PAL2RGB(1)                                                          PAL2RGB(1)



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  con-
              tig  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  Macin-
              tosh  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  speci-
              fied, a number is selected such that each output strip has approximately 8 kilobytes of data in it.

BUGS
       Only 8-bit images are handled.
