This program is part of Netpbm.
hipstopgm reads a HIPS file as input and produces a PGM image as output.
If the HIPS file contains more than one frame in sequence, hipstopgm will concatenate all the frames vertically.
HIPS is a format developed at the Human Information Processing Laboratory, NYU.
There are no command line options defined specifically for hipstopgm, but it recognizes the options common to all programs based on libnetpbm (See Common Options.)
