java swing background image

Question

I am using JFrame and I have kept a background image on my frame. Now the problem is that the size of image is smaller then the size of the frame so i have to keep the same

Answer 1

Another way to tile an image is with TexturePaint:

public class TexturePanel extends JPanel {

    private TexturePaint paint;

    public TexturePanel(BufferedImage bi) {
        super();
        this.paint = new TexturePaint(bi, new Rectangle(0, 0, bi.getWidth(), bi.getHeight()));
    }

    @Override
    protected void paintComponent(Graphics g) {
        Graphics2D g2 = (Graphics2D) g;
        g2.setPaint(paint);
        g2.fill(new Rectangle(0, 0, getWidth(), getHeight()));
    }
}
