Fundamentally, a Path is a Shape. But the Path can be used to create much more complex two-dimensional graphics than the other Shapes are capable of. The Path object can draw closed or open shapes, lines, and curves. For a description of the shapes that the Path element supports, see the Data property.
A Path supports two parallel techniques for declaring its contents: as an object model using discrete geometries declared in markup or code, or as a mini-language declared in markup. The geometry object model can use the GeometryGroup as data in order to specify a composite of multiple geometries. For details, see Geometries. The mini-language is analogous to a pathing language output used in some graphics tools. For more information on using the mini-language definition format for Path in markup, see Path Markup Syntax.

Performance Note: For best performance, avoid explicitly setting the Width and Height of a Path. Setting the Width and Height results in additional stretching, which has a performance cost. Instead, rely on the explicitly set coordinates of the Path and its contained data to control its shape and position. In effect, the Path will have a natural height/width, although those values are not reported to the object model. For more information, see Stretch. |
