"/Pages" might be undefined #2516
Description
I am trying to get the pages of a PDF file which does not have the /Pages object, but where we have got
self.root_object == {'/Type': '/Pages', '/Kids': [IndirectObject(3, 0, 140441093721392)], '/Count': 1}and
catalog["/Kids"][0].get_object().get_data() == b'q 595.20 0 0 840.96 0.00 0.00 cm 1 g /Im1 Do Q\r'This does not seem to be properly supported at the moment.
Environment
Which environment were you using when you encountered the problem?
$ python -m platform
Linux-5.14.21-150400.24.100-default-x86_64-with-glibc2.3.4
$ python -c "import pypdf;print(pypdf._debug_versions)"
pypdf==latest Git main, crypt_provider=('local_crypt_fallback', '0.0.0'), PIL=8.4.0Code + PDF
This is a minimal, complete example that shows the issue:
from pypdf import PdfReader, PdfWriter
reader = PdfReader('file.pdf')
for page in reader.pages:
print(page)I cannot disclose the PDF file here as the referenced image holds sensitive information, but I hope that it is indeed possible to generate a basic example PDF file from the provided values above.
