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 (PlanarCon-
       figuration=1), compressed with the Lempel-Ziv & Welch algorithm (Compression=5), and with each strip no more than 8 kilobytes.  These char-
       acteristics 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 raster-
       file 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 approxi-
	      mately 8 kilobytes.

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