How can I use PDF 1.6 documents in Perl's CAM::PDF?

Answer 1

+6 A:

You can use Ghostscript to the job:

gs -dNOPAUSE -sDEVICE=pdfwrite -dCompatibilityLevel=1.3 -sOUTPUTFILE=out.pdf -dBATCH in.pdf

I finally tried this solution and with a 3,700 Kb %1.4 pdf doc, the converted version has 14,744 Kb! Am I doing something wrong? I used gswin32 8.70

In my experience the converted documents were bigger than than the originals but not as extremely as in your case (arround 150% to 200% of the original size). As I don't know the exact characteristics of your documents I can't judge on what the problem actually is but there must be something in your documents which can't be expressed efficiently in PDF 1.3 as I can't see any obvious mistake on your side.
