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.
