10/28/2008

将此 AnalysisRegion 的区域扩展为它与指定的 AnalysisRegion 合并所形成的区域。

命名空间： Microsoft.Ink
程序集： Microsoft.Ink.Analysis（在 Microsoft.Ink.Analysis.dll 中）

语法

声明
Public Sub Union ( _
    regionToUnion As AnalysisRegion _
)
用法
Dim instance As AnalysisRegion
Dim regionToUnion As AnalysisRegion

instance.Union(regionToUnion)

public void Union(
    AnalysisRegion regionToUnion
)

public:
void Union(
    AnalysisRegion^ regionToUnion
)

public void Union(
    AnalysisRegion regionToUnion
)

public function Union(
    regionToUnion : AnalysisRegion
)

参数

regionToUnion
类型：Microsoft.Ink.AnalysisRegion
要与之合并的 AnalysisRegion。

备注

如果任一个区域无限，则新区域也无限。

示例

此示例创建两个 AnalysisRegion 对象。它使用 Intersect、Union 和 Exclude 方法来修改这两个对象的区域。

' Create an infinite AnalysisRegion.
Dim theFirstAnalysisRegion As New Microsoft.Ink.AnalysisRegion()

' Create a finite AnalysisRegion.
Dim theSecondAnalysisRegion As New Microsoft.Ink.AnalysisRegion( _
    New System.Drawing.Rectangle(205, 205, 2054, 1027))

' Extend an AnalysisRegion using the Union method and an AnalysisRegion.
theFirstAnalysisRegion.Union(theSecondAnalysisRegion)

' Extend an AnalysisRegion using the Union method and a rectangle.
theFirstAnalysisRegion.Union(New Rectangle(0, 2054, 2054, 1027))

' Restrict an AnalysisRegion using the Intersect method and an AnalysisRegion.
theFirstAnalysisRegion.Intersect(theSecondAnalysisRegion)

' Restrict an AnalysisRegion using the Intersect method and a rectangle.
theFirstAnalysisRegion.Intersect(New Rectangle(750, 1000, 2500, 1500))

' Modify an AnalysisRegion using the Exclude method and an AnalysisRegion.
theFirstAnalysisRegion.Exclude(theSecondAnalysisRegion)

' Modify an AnalysisRegion using the Exclude method and a rectangle.
theFirstAnalysisRegion.Exclude(New Rectangle(750, 1000, 500, 500))

            // Create an infinite AnalysisRegion.
            Microsoft.Ink.AnalysisRegion theFirstAnalysisRegion =
                new Microsoft.Ink.AnalysisRegion();

            // Create a finite AnalysisRegion.
            Microsoft.Ink.AnalysisRegion theSecondAnalysisRegion =
                new Microsoft.Ink.AnalysisRegion(
                    new System.Drawing.Rectangle(205, 205, 2054, 1027));

            // Extend an AnalysisRegion using the Union method and an AnalysisRegion.
            theFirstAnalysisRegion.Union(theSecondAnalysisRegion);

            // Extend an AnalysisRegion using the Union method and a rectangle.
            theFirstAnalysisRegion.Union(new Rectangle(0, 2054, 2054, 1027));

            // Restrict an AnalysisRegion using the Intersect method and an AnalysisRegion.
            theFirstAnalysisRegion.Intersect(theSecondAnalysisRegion);

            // Restrict an AnalysisRegion using the Intersect method and a rectangle.
            theFirstAnalysisRegion.Intersect(new Rectangle(750, 1000, 2500, 1500));

            // Modify an AnalysisRegion using the Exclude method and an AnalysisRegion.
            theFirstAnalysisRegion.Exclude(theSecondAnalysisRegion);

            // Modify an AnalysisRegion using the Exclude method and a rectangle.
            theFirstAnalysisRegion.Exclude(new Rectangle(750, 1000, 500, 500));
