Created attachment 261 [details] XOR in GDIPlus example Add a Polyline function in GDIPlus that can XOR to remove the polyline previously drawn. We are using an internal GDI Canvas (IXORCanvas) in GDIPlus to draw both the Zoom rectangle and the DrawLineTool. There's also a Polygon function in GDIPlus that uses this IXORCanvas, but this function closes the array of points. If the can't have a Polyline function with GDIPlus and AntiAlias, maybe the only way to go would be to have a Polyline function in GDIPlus calling IXORCanvas.
