The fpipe facility you were using writes the input to a file(whos location is set to $FILE in the filter)and then the command line would use that as its source. Then the magicfilter filter would then pass it back to the magicfilter filter(because it is defined as a pipe) until it matches a filter or ffilter facility. So you should do, # PostScript 0 %! fpipe gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- $FILE 0 \004%! fpipe gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- $FILE Or just use the pipe facility since gs doesn't need to seek the input # PostScript 0 %! pipe gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- - 0 \004%! pipe gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- - Then your ppm filter facilty will catch these as they are fed back into the filter as pbm 0 P4\n filter /usr/local/bin/pbm2ppa -s a4 - - I can't test this but it looks good to me. =) -- Brian --------------------------------------------------------------------- Mechanical Engineering [EMAIL PROTECTED] Purdue University http://www.ecn.purdue.edu/~servis ---------------------------------------------------------------------
