最近在研究canvas，简单的用canvas绘制了一下卡通人物--海绵宝宝。
图片如下：
代码如下：
<!DOCTYPE html>

<meta charset="utf-8" />
<title>canvas海绵宝宝</title>

<body>
<canvas id="canvas" width="1000" height="700" style="background: #01539f;"></canvas>
</body>
<script>
var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
