RAS2TIFF(1)                                                        RAS2TIFF(1)



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); other-
       wise 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.
