Question

我试图找到代码的哪一部分，它会裁剪我的图片，所以如果我用res 1200x2000设置图片我会得到它的一部分，为什么会这样？

代码来自：http://zetcode.com/tutorials/javagamestutorial/puzzle/

以下是完整代码：

public class Puzzle extends JFrame implements ActionListener {

    private JPanel centerPanel;
    private JButton button;
    private JLabel label;
    private Image source;
    private Image image;
    int[][] pos;
    int width, height;

    public Puzzle() {

        pos = new int[][] {
                            {0, 1, 2}, 
                            {3, 4, 5}, 
                            {6, 7, 8}, 
                            {9, 10, 11}
                        };


        centerPanel = new JPanel();
        centerPanel.setLayout(new GridLayout(4, 4, 0, 0));

        ImageIcon sid = new ImageIcon(Puzzle.class.getResource("icesid.jpg"));
        source = sid.getImage();

        width = sid.getIconWidth();
        height = sid.getIconHeight();


        add(Box.createRigidArea(new Dimension(0, 5)), BorderLayout.NORTH);    
        add(centerPanel, BorderLayout.CENTER);

        for ( int i = 0; i < 4; i++) {

                    label = new JLabel("");
                    centerPanel.add(label);
                } else {
                    button = new JButton();
                    button.addActionListener(this);

                }
            }
        }

        setSize(325, 275);
        setTitle("Puzzle");
        setResizable(false);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

             centerPanel.add(label, labelIndex);
             centerPanel.add(button,labelIndex);
             centerPanel.validate();
        }
    }
}

Answer 1

image = createImage（new FilteredImageSource（source.getSource（）， new CropImageFilter（j width / 3，i height / 4，（宽度/ 3）+ 1，高度/ 4）））;

好吧我没注意它。这应该是你的问题，你总是把尺寸设置为325 * 275！ setSize（325,275）;
