How use Pixi with filter Pixilate?

[htmllab]

Hi all! 

I make the first steps with the Pixi and I need help.

I want to take a picture from canvas and applied to the image Pixelate filter (as here http://www.goodboydigital.com/pixijs/examples/15/indexAll.html).

pondFloorTexture = PIXI.Texture.fromImage("img/image.jpg");//work!

pondFloorTexture = PIXI.Texture.fromCanvas(document.querySelector("#mycanvas"));//not work(

No errors, but it does not work

Oops!  I'm sorry. If you do not only paint the background of the canvas, and draw something - Pixi will draw all. If only the background is painted - it is perceived transparent

...
var can = document.querySelector("#mycanvas");
      if (can.getContext) {
        var ctx3 = can.getContext("2d");

        ctx3.fillStyle = "rgb(200,0,0)";
        ctx3.fillRect (10, 10, 50, 50);

        ctx3.fillStyle = "rgba(0, 0, 200, 0.5)";
        ctx3.fillRect (30, 30, 50, 50);
}
...
pondFloorTexture = PIXI.Texture.fromCanvas(can);//all work

The next step is to apply the filter Pixelate
