SignerProcess Method

Process a document

Apply document-level processing options without any signature operation. For example:

To encrypt or decrypt PDF documents that may be signed (see the samples "Encrypt" and "Decrypt").
To remove signatures and unsigned signature fields (see RemoveSignatures).
To add validation information to existing signatures (see AddValidationInformation).

Non-critical processing errors raise a Warning. It is recommended to review the WarningCategory and handle them if necessary for the application.
