Class ColormapRenderer

java.lang.Object
com.esri.arcgisruntime.raster.RasterRenderer
com.esri.arcgisruntime.raster.ColormapRenderer
public final class ColormapRenderer extends RasterRenderer
A colormap renderer provides a discrete mapping of raster cell values to colors to help visualize the raster data in a RasterLayer.

All cells matching the specified value will be rendered using the mapped color. This is useful for thematic mapping tasks such as land classification when you want the values in the raster layer to be represented by a specified color. This concept of this class is similar to a UniqueValueRenderer, except that ColormapRenderer is specifically for rendering raster cell values.
