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 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 numentries
              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 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  compression.   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 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.
