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.
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)
