NAME
       pal2rgb - convert a palette color TIFF image to a full color image

SYNOPSIS
       pal2rgb [ options ] input.tif output.tif

DESCRIPTION
       Pal2rgb converts a palette color TIFF image to a full color image by
       applying the colormap of the palette image to each sample to generate a
       full color RGB image.

OPTIONS
       Options that affect the interpretation of input data are:

       -C     This option overrides the default behavior of pal2rgb in
              determining whether or not colormap entries contain 16-bit or
              8-bit values.  By default the colormap is inspected and if no
              colormap entry greater than 255 is found, the colormap is
              assumed to have only 8-bit values; otherwise 16-bit values (as
              required by the TIFF specification) are assumed.  The -C option
              can be used to explicitly specify the number of bits for
              colormap entries: -C 8 for 8-bit values, -C 16 for 16-bit
              values.

       Options that affect the output file format are:

       -p     Explicitly select the planar configuration used in organizing
              data samples in the output image: -p contig for samples packed
              contiguously, and -p separate for samples stored separately.  By
              default samples are packed.

       -c     Use the specific compression algorithm to encoded image data in
              the output file: -c packbits for Macintosh Packbits, -c lzw for
              Lempel-Ziv & Welch, -c zip for Deflate, -c none for no
              compression.  If no compression-related option is specified, the
              input file's compression algorithm is used.

       -r     Explicitly specify the number of rows in each strip of the
              output file.  If the -r option is not specified, a number is
              selected such that each output strip has approximately 8
              kilobytes of data in it.

BUGS
       Only 8-bit images are handled.
