16 This program is part of Netpbm(1).
17
18 pgmtolispm reads a PGM image as input and produces a Lisp Machine bit‐
19 map as output.
20
21 This is the file format read by the tv:read-bit-array-file function on
22 TI Explorer and Symbolics lisp machines.
23
24 Given a PGM (instead of a PBM), pgmtolispm outputs a multi-plane image.
25 This is probably not useful unless you have a color lisp machine.
26
27 Multi-plane bitmaps on lisp machines are color; but the lispm image
28 file format does not include a color map, so we must treat it as a
29 graymap instead. This is unfortunate.

33 There are no command line options defined specifically for pgmtolispm,
34 but it recognizes the options common to all programs based on libnetpbm
35 (See
36 Common Options ⟨index.html#commonoptions⟩ .)

44 Output width is always rounded up to the nearest multiple of 32; this
45 might not always be what you want, but it probably is (arrays which are
46 not modulo 32 cannot be passed to the Lispm BITBLT function, and thus
47 cannot easily be displayed on the screen).

49 No color.
