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.
