## clip()
裁剪路徑的作用是**遮罩**。只顯示裁剪路徑內的區域，裁剪路徑外的區域會被隱藏,

實例
```
function draw(){
    var canvas = document.getElementById('tutorial1');
    if (!canvas.getContext) return;
    var ctx = canvas.getContext("2d");
 
    ctx.beginPath();
    ctx.arc(20,20, 100, 0, Math.PI * 2);
    ctx.clip();
 
    ctx.fillStyle = "pink";
    ctx.fillRect(20, 20, 100,100);
}
```
