Hello,
I encounter a problem when trying to fix some problem with invalid certificate in PDF that I am processing. I have two PDFs which I am merging together. First one is some one page template where I fill soma data and second one is multiple page PDF which contains some corrupted signature. When I merge these PDF first and then try to search for corrupted signature I will get nothing from document.getDocument().getObjectsByType(COSName.SIG) since xref table of second PDF is replaced with the one from first one. I can get around it in my code but is there a possibility to keep xref table from both PDFs after merge? With best regards, Frantisek Simon
