Usage

From source file:TexturePaintFill.java

public void paint(Graphics g) {
    Graphics2D g2 = (Graphics2D) g;
    // a round rectangle.
    RoundRectangle2D r = new RoundRectangle2D.Float(25, 35, 150, 150, 25, 25);
    // a texture rectangle the same size as the texture image.
    Rectangle2D tr = new Rectangle2D.Double(0, 0, mImage.getWidth(), mImage.getHeight());
    // the TexturePaint.
    TexturePaint tp = new TexturePaint(mImage, tr);
    // Now fill the round rectangle.
    g2.setPaint(tp);
