ScaleTransform的图像

Question

我想所以我使用ScaleTransform，如下图所示由20增加图像的大小..但下面的代码没有做任何大规模变换分析..任何帮助，将不胜感激......

<Grid>
    <Canvas>
    <Canvas Height="50" Width="50" Canvas.Top="10" Canvas.Left="100"
            Visibility="Visible">
        <Image Name="Img" Source="Help.PNG" Canvas.Left="0" Canvas.Top="0">
        </Image>
    </Canvas>
    <Button Canvas.Left="100" Canvas.Top="100" Height="42.5" Name="button3"
            Width="100" Visibility="Visible">
        <Button.Triggers>
            <EventTrigger RoutedEvent="Button.Click">
                <BeginStoryboard>
                    <Storyboard Name="MoveBox">
                        <DoubleAnimation Storyboard.TargetName="Img"
      Storyboard.TargetProperty="(Image.RenderTransform).(ScaleTransform.ScaleX)"
      From="1" To="20" BeginTime="0:0:3.75" Duration="0:0:1.25" />
                        <DoubleAnimation Storyboard.TargetName="Img"
      Storyboard.TargetProperty="(Image.RenderTransform).(ScaleTransform.ScaleY)"
      From="1" To="20" BeginTime="0:0:3.75" Duration="0:0:1.25" />
                    </Storyboard>
                </BeginStoryboard>
            </EventTrigger>
        </Button.Triggers>
    </Button>
    </Canvas>
</Grid>

你试过在图像上设置<RenderTransform>？是这样的：

    <Image Name="Img" Source="Help.PNG" Canvas.Left="0" Canvas.Top="0">
        <Image.RenderTransform>
            <ScaleTransform x:Name="scale" ScaleX="1" ScaleY="1"
                            CenterX="0.5" CenterY="0.5" />
        </Image.RenderTransform>
    </Image>

此初始化的RenderTransform，这样就可以指从其他地方给它。

我已经与Silverlight来做到这一点。
