方法: オブジェクトに複数の変換を適用する

  • [アーティクル]

この例では、TransformGroup を使用して、2 つ以上の Transform オブジェクトを 1 つの複合 Transform にグループ化する方法を示します。

例

次の例では、TransformGroup を使用して、ScaleTransform と RotateTransform を Button に適用します。

  <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>
