Wo hast Du diese Information her (mit Version 1.7)?
Auch vor 1.7 sind doch PDFs schon rechtsgültig signiert worden?

On second thought, if I have a signed PDF file in version 1.4, I won't be able to do anything with it.
I think so because the signed PDF has to be saved as a PDF in version 1.7 before it's signed.

Please let me know if I'm right.

  • My primary needs is related to :

  • "Incremental updates are required when modifying a digitally signed PDF. Any changes to the existing bytes in the file will invalidate existing signatures, so re-writing the PDF is not an option."

But also I was exptecting that if I use incremental update it means for me "versioning".
So my further question is how I can use ACROBAT READER to switch to view each subsequent version ?

I was in hope to use:

https://developers.foxit.com/developer-hub/document/incremental-updates/

My question is how to setup QPDF object to create PDF 1.7  and not PDF 1.4 ?

I see I can use:
SetPDFAMode

...a few minutes later...
found it ...
$DPL.SetInformation(0, '1.7')
