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 image to a full color image by	apply-
       ing 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 numentries
	      This option overrides the	default	behavior of pal2rgb in	deter-
	      mining  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 planarconfig
	      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 compress
	      Use the specified	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 striprows
	      Explicitly  specify the number of	rows in	each strip of the out-
	      put file.	If the -r option is not	specified,  a  number  is  se-
	      lected such that each output strip has approximately 8 kilobytes
	      of data in it.

BUGS
       Only 8-bit images are handled.
