I’ve got a Grid with some scale transform applied; the Grid contains an image:

<Grid Background="Black">
    <Grid.LayoutTransform>
        <ScaleTransform ScaleX="5.7" ScaleY="3.7"/>
    </Grid.LayoutTransform>
    <Image Source="rw.bmp" VerticalAlignment="Top"/>
</Grid>

The image is 2 by 1 pixels, one pixel red and one white:

original image

stretched actual image

You can see that the actual rendered image is somehow kind of smoothed before stretch, instead of being smoothed after stretch.
Is there a way to get the image as in the expected example?

Edit: tried different values of RenderOptions.BitmapScalingMode. The closest to what I need is “NearestNeighbor”, which gives the following:
