doc.need_appearances() fails with "AttributeError: module 'pymupdf.mupdf' has no attribute 'PDF_TRUE' " #3859
Description
Description of the bug
Since fitz_new has replaced the old fitz module, attempting to set the /NeedAppearances property with doc.need_appearances() results in an AttributeError. It seems the attributes PDF_TRUE and PDF_FALSE are missing from the new module.
I could reproduce this issue with PyMuPDF version 1.24.10. Notice that doc.need_appearances() used to work with fitz_old in version 1.24.1 and earlier.
How to reproduce the bug
The issue can be reproduced with this example PDF form:
http://foersom.com/net/HowTo/data/OoPdfFormExample.pdf
When attempting to set doc.need_appearances() with the snippet below:
import fitz
with fitz.open("OoPdfFormExample.pdf") as doc:
# Needed for displaying the form values when printing faxes
doc.need_appearances(True)
print("This should work")The following traceback is shown:
Traceback (most recent call last):
File "/Users/my_user/example/aaa.py", line 5, in <module>
doc.need_appearances(True)
File "/Users/my_user/Library/Caches/pypoetry/virtualenvs/example-fxn3BqgU-py3.12/lib/python3.12/site-packages/pymupdf/__init__.py", line 4944, in need_appearances
mupdf.pdf_dict_puts(form, appkey, mupdf.PDF_TRUE)
^^^^^^^^^^^^^^
AttributeError: module 'pymupdf.mupdf' has no attribute 'PDF_TRUE'
The same issue happens with PDF_FALSE as well.
