I can find lots of threads and blogs which related to add watermark to image, but all of them are using GDI+, in winrt, it couldn't work. Anyone know how to add watermark to image in windows 8 app?
This gets the job done visually:
<Grid>
<Image Source="{Binding MyImage}" />
<Image Source="{Binding MyWatermark}" />
</Grid>
