Hmmm, sorry, I'm not that deep in PDF details ... a dynamic PDF is a PDF where someone filled some form with values ... isn't that the usual case for versioned signatures ? A first version signed with empty fields, a second version with new values appended, leaving the old signature intact ? And probably a second signature over it all ?
Or is this XFA stuff working completely different ? Greetings Andreas ----- original Nachricht -------- Betreff: Re: [iText-questions] Xfa signature Gesendet: Mi, 13.
