@Name(value="cv::Size_<int>") @NoOffset @Properties(inherit=opencv_core.class) public class Size extends IntPointer
The class includes two members called width and height. The structure can be converted to and from the old OpenCV structures CvSize and CvSize2D32f . The same set of arithmetic and comparison operations as for Point_ is available.
OpenCV defines the following Size_\<\> aliases:
typedef Size_<int> Size2i;
typedef Size2i Size;
typedef Size_<float> Size2f;
