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  behaviour	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 col-
	      ormap 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 compres-
	      sion.  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 out-
	      put  file.   If  the  -r	option	is not specified, a number is
	      selected such that each output strip has approximately 8	kilo-
	      bytes of data in it.

BUGS
       Only 8-bit images are handled.
