You can use levels=256 if you want 256 levels. But the resulting map will have a very large colour table (65536 rules), which will negatively affect the performance of anything which reads the colour table. Which is why the default is 32 levels rather than 256. -- Glynn Clements <gl...@gclements.plus.com> _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
