TIFF2BW(1)

NAME
tiff2bw - convert a color TIFF image to grayscale

SYNOPSIS
tiff2bw [ -r red% ] [ -g green% ] [ -b blue% ] from-file to-file

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.
