PCT2RGB(1)                           GDAL                           PCT2RGB(1)

NAME
       pct2rgb - Convert an 8bit paletted image to 24bit RGB.

SYNOPSIS

          pct2rgb [--help] [--help-general]
                     [-of format] [-b band] [-rgba] [-pct palette_file] <source_file> <dest_file>

DESCRIPTION
       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. If not specified, the format is
              guessed from the extension.  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.

RETURN STATUS CODE
       The program returns status code 0 in case of success, and non-zero in
       case of error (non-blocking errors emitted as warnings are considered
       as a successful execution).
