Yet more fun with iText and PDF signing from me. I have a simple PDF with a simple signature field. That signature field has the /TU entry set but after it has been signed with iText the newly filled signature field does not contain the /TU entry any more. The result is the same with a new revision (PdfStamper.createSignature(..., true)) and without ((PdfStamper.createSignature(..., false)).
The Acrobat carries all field dictionary entries over to the filled field (including any third party attributes that start with /XX), but iText dosn't. I use createSignature() and then set the signature name with setVisibleSignature() to that of the empty field to fill it. Is there another way to fill signature fields or can I somehow manually add additional dictinary attributes to the signature field just before I do the close/preclose? I attached a PDF and the results with new revision(true) and without(false) -Robert
