Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    BufferedImage bi;
    bi = new BufferedImage(WIDTH, HEIGHT, BufferedImage.TYPE_INT_RGB);
    Graphics g = bi.getGraphics();
    for (int i = 0; i < NUM_ITER; i++) {
        g.setColor(Color.RED);/*  w w  w  . j ava 2  s . co  m*/
        g.drawLine(1, 2, i, i + 1);
    }
    g.dispose();
