Hi all,
> Please, send a patch, will make everyone lives easier. And also send a PDF > and some code to prove your patch has benefits at least for a given case. > > Albert > as it was not as clear as possible in the first message, I want to clarify that the problem is in saving a modified file incrementally by giving writeForceIncremental flag to PDFDoc->saveAs. The problem occurs only if the file is linearized. I attached a patch, which modifies the original behaviour of getStartXRef for the case that the file is linearized. With the patch applied my application modifies the file okay. I also attached the original (test2.pdf) and modified files before and after applying the patch, respectively. openTest.pl uses CAM::PDF and demonstate my problem. It opens test2.pdf and test2-afterPatch.pdf okay but not test2-beforePatch.pdf If I could assist you any further don't hesitate to contact me. -- regards Axel
