Defines a predefined raster renderer associated with an ImageryLayer.presetRenderers or ImageryTileLayer.presetRenderers. A raster layer may contain a data source of multidimensional data with multiple variables. These different variables often require different types of default symbology, which can be preconfigured individually and saved with the layer. This means you don't have to redefine the symbology each time you select a different variable. The predefined raster renderers can also be used as a general list of renderers available for clients, without a variable or raster function templates.

Properties
method
- Type
- "raster-function-template" | "variable" | "none"
Specifies how to match the renderer. The matching method can be based on a variable, a raster function template, or no specific method. Example workflow in a client app: When changing a multidimensional variable, the client can find the corresponding preset renderer with the method "variable" and the value as the variable name, then set it on the layer.
- Default value
- "none"

Methods
fromJSON
- Signature
-
fromJSON (json: any): any
Creates a new instance of this class and initializes it with values from a JSON object
generated from an ArcGIS product. The object passed into the input json
parameter often comes from a response to a query operation in the REST API or a
toJSON()
method from another ArcGIS product. See the Using fromJSON()
topic in the Guide for details and examples of when and how to use this function.
Parameters
| Parameter | Type | Description | Required |
|---|---|---|---|
| json | A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects. | |
- Returns
- any
Returns a new instance of this class.
clone
- Signature
-
clone (): this
Creates a deep clone of this object. Any properties that store values by reference will be assigned copies of the referenced values on the cloned instance.
- Returns
- this
A deep clone of the class instance that invoked this method.
toJSON
- Signature
-
toJSON (): any
Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.
- Returns
- any
The ArcGIS portal JSON representation of an instance of this class.
