Getting pixels from render?

Hi guys!

I'm looking at the BABYLON.Tools.CreateScreenshot() function, and I'm trying to use bits of that code to create an image (encoded in base64) from the babylon canvas.
I do this:


  this.canvas = document.createElement('canvas');
  this.canvas.width = Game.canvas.width;
  this.canvas.height = Game.canvas.height;
  this.ctx = this.canvas.getContext("2d");
  this.ctx.drawImage(Game.engine.getRenderingCanvas(), 0, 0, Game.canvas.width, Game.canvas.height);
  console.log(this.ctx.getImageData(0, 0, Game.canvas.width, Game.canvas.height));
  $("#render").attr('src', this.canvas.toDataURL("image/png"))

And all it does is create an empty image, and the data is just an array full of 0's! AHHHHHH

Why is this?

Ahhhhhhhgggg today's my one day off I can't get this working, which is the main point of the program! ;_;

Basically, I want to rebuild the screenshot tool, but it seems not to work.

How can I hijack it without it saving the image?

EDIT: Ok, at last I figured it out. I simply copied the functions BABYLON.Tools.DumpFramebuffer() and  BABYLON.Tools.CreateScreenshot (which for some reason is "CreateScreenshotUsingRenderTarget" in github, hence all the confusion) and renamed them to my liking. VERY UGLY, but it works :)
