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.
