Track Class—ArcGIS Pro

Track Class

In This Topic

Represents the base class for all track types.

Syntax

C#
Visual Basic (Declaration)

public abstract class Track

Public MustInherit Class Track

Remarks

A track stores the collection of keyframes whose values and transitions define the interpolated values for each frame of the animation. The Tracks property for the animation always returns 4 tracks: a CameraTrack, a LayerTrack, a TimeTrack and a RangeTrack. Each track type stores a corresponding keyframe for that type and is used to animate either the camera position, map time, map range, or layer visibility and transparency. The duration of the animation is equal to the time of the last keyframe in all tracks. The animation is removed from the map by deleting all keyframes in all tracks.

Example

Create Camera Keyframe

public void CreateCameraKeyframe(TimeSpan atTime)
{
  var mapView = MapView.Active;
  if (mapView != null)
    return;

  var animation = mapView.Map.Animation;
  var cameraTrack = animation.Tracks.OfType<CameraTrack>().First(); //There will always be only 1 CameraTrack in the animation.
  cameraTrack.CreateKeyframe(mapView.Camera, atTime, ArcGIS.Core.CIM.AnimationTransition.FixedArc);    
}
