pdxperl has asked for the wisdom of the Perl Monks concerning the following question:

I'd like to be able to check PDF files for some common issues prior to them being printed. A perl solution would be nice but any CLI type of solution that runs under Linux would also be fine. Specifically, I need to know: 1) Are transparencies being used? 2) Are all fonts either embedded or outlined? 3) For embedded images: a) color space (CMYK, RGB ) b) DPI ( I realize this is probably requires a couple of steps, since it depends on the printed image size) Thanks
