如何：向对象应用多个变换
更新：2007 年 11 月
此示例演示如何使用 TransformGroup 将两个或更多 Transform 对象并为一个复合 Transform。
示例
下面的示例使用 TransformGroup 将 ScaleTransform 和 RotateTransform 应用于 Button。
<Page

<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>
</StackPanel>

// Create a Button that will have two transforms applied to it.
Button myButton = new Button();
myButton.Content = "Click";

myButton.RenderTransformOrigin = new Point(0.5,0.5);
// Create a transform to scale the size of the button.
ScaleTransform myScaleTransform = new ScaleTransform();
// Set the transform to triple the scale in the Y direction.
myScaleTransform.ScaleY = 3;
// Create a transform to rotate the button
RotateTransform myRotateTransform = new RotateTransform();
// Set the rotation of the transform to 45 degrees.
myRotateTransform.Angle = 45;
// Create a TransformGroup to contain the transforms
// and add the transforms to it.
TransformGroup myTransformGroup = new TransformGroup();
myTransformGroup.Children.Add(myScaleTransform);
myTransformGroup.Children.Add(myRotateTransform);
// Associate the transforms to the button.
myButton.RenderTransform = myTransformGroup;
// Create a StackPanel which will contain the Button.
StackPanel myStackPanel = new StackPanel();
myStackPanel.Margin = new Thickness(50);
myStackPanel.Children.Add(myButton);
this.Content = myStackPanel;
}
