.
NumberOfChannels	byte	Number of channels with color data.
BitsPerChannel	byte[]	Bits per channel with color data.

Methods

Name	Type	Description	Parameters
GetByteArray	byte[]	Get pixel data in the format of byte array. Each three or four bytes (the count depends on the pixel format) refer to one pixel left to right top to bottom line by line. Returns null if frame does not contain image data.	PixelFormat pixelFormat - Pixel format that defines the order of colors and the presence of alpha byte. Rectangle boundsRectangle - Bounds of the requested area.
GetInt32Array	int[]	Get pixel data in the format of integer array. Each int value refers to one pixel left to right top to bottom line by line. Returns null if frame does not contain image data.	PixelFormat pixelFormat - Pixel format that defines the order of colors. Rectangle boundsRectangle - Bounds of the requested area.
GetTextData	string	Get frame text data. Exists only for mime frame types.
ToString	string	Returns a string representation of the object.

Fields

Name	Type	Description	Notes
hvcConfig	HEVCDecoderConfigurationRecord	Hevc decoder configuration information from Isobmff container.
rawPixels	byte[][,]	Raw YUV pixel data, used when bit depth is less or equal 8. Multidimantional array: chroma or luma index, then two-dimentional array with x and y navigation.
rawPixelsHighColorRange	ushort[][,]	Raw YUV pixel data, used when bit depth is greater than 8. Multidimantional array: chroma or luma index, then two-dimentional array with x and y navigation.
