pgmtolispm - convert a portable graymap into Lisp Machine
format
SYNOPSIS
pgmtolispm [pgmfile]
DESCRIPTION
Reads a portable graymap as input. Produces a Lisp
Machine bitmap as output.
This is the file format read by the tv:read-bit-array-file
function on TI Explorer and Symbolics lisp machines.
Given a pgm (instead of a pbm) a multi-plane image will be
output. This is probably not useful unless you have a
color lisp machine.
Multi-plane bitmaps on lisp machines are color; but the
lispm image file format does not include a color map, so
we must treat it as a graymap instead. This is unfortu
nate.

lispmtopgm(1), pgm(5)
BUGS
Output width is always rounded up to the nearest multiple
of 32; this might not always be what you want, but it
probably is (arrays which are not modulo 32 cannot be
passed to the Lispm BITBLT function, and thus cannot eas
ily be displayed on the screen).
No color.
