Java Matriz em um AWT帆布

我正在用SWING做一个战舰游戏。程序读取包含以下数据的文件：高度、长度、由船只数量填充的位置矩阵。问题是鼠标捕捉到的矩阵与文件中的矩阵相反，我不知道该怎么办。我将感谢任何帮助

代码如下：

框架：

import Model.ArcMap;
import java.awt.BorderLayout;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.JFrame;

public class GameFrame extends JFrame {

    private GameCanvas canvas;
    // CanvasThread updateScreenThread = new CanvasThread(canvas);
    private ArcMap archive;
    private int width;
    private int hight;
    public static final int AREA = 60;

    public GameFrame(ArcMap archve) {
        this.archive = archve;
        this.width = archve.getArcWidth();
        this.hight = archive.getArcHeight();

        canvas = new GameCanvas(archive);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        setLayout(new BorderLayout());
        setTitle("Stellar Battle");
        add(BorderLayout.CENTER, canvas);
        setResizable(false);

        // Define largura e altura da janela principal
        setSize(AREA * width, canvas.AREA * hight);
        setLocationRelativeTo(null);

        // setVisible(true);

        // Inicia Thread com timer para redesenhar a tela.
        // updateScreenThread.start();

        canvas.addMouseListener(new MouseListener() {

            @Override
            public void mouseReleased(MouseEvent e) {
                int x = e.getX();
                int y = e.getY();

                int x_pos = x / canvas.AREA;
                int y_pos = y / canvas.AREA;

                System.out.println(canvas.getShot(x_pos, y_pos);

            }

            @Override
            public void mouseClicked(MouseEvent e) {
            }

            @Override
            public void mousePressed(MouseEvent e) {
            }

            @Override
            public void mouseEntered(MouseEvent e) {
            }

            @Override
            public void mouseExited(MouseEvent e) {
            }

        });
    }
}

English请。不要覆盖绘制，覆盖绘制组件并确保绘制链保持接触，不要在绘制中加载图像什么是
