DESCRIPTION
Tiff2bw
converts a color
TIFF
image to a grayscale image by
combining percentages of the red, green, and blue channels.
By default, output samples are created by taking
28% of the red channel, 59% of the green channel, and 11% of
the blue channel.
To alter these percentages, the
-r,
-g,
and
-b
options may be used.
This program is a (trivial) ripoff of Paul Haeberli's
tobw
program.
BUGS
Only 8-bit RGB images are handled.
