It is expensive because it tries to be so correct. getB2DRange() is also optimized. It does not adaptive subdivide internally as You might think, but uses Your (and thb's) extreme value search on a bezier segment to get a very correct result very fast. Only points at the extremes (and only when the bezier segment is not already in the range) are numerically calculated, the polygon is in no way processed or changed. Also, the B2DRange is buffered at the polygon instance and reused. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
