CGAL::Polyline_simplification_2::Stop_below_count_ratio_threshold Class Reference

#include <CGAL/Polyline_simplification_2/Stop_below_count_ratio_threshold.h>

Definition

This class is a stop predicate returning true when the percentage of remaining vertices is smaller than a certain threshold.

Is model of

PolylineSimplificationStopPredicate

Public Member Functions
	Stop_below_count_ratio_threshold (double threshold)
	Initializes it with the given threshold value.

Returns true when ( current_count / initial_count ) is smaller or equal than the threshold.

Template Parameters

CDT	must be CGAL::Constrained_Delaunay_triangulation_2 with a vertex type that is model of PolylineSimplificationVertexBase_2.
