对任何坐标类型多维地区的模板类

一个几年前，我曾写了一个视频挂钩驱动程序排序。在那里，我需要：

（其中包括）地区的业务处理，如发现路口，减，加入区域，等

有一个在Win32 API的这些地区的支持。区域功能是用于操作CreateRectRgn，CreateEllipticRgn，EqualRgn，GetRgnBox，OffsetRgn，CombineRgn，等这个API是相当难看，在我看来不舒服。它的实施是隐蔽，你要手柄（HRGN）来使用它。当你需要，例如，要找到一两个区域相交，你必须创建一个新的空区处理，然后再“补”的交集了。-A couple of years ago, I had to write a sort of a video hook driver. And there, I needed (among other things) to handle region operations, such as finding intersections, subtracting, joining regions, and etc.



There s a support for such regions in Win32 API. Functions for manipulating regions are CreateRectRgn, CreateEllipticRgn, EqualRgn, GetRgnBox, OffsetRgn, CombineRgn, and etc. This API is pretty ugly and uncomfortable, in my opinion. Its implementation is concealed, and you have to mess with handles (HRGN) to work with it. When you need, for instance, to find an intersection of two regions, you have to create a new empty region handle, and then "fill" it with the intersection. That is:
