<Window x:Class="MainWindow"



    Title="MainWindow" Height="350" Width="525">

        Width="433" Margin="20">

        <Canvas Height="200" Width="200">



                    <ScaleTransform ScaleY="-1" />



            <Rectangle Canvas.Top="-146" Canvas.Left="-55" Width="192"

                Height="103" Stroke="darkgreen" StrokeThickness="3">


                    <ImageBrush ImageSource="/WpfApplication65;component/Images/file4.jpg" />




                ScaleX="{Binding ElementName=slider,Path=Value}"

                ScaleY="{Binding ElementName=slider,Path=Value}" />



            <Slider Name="slider" Minimum="0" Maximum="3" TickPlacement="BottomRight" TickFrequency="0.2"

      IsSnapToTickEnabled="True" Canvas.Left="-63" Canvas.Top="-243" Height="22" Width="222" Value="1" />
