Ok,

So I've tried to make an application which relies on images being scaled by an individual factor. These images are then able to be turned over, but the use of an animation working on the ProjectionPlane rotation.

The problem comes around when an image is both scaled and rotated. For some reason it starts bluring, where a non scaled image doesn't blur.

Also, if you look at the example image below (top is scaled and rotated, bottom is rotated) the projection of the top one doesn't even seem right. Its too horizontal.

This this the code for the test app:

<UserControl x:Class="SilverlightApplication1.Page"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Width="400" Height="300">
    <Canvas x:Name="LayoutRoot" Background="White">

            <Border Canvas.Top="25" Canvas.Left="50">

                <Border.RenderTransform>
                    <TransformGroup>
                        <ScaleTransform ScaleX="3" ScaleY="3" />
                    </TransformGroup>
                </Border.RenderTransform>

                <Border.Projection>
                    <PlaneProjection RotationY="45"/>
                </Border.Projection>

                <Image Source="bw-test-pattern.jpg" Width="50" Height="40"/>
            </Border>

            <Border Canvas.Top="150" Canvas.Left="50">
                <Border.RenderTransform>
                    <TransformGroup>
                        <ScaleTransform ScaleX="1" ScaleY="1" />
                    </TransformGroup>
                </Border.RenderTransform>

                <Border.Projection>
                    <PlaneProjection RotationY="45"/>
                </Border.Projection>

                <Image Source="bw-test-pattern.jpg" Width="150" Height="120"/>
            </Border>

    </Canvas>
</UserControl>

So if anyone could possible shed any light on why this may be happening, I'd very much appreciate it. Suggestions also welcome! :)
