I have renewed our Developer Support contract, but the paid support page still says expired.
We need to prevent our customers editing the pdf files that we send to them.
Our customers will not accept any file that requires a signature or password. We, therefore, need to make our pdfs a little more difficult to edit.
I use doc.flatten to flatten form fields on the pdfs, but I can still edit them in Adobe Acrobat Pro DC. When I select tools-Forms Adobe Acrobat finds all the text and image fields.
I have attached a typical pdf file that we send to customers.
Thank you
Derek Williams
