Detailed Description#

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

The class includes two members called width and height. The same set of arithmetic and comparison operations as for Point_ is available.

For a 1d matrix, the size is (width, 1) and for a 0d matrix, it is (1, 1).

For an empty matrix, it is (0, 0).

OpenCV defines the following Size_<> aliases:

typedef Size_<int> Size2i;
typedef Size2i Size;
typedef Size_<float> Size2f;
