       pgmtolispm - convert a PGM image to Lisp Machine format





       This program is part of Netpbm(1).

       pgmtolispm  reads  a  PGM  image  as  input and 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), pgmtolispm outputs a multi-plane image.
       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(1)


       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.
