# getCropEyePositionRatio method

double getCropEyePositionRatio()

Gets the ratio between the vertical eye position and the image height for ICAO portrait cropping. Must be in the range )0;1(. Hint: Default value is 0.45.

return Ratio between the vertical eye position and the image height for ICAO portrait cropping. Must be in the range )0;1(. throws FaceException An error has occurred during Face Library execution.

## Implementation

    double getCropEyePositionRatio() {
      Pointer<Float> pCropEyePositionRatio = calloc();
      try {
        var err = faceSDK.id3FacePortraitProcessor_GetCropEyePositionRatio(_pHandle.value, pCropEyePositionRatio);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vCropEyePositionRatio = pCropEyePositionRatio.value;
        return vCropEyePositionRatio;
      } finally {
        calloc.free(pCropEyePositionRatio);
      }
    }
