Returns a high precision and more accurate bounding box of the Shape than the getBounds method. Note that there is no guarantee that the returned
Rectangle2D
is the smallest bounding box that encloses the Shape, only that the Shape lies entirely within the indicated Rectangle2D. The bounding box returned by this method is usually tighter than that returned by the getBounds method and never fails due to overflow problems since the return value can be an instance of the Rectangle2D that uses double precision values to store the dimensions.
