示例1: StartZoom
protected override void StartZoom(SkeletonPoint rightHandPoint, SkeletonPoint leftHandPoint)
{
IsZooming = true;
_startMapResolution = _map.Resolution;
_startRightHandCoordinate = rightHandPoint.ToEsriWebMercatorMapPoint(_map);
_startLeftHandCoordinate = leftHandPoint.ToEsriWebMercatorMapPoint(_map);
_startDistance = _startRightHandCoordinate.DistanceFrom(_startLeftHandCoordinate);
if (KinectZoomStarted!= null)
{
KinectZoomStarted();
}
}示例2: DoZoomMap
private void DoZoomMap(MapPoint rightHandCoordinate, MapPoint leftHandCoordinate)
{
var centerX = (rightHandCoordinate.X + leftHandCoordinate.X) / 2;
var centerY = (rightHandCoordinate.Y + leftHandCoordinate.Y) / 2;
var zoomCenter = new MapPoint(centerX, centerY, _map.SpatialReference);
var currentDistance = rightHandCoordinate.DistanceFrom(leftHandCoordinate);
var zoomFactor = (currentDistance / _startDistance);
var targetResolution = _startMapResolution / Math.Pow(zoomFactor, 2);
_map.ZoomToResolution(targetResolution, zoomCenter);
