The ArcSegment class is not easy to grasp. Despite the illustrations of the
documentation, it is often necessary to grope to get the desired result.
In WpfDemo, the example application of
my book about WPF (in french), I developed a WPF page that directly shows the effect of the various properties of this class.
Note : this module does not work in .NET 3.5 SP1 beta, which introduces a regression bug. Fixed for final .NET 3.5 SP1 release on September the 7th, 2008.
