  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>
