Restreint le AnalysisRegion actif à une zone qui croise la région et le AnalysisRegion spécifié.

Espace de noms : System.Windows.Ink
Assembly : IAWinFX (dans IAWinFX.dll)

Syntaxe

'Déclaration
Public Sub Intersect ( _
    regionToIntersect As AnalysisRegion _
)
'Utilisation
Dim instance As AnalysisRegion
Dim regionToIntersect As AnalysisRegion

instance.Intersect(regionToIntersect)

public void Intersect(
    AnalysisRegion regionToIntersect
)

public:
void Intersect(
    AnalysisRegion^ regionToIntersect
)

public void Intersect(
    AnalysisRegion regionToIntersect
)

public function Intersect(
    regionToIntersect : AnalysisRegion
)

Paramètres

Type : System.Windows.Ink.AnalysisRegion
AnalysisRegion avec lequel effectuer l'intersection.

Notes

Si les deux zones ne se croisent pas, la nouvelle zone est vide.

Exemples

Cet exemple crée deux objets AnalysisRegion. Les méthodes Intersect, Union et Exclude sont utilisées pour modifier les zones des objets.

' 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));
