!!NAME


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
unfortunate.

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 easily be displayed
on the screen).


No color.
