Java: Graphics2D
The javax.swing.Graphics2D class of Java 2 supports
many more graphics operations than the Graphics class.
For example,
Graphics2D additional features
- Aliasing
- Shapes
- Affine transformations (scaling, rotation, skewing)
-
[list many others, this is only a rough beginning]
Graphics objects are Graphics2D objects
The Graphics object that is passed to
paintComponent is really a Graphice2D
object in Java 2, so it may quickly be
downcast to Graphics2D
to make additional methods available.
For example
public void paintComponent(Graphics g) {
super.paintComponent(g);
Graphics2D g2 = (Graphics2D)g;
// Use g2 for all following operations
g2.drawLine(...);
