getMaximumHeadWidthRatio method

int getMaximumHeadWidthRatio()

Gets the value indicating if the image width is conform to the (image width / head width) ratio of 7:5. The head width is defined as the distance between the left and right ears. For ICAO compliance, the value must be in the range 50 to 75. Hint: Default value is 75.

return Value indicating if the image width is conform to the (image width / head width) ratio of 7:5. throws FaceException An error has occurred during Face Library execution.

Implementation

int getMaximumHeadWidthRatio() {
  Pointer<Int> pMaximumHeadWidthRatio = calloc();
  try {
    var err = faceSDK.id3FacePortraitProcessor_GetMaximumHeadWidthRatio(_pHandle.value, pMaximumHeadWidthRatio);
    if (err != FaceError.success.value) {
      throw FaceException(err);
    }
    final vMaximumHeadWidthRatio = pMaximumHeadWidthRatio.value;
    return vMaximumHeadWidthRatio;
  } finally {
    calloc.free(pMaximumHeadWidthRatio);
  }
