使用HTML5画布绘制贝塞尔曲线
是的，请使用HTMLcanvasbezierCurveTo()方法在HTML5中绘制Bezier曲线。
示例
您可以尝试运行以下代码以使用画布绘制贝塞尔曲线：
<!DOCTYPE HTML>
<html>
<head>
<style>
#test {
width: 100px;
height:100px;
margin: 0px auto;
}
</style>
<script>
function drawShape(){
//使用DOM获取canvas元素
var canvas = document.getElementById('mycanvas');
//确保不支持画布时不执行
if (canvas.getContext){
//使用getContext使用画布进行绘制
var ctx = canvas.getContext('2d');
ctx.beginPath();
ctx.moveTo(75,40);
ctx.bezierCurveTo(75,37,70,25,50,25);
ctx.bezierCurveTo(20,25,20,62.5,20,62.5);
ctx.bezierCurveTo(20,80,40,102,75,120);
ctx.bezierCurveTo(110,102,130,80,130,62.5);
ctx.bezierCurveTo(130,62.5,130,25,100,25);
ctx.bezierCurveTo(85,25,75,37,75,40);
ctx.fill();
} else {
alert('You need Safari or Firefox 1.5+ to see this demo.');
}
}
</script>
</head>
<body id = "test" onload = "drawShape();">
<canvas id = "mycanvas"></canvas>
</body>
</html>
