       This  utility  will  convert a pseudo-color band on the input file into an output RGB file of the desired
       format.

       NOTE:
          pct2rgb is a Python utility, and is only available if GDAL Python bindings are available.

       --help Show this help message and exit

       --help-general
              Gives a brief usage message for the generic GDAL commandline options and exit.

       -of<format>
              Select the output format. Starting with GDAL 2.3, if not specified, the format is guessed from the
              extension (previously was GTiff). Use the short format name.

       -b<band>
              Band to convert to RGB, defaults to 1.

       -rgba  Generate a RGBA file (instead of a RGB file by default).

       -pct<palette_file>
              Extract the color table from <palette_file> instead of getting it from <source_file>.  Can be used
              to have a consistent color table for multiple files.  The <palette_file> must be either  a  raster
              file  in  a  GDAL supported format with a palette or a color file in a supported format (txt, qml,
              qlr).

       <source_file>
              The input file.

       <dest_file>
              The output RGB file that will be created.

       The '-expand rgb|rgba' option of gdal_translate obsoletes that utility.
