Page.insert_box：If the text has too many characters, it will not be displayed completely.

Description of the bug

t1 = "text with rotate = 0.can't see me"，Can't display...

import fitz

doc = fitz.open()  # new or existing PDF
page = doc.new_page()  # new page, or choose doc[n]

# write in this overall area
rect = fitz.Rect(100, 100, 300, 150)

# partition the area in 4 equal sub-rectangles
CELLS = fitz.make_table(rect, cols=4, rows=1)

t1 = "text with rotate = 0.can't see me"  # these texts we will written
t2 = "text with rotate = 90."
t3 = "text with rotate = 180."
t4 = "text with rotate = 270."
text = [t1, t2, t3, t4]
red = fitz.pdfcolor["red"]  # some colors
gold = fitz.pdfcolor["gold"]
blue = fitz.pdfcolor["blue"]

shape = page.new_shape()  # create Shape
for i in range(len(CELLS[0])):
    shape.draw_rect(CELLS[0][i])  # draw rectangle
    shape.insert_textbox(
        CELLS[0][i], text[i], fontname="hebo", color=blue, rotate=90 * i
    )

shape.finish(width=0.3, color=red, fill=gold)
shape.commit()  # write all stuff to the page
doc.save("D:/tst/xxx.pdf")

This is normal!
And also documented.

If you do not want to care about whether something fits or not, use page.insert_htmlbox instead.

[LittleMoDel]

page.insert_htmlbox，and doc.subset_fonts() like this:

import fitz_new as fitz

# Example text
text = """
    <p>Hello World!</p>
    <p class="a">你好世界！</p>
    <span class="b">你好世界！我是span！</span>
    """
arch = fitz.Archive("D:/")
# These statements define which font file to use for regular, bold,
# italic and bold-italic text.
# We assign an arbitary common font-family for all 4 font files.
# The Story algorithm will select the right file as required.
# We request to use "comic" throughout the text.
css = """
@font-face {font-family: 'SimSun-ExtB Regular'; src: url(simsunb_reduce.ttf);}
@font-face {font-family: 'Arial Regular'; src: url(arial_reduce.ttf);}
@font-face {font-family: 'XinYuGongZhangJiaSongA'; src: url(OPPOSans.ttf);}
* {font-family: 'Arial Regular';}
.a {font-family: 'XinYuGongZhangJiaSongA';}
.b {font-family: 'SimSun-ExtB Regular';}
"""

doc = fitz.Document()
page = doc.new_page(width=300, height=300)  # make small page

page.insert_htmlbox(page.rect, text, css=css, archive=arch)

doc.subset_fonts(verbose=True)  # build subset fonts to reduce file size
doc.save("D:/123_new.pdf")

Is this normal？

[JorjMcKie]

Yes - set verbose to False if you don't want to see the messages.

Your save statement however is too careless!
Subset font building leaves the old large font there - you must compress!!!
doc.ez_save(...) has the necessary options.

[LittleMoDel]

doc.ez_save(...) Thank you very much!

'NotoSerif-Regular' and 'Droid Sans Fallback Regular',I did not set these two font.
I figure out the "SimSun-ExtB Regular" not support chinese,so that replaced by 'Droid Sans Fallback Regular'!
but 'NotoSerif-Regular' , I can‘t undestand...

[JorjMcKie]

but NotoSerif-Regular , I can't undestand...

This is one of MuPDF's default fonts when no other font-family name is applicable. Depending on the Unicodes encountered, either "NotoSerif-Regular" is chosen or "CharisSIL-Serif..." in such a case.
You must be using a Unicode that is not contained in any of the given fonts ...

But you can find out yourself what has happened: extract the text via "dict" or "rawdict" (respectively "json"/"rawjson") and you will which font has been used for what.

[LittleMoDel]

I have something can't handle about page.insert_htmlbox, code :

import fitz_new as fitz
doc = fitz.open("C:/tst/old.pdf") # open document
page = doc[0] # get the 1st page of the document
rect2=fitz.Rect(100,156,220,170)

text = """<div class="cs">分切尺寸：200*300mm</div>"""
arch = fitz.Archive("D:/")
CSS = """
@font-face {font-family: 'simsun'; src: url(simsun.ttc);}
@font-face {font-family: 'arial'; src: url(arial.ttf);}
# @font-face {font-family: 'OPPOSans'; src: url(OPPOSans.ttf);}

* {
    font-family: 'simsun',sans-serif;
    font-size:7.98pt;
    color:red;
    margin:0px;
    padding:0px;
    border-width:0px;
}
.cs {
    font-family: arial,sans-serif;
    # font-size:7.98pt;
}
"""
page.insert_htmlbox(
    rect2, 
    text, 
    css=CSS, 
    archive=arch,
    rotate=0,
    )
print(page.get_text("dict", sort=False))
doc.subset_fonts(verbose=True)
doc.ez_save("C:/tst/new.pdf")
doc.close()

I want the text start at x0=100, but I runned the code above ,It gives me

[{'size': 7.980000019073486, 'flags': 4, 'font': 'SimSun', 'color': 16711680, 'ascender': 0.859375, 'descender': -0.140625, 'text': '分切尺寸：200*300mm', 'origin': (101.0, 164.1820068359375), 'bbox': (101.0, 157.32418823242188, 176.8100128173828, 165.30419921875)}]

The text just starts at the 101 !

And I changed html tag: text = """<div class="cs">分切尺寸：200*300mm</div>""" to text = """<p class="cs">分切尺寸：200*300mm</p>""",

It gives me another position,and the fontsize=6.359182357788086.....:

[{'size': 6.359182357788086, 'flags': 4, 'font': 'SimSun', 'color': 16711680, 'ascender': 0.859375, 'descender': -0.140625, 'text': '分切尺寸：200*300mm', 'origin': (100.79689025878906, 168.0823974609375), 'bbox': (100.79689025878906, 162.6174774169922, 161.20912170410156, 168.97665405273438)}]
