(bool, VecPoint) detect(
  1. InputArray input, {
  2. VecPoint? points,
})

Detect detects QR code in image and returns the quadrangle containing the code.

Implementation

(bool ret, VecPoint points) detect(InputArray input, {VecPoint? points}) {
  points ??= VecPoint();
  final ret = calloc<ffi.Bool>();
  cvRun(() => cobjdetect.cv_QRCodeDetector_detect(ref, input.ref, points!.ptr, ret, ffi.nullptr));
  final rval = (ret.value, points);
  calloc.free(ret);
  return rval;
}
