How to display signature field in WPF PDFViewer control?

By default, WPF PDF Viewer does not support displaying signature fields in the PDF document, the PDF document should be flattened to display the content of the signature field in the PDF viewer. Please refer to the below code snippet for achieving the same.

C#

//Load the PDF document.
PdfLoadedDocument loadedDocument = new PdfLoadedDocument("../../Data/Sample.pdf");
//Flatten the form.
loadedDocument.Form.Flatten = true;
 
MemoryStream memoryStream = new MemoryStream();
//Save the modified document.
loadedDocument.Save(memoryStream);
memoryStream.Position = 0;
 
PdfViewerControl pdfViewerControl = new PdfViewerControl();
// load the document in pdfviewercontrol
pdfViewerControl.Load(memoryStream);
