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 (Com-
    pression=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 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 compres-
    sion algorithm, -c jpeg for the baseline JPEG compression  algo-
    rithm, -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.
