pgmtolispm(1)                                       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  unfortu-
       nate.

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  eas-
       ily be displayed on the screen).

       No color.
