I am looking for a simple solution for converting a PDF file into any image format. I am trying to avoid using paid libraries.
The goal is to, after converion, show a preview of the first PDF page inside a panel. To accomplish that, I need to convert at least the first page of the file into an image format. I will have to stamp a code bar into the file, then convert it back to PDF (although this part is not the problem).
I would greatly appreciate if any of you could point me in the right direction.
