pct2rgb

Convert an 8bit paletted image to 24bit RGB.

Synopsis

pct2rgb.py [-of format] [-b band] [-rgba] 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.

-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).

<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.
