Caution
Use Microsoft.VisualStudio.Imaging.CrispImage instead.
Converts an ImageSource into another ImageSource. If the input image ia a BitmapSource, the transformed BitmapSource has its halo color mapped to the given background color and is conditionally rendered as disabled. The resultant image is then pre-scaled on High DPI to the largest zoom multiple of 100% smaller than the DPI zoom.This converter chains the behavior of ThemedImageSourceConverter and DpiPrescaleImageSourceConverter.

Remarks
A common usage pattern can look like this:
<imaging:DpiPrescaleThemedImageSourceConverter x:Key="DpiPrescaleThemedImageSourceConverter" />
<Image UseLayoutRounding="True" SnapsToDevicePixels="True" Width="16" Height="16">
<Image.Source>
<MultiBinding Converter="{StaticResource DpiPrescaleThemedImageSourceConverter}">
<Binding Path="Icon" />
<Binding Path="(imaging:ImageThemingUtilities.ImageBackgroundColor)" RelativeSource="{RelativeSource Self}" />
<Binding Source="{x:Static utilities:Boxes.BooleanTrue}" />
</MultiBinding>
</Image.Source>
</Image>
Where the image dimensions aren't known at compile time, instead of specifying exact Width/Height properties, a layout transform can be specified on the image like this:
<Image.LayoutTransform>
/// <ScaleTransform ScaleX="{x:Static util:DpiHelper.Default.PreScaledImageLayoutTransformScaleX}" ScaleY="{x:Static util:DpiHelper.Default.PreScaledImageLayoutTransformScaleY}" />
/// </Image.LayoutTransform>
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
