A polygon is a set of points that are connected by straight line segments and closed automatically. Polygons derive from polylines. You should not specify the same starting and ending points to close the polygon. Polygons are closed line segments for drawing filled shapes. The polygons uses the fill algorithm described under the heading "Fill algorithm for loops and polygons" on page 76 for filling the polygon. See Chapter 2 for an example polygon instantiation.
