  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 
& 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> 
  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.
