AGSColormapRenderer Class Reference

Description

A colormap raster renderer.

Instances of this class represent a color map renderer that can help visualize raster data using AGSRasterLayer. It displays each pixel value in the raster using a color from the color map. Color maps contain a set of values that are associated with colors and are used to display a single-band raster consistently with the same colors. Each pixel value is associated with a color. You can use a color map to represent analyzed data, such as a classified image, or when displaying a topographic map (or index color-scanned image).
