这最终可能是一个非常愚蠢的问题，所以如果这很简单，请原谅我 - 我对 Silverlight 很陌生 :)

我想做的是将下面的 Image.RenderTransform 示例添加到我自己的项目中，但我的图像控件位于滚动查看器中，每当我尝试添加它时，我都会收到消息：

“在“图像”类型中找不到可附加属性“RenderTransform”

<Image MaxHeight="220" MaxWidth="200" Name="image1" Stretch="Uniform" Source="/FunWithMouseWheel;component/Images/sl4bloglogo.png" MouseWheel="image1_MouseWheel" Margin="531,346,124,199">
    <Image.RenderTransform>
        <ScaleTransform x:Name="imageScale"></ScaleTransform>
    </Image.RenderTransform>
</Image>

我的 Xaml 文件：

<UserControl x:Class=Image_Viewer.MainPage"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        <Button Content="Rotate Left" Height="35" HorizontalAlignment="Left" Margin="132,10,0,0" Name="btnRotateLeft" VerticalAlignment="Top" Width="115" />

        <ScrollViewer Grid.ColumnSpan="2" Height="520" HorizontalAlignment="Left" Margin="37,60,0,0" Name="scrollViewer" VerticalAlignment="Top" Width="840" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
            <ScrollViewer.Background>
                <LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5">
                    <GradientStop Color="#FF89D2FC" Offset="0" />
                    <GradientStop Color="#00009AFF" Offset="1" />
                </LinearGradientBrush>
            </ScrollViewer.Background>
            <Image Height="465" Name="imgData" Stretch="Uniform" Width="767" MouseLeftButtonDown="imgData_MouseLeftButtonDown" MouseWheel="imgData_MouseWheel" />

        <Image.RenderTransform></Image.RenderTransform> <----- causes the error
        </ScrollViewer>
        <Slider Height="248" HorizontalAlignment="Left" Margin="222,60,0,0" Name="slider" VerticalAlignment="Top" Width="39" Orientation="Vertical" Grid.Column="1" />
    </Grid>
</UserControl>

感谢您的帮助！

修复它 - 最后很简单！

问题是图像标签在该行中被关闭：

 <Image Height="465" Name="imgData" Stretch="Uniform" Width="767" MouseLeftButtonDown="imgData_MouseLeftButtonDown" MouseWheel="imgData_MouseWheel" />

所以我只是删除了结束标记 / 并插入了 Image.RenderTransform 标记和一个额外的结束标记：

    <Image Height="465" Name="imgData" Stretch="Uniform" Width="767" MouseLeftButtonDown="imgData_MouseLeftButtonDown" MouseWheel="imgData_MouseWheel">
        <Image.RenderTransform>
            <RotateTransform Angle="0" />
        </Image.RenderTransform>
    </Image>
