Usage

From source file:Main.java

public void drawImage() {
    Graphics2D g = img.createGraphics();
    RenderingHints hints = new RenderingHints(RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);
    g.setRenderingHints(hints);//from  w  w w.ja v  a 2  s.  c om

    g.setColor(Color.RED);
    int x = (int) mouse.getX();
    int y = (int) mouse.getY();
    g.setStroke(new BasicStroke(2));
    int s = 3;
    g.drawLine(x - s, y, x + s, y);
    g.drawLine(x, y - s, x, y + s);
