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); 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.
