Digital Signature Presentation

Like to ask how to change the presentation of digital signature rendered on PDF?
If I were to use the method, pdfSign.sign(1, true, rect, signature);… I will get ugly “undefined” on the Contact and Location fields.

This is generated using Aspose. Note the ugly “undefined” fields…

There are multiple Sign members of the PdfFileSignature instance. You can define reason, contact and location, etc. Kindly send us your source PDF and the signature file along with the password. We will investigate and share our findings with you.
