title: Blending render targets
body: <p>I have two render targets that i draw to, and i want to combine (blend) them, easiest by alpha value maybe, to one picture using the gpu via directx. One target is the background, the other the data i want to plot.</p>
  
  <p>I can't just plot the data over the background, because i don't want to store the data between new draws. That works well for other use cases. But now not anymore. So I append the data to the one target and it would be nice to just blend this two targets efficiently.</p>
  
  <p>I'm a bit lost in the documentation and can't really find an example to relate. I'm using sharpdx</p>
  
  <p>Any help appreciated, thanks</p>
