Usage

From source file:Diva.java

@Override

    // Paint the view.
    super.paint(g2, c);

    if (mActive) {
        // Create a radial gradient, transparent in the middle.
        java.awt.geom.Point2D center = new java.awt.geom.Point2D.Float(mX, mY);
        float radius = 72;
        float[] dist = { 0.0f, 1.0f };
        Color[] colors = { new Color(0.0f, 0.0f, 0.0f, 0.0f), Color.BLACK };
