#802 – Transforms Do Not Affect an Element’s Margins

When you apply a 2D transform to a user interface element, the transform impacts only the element and everything inside of the element.  It therefore does not change the element’s margins.

In the example below, we have a Label element that has a margin of 5 separating it from its parent Border.  Notice that when we scale the second instance of the Label, it still retains the same margin.

    <StackPanel>
        <Border BorderBrush="Black" BorderThickness="3" HorizontalAlignment="Center">
            <Label Background="LightCoral" Content="Scale Me" Margin="5"/>
        </Border>
        <Border BorderBrush="Black" BorderThickness="3" HorizontalAlignment="Center">
            <Label Background="LightCoral" Content="Scale Me" Margin="5">
                <Label.LayoutTransform>
                    <ScaleTransform ScaleX="1.5"/>
                </Label.LayoutTransform>
            </Label>
        </Border>
    </StackPanel>
