Revision Log
Cleaned these scripts up a little. Instead of setting the PATH, it just uses the directory specified to call each utility with its full path. Also added some documentation and got rid of some cruft (which, of course, one can still pull out of CVS if needed). Incidentally, all the utilities used in these two scripts are from the netpbm package.
1 #!/bin/sh 2 3 # This script wraps system-dependant calls to several netpbm utilities. 4 # In order to use this script, set the NETPBM variable below to the 5 # directory which contains giftopnm, ppmtopgm, and pnmtops. 6 7 NETPBM=/usr/X11/bin 8 9 # If you wish to set the paths to each utility separately, i.e. if they 10 are in different locations, do so below: 11 12 GIFTOPNM=$NETPBM/giftopnm; 13 PPMTOPGM=$NETPBM/ppmtopgm; 14 PNMTOPS=$NETPBM/pnmtops; 15 16 # There should be no need for customization beyond this point. 17 18 umask 022 19 cat $1 | $GIFTOPNM | $PPMTOPGM | $PNMTOPS -noturn 2>/dev/null > $2 20 21 # CODER NOTE: 22 # We used to use `pnmdepth 1' instead of ppmtopgm as it creates a 23 # monochrome image (1 bit) rather than a greyscale image (8 bits). 24 # However, this was causing improper display of some sort in PDFs.
