[Gvsig_english] Problem with nodata value in raster style

[Silvia Franceschi]

Dear all,
I have a raster covering a region of which only a small part has valid data
and the rest is all nodata value (-9999 in the asc format).
The visualization is a map with all black in the part where there are
nodata values and white where there are the valid values. This is because
the styling considers -9999 as a value and therefore the legend is created
from -9999 to 50 (which is the maximum value of my data).

My question is, is there a way to specify the nodata value in the styling
or somewhere? I tried to specify the minimum and maximum values in the
styling window but they work only with equidistance and in addition all the
values below the minimum are visualized with the same color as the
minimum...

I am now using the latest build of the 2.3 version (2423) on a windows 64
bits.

Thanks in advance!

Silvia
