Question: I have two PDF or postscript files (I can work with either one). What I want to do is merge each page on top of the other so that page1 of document A will be combined with page 1 of document B to produce page 1 of the output document. This isn't something I necessarily want need to do programmatically, although that would be helpful. Is there any solution one VeryPDF?
