## Implementation

    int getHatThreshold() {
      Pointer<Int> pHatThreshold = calloc();
      try {
        var err = faceSDK.id3FacePortraitProcessor_GetHatThreshold(_pHandle.value, pHatThreshold);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vHatThreshold = pHatThreshold.value;
        return vHatThreshold;
      } finally {
        calloc.free(pHatThreshold);
      }
    }
