Detailed Description

A rendering rule defines the processing that is to be done to the ArcGIS image service. An instance of this class can be created from a RenderingRuleInfo or a JSON string that specifies a service-defined or client-defined rendering rule. See {https://developers.arcgis.com/documentation/common-data-types/raster-function-objects.htm}{Raster function objects} for a list of functions and the syntax for rendering rules.

Create a RenderingRule:

// get the rendering rule info at the selected index
const renderingRuleInfo = imageServiceRaster.serviceInfo.renderingRuleInfos[index];
// create a rendering rule object using the rendering rule info
const renderingRule = ArcGISRuntimeEnvironment.createObject("RenderingRule", {renderingRuleInfo: renderingRuleInfo});
// create a new image service raster
const newImageServiceRaster = ArcGISRuntimeEnvironment.createObject("ImageServiceRaster", {url: imageServiceUrl});
// apply the rendering rule
newImageServiceRaster.renderingRule = renderingRule;
// create a raster layer using the image service raster
const rasterLayer = ArcGISRuntimeEnvironment.createObject("RasterLayer", {raster: newImageServiceRaster});

You can see the complete code in the QML sample Raster Rendering Rule.
