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)
