CanvasRenderingContext2D.miterLimit

The CanvasRenderingContext2D.miterLimit property of the Canvas 2D API sets the miter limit ratio.

Note: For more info about miters, see Applying styles and color in the Canvas tutorial.

Value

A number specifying the miter limit ratio, in coordinate space units. Zero, negative, Infinity, and NaN values are ignored. The default value is 10.0.

Examples

Using the `miterLimit` property

See the chapter Applying styles and color in the Canvas tutorial for more information.

<canvas id="canvas" width="400" height="200" class="playable-canvas"></canvas>
<div class="playable-buttons">
  <input id="edit" type="button" value="Edit" />
  <input id="reset" type="button" value="Reset" />
</div>
<textarea id="code" class="playable-code">
ctx.beginPath();
ctx.moveTo(0,0);
ctx.lineWidth = 15;
ctx.lineTo(100, 100);
ctx.stroke();</textarea>

var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
var textarea = document.getElementById("code");
var reset = document.getElementById("reset");
var edit = document.getElementById("edit");
var code = textarea.value;

function drawCanvas() {
  ctx.clearRect(0, 0, canvas.width, canvas.height);
  eval(textarea.value);
}

reset.addEventListener("click", function() {
  textarea.value = code;
  drawCanvas();
});

edit.addEventListener("click", function() {
  textarea.focus();
})

textarea.addEventListener("input", drawCanvas);
window.addEventListener("load", drawCanvas);

WebKit/Blink-specific notes

In WebKit- and Blink-based Browsers, a non-standard and deprecated method ctx.setMiterLimit() is implemented in addition to 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.
