Caution

Callers should use the CrispImage control for properly scaled images. Additionally, in some cases this markup extension can cause crashes.

MarkupExtension class that can be used to declare image sources in xaml and have the image pre-scaled for High DPI at zoom levels higher than 200%, using NearestNeighbor up to the largest multiple of 100%.

A common usage pattern can look like this: or <Image.LayoutTransform></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

Remarks

A common usage pattern can look like this:

<Image Source="{imaging:DpiPrescaledImage resources/MyImage.png}" Width="16" Height="16" />

<Image Source="{imaging:DpiPrescaledImage resources/MyImage.png}" Stretch="None">  
    <Image.LayoutTransform>  
    <ScaleTransform ScaleX="{x:Static utilities:DpiHelper.Default.PreScaledImageLayoutTransformScaleX}" ScaleY="{x:Static utilities:DpiHelper.Default.PreScaledImageLayoutTransformScaleY}" />  
    </Image.LayoutTransform>  
</Image>
