how to a zoom option to my wpf app?

I'm working on wpf application , the application draws the countours on an existing image and i want to add a button which give me the hand to zoom the image to see the countours

i added a button and a fonction on .cs but it doesn't work

here's the code cs 

namespace AnimationTest
{
public partial class MainWindow: Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, RoutedEventArgs e)
    {
        DoubleAnimation da = new DoubleAnimation();
        da.From = 0;
        da.To = 1000;
        da.Duration = new Duration(TimeSpan.FromSeconds(1));
        image1.BeginAnimation(ScaleTransform.CenterXProperty, da);

    }
}

}

and XAML Code 

<Window x:Class="AnimationTest.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="720" Width="1280">
<Grid>
    <Image Height="681" HorizontalAlignment="Left" Name="image1" Stretch="None" VerticalAlignment="Top" Width="1258" Source="/AnimationTest;component/Images/world.jpg" />
    <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="1171,12,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />

This has no sens image1.BeginAnimation(ScaleTransform.CenterXProperty, da); You start an animation on an image of a property that don't belong to Image control. You should create a scale transform, set it on the image and then start the animation on scale transform object, not the image.
