Method Xor

path_intersection.go:181–183

Xor returns the boolean path operation of path p XOR q, i.e. the symmetric difference of both. It removes all self-intersections and overlapping areas, orients all filling paths CCW and all holes CW, and tries to separate paths as much as possible. Paths are grouped by the filling/outer ring followe

(q *Path)

// flat. Path q is implicitly closed. It runs in O((n + k) log n), with n the number of segments,
// and k the number of intersections.
func (p *Path) Xor(q *Path) *Path {
	return bentleyOttmann(p.Split(), q.Split(), opXOR, NonZero).Merge()
}

// Xor is the same as Path.Xor, but faster if paths are already split. Each resulting path
// is a single filling path followed by its holes as subpaths.
