int getLeftEyeVisibility()

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

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

## Implementation

    int getLeftEyeVisibility() {
      Pointer<Int> pLeftEyeVisibility = calloc();
      try {
        var err = faceSDK.id3FacePortrait_GetLeftEyeVisibility(_pHandle.value, pLeftEyeVisibility);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vLeftEyeVisibility = pLeftEyeVisibility.value;
        return vLeftEyeVisibility;
      } finally {
        calloc.free(pLeftEyeVisibility);
      }
    }
