See the summary :-) Sample command line: ./bin/gs -sDEVICE=cups -dcupsColorSpace=0 -r300 -o test.cups ../fts_25_2523.pdf Cups output files written in cupsColorSpace=0 can be converted to ppmraw via a small program I wrote which I'll attach (it requires libcupsimage.a, so probably only runs on Linux).
Created attachment 7375 [details] readcups.c To compile use: cc -o readcups readcups.c -lcupsimage Requires the libcupsimage2-dev package (and probably libcups2-dev).
fixed with http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=b07cfe2e168d004ed1a4365e985d90c88fa61725
