I do a lot of this and there is no generic way. The rect might be a rect or 4 lines or a polyline 3 or 4 (or 5 for overlaps). It migh be drawn twice for emplhasis . I have have some heuristics for creating probable rects. in http://github.com/petermr/ami3 If you are serious and doing a *lot* I can show you where to find them.
