Pdf Signature C#

I’m using your PDF product, it works fine but I have a problem that I can’t find on the documentation how to do.

I’m developing software that captures handwritten signature with a Wacom or other signature tablets.

I want to sign with a digital certificate and include the handwritten signature (points, speed, pressure, etc) and use a bitmap to show.

There is no problem to sign with the certificate and use the bitmap, but I can’t find how to include the metadata at the signature.

This metadata will be extracted if needed with a program developed by my company.

Can you help me, please? It is important do not change the content of the document.
