Var image=new Image();
image.src=” http://img4.duitang.com/uploads/item/201406/25/20140625182321_4MTau.thumb.700_0.jpeg”;
image.onload=function(){}
Context.drawImage(image,x,y);
Context.drawImage(image,x,y,w,h);
Context.drawIamge(image,sx,sy,sw,sh,dx,dy,dw,dh);
圖片平鋪
Var pat= context.createPattern(image,”repeat”);
Context.fillStyle=pat;
Context.fillRect(0,0,400,300);

Context.clip();
