AnimationTransition Enumeration
Specifies the method of transition for a value in a keyframe.
Syntax
Members
MemberDescription
AdjustableArc Value changes along a smooth curve to the end state. The tightness of the curve can be configured.
FixedArc Value changes along a tightly controlled curve to the end state.
Hold Value remains constant, equaling the previous keyframe's value.
Hop Value increases, using a parabolic curve, beyond the end state before returning back to it. The height of the curve can be configured.
Linear Value changes at a constant (linear) rate to the end state.
None The keyframe value is ignored.
Stepped Value switches to the end state at a specified point along the transition.
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);
}
Create Time Keyframe
public void CreateTimeKeyframe(TimeSpan atTime)
{
  var mapView = MapView.Active;
  if (mapView != null)
    return;

  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, ArcGIS.Core.CIM.AnimationTransition.Linear);
}
Create Range Keyframe
public void CreateRangeKeyframe(ArcGIS.Desktop.Mapping.Range range, TimeSpan atTime)
{
  var mapView = MapView.Active;
  if (mapView != null)
    return;

  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, ArcGIS.Core.CIM.AnimationTransition.Linear);
}
Create Layer Keyframe
public void CreateLayerKeyframe(Layer layer, double transparency, TimeSpan atTime)
{
  var mapView = MapView.Active;
  if (mapView != null)
    return;

  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, ArcGIS.Core.CIM.AnimationTransition.Linear);
