Hello,
using geoserver 2.10.0, 2.12.2 with the ImageMosaicJDBC plugin and set
interpolation method to bicubic in the ImageMosaicJDBC configFile the
background isn't clear (see screenshot bicubic.jpg ).
If I set the interpolation method to bilinear in the imageMosaicJDBC config
file, the background is fine (see screenshot bilinear.jpg ).
Our rasterdata are 4 band tiff files, store in a oracle database.
If this a problem of the bicubic interpolation or can we handle it with
configuration, or is it a bug in the ImageMosaicJDBC plugin?
Any Ideas?
best regards,
Sebastian
