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 samples packed (PlanarConfiguration=1),  compressed  with  the  Lempel-Ziv  &  Welch  algorithm
       (Compression=5),  and with each strip no more than 8 kilobytes.  These characteristics can overridden, 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 PhotometricInterpretation 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 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 kilobytes.

BUGS

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