MuPDF bug id: https://bugs.ghostscript.com/show_bug.cgi?id=707947. |
@JorjMcKie This has been fixed upstream, can can be marked "fix developed", right? |
This issue also needs a fix to PyMuPDF itself which i don't think has been done yet, so |

Description of the bug
The attached PDF page uses a font which ascender value is incorrectly determined by MuPDF.
Basis of this post is Discussions post #3772.
How to reproduce the bug
The revealing command is
mutool draw -o test.xml -F stext test.pdf
.test.pdf
The problematic font is "AdvOT144a03c1" (embedded subset).
Note that this error happens in MuPDF, not PyMuPDF. So we assign the label "upstream bug".
However, PyMuPDF's Page method
get_text("dict")
does not correctly repair the computation when settingTOOLS.set_small_glyph_heights(True)
. So we also assign the label (PyMuPDF) "enhancement".PyMuPDF version
1.24.9
Operating system
Windows
Python version
3.12
