Overlay two images using WriteableBitmap

I have got two images, say png and jpeg and I need to overlay them. In WPF it can be done by DrawingGroup (unavailable in SL). I guess it mig开发者_JAVA技巧ht be done with WriteableBitmap instead. Do you have any idea how to do that?

Thanks in advance!

Cheers

Just use a Grid instead:-

 <Grid>
    <Image Source="MyPic1.png" VerticalAlignment="Top" HorizontalAlignment="Left" />
    <Image Source="MyPic2.jpg" VerticalAlignment="Top" HorizontalAlignment="Left" />
 </Grid>
