How can I extract color values from an EPS file?

Question

I\'m trying to find all fill and stroke values used in an EPS file. I can parse the file, I just can\'t figure out how color values are defined in the EPS postscript section

Answer 1

the size of the bit image should not really matter if all you do is get a histogram and throw it away:

 pstopnm -stdout file.ps | ppmhist

I assume everyone has netpbm...netpbm.sourceforge.net
