RenderingRule

The rule that specifies how images are rendered or processed on an ArcGIS image service. Raster images whose individual pixels represent elevation values can be rendered in a number of different ways, including representation of slope, aspect, hillshade, and shaded relief. A rendering rule defines how the ArcGIS image service renders its images.

You can create a RenderingRule from a RenderingRuleInfo or a JSON string that specifies a service-defined or client-defined rendering rule. For a list of functions and the syntax for these rendering rules, see https://developers.arcgis.com/documentation/common-data-types/raster-function-objects.htm.
