public class Size
extends IntPointer

\brief Template class for specifying the size of an image or rectangle.

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;
