−−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.
