approxPolyNAsync function

Future<VecPoint> approxPolyNAsync(
  1. VecPoint curve,
  2. int nsides, {
  3. double epsilon_percentage = -1.0,
  4. bool ensure_convex = true,
})

ApproxPolyN approximates a polygon with a convex hull with a specified accuracy and number of sides.

Implementation

Future<VecPoint> approxPolyNAsync(
  VecPoint curve,
  int nsides, {
  double epsilon_percentage = -1.0,
  bool ensure_convex = true,
}) async {
  final vec = VecPoint();
  return cvRunAsync0(
    (callback) =>
        cimgproc.cv_approxPolyN(curve.ref, nsides, epsilon_percentage, ensure_convex, vec.ptr, callback),
    (c) {
      return c.complete(vec);
    },
  );
}
