  82 <p>This option overrides the default behavior of
  83 <i>pal2rgb</i> in determining whether or not colormap
  84 entries contain 16-bit or 8-bit values. By default the
  85 colormap is inspected and if no colormap entry greater than
  86 255 is found, the colormap is assumed to have only 8-bit
  87 values; otherwise 16-bit values (as required by the
  88 <small>TIFF</small> specification) are assumed. The
  89 <b>&minus;C</b> option can be used to explicitly specify the
  90 number of bits for colormap entries: <b>&minus;C 8</b> for
  91 8-bit values, <b>&minus;C 16</b> for 16-bit values.</p>
