    NAME
         ras2tiff - create a TIFF file from a Sun rasterfile
    
    SYNOPSIS
         ras2tiff [ options ] input.ras output.tif
    
    DESCRIPTION
         ras2tiff converts a file in the  Sun  rasterfile  format  to
         TIFF.  By  default, the TIFF image is created with data sam-
         ples packed  (PlanarConfiguration=1),  compressed  with  the
         Lempel-Ziv  & Welch algorithm (Compression=5), and with each
         strip no more than 8 kilobytes.  These  characteristics  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  PhotometricIn-
         terpretation  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.
    
    OPTIONS
         -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  base-
              line 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 kilobytes.
    
    BUGS
         Does not handle all possible  rasterfiles.   In  particular,
         ras2tiff does not handle run-length encoded images.
