<p>This option overrides the default behavior of

entries contain 16-bit or 8-bit values. By default the

colormap is inspected and if no colormap entry greater than

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

8-bit values, <b>−C 16</b> for 16-bit values.</p>
