You can read a single band by using the band= parameter. If you want to generate a map whose categories represent a composite colour image, you can use r.composite, but this is usually a bad idea, as you're very limited in the kind of processing which you can perform on the result. Also, unless you accept a reduced colour depth, any process which requires the colours (e.g. display) will be slow. -- Glynn Clements <gl...@gclements.plus.com> _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
