         tiff2bw - convert a color TIFF image to greyscale
         tiff2bw [ options ] input.tif output.tif
         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 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.
         -c   Specify a compression scheme to use when writing  image
              data:   -c none for no compression, -c packbits for the
              PackBits compression 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).
