## Implementation

    int getMouthVisibility() {
      Pointer<Int> pMouthVisibility = calloc();
      try {
        var err = faceSDK.id3FacePortrait_GetMouthVisibility(_pHandle.value, pMouthVisibility);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vMouthVisibility = pMouthVisibility.value;
        return vMouthVisibility;
      } finally {
        calloc.free(pMouthVisibility);
      }
    }
