Maybe QGIS detects the background color black as to be transparent?
In the Geoserver ImageMosaic plugin you can map an inputcolor to be
transparent.
But this is not possible in the Geoserver ECW plugin.
What do you use instead of ECW for rasters that is not too big, time and
memory consuming?
Thanks,
Ron
