possible to convert value of a Point to string? opencv c++

edit

thanks it works!

Just want to add a standard way of converting everything except a string into a string in C++, is done by using the stringstream operator. A small example in this case:

Point p(5,5);
stringstream temp;
temp << "(" << p.x << "," << p.y << ")";
putText(image, temp.str(), maxLoc,FONT_HERSHEY_COMPLEX_SMALL, 0.8, cvScalar(255, 255, 204), 1, CV_AA);

This workaround of manually writing each element to the stringstream is not necessary for every OpenCV object out there. Some of them, like mats, can be directly written using the << operator. It all depends if it is implemented for that object.
