Heading Property (Camera)

In This Topic

Gets or sets the Heading of the Camera, in degrees from North. 0 is North, 90 is West, 180 is South, -90 is East, etc. This property applies to both 2D and 3D views.

Syntax

C#
Visual Basic (Declaration)

public double Heading {get; set;}

Public Property Heading As Double

Remarks

Heading, Pitch and Roll are used to describe the viewing direction in a 3D view. Sometimes referred to as Yaw, Heading defines the angle of the camera rotating around the Z-axis. Imagine yourself as the camera. In this case adjusting the heading would be equivalent to looking to the left or right. The valid range for heading is -180 to 180 which are equal looking south. A value of 0 is looking north.

Heading is the one viewing direction property that is also used in 2D view. In a 2D view Heading determines and will determine the rotation of the view.

Example

Rotate the map view

public Task<bool> RotateView(double heading)
{
  //Get the active map view.
  var mapView = MapView.Active;
  if (mapView == null)
    return Task.FromResult(false);

  //Get the camera for the view, adjust the heading and zoom to the new camera position.
  var camera = mapView.Camera;
  camera.Heading = heading;
  return mapView.ZoomToAsync(camera, TimeSpan.Zero);
}

// or use the synchronous method
public Task<bool> RotateViewAsync(double heading)
{
  return QueuedTask.Run(() =>
  {
    //Get the active map view.
    var mapView = MapView.Active;
    if (mapView == null)
      return false;

    //Get the camera for the view, adjust the heading and zoom to the new camera position.
    var camera = mapView.Camera;
    camera.Heading = heading;
    return mapView.ZoomTo(camera, TimeSpan.Zero);
  });
}
