Detailed Description

template<typename T>
struct Simd::Point< T >

The Point structure defines the x- and y-coordinates of a point.

In order to have mutual conversion with OpenCV cv::Point and cv::Size types you have to define macro SIMD_OPENCV_ENABLE: 

#include "opencv2/core/core.hpp"
#define SIMD_OPENCV_ENABLE
#include "Simd/SimdPoint.hpp"

int main()
{
    typedef Simd::Point<ptrdiff_t> Point;

    cv::Size cvSize;
    cv::Point cvPoint;
    Point simdPoint;

    simdPoint = cvPoint;
    simdPoint = cvSize;
    cvSize = simdPoint;
    cvPoint = simdPoint;

    return 0;
}
