Hi, I have a clearly response from the log.
The nodata is unsupported for this kind of rasters. > LoadGDALImage(rt_sat.LC8191.rt.attuale): NODATA value -9999 in GDAL >file or PROCESSING directive largely ignored. Not yet fully supported for >unclassified scaled data. The NODATA value is excluded from auto-scaling >min/max computation, but will not be transparent. So I must found another solution for my rasters.
