# getMinimalIod method

int getMinimalIod()

Gets the minimal interocular distance (IOD) in pixels required to perform a face encoding. Hint: Default value is 30 pixels. It is not recommended to change this value. Warning: Reducing the minimal required IOD to encode smaller face images may create unreliable face templates and significantly degrade recognition performances.

return Minimal interocular distance (IOD) in pixels required to perform a face encoding. throws FaceException An error has occurred during Face Library execution.

## Implementation

    int getMinimalIod() {
      Pointer<Int> pMinimalIod = calloc();
      try {
        var err = faceSDK.id3FaceEncoder_GetMinimalIod(_pHandle.value, pMinimalIod);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vMinimalIod = pMinimalIod.value;
        return vMinimalIod;
      } finally {
        calloc.free(pMinimalIod);
      }
    }
