<p>Свойство <strong>CanvasRenderingContext2D.miterLimit</strong> устанавливает/возвращает максимальную длину среза.</p>

<p>Длина среза это расстояние между внутренним и внешнем углом, образованным пересечением двух линий.</p>

<ul>
 <li>In WebKit- and Blink-based Browsers, a non-standard and deprecated method <code>ctx.setMiterLimit()</code> is implemented in addition to this property.</li>
</ul>

<h3 id="Gecko-specific_notes">Gecko-specific notes</h3>

<ul>
 <li>Starting Gecko 2.0 {{geckoRelease("2.0")}}, setting <code>miterLimit</code> to a negative value no longer throws an exception; instead, it properly ignores non-positive values.</li>
