Unfortunately this is not (yet?) possible. We are still missing discrete color ramps which would allow you to define custom colors, allow reversing of colors etc. Regards Martin ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Re: [Qgis-user] error with r.cost
Ambrish Dhaka, you need to check the region extent + resolution, probably you are exceeding the available RAM if you are having too many rows and columns. Get the information with: g.region -p or the respective menu entry.
