html - How to play gif inside canvas in HTML5

Question

I want to play animated GIF file inside a HTML Canvas. I have used the code below but it is not working.

What is wrong with the code?

var drawingCanvas = document.getElementById('myDrawingCanvas');
if(drawingCanvas.getContext) 
{
    var context = drawingCanvas.getContext('2d');
    var imgObj = new Image();

    imgObj.onload = function () 
    {       
        context.drawImage(imgObj, 0, 0, 1024, 600);
    }
    imgObj.src='HTML Images/Spell Bee/images/mainscreen.gif';
}

Answer 1

You cannot as canvas doesn't provide any methods to deal with animated gifs. You should split gif into single frames then create a spritesheet and animate it copying current frame.
