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. 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.
