I use ghostscript for batch processing of PDF and Postscript documents. It is easy to make printouts, create bitmaps, perform conversions, etc.

Ghostscript is a very active project at SourceForge

I found but have not tried a Ghostscript perl module on the news and community site for Ghostscript.

These tools are multiplatform. I have had great success with them!

It should work perfectly the first time! - toma
