Hi Andrea, I tried the preinstalled sf:sfdem layer which has a GeoTIFF resource and the WMS interpolation works fine. It seems to be a problem with the Image mosaicking/pyramidal jdbc plugin.
The bilinear interpolation doesn't work with pyramidal rasters either. There is nothing special in the logs. Any ideas? Do you need more info? I will try to describe a way to reproduce the problem starting with a plain server. Should I open a ticket for this?
