When user tries to print PDF document we are trying to check whether there are any changes done to the document, if there are any changes need to hide the digital signature field in that PDF. Any help would be greatly appreciated.
Prior to being signed there is no concept of 'history' in a PDF file, so no way to detect modifications.
Thanks for reply. one more scenario is that if the user edits the document and tries to print it. will the above 'signatureGetModifications()' report those changes too even before saving the document.. it might feel silly, but am new to this programming..
