82<p>This option overrides the default behavior of
83<i>pal2rgb</i> in determining whether or not colormap
84entries contain 16-bit or 8-bit values. By default the
85colormap is inspected and if no colormap entry greater than
86255 is found, the colormap is assumed to have only 8-bit
87values; 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
90number of bits for colormap entries: <b>&minus;C 8</b> for
918-bit values, <b>&minus;C 16</b> for 16-bit values.</p>
