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.
