Remarks

A common usage pattern can look like this:

<imaging:DpiPrescaleImageSourceConverter x:Key="DpiPrescaleImageSourceConverter" />  
. . .  
<Image Source="{Binding Path=SelectedItem.Image, Converter={StaticResource DpiPrescaleImageSourceConverter}}" Width="16" Height="16" />  

or

<Image Source="{Binding Path=SelectedItem.Image, Converter={StaticResource DpiPrescaleImageSourceConverter}}" Stretch="None">  
    <Image.LayoutTransform>  
    <ScaleTransform ScaleX="{x:Static utilities:DpiHelper.Default.PreScaledImageLayoutTransformScaleX}" ScaleY="{x:Static utilities:DpiHelper.Default.PreScaledImageLayoutTransformScaleY}" />  
    </Image.LayoutTransform>  
</Image>  

Note that when using image pre-scaling, either the original image size has to be specified, or a reverse layout transform has to be applied to the result, to maintain the desired original image size.
