Article
10/07/2012

Expands the area of this AnalysisRegionBase to the area created by its union with the specified AnalysisRegionBase.

Namespace: System.Windows.Ink.AnalysisCore
Assembly: IACore (in IACore.dll)

Syntax

'Declaration
Public Sub Union ( _
    regionToUnion As AnalysisRegionBase _
)
'Usage
Dim instance As AnalysisRegionBase 
Dim regionToUnion As AnalysisRegionBase

instance.Union(regionToUnion)

public void Union(
    AnalysisRegionBase regionToUnion
)

public:
void Union(
    AnalysisRegionBase^ regionToUnion
)

public function Union(
    regionToUnion : AnalysisRegionBase
)

Parameters

regionToUnion
Type: System.Windows.Ink.AnalysisCore.AnalysisRegionBase

The area with which to combine.

Remarks

If either area is infinite, the new area is also infinite.

Examples

The example uses Exclude, Intersect, and Union to modify the area of an existing AnalysisRegionBase, named theFirstAnalysisRegionBase.

' Extend an AnalysisRegionBase using the Union method and 
' an AnalysisRegionBase.
theFirstAnalysisRegionBase.Union(theSecondAnalysisRegionBase)

' Extend an AnalysisRegionBase using the Union method and a rectangle.
theFirstAnalysisRegionBase.Union(0, 500, 3000, 3500)

' Restrict an AnalysisRegionBase using the Intersect method and 
' an AnalysisRegionBase.
theFirstAnalysisRegionBase.Intersect(theSecondAnalysisRegionBase)

' Restrict an AnalysisRegionBase using the Intersect method and a rectangle.
theFirstAnalysisRegionBase.Intersect(1000, 1000, 5000, 5000)

' Restrict an AnalysisRegionBase using the Exclude method and 
' an AnalysisRegionBase.
theFirstAnalysisRegionBase.Exclude(theSecondAnalysisRegionBase)

' Modify an AnalysisRegionBase using the Exclude method and a rectangle.
theFirstAnalysisRegionBase.Exclude(1500, 1500, 2500, 2500)

// Extend an AnalysisRegionBase using the Union method and 
// an AnalysisRegionBase.
theFirstAnalysisRegionBase.Union(theSecondAnalysisRegionBase);

// Extend an AnalysisRegionBase using the Union method and a rectangle.
theFirstAnalysisRegionBase.Union(0, 500, 3000, 3500);

// Restrict an AnalysisRegionBase using the Intersect method and 
// an AnalysisRegionBase.
theFirstAnalysisRegionBase.Intersect(theSecondAnalysisRegionBase);

// Restrict an AnalysisRegionBase using the Intersect method and a rectangle.
theFirstAnalysisRegionBase.Intersect(1000, 1000, 5000, 5000);

// Restrict an AnalysisRegionBase using the Exclude method and 
// an AnalysisRegionBase.
theFirstAnalysisRegionBase.Exclude(theSecondAnalysisRegionBase);

// Modify an AnalysisRegionBase using the Exclude method and a rectangle.
theFirstAnalysisRegionBase.Exclude(1500, 1500, 2500, 2500);
