Gewusst wie: Anwenden mehrerer Transformationen auf ein Objekt
In diesem Beispiel wird dargestellt, wie mithilfe von TransformGroup mindestens zwei Transform-Objekte in einem einzigen zusammengesetzten Transform-Objekt gruppiert werden können.
Beispiel
In folgendem Beispiel wird mithilfe von TransformGroup eine ScaleTransform und eine RotateTransform auf Button angewendet.

<StackPanel Margin="50">
<Button
RenderTransformOrigin="0.5,0.5"
HorizontalAlignment="Center">Click
<Button.RenderTransform>
<!-- TransformGroup enables you to apply multiple transforms. In
this example, the button is scaled and rotated. -->
<TransformGroup>
<!-- Triple the size (scale) of the button in the Y direction. -->
<ScaleTransform ScaleY="3" />
<!-- Rotate the button by 45 degrees. -->
<RotateTransform Angle="45" />
</TransformGroup>
</Button.RenderTransform>
</Button>
