CreateKeyframe Method (TimeTrack)

In This Topic

Create a new keyframe.

Syntax

C#
Visual Basic (Declaration)

public Keyframe CreateKeyframe( 
   TimeRange time,
   TimeSpan atTime,
   AnimationTransition transition
)

Public Function CreateKeyframe( _
   ByVal time As TimeRange, _
   ByVal atTime As TimeSpan, _
   ByVal transition As AnimationTransition _
) As Keyframe

Parameters

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

Remarks

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 start and end time of the time range. It is possible to change the transitions for the start or end time by settting the transition on the keyframe./>

Example

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);
}
