Class HillshadeRenderer

java.lang.Object
com.esri.arcgisruntime.raster.RasterRenderer
com.esri.arcgisruntime.raster.HillshadeRenderer
Direct Known Subclasses:
BlendRenderer

public class HillshadeRenderer extends RasterRenderer
Renderer that uses a hillshade. A hillshade is a grayscale 3D representation of the surface, with the light's relative position taken into account for shading the image.

The altitude and azimuth properties specify the light's position.
