Paths and Geometries

In the previous chapter you took a look at a number of classes that derive from Shape, including Rectangle, Ellipse, Polygon, and Polyline. However, there's one Shape-derived class that you haven't considered yet, and it's the most powerful by far. The Path class has the ability to encompass any simple shape, groups of shapes, and more complex ingredients such as curves.

The Path class includes a single property, named Data, that accepts a Geometry object that defines the shape (or shapes) the path includes. You can't create a Geometry object directly because it's an abstract class. Instead, you need to use one of the seven derived classes listed in Table 14-1.
