[GRASSLIST:8478] Re: New GIS Manager version

[Michael Barton]

Ian,

Looking at your jpg, I think it is actually working OK. Have you tried doing
the same thing with d.his to compare?

I'm looking especially at the crater in the upper center of the aerial
photo. It has the grey shades of the aerial, but seems to have the relief of
the underlying map. The problem is that it is very difficult to see with
grey on grey. Try it with a color image draped on a relief map.

Michael
