Flattening Paths

A GraphicsPath object stores a sequence of lines and Bézier splines. You can add several types of curves (ellipses, arcs, cardinal splines) to a path, but each curve is converted to a Bézier spline before it is stored in the path. Flattening a path consists of converting each Bézier spline in the path to a sequence of straight lines.

To flatten a path, call the Flatten method of a GraphicsPath object. The Flatten method receives a flatness argument that specifies the maximum distance between the flattened path and the original path. The following illustration shows a path before and after flattening.
