approxPolyN function

VecPoint approxPolyN(
  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

VecPoint approxPolyN(
  VecPoint curve,
  int nsides, {
  double epsilon_percentage = -1.0,
  bool ensure_convex = true,
}) {
  final vec = VecPoint();
  cvRun(
    () => cimgproc.cv_approxPolyN(curve.ref, nsides, epsilon_percentage, ensure_convex, vec.ptr, ffi.nullptr),
  );
  return vec;
}
