    • RectangularShape.getFrame()

  • getBounds2D

    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.

    Note that the definition of insideness can lead to situations where points on the defining outline of the shape may not be considered contained in the returned bounds object, but only in cases where those points are also not considered contained in the original shape.

    If a point is inside the shape according to the contains(point) method, then it must be inside the returned Rectangle2D bounds object according to the contains(point) method of the bounds. Specifically:

    shape.contains(p) requires bounds.contains(p)

    If a point is not inside the shape, then it might still be contained in the bounds object:

    bounds.contains(p) does not imply shape.contains(p)

    Specified by:

    getBounds2D in interface Shape

    Returns:

    an instance of Rectangle2D that is a high-precision bounding box of the Shape.
