Hello, It's me again with more problems regarding NeedAppearances. Yesterday I thought removing it would solve my problem (thanks to Mark Storer for the code and the warning about it being document-level) and it indeed makes the new signature visible but it also makes all the empty fields invisble in the "Signatures" tab (Acrobat). I've spent some time looking at what the Acrobat does and what iText does and just wanted to check if I understood it right.
I have a PDF with 2+ empty signature fields. The PDF was created by adding eps files with pdfmarks code in an office document and converting them with distiller/ghostscript. The resulting PDF contains empty signature fields. BUT the PDF also contains the NeedAppearances flag. This causes the Acrobat to ask me if I want to save the document whenever I close it (even if I do nothing). Doing so causes the Acrobat to rebuild all signature fields. The resulting PDF looks identical to the old one but a) doesn't contain the NeedApperances Flag and b) now contains "real" objects (whatever that means). The saved document works fine with iText. BUT the unsaved (= newly created) PDF doesn't work with itext. One problem is that I can't seem to find any form fields (.getFields() and .getBlankSignatureNames() are epmty). Once I add an empty object using: PdfFormField field = PdfFormField.createEmpty(stp.getWriter()); stp.addAnnotation(field, 1); stp.close(); I can find all fields just fine. The other problem is that once I fill one field I have two possible outcomes (both of which are bad): a) I remove the NeedAppearance flag -> the new signature is visible, all other dissapear B) I leave the NeedAppearance and have an "invisible" signature. So, in order to make it work with iText I have to iterate through all fields and rebuild them into "real" objects before I save sign the PDF for the first time!? For now I can probably do this by reading the old signature fields properties, deleting it and creating a new one with the old ones properties (haven't tried it yet). But this won't cover other types of fiels. So the million dollar question is: Is there a way to tell iText to rebuild the appearance for all objects like the Acrobat does when you save it? Sorry for all the long text but this problem really got me worked up :( Any tips would be appreciated, -Robert
