CanvasRenderingContext2D.miterLimit
The CanvasRenderingContext2D.miterLimit
property of the Canvas 2D API sets the miter limit ratio in space units. When getting, it returns the current value (10.0
by default). When setting, zero, negative, Infinity
and NaN
values are ignored; otherwise the current value is set to the new value.

WebKit/Blink-specific notes
- In WebKit- and Blink-based Browsers, a non-standard and deprecated method
ctx.setMiterLimit()
is implemented besides this property.
Gecko-specific notes
- Starting Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1), setting
miterLimit
to a negative value no longer throws an exception; instead, it properly ignores non-positive values.
