html5的canvas是很强大的，今天也是温习了一下之前的基础知识，然后学着做了一个简单的小案例。虽然在这一块几乎空白，但还是乐于尝试......
效果如下：
代码如下：
<div class="doraemon">
<canvas id="face" width="600" height="1500">您的浏览器不支持canvas</canvas>
</div>
<script>
var face = document.getElementById('face').getContext("2d");
face.arc(252,252,250,0,360*Math.PI/180);
face.fillStyle = '#07beea'; //设置填充颜色
face.fill(); //填充
face.lineWidth = 2; //轮廓线宽度
face.strokeStyle = '#333'; //轮廓线颜色
face.stroke(); //画轮廓线 face.beginPath(); //重置当前绘画路径
face.moveTo(160,450); //画笔移动到起始点
face.bezierCurveTo(0,400,0,110,210,115); //三次贝塞尔曲线（左边）
face.lineTo(290,115);
face.bezierCurveTo(500,110,500,400,340,450);
face.bezierCurveTo(280,470,220,470,160,450);
face.fillStyle = '#fff';
face.fill();
face.stroke(); //画出边框 face.beginPath(); //重置当前绘画路径 用于画眼睛和鼻子
face.moveTo(150,150);
face.lineTo(150,100); //左眼左竖线
face.bezierCurveTo(160,50,240,50,250,100); //左眼下面
face.lineTo(250,150); //左眼右竖线
face.bezierCurveTo(240,200,160,200,150,150); //左眼上面
face.moveTo(250,150);
face.lineTo(250,100); //右眼左竖线
face.bezierCurveTo(260,50,340,50,350,100); //右眼上面
face.lineTo(350,150); //右眼右竖线
face.bezierCurveTo(340,200,260,200,250,150); //右眼下面
face.fillStyle = '#fff';
face.fill();
face.stroke(); face.beginPath();
face.arc(225,155,10,0,360*Math.PI/180); //眼珠
face.arc(275,155,10,0,360*Math.PI/180);
face.fillStyle = '#333';
face.fill(); face.beginPath(); //鼻子
face.arc(250,197,25,0,360*Math.PI/180);
face.fillStyle = '#c93e00';
face.fill();
face.stroke(); face.beginPath();
face.arc(260,190,10,0,360*Math.PI/180);
var grd = face.createRadialGradient(260,190,2,260,190,10); //设置内外圆原点和半径
grd.addColorStop(0,'#fff');
grd.addColorStop(1,'#c93e00');
face.fillStyle = grd;
face.fill(); //嘴巴
face.beginPath();
face.moveTo(250,222);
face.lineTo(250,395);
face.moveTo(100,320);
face.bezierCurveTo(180,420,320,420,400,320);
face.lineWidth = 3;
face.stroke(); //胡须
face.beginPath();
face.moveTo(80,200);
face.lineTo(180,220);
face.moveTo(80,245);
face.lineTo(180,245);
face.moveTo(80,290);
face.lineTo(180,270); face.moveTo(320,220);
face.lineTo(420,200);
face.moveTo(320,245);
face.lineTo(420,245);
face.moveTo(320,270);
face.lineTo(420,290);
face.stroke(); </script>
