VecVecPoint2f.generate constructor

VecVecPoint2f.generate(
  1. int length,
  2. VecPoint2f generator(
    1. int i
    ), {
  3. bool dispose = true,
})

Implementation

factory VecVecPoint2f.generate(int length, VecPoint2f Function(int i) generator, {bool dispose = true}) {
  final p = ccore.std_VecVecPoint2f_new(length);
  int count = 0;
  for (var i = 0; i < length; i++) {
    final v = generator(i);
    count += v.length;
    ccore.std_VecVecPoint2f_set(p, i, v.ref);
    if (dispose) v.dispose();
  }
  return VecVecPoint2f.fromPointer(p, externalSize: count * ffi.sizeOf<cvg.CvPoint2f>());
