By kind of similar I meant that rgb2pct.py takes the source image and a ready made palette from a file and writes out a new image by applying that palette. I am not a programmer but I have seen that they can do even bigger miracles than to modify some python script to use a paletted image as source instead of RGB image. -Jukka- _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
