pgmtolispm(1)pgmtolispm(1)NAMEpgmtolispm - convert a portable graymap into Lisp Machine
format
SYNOPSISpgmtolispm [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.
SEE ALSOlispmtopgm(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.
