[GIS] QGIS Export Color mapped GeoTIFF to GeoTiFF

Question

I've loaded a GeoTiff in QGIS (Single Band), and applied a Color Mapping. I can view it in the map canvas, but I would like to export the entire mapped GeoTiff as an appropriate 3 Band GeoTiff (i.e to R,G,B values 0-255).

I know that you can export the current view — but this is too low-resolution, and I would like to retain the current resolution.

Is there a hook in the Python QGIS module that might enable?

Answer 1

Raster -> Conversion -> PCT to RGB.

Alternatively, right-click on the colour rendered image and go "Save As". Tick the "Rendered image" radio button.
