Examples of java.awt.Stroke

java.awt.Stroke
The Stroke interface allows a {@link Graphics2D} object to obtain a {@link 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. @see BasicStroke @see Graphics2D#setStroke @version 1.23, 11/17/05
