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

SYNOPSIS [-of format] [-b band] [-rgba] source_file dest_file


This utility will convert a pseudo-color band on the input file into an output RGB file of the desired format.
-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.
Generate a RGBA file (instead of a RGB file by default).
The input file.
The output RGB file that will be created.

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

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