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

SYNOPSIS
     pal2rgb [options] input.tif output.tif

DESCRIPTION
     pal2rgb converts a palette color TIF 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
  Input Data Options
     The following input data options are supported:

     -C              Override the default behavior of pal2rgb  to
                     determine  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  color-
                     map  is  assumed  to have only 8-bit values.
                     Otherwise, 16-bit values, as required by the
                     TIF  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.



  Output File Options
     The following output file options are supported:

     -c              Specify a compression  scheme  to  use  when
                     writing image data:


                     -c lzw                  Lempel-Ziv and Welch
                                             algorithm.




                     -c none                 No compression.



                     -c packbits             PackBits compression
                                             algorithm.

                     -c zip                  Deflate  compression
                                             algorithm.


                     If no compression-related option  is  speci-
                     fied,  the  input-file compression algorithm
                     is used.


     -p              Explicitly select the  planar  configuration
                     used  to organize data samples in the output
                     image:


                     -p contig               Samples  are  packed
                                             contiguously.   This
                                             is the default.




                     -p separate             Samples  are  stored
                                             separately.



     -r              Write data with a specified number  of  rows
                     per  strip.  By  default, the number of rows
                     per strip is selected so that each strip  is
                     approximately 8 kilobytes.



OPERANDS
     The following operands are supported:

     input.tif       The name of the input TIF file.



     output.tif      The name of the output file.
