PAL2RGB(1)               USER COMMANDS                 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 behaviour 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 contig
          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 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.
