只在Silverlight中使用CompositeTransform？

Question

CompositeTransform僅用於Silverlight的？無論如何，我們可以在WPF或其他同等替代品中使用它嗎？

Answer 1

有一個在WPF沒有CompositeTransform但有一個TransformGroup。因此，一個等同替換爲含有以該順序ScaleTransform，SkewTransform，RotateTransform和TranslateTransform一個TransformGroup。

Answer 2

這裏是一個好得多的解決方案，如果你是肛門有關代碼清潔度：

它很容易對眼睛和，因爲它只是返回的TransformGroup，你仍然可以使用混合設計師一起工作通過變換進行動畫處理！

<Rectangle Width="100" Height="100" Fill="LightGreen" 
     RenderTransform="{data:CompositeTransform ScaleX=2.5, ScaleY=1, SkewX=-60, Rotation=145}" 
     RenderTransformOrigin="0.5,0.5" /> 

實現：

public class CompositeTransformExtension : MarkupExtension 
{ 
    public double CenterX 
    { 
     get { return _scale.CenterX; } 
     set 
     { 
      _scale.CenterX = value; 
      _skew.CenterX = value; 
      _rotate.CenterX = value; 

     } 
    } 

    public double CenterY 
    { 
     get { return _scale.CenterY; } 
     set 
     { 
      _scale.CenterY = value; 
      _skew.CenterY = value; 
      _rotate.CenterY = value; 
     } 
    } 

    public double ScaleX 
    { 
     get { return _scale.ScaleX; } 
     set { _scale.ScaleX = value; } 
    } 

    public double ScaleY 
    { 
     get { return _scale.ScaleY; } 
     set { _scale.ScaleY = value; } 
    } 

    public double SkewX 
    { 
     get { return _skew.AngleX; } 
     set { _skew.AngleX = value; } 
    } 

    public double SkewY 
    { 
     get { return _skew.AngleY; } 
     set { _skew.AngleY = value; } 
    } 

    public double Rotation 
    { 
     get { return _rotate.Angle; } 
     set { _rotate.Angle = value; } 
    } 

    public double TranslateX 
    { 
     get { return _translate.X; } 
     set { _translate.X = value; } 
    } 

    public double TranslateY 
    { 
     get { return _translate.Y; } 
     set { _translate.Y = value; } 
    } 

    private ScaleTransform _scale = new ScaleTransform(); 
    private SkewTransform _skew = new SkewTransform(); 
    private RotateTransform _rotate = new RotateTransform(); 
    private TranslateTransform _translate = new TranslateTransform(); 

    public CompositeTransformExtension() 
    { 
    } 

    public override object ProvideValue(IServiceProvider serviceProvider) 
    { 
     var group = new TransformGroup(); 

     group.Children.Add(_scale); 
     group.Children.Add(_skew); 
     group.Children.Add(_rotate); 
     group.Children.Add(_translate); 

     return group; 
    } 
}
