esri/renderers/support/RasterPresetRenderer
Defines a predefined raster renderer associated with an ImageryLayer or ImageryTileLayer. 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.

---|---|---|---|
The band ids associated with the raster renderer. | RasterPresetRenderer | ||
The name of the class. | Accessor | ||

The name of the preset renderer. | RasterPresetRenderer | ||
The raster renderer associated with the selected value and method. | RasterPresetRenderer | ||
The corresponding value of selected method. | RasterPresetRenderer |
Property Details
-
method
method String
-
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.

Method Details
-
Inherited from Accessor
-
Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.
// Manually manage handles const handle = reactiveUtils.when( () => !view.updating, () => { wkidSelect.disabled = false; }, { once: true } ); this.addHandles(handle); // Destroy the object this.destroy();
ParametershandleOrHandles WatchHandle|WatchHandle[]Handles marked for removal once the object is destroyed.
groupKey *optionalKey identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.
-
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.
ReturnsType Description this A deep clone of the class instance that invoked this method.
-
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.Parameterjson ObjectA 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.
ReturnsType Description * Returns a new instance of this class.

hasHandles
InheritedMethodhasHandles(groupKey){Boolean}
Inherited from Accessor -
Returns true if a named group of handles exist.
ParametergroupKey *optionalA group key.
ReturnsType Description Boolean Returns true
if a named group of handles exist.Example// Remove a named group of handles if they exist. if (obj.hasHandles("watch-view-updates")) { obj.removeHandles("watch-view-updates"); }
-
Inherited from Accessor
-
Removes a group of handles owned by the object.
ParametergroupKey *optionalA group key or an array or collection of group keys to remove.
Exampleobj.removeHandles(); // removes handles from default group obj.removeHandles("handle-group"); obj.removeHandles("other-handle-group");
-
toJSON
toJSON(){Object}
-
Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.
ReturnsType Description Object The ArcGIS portal JSON representation of an instance of this class.
