We are currently looking at the Gnostice product that offers feature of filling digital signature to an empty e-signature pdf form field. We use the Digital Signature demo to test out the functionality using our PDF form, but all we got from the output is blank signed form. The properties of the signature indicates it is signed correctly, but it's blank on the form. We would like to know what is causing this. Also, our PDF form has 3 digital signature form fields. 2 of them are filled by our customers, but the 3rd one we need to sign. The 2 valid signed e-signatures when processed through the Digital Signature demo, they became invalid.

PDFtoolkit VCL 2.5 has introduced a new method that will help you extract. Old feature of PDFtoolkit that allowed users to add attachments to a PDF document. PDFtoolkit hides the complexity of the PDF format and allows developers to easily create applications that can edit, enhance, secure, merge, split, view, digitally sign, and print PDF documents and process PDF forms. PDFtoolkit can extract text, export to images, and also add digital signatures. Wow god mode cheats.

We also want to know what is causing this as well. We need the two functionality because we will be processing thousands of PDF per month. Our IDE is Delphi 7, windows xp 32 bit, using PDFToolKit VCL v4.0.1.145.
