AnalysisRegion.Exclude Method (Rect)

Article
10/19/2012

Restricts the area of this AnalysisRegion to the portion of its area that does not intersect the specified rectangle.

Namespace: System.Windows.Ink
Assembly: IAWinFX (in IAWinFX.dll)

Syntax

'Declaration
Public Sub Exclude ( _
    rectangleToExclude As Rect _
)
'Usage
Dim instance As AnalysisRegion 
Dim rectangleToExclude As Rect

instance.Exclude(rectangleToExclude)

public void Exclude(
    Rect rectangleToExclude
)

public:
void Exclude(
    Rect rectangleToExclude
)

public function Exclude(
    rectangleToExclude : Rect
)

Parameters

rectangleToExclude
Type: System.Windows.Rect

The area to exclude.

Remarks

If the two areas do not intersect, this AnalysisRegion is unchanged.

The Exclude method throws an ArgumentOutOfRangeException if rectangleToExclude is outside of bounds defined by MinXY and MaxXY.

Examples

This example creates two AnalysisRegion objects. It uses the Intersect, Union, and Exclude methods to modify the objects' areas.

' 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));
