I did my research around this topic, I understand in many countries there are legal reasons of not having this. But I have a requirement and need to have display for an external signature on each page. Any working approach/snippet will be highly appreciated.

Also is it possible to help annotations on each page for an existing signature? If yes, any code snippet will be helpful.

  • *I understand in many countries there are legal reasons of not having this. But I have a requirement and need to have display for an external signature on each page.* In other words: you want to do something that will be in violation of ISO-32000-2. Or, you want to create a PDF that won't be a valid PDF 2.0 file. If that's what you want, you need to use software that doesn't obey the specs. In that case: don't expect an answer from iText developers. – Bruno Lowagie Jul 12 '16 at 08:38
  • @BrunoLowagie Unfortunately regulations of all the countries are not as quickly updated as technology. – Abhinav Parashar Jul 12 '16 at 12:46
  • Have you actually seen a PDF that looks like what you are asking for? – Chris Haas Jul 12 '16 at 13:30
  • @ChrisHaas Oh yes, its not uncommon. Checkout Appendix: Multiple appearances of a signature at http://stackoverflow.com/questions/37027579/how-to-associate-a-previous-signature-in-a-new-signature-field but I am experimenting with itext 5, couldn't make it work. – Abhinav Parashar Jul 12 '16 at 13:41
  • @AbhinavParashar As you add a link to that answer and couldn't make it work, where did you get stuck? It should be a fairly straight forward port of the code in the *Doing it in iText 5* section of the answer. That been said, if you merely need to *"have display for an external signature on each page"*, why not simply add such visual display on each page as regular content instead of trying to make a PDF AcroForm signature for that? That way you have a *"display"* on each page without any issues with the PDF format or iText. – mkl Aug 01 '16 at 11:03
