Hi everybody:
I´m using VisAD to visualize radar and lightling data. Now I've inserted
also a GIF image on the background by visad.data.gif.GIFForm. The image
is apearing behind all the other data, as it shoud.
The problem is that I could not make the undefined radar data invisible
(alpha =0). I´m using a Integer2DSet and setting the points outside the
radar range to Float.NaN but these points apear on the display´s
background color.
I also tried to map to RGBA instead of RGB but didn´t worked either.
Thanks already Cicero A. W. Z.
