getCropIodRatio method

double getCropIodRatio()

Gets the ratio between the interocular distance (IOD) and the image width for ICAO portrait cropping. Must be in the range )0;1(. Hint: Default value is 0.25.

return Ratio between the interocular distance (IOD) and the image width for ICAO portrait cropping. Must be in the range )0;1(. throws FaceException An error has occurred during Face Library execution.

Implementation

    if (err != FaceError.success.value) {
      throw FaceException(err);
    }
    final vCropIodRatio = pCropIodRatio.value;
    return vCropIodRatio;
  } finally {
