Flattening document with esignature deletes signature

When flattening a document with esignature the signature gets removed. Digital signatures remain, but esignatures do not.

Hello Gary,

Thank you very much for the provided context and details. That said I am still unable to reproduce anything resembling this scenario on my end, so it would be much appreciated if you could provide us with something to inspect. As mentioned, some sample documents should be sufficient, but if you could also share a code snipped or a full project reproducing this case it would make it way more convenient.

Once again please rest assured that all resources shared by you will be treated with privacy and used only towards resolving this case.

Let me know if you need anything in the meantime.

Regards,

We are merging several documents for viewing and printing. This does not change the original document, so no worries about invalidating the signatures. In the process we are also stamping them with a header. It seems adding this required use of RadFixedPage. Using this though resulted in emptying any fillable forms as well as removing signatures. If we flatten the file before stamping the header, those items are imprinted on the page, in a read-only way. Digital signatures still appear, but e-signatures do not. When I say e-signature I mean the one that looks like the person actually scribbled their name on the page.

Hello Gary,

Usually flattening a document is considered modifying it, which by default nullifies the validity of a signature. Also, I might be misunderstanding the case so can you clarify what you mean by a signature 'being removed' and what are the exact final results you are expecting to see?

That said, in order for me to get a better context and understanding of this case, would you be able to share with us an example document(s) that reproduce this behavior? That way I can try to achieve the same scenario you are experiencing, examine the resources, and get back to you with details and specifics. I can assure you that anything shared by our clients is treated with strict confidentiality and is used for testing purposes only (as per our EULA section 11).

Looking forward to your reply.
