Cannot interpret colorspace NullObject #2061
Description
I am trying to extract the images from a PDF file, but receive an error for xref object 16, while MuPDF is able to extract it.
Environment
Which environment were you using when you encountered the problem?
$ python -m platform
Linux-5.14.21-150400.24.69-default-x86_64-with-glibc2.3.4
$ python -c "import pypdf;print(pypdf.__version__)"
3.14.0Code + PDF
This is a minimal, complete example that shows the issue:
from pypdf import PdfReader
reader = PdfReader('ARK_HV_Batteriesystem_Datenblatt_DE_202304.pdf')
for page in reader.pages:
for key in reader.images.keys():
print(key)
print(reader.images[key])A publicly available PDF file which reproduces this issue for me is https://de.growatt.com/upload/file/ARK_HV_Batteriesystem_Datenblatt_DE_202304.pdf
