ImageryLayer - server side raster function

This sample sets a service defined raster function in a rendering rule on an ImageryLayer. The image service is an IKONOS-2 scene of Toronto. It has four bands: blue, green, red, and near-infrared (NIR).

The TorontoFalseColor raster function template in the sample uses the NIR, Red, and Green bands to composite a false color image. It applies an extract band function and a percent clip stretch, which displays rendered pixel values differently from the original pixel values.

A popupTemplate is configured to display this information when you click any pixel on the layer.
