- //----------------------------------------------------------vertex_sequence
- // Modified agg::pod_bvector. The data is interpreted as a sequence
- // of vertices. It means that the type T must expose:
- //
- // bool T::operator() (const T& val)
- //
- // that is called every time new vertex is being added. The main purpose
- // of this operator is the possibility to calculate some values during
- // adding and to return true if the vertex fits some criteria or false if
- // it doesn't. In the last case the new vertex is not added.
- //
- // The simple example is filtering coinciding vertices with calculation
- // of the distance between the current and previous ones:
- //
- // struct vertex_dist
- // {
- // double x;
- // double y;
- // double dist;
- //
- // vertex_dist() {}
- // vertex_dist(double x_, double y_) :
- // x(x_),
- // y(y_),
- // dist(0.0)
- // {
- // }
- //
- // bool operator () (const vertex_dist& val)
- // {
- // return (dist = calc_distance(x, y, val.x, val.y)) > EPSILON;
- // }
- // };
- //
- // Function close() calls this operator and removes the last vertex if
- // necessary.
