2021-11-04Add QIntC::range_check_subtractJay Berkenbilt
2021-11-04Check object ownership when addingJay Berkenbilt
When adding a QPDFObjectHandle to an array or dictionary, if possible, check if the new object belongs to the same QPDF. This makes it much easier to find incorrect code than waiting for the situation to be detected when the file is written.
2021-11-03Make QPDF::findPage public (fixes #516)Jay Berkenbilt
This was originally not public because I wanted to get rid fo the pages cache, but I recently realized there were deep reasons not to do that, and the author of pikepdf wanted this, so I decided to make it public.

2021-03-03Fix behavior for finding /Q, /DA, and /DR for form fieldsJay Berkenbilt
If not found in the field hierarchy, /Q and /DA are supposed to be looked up in the document-level form dictionary. /DR is supposed to only come from the document dictionary.
2021-02-25Have QPDFObjectHandle notice when replaceObject was calledJay Berkenbilt
This results in a performance penalty of 1% to 2% when replaceObject and swapObjects are never called and a somewhat larger penalty if they are called, but it's worth it to avoid very confusing behavior as discussed in depth in qpdf#507.

2021-02-06Remove erroneous handling of /EFF for stream decryptionJay Berkenbilt
I thought /EFF was supposed to be used as a default for decrypting embedded file streams, but actually it's supposed to be advice to a conforming writer about handling new ones. This makes sense since the findAttachmentStreams code, which is not actually needed, was never right.
2021-02-03Handle older PDFs whose form XObjects inherit resources (fixes #494)Jay Berkenbilt
When removing unreferenced resources, notice if a page (recursively) contains a form XObject with unreferenced resources, and count any such resources as referenced by the page.
