AnalysisRegion.Exclude 方法 (Rect)

项目
11/04/2008

将此 AnalysisRegion 的区域限制为其区域与指定矩形不相交的部分。

命名空间： System.Windows.Ink
程序集： IAWinFX（在 IAWinFX.dll 中）

语法

声明
Public Sub Exclude ( _
    rectangleToExclude As Rect _
)
用法
Dim instance As AnalysisRegion
Dim rectangleToExclude As Rect

instance.Exclude(rectangleToExclude)

public void Exclude(
    Rect rectangleToExclude
)

public:
void Exclude(
    Rect rectangleToExclude
)

public void Exclude(
    Rect rectangleToExclude
)

public function Exclude(
    rectangleToExclude : Rect
)

参数

rectangleToExclude
类型：System.Windows.Rect
要排除的区域。

备注

如果两个区域不相交，则此 AnalysisRegion 不变。

如果 rectangleToExclude 在 MinXY 和 MaxXY 所定义的边界之外，则 Exclude 方法会引发 ArgumentOutOfRangeException。

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 AnalysisRegion()
' Create a finite AnalysisRegion.
Dim theSecondAnalysisRegion As New AnalysisRegion(New Rect(100, 100, 200, 200))
' 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 Rect(100, 100, 200, 200))

' 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 Rect(100, 100, 200, 200))

' 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 Rect(100, 100, 200, 200))

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

// Create a finite AnalysisRegion.
AnalysisRegion theSecondAnalysisRegion =
    new AnalysisRegion(
        new Rect(100, 100, 200, 200));

// 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 Rect(100, 100, 200, 200));

// 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 Rect(100, 100, 200, 200));

// 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 Rect(100, 100, 200, 200));
