Hi, Try gdal_translate. Write your paletted image into .vrt file, open and edit the palette with text editor and convert the modified .vrt file into a new geotiff. rgb2pct.py utility http://www.gdal.org/rgb2pct.html is doing kind of similar thing with the -pct option. -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
