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.
