pgmtolispm - convert a PGM image to Lisp Machine format
This program is part of Netpbm(1).
pgmtolispm reads a PGM image as input and 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), pgmtolispm outputs a multi-plane image.
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 unfortunate.
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 easily be displayed on the screen).
