设计逻辑坐标原点是,以后所用的GDI函数是否用逻辑参数还是设备参数?
设计设备坐标原点时,以后所用的GDI函数是否用设备参数还是逻辑参数

The SetWindowOrgEx function specifies which window point maps to the viewport origin (0,0).
BOOL SetWindowOrgEx(
HDC hdc, // handle to device context
int X, // new x-coordinate of window origin
int Y, // new y-coordinate of window origin
LPPOINT lpPoint // original window origin
);
The SetViewportOrgEx function specifies which device point maps to the window origin (0,0).
BOOL SetViewportOrgEx(
HDC hdc, // handle to device context
int X, // new x-coordinate of viewport origin
int Y, // new y-coordinate of viewport origin
LPPOINT lpPoint // original viewport origin
);
一个是设备，一个是窗口！
