NAME
       tiff2bw - convert a color TIFF image to greyscale

SYNOPSIS
       tiff2bw [ options ] input.tif output.tif

DESCRIPTION
       Tiff2bw	converts  an  RGB  or  Palette color TIFF image to a greyscale
       image by combining percentages of the red, green,  and  blue  channels.
       By  default,  output samples are created by taking 28% of the red chan‐
       nel, 59% of the green channel, and 11% of the blue channel.   To	 alter
       these percentages, the -R, -G, and -B options may be used.

OPTIONS
       -c     Specify  a compression scheme to use when writing image data: -c
	      none for no compression, -c packbits for the  PackBits  compres‐
	      sion algorithm, -c zip for the Deflate compression algorithm, -c
	      g3 for the CCITT Group 3 compression algorithm, -c  g4  for  the
	      CCITT Group 4 compression algorithm, and -c lzw for Lempel-Ziv &
	      Welch (the default).

       -r     Write data with a specified number of rows per strip; by default
	      the  number  of  rows/strip  is  selected	 so that each strip is
	      approximately 8 kilobytes.

       -R     Specify the percentage of the red channel to use (default 28).

       -G     Specify the percentage of the green channel to use (default 59).

       -B     Specify the percentage of the blue channel to use (default 11).
