Remarks

The OuterShadowEffect class exposes properties that you can use to configure the outer shadow effect:

BlurRadius

Specifies the outer shadow’s blur radius.

Angle

Specifies the angle to offset the shadow.

Distance

Specifies how far to offset the shadow.

Color

Specifies the outer shadow color.

HorizontalScale | VerticalScale

Specifies the horizontal and vertical scale factors of the shadow.

HorizontalSkew | VerticalSkew

Specifies the horizontal and vertical skew angles of the shadow. This property is measured in degrees and can have values in the (-90, 90) range.

RotateWithShape

Specifies whether the shadow rotates with the shape.

The following code snippet applies an outer shadow effect to a shape:

namespace PresentationApiSample;

public class Program {
    public static void Main(string[] _) {

        Presentation presentation = new Presentation();

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

        Shape shape1 = new Shape(ShapeType.Rectangle);
        shape1.Outline = new LineStyle { Fill = new SolidFill(Color.RoyalBlue), Width = 8 };
        shape1.Fill = new SolidFill(Color.White);
        shape1.X = 1100;
        shape1.Y = 1100;
        shape1.Width = 300;
        shape1.Height = 300;
        slide.Shapes.Add(shape1);

        ShapeEffectProperties e_properties = new ShapeEffectProperties();

        e_properties.OuterShadow = new OuterShadowEffect {
            Angle = 135,
            BlurRadius = 50,
            Color = new OfficeColor(Color.Gray),
            Distance = 50,
            HorizontalScale = 100,
            VerticalScale = 100,
            HorizontalSkew = 0,
            VerticalSkew = 0,
            RotateWithShape = true
        };

        shape1.Effects = e_properties;
    }
