    Rendering an image with a circle onto the background image and saving the result into a png file.
    using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
    {
        Color backColor = gdpictureImaging.ARGB(255, 0, 255, 0); // Green color
        Color circleColor = gdpictureImaging.ARGB(255, 255, 0, 0); // Red color
     
        // Create a background image.
        int backImage = gdpictureImaging.CreateNewGdPictureImage(320, 200, 32, backColor);
     
        // Create an image used for drawing, and draw a circle on it.
        int circleImage = gdpictureImaging.CreateNewGdPictureImage(80, 80, 32, gdpictureImaging.ARGB(0, 0, 0, 0));
        gdpictureImaging.DrawFilledCircle(circleImage, 40, 40, 60, circleColor, false);
     
        // Draw an image with a circle onto the background image.
