ImageMapLayer RenderingRule

Display an Image Service from ArcGIS Online or ArcGIS Server and apply a rendering rule to dynamically modify the display of the raster dataset. Rendering rules are created using a pre-defined set of raster functions contained in the ArcGIS Server 10 REST API. This example shows a raster image generated from raw LIDAR (Light Detection and Ranging) data rendered with a hillshade. More information about Image Services can be found in the L.esri.Layers.ImageMapLayer documentation.
