示例1: getRect
Rect getRect(const Mat im, const string win_name)
{
win_name_ = win_name;
im_select = im;
tl_set = false;
br_set = false;
setMouseCallback(win_name, onMouse);
//Dummy call to get drawing right
onMouse(0,0,0,0,0);
while(!br_set)
{
cvWaitKey(10);
}
setMouseCallback(win_name, NULL);
im_select.release(); //im_select is in global scope, so we call release manually
return Rect(tl,br);
