title: Javascript Get Facebook Profile Image Pixel Data
body: <p>I need to get the pixel data from a random user's Facebook profile image so I can pass it through Emscripten to our C++ app. That is, I need the RGB values of each pixel. I've tried lots of different ways, using the Javascript FBSDK, graph calls, downloading images, and trying to draw to a canvas I've created but I run into all sorts of issues, e.g. cross domain problems. I don't need it to be rendered to a visible canvas, I just need toe data to pass back to our app.</p>
  
  <p>Is there a simple way please ?</p>
