Zoom Gesture
Pinch to zoom in and zoom out on image or maps.
Multitouch.inputMode = MultitouchInputMode.GESTURE;
stage.addEventListener(TransformGestureEvent.GESTURE_ZOOM,zoomHandler);
private function zoomHandler(evt:TransformGestureEvent):void{
// previewImage is the container of image/map anything
previewImage.scaleX *= evt.scaleX;
previewImage.scaleY *= evt.scaleY;
}
Will be posting on more Gestures and Touch Events. Feel free for comments / suggestions
