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.
