       ras2tiff - create a TIFF file from a Sun rasterfile

       ras2tiff [ options ] input.ras output.tif

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

       Any colormap information in the rasterfile is carried over
       to the TIFF file by including a Colormap tag in the output
       file.   If  the  rasterfile  has  a  colormap,  the Photo-
       metricInterpretation 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.

       -c     Specify a compression scheme to  use  when  writing
              image data: -c none for no compression, -c packbits
              for the PackBits compression algorithm, -c jpeg for
              the baseline JPEG compression algorithm, -c zip for
              the Deflate compression algorithm, and -c  lzw  for
              Lempel-Ziv & Welch (the default).

       -r     Write  data  with  a  specified  number of rows per
              strip; by  default  the  number  of  rows/strip  is
              selected  so  that  each  strip  is approximately 8

       Does not handle all possible rasterfiles.  In  particular,
       ras2tiff does not handle run-length encoded images.
