int getNoseVisibility()

Gets the value estimating the visibility of the nose. -1 if not computed. The range is 0-100, 100 meaning the nose is fully visible.

return Value estimating the visibility of the nose. -1 if not computed. The range is 0-100, 100 meaning the nose is fully visible. throws FaceException An error has occurred during Face Library execution.

## Implementation

    int getNoseVisibility() {
      Pointer<Int> pNoseVisibility = calloc();
      try {
        var err = faceSDK.id3FacePortrait_GetNoseVisibility(_pHandle.value, pNoseVisibility);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vNoseVisibility = pNoseVisibility.value;
        return vNoseVisibility;
      } finally {
        calloc.free(pNoseVisibility);
      }
    }
