How to convert PDF files to images using RMagick and Ruby

Question

I\'d like to take a PDF file and convert it to images, each PDF page becoming a separate image.

\"Convert a .doc or .pdf to an image and display a thumbnail in Ruby?

Answer 1

Since I can't find a way to deal with PDFs on a per-page basis in RMagick, I'd recommend first splitting the PDF into pages with pdftk's burst command, then dealing with the individual pages in RMagick. This is probably less performant than an all-in-one solution, but unfortunately no all-in-one solution presents itself.

There's also PDF::Toolkit for Ruby that hooks into pdftk but I've never used it.
