Thanks for the answer. I didn't want to go into the details and if every single feature is supported because reading through the PDF spec gives me a headache and that's why I asked here in the first place :)
The reason for my question is that we use iText to automatically sign PDF files (mostly designed for electronic bills/invoices) and wanted some degree of assurance that "normal" PDFs created by the "usual" software (eg. Acrobat 6) can be parsed and signed with iText. So far we haven't had any problems but we also can't test every single theoretically possible PDF gimmick so I was hoping someone here would know how far iText's compatibility (especially parsing) goes when it comes to the most common PDF features. So for now I'll assume that iText can handle pretty much anything the distiller can throw at me when it comes to 1.5, does that sound about right? -Robert -----Urspr�ngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Leonard Rosenthol Gesendet: Donnerstag, 9.

What's your definition of "fully"? If you are asking if iText can read & write EVERY SINGLE FEATURE of PDF 1.5 - the answer is no, it can't - but then neither can Adobe Acrobat or the Adobe PDFLibrary. iText (and the Adobe PDFLibrary) provide you access to read & write the internal PDF structures - BUT there are a variety of external data structures (XML, Font & image formats, etc.) that are permitted for inclusion/integration with PDF that those libraries don't provide "support" for (other than as a generic blob). This is the situation with XFA forms (which also existed in PDF 1.5, btw) - iText can read & write the XML as a blob. It simply doesn't do XML parsing/manipulation for it...Same, again, is true for Adobe's own libraries.
