Description
The miterLimit property sets or returns the maximum miter length.
The miter length is the distance between the inner corner and the outer corner where two lines meet.

Tip: The miterLimit property works only if the lineJoin attribute is "miter".
The miter length grows bigger as the angle of the corner gets smaller.
To prevent the miter length from being too long, we can use the miterLimit property.
If the miter length exceeds the miterLimit value, the corner will be displayed as lineJoin type "bevel" (Fig 3):

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