Html2canvas creates a slightly blurry image

Question

I use the basic html2canvas functionality with a gif image inside a div. When I convert a div to canvas, the image plays slightly. Is there a fix for this or some parameter that I have to set?

html2canvas($("#panel-container"), {  
  proxy: "https://html2canvas.appspot.com/query",
  onrendered: function(canvas) {
  document.body.appendChild(canvas);
}
});

html2canvas();
