System.Windows.Shapes Classes

The System.Windows.Shapes namespace contains the basic drawing elements that make up most of the rendered content in the player. The Ellipse, Line, Path, Polygon, Polyline, and Rectangle classes render vector-based resolution-independent lines and shape, so they can be resized appropriately no matter what size the shape is being rendered in. In this appendix, we'll go into detail on the classes in this namespace and cover how you can use the classes.

The following classes are in the System.Windows.Shapes namespace:

• Shape

• Ellipse

• Line

• Path

• Polygon

• Polyline

• Rectangle

We'll cover each in the next sections.

Shape Class

The Shape class is the base class for the Ellipse, Line, Path, Polygon, Polyline, and Rectangle classes. The following sections describe the properties of the Shape class that are not inherited from UIElement or FrameworkElement.

Fill

Fill gets or sets the color (Brush object in System.Windows.Media) that specifies how to paint the interior of the shape. Figure D-1 demonstrates the full color table for the Brush object.

Figure D.1. Figure D-1

The Brush object can be one of the following five types:

• SolidColorBrush — Paints an area with a solid color.

• LinearGradientBrush — Paints an area with a linear gradient.

• RadialGradientBrush — Paints an area with a radial gradient.

• ImageBrush — Paints an area with an image.

• VideoBrush ...
