Properties

Property Details
rotation The rotation of due north in relation to the top of the view in degrees. Default is 0.
scale The scale of the viewpoint. If scale is not defined, it will be automatically calculated such that it is just small enough to fit the entire targetGeometry within the view.
targetGeometry [Required] The target extent framed by the viewpoint.
