No Problem
I started with ImageMagick, then PascalMagick, but ran into a few missing parts that would make it more convenient, maybe I will go back to this route once the package gets an upgrade. But after upgrading to a later version of GhostScript it ran noticably slower for some reason, which was a little strange.
Then I played around with MuPDF.
The last one was/is Xpdf. For now I will keep Xpdf.
It is an ongoing process, I try spend some (rare) free time on this subject.
