      try {
        var err = faceSDK.id3FacePortrait_GetMouthOpening(_pHandle.value, pMouthOpening);
        if (err != FaceError.success.value) {
          throw FaceException(err);

        final vMouthOpening = pMouthOpening.value;
        return vMouthOpening;
      } finally {
        calloc.free(pMouthOpening);
      }
