[Boost-users] Geometry buffer algorithm: complete or not?

I was looking here: http://www.boost.org/doc/libs/1_52_0/libs/geometry/doc/html/geometry/referen... And saw this: "The current implemetation only enlarges a box, which is not defined by OGC. A next version of the library will contain a more complete implementation" It looks like Boost::Geometry is incapable of buffering an arbitrary polygon. But various forum discussions refer to the buffer() algorithm like it actually works for the general case. Which is correct? John Lilley
