I have a program in Python (using pyPDF) that merges a bunch of different PDF documents. Sometimes, the resulting pdf is fine, except for some blank pages in the middle. When I view these documents with Acrobat Reader, I get an error message saying "insufficient data for image". When I view the documents with FoxIT Reader, I get some blank pages and a munged image.
The only odd thing about the PDF that creates the blank pages is that it seems to be PDF Version 1.4, and PyPdf seems to create files with PDF Version 1.3.
1) Does the version thing sound like the root cause of my problem?
2) Is there a way to get PyPdf to handle this correctly?
