Hello everyone,

I would like to know if it's possible within GDAL to convert an RGB raster 
image with a small number of colors exactly to an indexed colortable image. 
This would imply to avoid dithering. 

The only function I found is GDALDitherRGB2PCT() which always does dithering.

Thank you, and best regards,
