释义 | IntersectRect 语法: BOOL IntersectRect( __out LPRECT lprcDst, __in const RECT *lprcSrc1, __in const RECT *lprcSrc2 ); IntersectRect功能 该IntersectRect函数计算两个源矩形和地方的交叉矩形坐标到目标矩形的交集。如果源矩形不相交,一个空矩形(在所有坐标设置为零)是到目标矩形上。 参数 lprcDst [out] 一个矩形结构,得到了矩形的交集指针指向的lprcSrc1和lprcSrc2参数。这个参数不能为NULL。 lprcSrc1 [in] 一个RECT结构,它包含第一个源矩形的指针。 lprcSrc2 [in] 一个RECT结构,它包含了第二个源矩形的指针。 返回值 如果矩形相交,返回非零值。 如果矩形不相交,返回值是零。 备注 因为应用程序可以使用不同的目的矩形,矩形的职能不使用明确的衡量单位。相反,所有矩形坐标和尺寸在签署的,逻辑值给出。映射模式和在该矩形用来确定测量装置的功能。 实例 有关示例,请参阅使用矩形。 要求: 最低支持:client-Windows 2000专业版 最低支持server-Windows 2000服务器 HeaderWinuser.h(头文件:winuser.h) LibraryUser32.lib DLLUser32.dll 参见 矩形概述 矩形函数 InflateRect OffsetRect RECT UnionRect 如果有任何问题和意见,请发送给微软(wsddocfb@microsoft.com) 生成日期:2009年7月11日 ==英文原文==IntersectRect Function The IntersectRect function calculates the intersection of two source rectangles and places the coordinates of the intersection rectangle into the destination rectangle. If the source rectangles do not intersect, an empty rectangle (in which all coordinates are set to zero) is placed into the destination rectangle. Syntax BOOL IntersectRect( __out LPRECT lprcDst, __in const RECT *lprcSrc1, __in const RECT *lprcSrc2 ); Parameters lprcDst [out] A pointer to the RECT structure that is to receive the intersection of the rectangles pointed to by the lprcSrc1 and lprcSrc2 parameters. This parameter cannot be NULL. lprcSrc1 [in] A pointer to the RECT structure that contains the first source rectangle. lprcSrc2 [in] A pointer to the RECT structure that contains the second source rectangle. Return Value If the rectangles intersect, the return value is nonzero. If the rectangles do not intersect, the return value is zero. Remarks Because applications can use rectangles for different purposes, the rectangle functions do not use an explicit unit of measure. Instead, all rectangle coordinates and dimensions are given in signed, logical values. The mapping mode and the function in which the rectangle is used determine the units of measure.
