Usage

From source file:Main.java

public void paint(Graphics g) {
    BufferedImage bim;/*from w  w w  . j  a  va2  s.c  o m*/

    TexturePaint tp;

    String mesg = "www.java2s.com";

    Font myFont = new Font("Lucida Regular", Font.BOLD, 72);

    Color[] colors = { Color.red, Color.blue, Color.yellow, };

    int width = 8, height = 8;
    bim = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
    Graphics2D g2 = bim.createGraphics();
    for (int i = 0; i < width; i++) {
        g2.setPaint(colors[(i / 2) % colors.length]);
        g2.drawLine(0, i, i, 0);
        g2.drawLine(width - i, height, width, height - i);
    }
    Rectangle r = new Rectangle(0, 0, bim.getWidth(), bim.getHeight());
