ArcGIS Runtime SDK for Java

Rgb Renderer

Demonstrates how to use a RGB renderer on a raster layer. An RGB renderer is used to adjust the color bands of a multispectral image.

How it works

To apply a RgbRenderer to a RasterLayer:

  1. Create a Raster from a multispectral raster file.
  2. Create a raster layer from the raster.
  3. Create a Raster from the raster layer and set it to the map.
  4. Create a rgb renderer, specifying the stretch parameters and other properties.
  5. Set the renderer on the raster layer with rasterLayer.setRenderer(renderer).
