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  unfortu­
        nate.
 
SEE ALSO

 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.
