<p><i>Tiff2bw</i> converts an <small>RGB</small> or Palette
color <small>TIFF</small> 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 <b>&minus;R</b>,
<b>&minus;G</b>, and <b>&minus;B</b> options may be
used.</p>
