You can set up an Auto-Follow camera to track a moving entity in the map. The auto-follow source can be either a Track, Draw object or a VideoMetadata source.
The API documentation can be found here
Each target item type has a corresponding AutoFollowSource, i.e TrackAutoFollowSource, DrawObjectAutoFollowSource and VideoMetadataAutoFollowSource. These are initialized with either an ItemId or a VideoMetadata object.
Example
The following example enables autofollow on different types of objects depending on what objects exists and are selected:
string videoName = "Video";
var video = _videoLayerViewModel.Videos.FirstOrDefault(metadata => metadata.Name == videoName);
if (video != null)
{
_autoFollow.TargetItem = new VideoMetadataAutoFollowSource { Video = video };
}
else if (_trackLayer.Selected.Count() > 0)
{
_autoFollow.TargetItem = new TrackAutoFollowSource { ItemId = _trackLayer.Selected.First() };
}
else if (_drawObjectLayer.SelectedDrawObjectIds.Count() > 0)
{
_autoFollow.TargetItem = new DrawObjectAutoFollowSource { ItemId = _drawObjectLayer.SelectedDrawObjectIds.First() };
}
