r.composite doesn't do anything special with regard to the region or mask. A "sparse" map (with large null areas) should have some advantage over a dense map, as the colour lookup optimises the case where a cell's value matches the previous cell's value, and also checks for null before other values. -- Glynn Clements <[email protected]> _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
