[GRASSLIST:5826] alpha transparency

[Miroslav Sedivy]

Hello,

is there an alpha transparency support in grass5?
I have a raster map (grayscaled elevation map) and I would like to paint some vector areas on it (small regions filled-in with different plain colors: d.vect.area regionname fillcolor=xxx such as red, green, blue, ...). Now I would like to keep the elevation grayscale slightly visible beneath this colored areas, which means that I need to paint these small areas with some alpha transparency.

Thanks for your ideas,
   Miroslav
