PAL2RGB(1)                           General Commands Manual                           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 val-
              ues.

       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 sam-
              ples 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.
