◆ AdaptiveSubdivide()

void tools::Polygon::AdaptiveSubdivide	(	tools::Polygon &	rResult,
		const double	d = `1.0`
	)		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

rResult	The resulting subdivided polygon
d	This parameter controls the amount of subdivision. The original curve is guaranteed to not differ by more than this amount per bezier segment from the subdivided lines. Concretely, if the polygon is in device coordinates and d equals 1.0, then the difference between the subdivided and the original polygon is guaranteed to be smaller than one pixel.
