-==== GetBoundingBox() ==== +
-This method gets a bounding box of the Overlay. +
-=== Remarks === +
-This method is the concrete wrapper for the abstract method GetBoundingBoxCore. This method returns the bounding box of the Overlay.As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework. +

On another hand, when click to change the style of the overlay, we need to redraw the tile images to change the appearance. So we need refresh mode.
