esri/webscene/background/ColorBackground
This type of Background allows to set a Color
as the background of a SceneView.
The view environment stars and atmosphere will show on top of the background when enabled.
To have a clear background color only, make sure to set both the view.environment.starsEnabled
and view.environment.atmosphereEnabled properties to false.
The default for ColorBackground is a fully opaque, black color. The example below shows how to change this:
const view = new SceneView({
container: "view",
map: map,
environment: {
background: {
type: "color",
color: [255, 252, 244, 1]
},
starsEnabled: false,
atmosphereEnabled: false
}
});
Set alphaCompositingEnabled to true when you want to make
the SceneView background partially or fully transparent and blend with the rest of the webpage.
const view = new SceneView({
container: "view",
map: map,
alphaCompositingEnabled: true,
environment: {
background: {
type: "color",
color: [255, 252, 244, 0.4]
},
starsEnabled: false,
atmosphereEnabled: false
}
});

Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.25Accessor since 4.0, addHandles added at 4.25. -
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.
-
clone
Methodclone(){ColorBackground} -
Creates a deep clone of the object.
ReturnsType Description ColorBackground A deep clone of the object 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
jsonparameter 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 AccessorSince: ArcGIS Maps SDK for JavaScript 4.25Accessor since 4.0, hasHandles added at 4.25. -
Returns true if a named group of handles exist.
ParametergroupKey *optionalA group key.
ReturnsType Description Boolean Returns trueif 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
Since: ArcGIS Maps SDK for JavaScript 4.25Accessor since 4.0, removeHandles added at 4.25. -
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");
