Width="640" Height="480">

<Grid x:Name="LayoutRoot">
    <Image Margin="104,50,75,99" Source="barkship.jpg"/>

It's very possible, if you know the x, y, width and height of the areas that you want to highlight already you can place all of the controls in to a canvas.

You can set the properties on the rectangles in code behind like this:

Rectangle rectangle = new Rectangle();
rectangle.SetValue(Canvas.LeftProperty, 10);
rectangle.SetValue(Canvas.TopProperty, 10);
rectangle.Width = 1000;
rectangle.Height = 50;
rectangle.Fill = new SolidColorBrush() { Color = Colors.Red, Opacity = 0.75f };

canvas.Children.Add(rectangle);

and if you want to add them in xaml you can like this.

<Canvas>
    <Image Source="..."/>
    <Rectangle Canvas.Left="10" Canvas.Top="10" Width="1000" Height="50">
        <Rectangle.Fill>
           <SolidColorBrush Color="Red" Opacity="0.75"/>
        </Rectangle.Fill>
    </Rectangle>                        
</Canvas>
