This object contains helper methods for generating a RasterColormapRenderer for raster layers (i.e. ImageryLayer, ImageryTileLayer).
The createRenderer method in this module generates a renderer that may be applied directly to the input layer.
Method Overview

Generates a RasterColormapRenderer used to render imagery data.
ParametersSpecificationparams ObjectInput parameters for generating a colormap visualization. See the table below for details of each parameter.
Specificationlayer ImageryLayer|ImageryTileLayerThe input layer for which the renderer is generated.
renderingRule RasterFunctionoptionalDeprecated since 4.27. Use
rasterFunctioninstead.rasterFunction RasterFunctionoptionalSpecifies the function for how the requested image should be processed. When
rasterFunctionis applied, the server returns updated service information that reflects custom processing as defined by the raster function. If not provided, the output renderer is created using the layer'srasterFunction.signal AbortSignal|null|undefinedoptionalAllows for cancelable requests. If canceled, the promise will be rejected with an error named
AbortError. See also AbortController.ReturnsType Description Promise<RasterColormapResult> Resolves to an object containing a RasterColormapRenderer that can be set on the input layer.
