Буфферизация изображения

[ALKOrobot]

Каким образом возможно рисовать изображение на виртуальном экране и выводить на экран монитора методом repaint()?

public class Form extends javax.swing.JFrame {

    Image img, pic,deadfire;
    int x[] = new int[6];

        pic = getToolkit().getImage("back.JPG");

repaint();
