Could you let me know if the font color of the text in the below PDF can be changed to a different color using PyMuPDF and how it can be done?

No this is not possible to do.

Thanks a lot

[meghanaviyyapu]

Would the approach work for any font type and any language?

[JorjMcKie]

I currently see no reason why not ...

Have tried the above code to modify color in the PDF but getting error with font. Could you let me know how it can be resolved

This is the PDF for which I tried changing color

Please consult the documentation for the Font class. Creating an Font object requires either string that represents the name of one of the fonts built into PyMuPDF (like "helv", "tiro" or -if package pymupdf-fonts is installed - names like "ubuntu" and more), or a font name or font buffer (both specified via arguments fontfile, respectively fontbuffer.
Your argument "MS-Gothic" falls in none of these categories.

[JorjMcKie]

Have tried modifying the font color using the attached code but could not view any changes in the text color and could see only rectangles drawn.
Attached the code and the output PDF. Could you let me know if I missed something?
