PCT2RGB(1)                           GDAL                           PCT2RGB(1)

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

SYNOPSIS

          pct2rgb.py [--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.

       --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.

       NOTE: pct2rgb.py is a Python script, and will only work if GDAL was
       built with Python support.

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