//画线

cxt.moveTo(10,10);

cxt.lineTo(150,50);

cxt.lineTo(10,50);

cxt.stroke();

//画圆

cxt.fillStyle="#FF0000";

cxt.beginPath();

cxt.arc(70,18,15,0,Math.PI*2,true);

cxt.closePath();

cxt.fill();

//渲染

var grd=cxt.createLinearGradient(0,0,175,50);

grd.addColorStop(0,"#FF0000");

grd.addColorStop(1,"#00FF00");

cxt.fillStyle=grd;

cxt.fillRect(0,0,175,50);
