StrokeCollection.GetBounds Método

Definição

Namespace:

System.Windows.Ink

Assembly:

PresentationCore.dll

Retorna os limites dos traços na coleção.

public:
 System::Windows::Rect GetBounds();

public System.Windows.Rect GetBounds ();

member this.GetBounds : unit -> System.Windows.Rect

Public Function GetBounds () As Rect

Retornos

Rect

Um Rect que contém os limites dos traços no StrokeCollection.

Exemplos

O exemplo a seguir demonstra como obter os limites do StrokeCollection controle e desenhá-los no controle. Este exemplo pressupõe que haja um InkCanvas chamado inkCanvas1.

public void GetBounds()
{
    Rect bounds = inkCanvas1.Strokes.GetBounds();

    Rectangle boundsShape = new Rectangle();
    boundsShape.Width = bounds.Width;
    boundsShape.Height = bounds.Height;
    boundsShape.Stroke = Brushes.Red;

    InkCanvas.SetTop(boundsShape, bounds.Top);
    InkCanvas.SetLeft(boundsShape, bounds.Left);

    inkCanvas1.Children.Add(boundsShape);
}

Public Sub GetBounds()
    Dim bounds As Rect = inkCanvas1.Strokes.GetBounds()

    Dim boundsShape As Rectangle = New Rectangle()
    boundsShape.Width = bounds.Width
    boundsShape.Height = bounds.Height
    boundsShape.Stroke = Brushes.Red

    InkCanvas.SetTop(boundsShape, bounds.Top)
    InkCanvas.SetLeft(boundsShape, bounds.Left)

    inkCanvas1.Children.Add(boundsShape)
End Sub

Comentários

O GetBounds método retorna um Rect que usa a aparência do renderizado Stroke. Por exemplo, se Stroke tiver 10 pixels independentes de exibição (DIP), ele Rect incluirá toda a largura do Stroke.
