Can I add a watermark to a pdf doc generated from a docx file and signed digitally

[Nick]

Hello,

I would like to ask if I can add watermark to a pdf document generated from a docx file and signed digitally without invalidating the signature.

 

 

Thank you

Hello Nick,

Modifying a PDF document in any way invalidates its signature by default, so it won't be possible to meet the requirements you are describing. That being said, if you are still interested in adding a watermark, in the Add Watermark Example you can find how this can be achieved by utilizing the drawing capabilities of RadPdfProcessing.

If there is anything else you might need assistance with, we are at your disposal.
