pgmtolispm(1) AMIGA (06 March 1990) pgmtolispm(1)
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.
SEE ALSO
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.
