Hi all. After a couple of days triyng about, and read many posts, I'm unable to add a watermark to a existing signed PDF without broken it. In Adobe reader the signature appears broken, with error "byte range is invalid".
I know that this can be posible, because I have done it manually though Adobe Acrobat Profesional. (Document->Watermark->Add). I have open "pdf_signed.pdf" file, and add a watermark to every page of it, saving the result file to ""pdf_signed_and_watermarked.pdf". I have compared both two files, pdf_signed.pdf and Acrobat resultant "pdf_signed_and_watermarked.pdf", and the latest is identical byte to byte to the original one, but with a added content. As if the added content act as a "revision" or "upgrade" of the original document. My question: How can I make this with iText ?? If iText can't: There are another library that I can use? thanks ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ iText-questions mailing list iText-questions@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.1t3xt.com/docs/book.php
