ImageAngleParameters

Property Overview

Property Details

angleNames String[]

Angle names to be computed. By default both north and up angles are computed.

Possible values	Description
["up"]	Angle computed after rotating the map so that the top of the image is always oriented to the direction of sensor when it acquired the image.
["north"]	Angle computed after rotating the map so that the top of the image is always oriented toward north. This angle is essentially the arithmetic rotation from imageCoordinateSystem to pixel space.
["north", "up"]	Angle computed for all directions.

Default Value:["north","up"]

declaredClass Stringreadonly inherited

The name of the class. The declared class name is formatted as esri.folder.className.

point Pointautocast

A point geometry that defines the reference point of rotation to compute the angle direction. By default the centroid of the image is used.

rasterId Number

The rasterId of a raster catalog in the image service. The specified raster catalog's image coordinate system will be used in the calculation.

spatialReference SpatialReferenceautocast

The spatial reference used to compute the angles. If not specified, the image service's spatial reference will be used.

Method Overview

Method Details

fromJSON(json){*}static

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.

Parameter:

json Object 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:

Type	Description
*	Returns a new instance of this class.

own(handleOrHandles)inherited

Since: ArcGIS API for JavaScript 4.24

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.whenOnce(() => !view.updating)
  .then(() => {
    wkidSelect.disabled = false;
});

handle.remove();

// Assign a handle using own()
this.own(reactiveUtils.whenOnce(() => !view.updating)
  .then(() => {
    wkidSelect.disabled = false;
  }));

Parameter:

handleOrHandles WatchHandle|WatchHandle[] Handles marked for removal once the object is destroyed.

toJSON(){Object}

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.

Returns:

Type	Description
Object	The ArcGIS portal JSON representation of an instance of this class.
