AB,
I have seen the closed ticket, just one note:
I am not sure if you have realized that electronic signature differs from digital. It just inserts the scanned signature as a picture, but after the document is saved it is not supposed to be editable any more. So it may not be very difficult to implement.

Yes, tickets are for bug reports, after discussion in the forum.
They are not the place to discuss.
You can create a PDF with a signature, then save it as PDF/A-1 so that it will be not editable any more.
But to add such a picture to an existing pdf, you will need to read the pdf, which is a feature not available yet with SynPDF.

I guess if each page of the original file can be converted to an image (instead of single PDF) the images can be used for recreating your document with SynPDF and sign it the way AB suggested. The size probably will be larger though.
displaying the PDF:
AcrobatReader with OLE
OR
Delphi - Winsoft PDFium
Lazarus - MuPDF
It is possible that you can sign a PDF with these as well.

So SynPDf can be used for electronic signature already.
Thanks!
