XAML code

<Window x:Class="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">

    <Border BorderBrush="Black" BorderThickness="1" Height="208"

        Width="433" Margin="20">

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

            <Canvas.RenderTransform>

                <TransformGroup>

                    <ScaleTransform ScaleY="-1" />

                </TransformGroup>

            </Canvas.RenderTransform>

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

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

                <Rectangle.Fill>

                    <ImageBrush ImageSource="/WpfApplication17;component/Images/flowers-image.jpg" />

                </Rectangle.Fill>

                <Rectangle.RenderTransform>

                    <ScaleTransform

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

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

                </Rectangle.RenderTransform>

            </Rectangle>

            <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" />

        </Canvas>

    </Border>

    </Window>

Now run the application. The form looks like this.
