I have a PDF document that can be any size and I would like to burn in or insert a trim box into that PDF using PHP. Possibly with Imagemagick but do not know the command to run (not sure if one even exists)
I did a lot of searching and havent found anything that answers my question so I am hoping someone may know. I would provide code but I do not even know what commands to use to provide any code of what I have tried. Any help please?
