getBounds2D
public Rectangle2D getBounds2D()
Returns a high precision and more accurate bounding box of theShape
than thegetBounds
method. Note that there is no guarantee that the returnedRectangle2D
is the smallest bounding box that encloses theShape
, only that theShape
lies entirely within the indicatedRectangle2D
. The bounding box returned by this method is usually tighter than that returned by thegetBounds
method and never fails due to overflow problems since the return value can be an instance of theRectangle2D
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 returnedbounds
object, but only in cases where those points are also not considered contained in the originalshape
.If a
point
is inside theshape
according to thecontains(point)
method, then it must be inside the returnedRectangle2D
bounds object according to thecontains(point)
method of thebounds
. Specifically:shape.contains(p)
requiresbounds.contains(p)
If a
point
is not inside theshape
, then it might still be contained in thebounds
object:bounds.contains(p)
does not implyshape.contains(p)
- Specified by:
getBounds2D
in interfaceShape
- Returns:
- an instance of
Rectangle2D
that is a high-precision bounding box of theShape
. - Since:
- 1.2
- See Also:
