I use the ImageMosaicJDBC plugin to connect to an Oracle raster table. Maybe someone can clarify some things about the interpolation settings. There are multiple location where I can define the interpolation which is confusing to me:
gdal_translate -of georaster...
co GENPYRAMID=BILINEAR ^
- .xml file for ImageMosaicJDBC
- GeoServer Layer setting
Default interpolation setting=xx
The problem I have: I get a black/grey scaled border around my raster layer when I open it via WMS and I used the setting scaleop interpolation="2" or "3" in my xml.
Btw. I don't understand how that .xml file of ImageMosaicJDBC works. Is it only accessed once when I create a new data store? Or is it accessed every time the layer is accessed?
