Here again.

Unfortunately I did not solve the problem but still having problem with
visualization under mapserver using GTiff files from r.out.gdal

I used a 8-bit GTiff form ArcGis and everything was quite fine, so I tried
to obtain better results with r.out.gdal using type=Byte but in the
resulting GTiff I see only a restricted range of colors correctly displayed.


More precisely, only green pixels seems to honour the raster's scale,
everything else is brown... even the sea.
So I wonder how you can obtain a useful GTiff from a GRASS raster for
visualization under mapserver

Apologize for being so annoying but didn't found useful resources on the
web, except for an "rgb2pct.py" script from http://gdal.maptools.org which
in turns requires gdal be compiled with python support. That may help
(unsure) but I hope something else could do the same without recompile.
