Question

我尝试的代码是旋转图像但我想垂直旋转图像像旋转地球一样360度倾斜

我试过的代码是

 public class MainClass extends JPanel {
    static ImageIcon icon = null;
    static RotatedIcon rotate = null;
    static JLabel label = null;

    public MainClass() {
        try {
            BufferedImage wPic = ImageIO.read(this.getClass().getResource(
                    "globe.png"));
            icon = new ImageIcon(wPic);
            rotate = new RotatedIcon(icon, 180);

            label = new JLabel(rotate);

        } catch (Exception e) {
            System.out.println("raise exception");
        }
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        label.repaint();
    }

    public static void main(String[] args) throws IOException,
            InterruptedException {
        MainClass mainClass = new MainClass();
        JFrame frame = new JFrame();
        mainClass.add(label);
        frame.add(mainClass);
        frame.setSize(500, 500);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
        ActionListener taskPerformer = new ActionListener() {
            int degree = 360;

            public void actionPerformed(ActionEvent evt) {

                rotate.setDegrees(degree);
                degree = degree + 90;
                label.repaint();

                mainClass.repaint();

            }
        };
        Timer timer = new Timer(1000, taskPerformer);
        // timer.setRepeats(false);
        timer.start();
        Thread.sleep(5000);
    }
}

如果您只拥有世界的平面2D图像，那么您最好能够使用Marquee Panel。

Marquee Panel将允许您滚动图像，并且可以将其设置为在到达结尾时换行。你不会获得3D效果购买，你将用平面2D图像滚动世界。

如何沿y轴旋转图像？
