I need to crop a few pdf files, to create four pages from each source page. I know, hot to do that with ImageMagick, but it can't work with vector images, which pdf is, so the resulting quality is far from good. Is there any programme, which would let me do this and not lose image (mostly,text, actually) quality?
EDIT: I want this. I have a pdf file, created from a presentation, and each page of it contains 4 slides from a presentation.
I want each of these pages to became a separate page.
