getBounds2D
public Rectangle2D getBounds2D()
Returns a high precision and more accurate bounding box of theShapethan thegetBoundsmethod. Note that there is no guarantee that the returnedRectangle2Dis the smallest bounding box that encloses theShape, only that theShapelies entirely within the indicatedRectangle2D. The bounding box returned by this method is usually tighter than that returned by thegetBoundsmethod and never fails due to overflow problems since the return value can be an instance of theRectangle2Dthat 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
shapemay not be considered contained in the returnedboundsobject, but only in cases where those points are also not considered contained in the originalshape.If a
pointis inside theshapeaccording to thecontains(point)method, then it must be inside the returnedRectangle2Dbounds object according to thecontains(point)method of thebounds. Specifically:shape.contains(p)requiresbounds.contains(p)If a
pointis not inside theshape, then it might still be contained in theboundsobject:bounds.contains(p)does not implyshape.contains(p)- Specified by:
getBounds2Din interfaceShape- Returns:
- an instance of
Rectangle2Dthat is a high-precision bounding box of theShape. - Since:
- 1.2
