How to get SignatureAppearanceStream from a SignatureField?

Aspose.PDF Product Family

Hello,

We are using Aspose.PDF.Drawing 24.8.0 nuget package.

When we sign a document with a SignatureField on a specific page, we set the PdfFileSignature.SignatureAppearanceStream property with an image having a specific logo. It works fine…

On the other hand, how is it possible to get only the logo from a SignatureField?

We have tried with PdfFileSignature.ExtractImage, but this method provides an image with the whole rectangle of the signature field but unfortunatly, it does not provide the small image in the background of the rectangle.

Hello,

var image = pdfFileSignature.ExtractImage(signatureField.FullName);

This is extracting an image with the whole signature (logo + text information).

What I need is only to get the logo (for example, the Acrobat logo if the signature has been certified suing Acrobat)
