HTML canvas miterLimit 属性

❮ Canvas 对象

实例

绘制最大斜接长度为 5 的线:

YourbrowserdoesnotsupporttheHTML5canvastag.

JavaScript:

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
ctx.lineWidth = 10;
ctx.lineJoin = "miter";
ctx.miterLimit = 5;
ctx.moveTo(20, 20);
ctx.lineTo(50, 27);
ctx.lineTo(20, 34);
ctx.stroke();

浏览器支持

表中的数字表示支持该属性的第一个浏览器版本。

属性
miterLimit 4.0 9.0 3.6 4.0 10.1

定义和用法

miterLimit 属性设置或返回最大斜接长度。

斜接长度是两条线相交的内角和外角之间的距离。

斜接极限图1

提示: 只有当 lineJoin 属性为"miter"时,miterLimit 属性才有效。

随着角的角度变小,斜接长度变大。

为了防止斜接长度过长,我们可以使用 miterLimit 属性。

如果斜接长度超过miterLimit值,角将显示为lineJoin type "bevel"(图3):

Miter Limit figure 2
默认值: 10
JavaScript 语法: context.miterLimit = number;

属性值

描述 Play it
number 一个正数,指定最大斜接长度。 如果当前斜接长度超过 miterLimit,角将显示为 lineJoin "bevel" Play it »
