解决方案
以下示例演示了如何使用 RenderingHints 类检查是否打开了抗锯齿。
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import javax.swing.JComponent;
import javax.swing.JFrame;
public class Main {
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.add(new MyComponent());
frame.setSize(300, 300);
frame.setVisible(true);
}
}
class MyComponent extends JComponent {
public void paint(Graphics g) {
Graphics2D g2 = (Graphics2D) g;
RenderingHints rh = g2.getRenderingHints();
boolean bl = rh.containsValue (RenderingHints.VALUE_ANTIALIAS_ON);
System.out.println(bl);
g2.setRenderingHint(
RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
}
}
