This can all be done without epstopdf with the option -dEPSCrop, I've  
just found out:

gs  -q -dNOPAUSE -dBATCH -dEPSCrop -sOutputFile='OutputFilename.pdf'  
'InputFilename.eps'


Is there a way to change the color space of the pdf to cmyk, rgb, or  
gray-scale?
-dProcessColorModel=... and -sProcessColorModel=... don't seem to work?

Is there a way to output cmyk png and jpeg files?

Any help appreciated.
