HTML canvas miterLimitProperty
Example
Draw a line with a maximum miter length of 5:
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();
var ctx=c.getContext("2d");
ctx.lineWidth=10;
ctx.lineJoin="miter";
ctx.miterLimit=5;

Definition and Usage
The miterLimit property sets or returns the maximum miter length.
The miter length refers to the distance between the inner corner and the outer corner where two lines meet.

Tip:The miterLimit is only effective when the lineJoin property is "miter".
The smaller the angle of the corner, the larger the miter length will be.
To avoid the miter lengthbeing too long, we can use the miterLimit property.
If the miter length exceeds the value of miterLimit, the corner will be displayed in the "bevel" type of lineJoin (Fig 3):

| Default value: | 10 |
|---|---|
| JavaScript syntax: | context.miterLimit=number; |
Property Value
