I have been search throughly on Google and stackoverflow, but it looks like I don't find any "clear" information regarding edit existing PDF file using FPDF ...
So, what I wan't to do is add a controlled copy marking on every PDF download from my site. To do this, the file source is already PDF file, and I want to edit them using FPDF ... But this "copy marking" is not on a new page, it is on the cover document. So there is no "add new page" process.
Any clue ?
Thank you for your help.
p.s. : Sorry for my bad english :p
