pgmtolispm(1)                        General Commands Manual                        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.
