SYNOPSIS
ppmtopi1 [file]
DESCRIPTION
ppmtopi1 reads a PPM image as input and produces an Atari Degas .pi1 file as output. PI1 is the low-resolution (320x200, 16 colors) format used by Degas on Atari ST computers. There are no command-line options beyond those common to all Netpbm programs. Input is read from the specified file or from standard input if no file is given. Output is written to standard output. Part of the Netpbm toolkit.
