|
|
* {@link Graphics2D} object to obtain a {@link Shape} that is the
|
|
* decorated outline, or stylistic representation of the outline,
|
|
* of the specified {@code Shape}.
|
|
* Stroking a {@code 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 {@code Shape}.
|
|
* <p>
|
|
* The methods of the {@code Graphics2D} interface that use the
|
|
* outline {@code Shape} returned by a {@code Stroke} object
|
|
* include {@code draw} and any other methods that are
|
|
* implemented in terms of that method, such as
|
|
* {@code drawLine}, {@code drawRect},
|
|
* {@code drawRoundRect}, {@code drawOval},
|
|
* {@code drawArc}, {@code drawPolyline},
|
|
* and {@code drawPolygon}.
|
|
* <p>
|
|
* The objects of the classes implementing {@code Stroke}
|
|
* must be read-only because {@code Graphics2D} does not
|
|
* clone these objects either when they are set as an attribute
|
|
* with the {@code setStroke} method or when the
|
|
* {@code Graphics2D} object is itself cloned.
|
|
* If a {@code Stroke} object is modified after it is set in
|
|
* the {@code Graphics2D} context then the behavior
|
|
* of subsequent rendering would be undefined.
