Member Function Documentation

◆ AdaptiveSubdivide()

void tools::PolyPolygon::AdaptiveSubdivide ( tools::PolyPolygon &  rResult) const

Adaptive subdivision of polygons with curves.

This method adaptively subdivides bezier arcs within the polygon to straight line segments and returns the resulting polygon.

Parameters
rResultThe resulting subdivided polygon

If the polygon is in device coordinates, then the difference between the subdivided and the original polygon is guaranteed to be smaller than one pixel.
