Implementation

double compare(Image cmpImage) {
  Pointer<Float> pResult = calloc();
  try {
    var err = faceSDK.id3FaceImage_Compare(_pHandle.value, cmpImage.handle, pResult);
    if (err != FaceError.success.value) {
      throw FaceException(err);
    }
    final vResult = pResult.value;
    return vResult;
  } finally {
    calloc.free(pResult);
  }
}
