The results from imageService.computeAngles() or ImageryLayer.computeAngles() method.
Property Overview
| Name | Type | Summary | Class |
|---|---|---|---|
The name of the class. | Accessor | ||
The computed north angle after rotating the map so the top of the image is oriented toward north. | ImageAngleResult | ||
The spatial reference used to compute the angles. | ImageAngleResult | ||
The computed up angle after rotating the map so the top of the image is always oriented to the direction of the sensor when it acquired the image. | ImageAngleResult |
Property Details
-
north
Propertynorth Number -
The computed north angle after rotating the map so the top of the image is oriented toward north. It is arithmetic rotation between image coordinate system and pixel space.
-
spatialReference
PropertyspatialReference SpatialReferenceautocast -
The spatial reference used to compute the angles.
-
up
Propertyup Number -
The computed up angle after rotating the map so the top of the image is always oriented to the direction of the sensor when it acquired the image. Top up works similarly to an in-car navigation system where the choices are often either north is at the top of the screen (therefore, not using a top up option) or the screen rotates so the travel direction is always displayed at the top.

Converts an instance of this class to its ArcGIS portal JSON representation. | ImageAngleResult |
Method Details
-
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.
-
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");
-
toJSON
MethodtoJSON(){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.
