示例1: clop
inline pos2<T> clop(const pos2<T>& pos, const rect<T>& r, T resolution=1) {
pos2<T> cloped(pos);
if (cloped.x_ >= r.right()) cloped.x_ = r.right() - resolution;
if (cloped.y_ >= r.bottom()) cloped.y_ = r.bottom() - resolution;
if (cloped.x_ < r.left()) cloped.x_ = r.left();

}示例2: contains
constexpr bool contains(
rect< PositionType, SizeType > const& reference,
rect< PositionType, SizeType > const& test
){
return
