+

+ This example manipulates data in a OpenLayers.Raster.Composite + using a series of OpenLayers.Raster.Operation methods. + RGB data from the WMS layer is translated to HSL, modified using + user supplied values, and translated back to RGB. The resulting + composite is displayed on the map with a OpenLayers.Layer.Raster. +
