Interface Stroke
- All Known Implementing Classes:
BasicStroke
public interface Stroke
The Stroke
interface allows a Graphics2D
object to obtain a Shape
that is the decorated outline, or stylistic representation of the outline, of the specified Shape
. Stroking a Shape
is like tracing its outline with a marking pen of the appropriate size and shape. The area where the pen would place ink is the area enclosed by the outline Shape
.
The methods of the Graphics2D
interface that use the outline Shape
returned by a Stroke
object include draw
and any other methods that are implemented in terms of that method, such as drawLine
, drawRect
, drawRoundRect
, drawOval
, drawArc
, drawPolyline
, and drawPolygon
.
The objects of the classes implementing Stroke
must be read-only because Graphics2D
does not clone these objects either when they are set as an attribute with the setStroke
method or when the Graphics2D
object is itself cloned. If a Stroke
object is modified after it is set in the Graphics2D
context then the behavior of subsequent rendering would be undefined.

Method Detail
createStrokedShape
Shape createStrokedShape(Shape p)
Returns an outline Shape
which encloses the area that should be painted when the Shape
is stroked according to the rules defined by the object implementing the Stroke
interface.
- Parameters:
-
p
- aShape
to be stroked - Returns:
- the stroked outline
