        Presentation presentation = new Presentation();
        presentation.Slides.Clear();

        Slide slide = new Slide(SlideLayoutType.Blank);
        presentation.Slides.Add(slide);

        Shape shape1 = new Shape(ShapeType.Rectangle);
        shape1.Outline = new OutlineStyle { Fill = new SolidFill(Color.RoyalBlue), Width = 8 };
        shape1.Fill = new SolidFill(Color.White);
        shape1.X = 30;
        shape1.Y = 30;
        shape1.Width = 300;
        shape1.Height = 300;
        slide.Shapes.Add(shape1);

        ShapeEffectProperties e_properties = new ShapeEffectProperties();
        e_properties.FillOverlay = new FillOverlayEffect {
            BlendMode = BlendMode.Lighten,
            Fill = new SolidFill(Color.Yellow)
        };
        shape1.Effects = e_properties;
