[Boost-users] [Polygon] attaching data to polygon boundary segments

Dear Boost community, I would like to process 2D geometry for a finite element solver using boost.polygon. I programmed it, it's working fine. I use the polygon_data and polygon_set_data types from boost.polygon. Now I would like to attach information to the boundary segments. Then I'd like to do boolean operations. At the end I would like to have the boundary information merged. Is this possible with boost.polygon? A attached a little drawing of what behavior I would like to achieve, colors code the boundary markers. thanks a lot in advance, Best regards, Andreas
