I have a problem with a blue-ish overlay color over my WMS layer that only is visible if there is part of the image background (nodata area) in the requested map extent.
The original image is a facsimile of an old map. It is georeferenced, resulting in approx. 45° rotation. Thus, the GeoTiff has large "no data" areas in the corners.
See original image, which is displayed correctly by geoserver's wms if there is no nodata visible in the requested extent:
...and if the nodata area on the bottom left is inside the viewport, it looks like this:
The SLD file used is
B0448_7c B0448_7c grid 1 1.0 2 1.0 3 1.0 If I set the layers InputTransparentColor to #000000 the wms will not show anything (only a white background in OpenLayers preview).
Unfortunately I cannot share the geotiff because it contains proprietary data.
How can I get rid of the blue?
