floating point grass rasters and mapserver

[Andrea Antonello]

Hi folks,
I trying to visualize grass rasters with mapserver.

What I get are nice maps, but those that are floating point and numbers > 255 
are visualized in one single color, usually yellow, which probably only means 
that the image is rendered at low resolution level.

I read the documentation about rasters more than once, but I seem to miss a 
point. 

I use png24.

If I normalize the map (i.e. map*maxvalue/255), it shows up correctly, but I 
don't want to double the maps and also I want to see changes on the grass 
location.

Any hint is appreciated.

Best regards,
Andrea
