getBounds2D


public Rectangle2D getBounds2D()
Returns a high precision and more accurate bounding box of the Shape than the getBounds method.

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. Returns the bounding box of this QuadCurve2D.

Specified by: Returns:
getBounds2D a Rectangle2D in interface Shape
that is the bounding box of the shape of this QuadCurve2D.
