EndType

Delphi type TEndType = (etPolygon, etJoined, etButt, etSquare, etRound);

C++ enum EndType {Polygon, Joined, Butt, Square, Round};

C# public enum EndType {Polygon, Joined, Butt, Square, Round};

The EndType enumerator is only needed when offsetting (inflating/shrinking). It isn't needed for polygon clipping.

EndType has 5 values:

Polygon: the path is treated as a polygon
Joined: ends are joined and the path treated as a polyline
Square: ends extend the offset amount while being squared off
Round: ends extend the offset amount while being rounded off
Butt: ends are squared off without any extension

With both EndType.Polygon and EndType.Joined, path closure will occur regardless of whether or not the first and last vertices in the path match.
