       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.

       lispmtopgm(1), pgm(1)

       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.
