PDF/A-2 Problem

Aspose.PDF Product Family

Hello!

I have a very specific problem with documents that are converted to PDF/A-2 format.
When I sign the PDF/A-2 pdf using a signature service (eg PDF Sign | A-Trust), the first signature is broken if i sign it twice.
Attachted is the PDF/A-2 pdf htmlEncoding.htm.pdf (52.0 KB), after it was signed using the mentioned signature service signature1.pdf (127.6 KB), and after it was signed the second time using the same service signature2.pdf (203.2 KB)

As you can see, the first signature is broken in signature2.pdf, which does not happen, if the pdf was not converted to pdf/A-2 using Aspose.PDF.

I might be, that the signature service is the problem here, but we did not have any problems with it before I switched to PDF/A-2 conversion, therefore the conversion to PDF/A-2 is suspected a bit.

Can you please check if this is an Aspose-specific problem.

Kind regards
