[Geoserver-devel] Geoserver ImageMosaicJDBC problem with interpolation setting

GeoServer GeoServer Developer

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
gdal_translate -of georaster...
co GENPYRAMID=BILINEAR ^
okay this one is for the pyramid generation

.) .xml file for ImageMosaicJDBC
scaleop interpolation="1"

.) 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 ImageMosaicJDBC 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?

Thanks for any clarification about that.

We tend to handle these requests on the user list (this list being for care and feeding of the geoserver code base). Your specific questions relate to the geotools library we use for data access and rendering; so you may wish to ask there.
