Animation Class—ArcGIS Pro

Animation Class

In This Topic

Represents the collection of tracks, keyframes and transitions that define an animation for the map.

Remarks

Animation is the process of creating a collection of sequential images and playing them back quickly to create an illusion of movement. Each image, just like a picture you take with a camera, marks a significant instance in time, and is called a keyframe. In ArcGIS Pro, animations are authored by defining a set of keyframes that the system uses to create interpolated intermediate frames. Animations can interpolate the camera position, map time, map range, and layer visibility and transparency.

An instance of this class is returned from the Map.Animation property and can be used to manipulate the state of the animation by creating, editing and deleting keyframes.

Example

Set Animation Length

{
  var animation = mapView.Map.Animation;
  var duration = animation.Duration;
  if (duration == TimeSpan.Zero)
    return;

  var factor = length.TotalSeconds / duration.TotalSeconds;
  animation.ScaleDuration(factor);
}

Scale Animation

{
  var animation = mapView.Map.Animation;
  var duration = animation.Duration;
  if (duration == TimeSpan.Zero || duration <= afterTime)
  {
    // Nothing to scale, leave
  }

  var factor = length.TotalSeconds / (duration.TotalSeconds - afterTime.TotalSeconds);
  animation.ScaleDuration(afterTime, duration, factor);
}

Camera Keyframes

{
  var animation = mapView.Map.Animation;
  var cameraTrack = animation.Tracks.OfType<CameraTrack>().First(); //There will always be only 1 CameraTrack in the animation.
  var result = cameraTrack.Keyframes.OfType<CameraKeyframe>().ToList();
  //Use the camera keyframes (if any)
}

Create Camera Keyframe

{
  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, AnimationTransition.FixedArc);
}

Create Time Keyframe

{
  var animation = mapView.Map.Animation;
  var timeTrack = animation.Tracks.OfType<TimeTrack>().First(); //There will always be only 1 TimeTrack in the animation.
  timeTrack.CreateKeyframe(mapView.Time, atTime, AnimationTransition.Linear);
}

Create Range Keyframe

{
  var animation = mapView.Map.Animation;
  var rangeTrack = animation.Tracks.OfType<RangeTrack>().First(); //There will always be only 1 RangeTrack in the animation.
  rangeTrack.CreateKeyframe(range, atTime, AnimationTransition.Linear);
}

Create Layer Keyframe

{
  var animation = mapView.Map.Animation;
  var layerTrack = animation.Tracks.OfType<LayerTrack>().First(); //There will always be only 1 LayerTrack in the animation.
  layerTrack.CreateKeyframe(layer, atTime, true, transparency, AnimationTransition.Linear);
}
