NAME

   lispmtopgm - convert a Lisp Machine bitmap file to PGM

SYNOPSIS

   lispmtopgm [lispmfile]

DESCRIPTION

   This program is part of Netpbm.

   listpmfile reads a Lisp Machine bitmap as input and produces a
PGM image as
   output.

   This is the file format written by the tv:write-bit-array-file
function on
   TI Explorer and Symbolics lisp machines.

   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
monochrome
   instead and produce PGM. This is unfortunate.

SEE ALSO

   pgmtolispm, pgm

LIMITATIONS

   The	Lispm bitmap file format is a bit quirky; Usually the im-
age in the file
   has its width rounded up to the next higher	multiple  of  32,
but not always.
   If  the  width  is not a multiple of 32, we don't deal with it
properly, but
   because of the Lispm microcode, such arrays are  probably  not
image data
   anyway.

   Also,  the Lispm code for saving bitmaps has a bug, in that if
you are
   writing a bitmap which is not mod32 across, the file may be up
to 7 bits too
   short!   They  round	 down  instead of up, and we don't handle
this bug
   gracefully.
