<hr><a name="_details"></a><h2>Detailed Description</h2>
A layer of an <a class="el" href="class_ipe_page.html">IpePage</a>.
<p>
Each object on an <a class="el" href="class_ipe_page.html">IpePage</a> belongs to one of the layers of the page. Layers are orthogonal to the back-to-front ordering of objects, so a "layer" is just another attribute of the object.<p>
Layers have several attributes:<p>
<ul>
<li>They may be editable or locked. Objects in a locked layer cannot be selected, and a locked layer cannot be made active in the Ipe UI. This more or less means that the contents of such a layer cannot be modified---but that's a consequence of the UI, Ipelib contains no special handling of locked layers.</li></ul>
<p>
<ul>
<li>A layer may be dimmed (on the screen - no dimming appears on PDF or Postscript output).</li></ul>
<p>
<ul>
<li>A layer may have snapping on or off---objects will behave magnetically only if their layer has snapping on.</li></ul>
<p>
The PDF output generated for an <a class="el" href="class_ipe_page.html">IpePage</a> depends on its <em>views</em>. Each view may list a number of layers to be displayed at that stage. Multiple <em>views</em> may show different subsets of layers.
