Provides access to a signature appearance object. Use it to customize the appearance of the signature.

Be aware:

If you create new signature field (either use SetFieldName(System.String) with the name that doesn't exist in the document or don't specify it at all) then the signature is invisible by default.
If you sign already existing field, then the signature appearance object is modified to have all the properties (page num., rect etc.) consistent with the state of the field (if you customized the appearance object before the SetFieldName(System.String) call you'll have to do it again)

PdfSignatureAppearance object.
