释义 | Pie 语法: BOOL Pie( __in HDC hdc, __in int nLeftRect, __in int nTopRect, __in int nRightRect, __in int nBottomRect, __in int nXRadial1, __in int nYRadial1, __in int nXRadial2, __in int nYRadial2 ); 馅饼功能 馅饼函数绘制的饼形楔由椭圆和两个子午线交叉范围内。概述馅饼使用目前的笔和使用当前画笔填补。 参数 hdc [in] 一个句柄,设备上下文。 nLeftRect [in] 的x坐标,在逻辑坐标,对边界矩形的左上角。 nTopRect [in] 在y坐标,在逻辑坐标,对边界矩形的左上角。 nRightRect [in] 的x坐标,在逻辑坐标下,的边界矩形右下角。 nBottomRect [in] 在y坐标,在逻辑坐标下,的边界矩形右下角。 nXRadial1 [in] 的x坐标,在逻辑坐标,对第一个径向端点。 nYRadial1 [in] 在y坐标,在逻辑坐标,对第一个径向端点。 nXRadial2 [in] 的x坐标,在逻辑坐标,对第二个径向端点。 nYRadial2 [in] 在y坐标,在逻辑坐标,对第二个径向端点。 返回值 如果函数成功,返回值为非零。 如果函数失败,返回值是零。 备注 该饼曲线的定义是一个椭圆适合指定的边界矩形。开始时的曲线相交的椭圆第一径向和延伸逆时针的地步椭圆相交的第二个径向点。 当前位置是既没使用也没更新功能的馅饼。 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 填充形状概述 填充形状函数 AngleArc 弧 ArcTo 和弦 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==Pie Function The Pie function draws a pie-shaped wedge bounded by the intersection of an ellipse and two radials. The pie is outlined by using the current pen and filled by using the current brush. Syntax BOOL Pie( __in HDC hdc, __in int nLeftRect, __in int nTopRect, __in int nRightRect, __in int nBottomRect, __in int nXRadial1, __in int nYRadial1, __in int nXRadial2, __in int nYRadial2 ); Parameters hdc [in] A handle to the device context. nLeftRect [in] The x-coordinate, in logical coordinates, of the upper-left corner of the bounding rectangle. nTopRect [in] The y-coordinate, in logical coordinates, of the upper-left corner of the bounding rectangle. nRightRect [in] The x-coordinate, in logical coordinates, of the lower-right corner of the bounding rectangle. nBottomRect [in] The y-coordinate, in logical coordinates, of the lower-right corner of the bounding rectangle. nXRadial1 [in] The x-coordinate, in logical coordinates, of the endpoint of the first radial. nYRadial1 [in] The y-coordinate, in logical coordinates, of the endpoint of the first radial. nXRadial2 [in] The x-coordinate, in logical coordinates, of the endpoint of the second radial. nYRadial2 [in] The y-coordinate, in logical coordinates, of the endpoint of the second radial. Return Value If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. Remarks The curve of the pie is defined by an ellipse that fits the specified bounding rectangle. The curve begins at the point where the ellipse intersects the first radial and extends counterclockwise to the point where the ellipse intersects the second radial. The current position is neither used nor updated by the Pie function.
