HTML5 Canvas 路径
- 子路径是连接两点的连接。
- 起点和结束点是连接子路径。
- 某些预定决定方法是在Create Path：Lineto()，Arcto()，Quadraticto()和Beziercurveto()中使用的
- withpath()方法启动一个新路径。
HTML5 Canvas 路径语法
context.beginPath();
HTML5 Canvas 路径示例
<!DOCTYPE HTML>
<html>
<head>
<style>
body
{
margin: 0px;
padding: 0px;
}
#myCanvas
{
border: 1px solid #9C9898;
}
</style>
<script>
window.onload = function ()
{
var canvas = document.getElementById("myCanvas");
var context = canvas.getContext("2d");
context.beginPath();
context.moveTo(100, 20);
//line 1
context.lineTo(200, 160);
//quadratic curve
context.quadraticCurveTo(230, 200, 250, 120);
//bezier curve
context.bezierCurveTo(290, -40, 300, 200, 400, 150);
//line 2
context.lineTo(500, 90);
context.lineWidth = 5;
context.strokeStyle = "blue";
context.stroke();
};
</script>
</head>
<body>
<canvas id="myCanvas" width="578" height="200"></canvas>
</body>
</html>
