NAME

       lispmtopgm - convert a Lisp Machine bitmap file to PGM

SYNOPSIS

       lispmtopgm [lispmfile]

DESCRIPTION

       This program is part of Netpbm(1).

       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.

OPTIONS

       There are no command line options defined specifically for lispmtopgm,  but  it  recognizes  the  options
       common to all programs based on libnetpbm (See  Common Options .)

SEE ALSO

       pgmtolispm(1), pgm(1)

LIMITATIONS

       The  Lispm bitmap file format is a bit quirky;  Usually the image 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.
