CreateKeyframe Method

C#
Visual Basic (Declaration)

public Keyframe CreateKeyframe( 
   Range range,
   TimeSpan atTime,
   AnimationTransition transition
)

Public Function CreateKeyframe( _
   ByVal range As Range, _
   ByVal atTime As TimeSpan, _
   ByVal transition As AnimationTransition _
) As Keyframe

Parameters

range: The value of the range.
atTime: The time at which to insert the keyframe in the track.
transition: The transition for min and max value of the range. In the UI the default is ArcGIS.Core.CIM.AnimationTransition.Linear.

If a keyframe already exists at that time it will be overwritten. The time is rounded to the nearest millisecond. When you create a keyframe the specified transition will be used for the min and max values of the range. It is possible to change the transitions for the min or max by settting the transition on the keyframe./>

Create a new range keyframe.

C#

public void CreateRangeKeyframe(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);
}

Target Platforms: Windows 10, Windows 8.1
