description
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.
bugs
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.
