<p>The <code>Geometry.jsm</code> JavaScript code module provides routines for performing common geometry operations on points and rectangles. It exports two classes: <code>Point</code> and <code>Rect</code>.</p>
<p>To use these routines, you first need to import the code module into your JavaScript scope:</p>
<pre class="eval"><span class="nowiki">Components.utils.import("resource://gre/modules/Geometry.jsm");</span>
</pre>
<p>Once you've imported the module, you can then use the <a href="/en/JavaScript_code_modules/Geometry.jsm/Point" title="en/JavaScript code modules/Geometry.jsm/Point"><code>Point</code></a> and <a href="/en/JavaScript_code_modules/Geometry.jsm/Rect" title="https://developer.mozilla.org/en/JavaScript_code_modules/Geometry.jsm/Rect"><code>Rect</code></a> classes.</p>
<div class="note"><strong>Note:</strong> Although this module is usable from mobile, and is present in Firefox 4, it's currently not used in Firefox 4 and attempting to use it may produce unreliable results there.</div>
