Hi
I try to apply some contrast enhancement to a geotiff file but I get some
null pointer exceptions. This happens with GeoServer 2.24.2 and 2.25.0. Any
idea what goes wrong? Perhaps not a supported compression or something
similar? The sld works without the ContrastEnhancement section or without
the ColorMap. Thanks.
