      Pointer<Int> pLeftEyeOpening = calloc();
      try {
        var err = faceSDK.id3FacePortrait_GetLeftEyeOpening(_pHandle.value, pLeftEyeOpening);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vLeftEyeOpening = pLeftEyeOpening.value;
        return vLeftEyeOpening;
      } finally {
        calloc.free(pLeftEyeOpening);
      }
    }
