| 释义 | CreatePolyPolygonRgn 语法： HRGN CreatePolyPolygonRgn( __in const POINT *lppt, __in const INT *lpPolyCounts, __in int nCount, __in int fnPolyFillMode ); CreatePolyPolygonRgn功能 该CreatePolyPolygonRgn函数创建一个区域的多边形系列组成。多边形可以重叠。 参数 lppt [in] 对一个Point结构数组的指针，定义在逻辑单元的多边形的顶点。指定的多边形连续。每个多边形推定关闭，每个顶点指定一次。 lpPolyCounts [in] 一个整数数组的指针，其中每个指定在数组中的多边形之一若干点所指向的lppt。 nCount [in] 整数的数组中的总人数指向lpPolyCounts。 fnPolyFillMode [in] 填充模式用于确定哪些像素在该区域。此参数可以是下列值之一。 ValueMeaning ALTERNATESelects替代模式(填补之间的奇数和偶数扫描线每双方多边形面积)。 WINDINGSelects绕组模式(填充与清盘值非零任何地区)。 如需有关这些模式的详细信息，请参阅SetPolyFillMode功能。 返回值 如果函数成功，返回值是处理该地区。 如果函数失败，返回值是零。 备注 当您不再需要HRGN对象，调用DeleteObject函数将其删除。 地区坐标表示为27位有符号整数。 要求： 最低支持：client－Windows 2000专业版 最低支持server－Windows 2000服务器 HeaderWingdi.h(头文件：winuser.h) LibraryGdi32.lib DLLGdi32.dll 参见 地区概况 区域函数 CreatePolygonRgn CreateRectRgn CreateRectRgnIndirect CreateRoundRectRgn ExtCreateRegion GetRegionData DeleteObject 点 SelectObject SetPolyFillMode 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＝＝CreatePolyPolygonRgn Function The CreatePolyPolygonRgn function creates a region consisting of a series of polygons. The polygons can overlap. Syntax HRGN CreatePolyPolygonRgn( __in const POINT *lppt, __in const INT *lpPolyCounts, __in int nCount, __in int fnPolyFillMode ); Parameters lppt [in] A pointer to an array of POINT structures that define the vertices of the polygons in logical units. The polygons are specified consecutively. Each polygon is presumed closed and each vertex is specified only once. lpPolyCounts [in] A pointer to an array of integers, each of which specifies the number of points in one of the polygons in the array pointed to by lppt. nCount [in] The total number of integers in the array pointed to by lpPolyCounts. fnPolyFillMode [in] The fill mode used to determine which pixels are in the region. This parameter can be one of the following values. ValueMeaning ALTERNATESelects alternate mode (fills area between odd-numbered and even-numbered polygon sides on each scan line). WINDINGSelects winding mode (fills any region with a nonzero winding value). For more information about these modes, see the SetPolyFillMode function. Return Value If the function succeeds, the return value is the handle to the region. If the function fails, the return value is zero. Remarks When you no longer need the HRGN object, call the DeleteObject function to delete it. Region coordinates are represented as 27-bit signed integers.
