WPF实现图片倒影

比较简单，主要用到ScaleTransfrom类和VisualBrush类

<Window x:Class="实现图片倒影的方式.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid HorizontalAlignment="Center">
        <Grid.RowDefinitions>
            <RowDefinition/>
            <RowDefinition/>
        </Grid.RowDefinitions>


        <Image Grid.Row="0" Name="image" Source="C:Users天天开心Pictures58c3cbef76094b3605d27002a5cc7cd98c109d0f.jpg" Margin="3"></Image>
        <Rectangle Grid.Row="1" Margin="3">
            <Rectangle.Fill>
                <VisualBrush Visual="{Binding ElementName=image}">
                    <VisualBrush.RelativeTransform>
                        <ScaleTransform ScaleY="-1" CenterY=".5"></ScaleTransform>
                    </VisualBrush.RelativeTransform>
                </VisualBrush>
            </Rectangle.Fill>
            
            
            <Rectangle.OpacityMask>
                <LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
                    <GradientStop Color="Black" Offset="0"></GradientStop>
                    <GradientStop Color="Transparent" Offset=".6"></GradientStop>
                </LinearGradientBrush>
            </Rectangle.OpacityMask>
            
        </Rectangle>
        
    </Grid>
</Window>
