- 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 unfortunate.

- 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 easily be displayed
- on the screen).
-
- No color.
