canvas里边可以放.gif动态图片吗?

想在canvas里边放.gif图片,但是用
document.getElementById("tulip").onload=function(){
var c=document.getElementById("myCanvas");
var ctx=c.getContext("2d");
var img=document.getElementById("tulip");
ctx.drawImage(img,0,0);
};
图片成静态了,不动了,大神们请问canvas里可以加载动态图片吗,有什么好办法吗?

没有,自己拆分gif为不同图片来给canvas加载
