<i>ras2tiff</i> converts a file in the Sun rasterfile format
to <small>TIFF.</small> By default, the <small>TIFF</small>
image is created with data samples packed
(<i>PlanarConfiguration</i>=1), compressed with the
Lempel-Ziv & Welch algorithm (<i>Compression</i>=5), and
with each strip no more than 8 kilobytes. These
characteristics can overriden, or explicitly specified with
the options described below.</td></table>

<tr valign="top" align="left">
<td width="10%"></td><td width="90%">
Any colormap information in the rasterfile is carried over
to the <small>TIFF</small> file by including a
<i>Colormap</i> tag in the output file. If the rasterfile
has a colormap, the <i>PhotometricInterpretation</i> tag is
set to 3 (palette); otherwise it is set to 2 (RGB) if the
depth is 24 or 1 (min-is-black) if the depth is not
24.</td></table>
