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

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in microsoft.ink.analysis.dll)

Syntax

'Declaration
Public Sub Union ( _
    regionToUnion As AnalysisRegion _
)
'Usage
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
)

Not applicable.

Parameters

regionToUnion
The AnalysisRegion with which to combine.

Remarks

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

Example

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 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));
