getBounds2D

public Rectangle2D 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.

Specified by:

[getBounds2D](../../../java/awt/Shape.html#getBounds2D%28%29) in interface [Shape](../../../java/awt/Shape.html "interface in java.awt")

Overrides:

Parameters:

r - the Rectangle2D to be intersected with this Rectangle2D

Returns:

the largest Rectangle2D contained in both the specified Rectangle2D and in thisRectangle2D.

Since:

createUnion

public Rectangle2D createUnion(Rectangle2D r)

Returns a new Rectangle2D object representing the union of this Rectangle2D with the specifiedRectangle2D.

Specified by:

Parameters:

r - the Rectangle2D to be combined with this Rectangle2D

Returns:

the smallest Rectangle2D containing both the specified Rectangle2D and this Rectangle2D.

Since:

toString

public String toString()

Returns the String representation of thisRectangle2D.

Overrides:

[toString](../../../java/lang/Object.html#toString%28%29) in class [Object](../../../java/lang/Object.html "class in java.lang")
