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