I am running Geoserver 2.10.1 with Pyramid, Image Mosaic JDBC and WPS plugins installed. I have configured "Web Map Service" / "Raster Rendering Options" / "Default Interpolation" to "Bicubic". But when I view an image mosaicking raster layer with "Open Layers" and zoom into the map then a border surrounds the map at high zoom levels. The border width seems to be 1,5 pixel of raster data. I have attached 2 screenshots to explain: one with interpolation=1 and another with interpolation=3 at zoom level 1:4k. The effect begins to appear at zoom level 1:34k. At zoom level 1:1k the whole map is black. At zoom level 1:100 the map gets white. When I zoom in and out several times, then GeoServer hangs with high cpu load. |
