## NAME

pgmtolispm - convert a PGM image to Lisp Machine format

## SYNOPSIS

pgmtolispm [pgmfile]

## DESCRIPTION

This program is part of Netpbm.

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.

## OPTIONS

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

## SEE ALSO

lispmtopgm, pgm

## LIMITATIONS

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 a multiple of 32 pixels wide cannot be passed to the Lispm BITBLT function, and thus cannot easily be displayed on the screen).

No color.
