52 <p><i>ras2tiff</i> converts a file in the Sun rasterfile
53 format to <small>TIFF.</small> By default, the
54 <small>TIFF</small> image is created with data samples
55 packed (<i>PlanarConfiguration</i>=1), compressed with the
56 Lempel-Ziv &amp; Welch algorithm (<i>Compression</i>=5), and
57 with each strip no more than 8 kilobytes. These
58 characteristics can overridden, or explicitly specified with
59 the options described below.</p>
60 <!-- INDENTATION -->
61 <p>Any colormap information in the rasterfile is carried
62 over to the <small>TIFF</small> file by including a
63 <i>Colormap</i> tag in the output file. If the rasterfile
64 has a colormap, the <i>PhotometricInterpretation</i> tag is
65 set to 3 (palette); otherwise it is set to 2 (RGB) if the
66 depth is 24 or 1 (min-is-black) if the depth is not 24.</p>
