<hr><a name="_details"></a><h2>Detailed Description</h2>
Repository of attribute values.
<p>
Ipe documents can use symbolic attributes, such as 'normal', 'fat', or 'thin' for line thickness, or 'red', 'navy', 'turquoise' for color, as well as absolute attributes such as (0.5,0.5,0.5) for medium gray. To avoid storing these very common values hundreds of times, <a class="el" href="class_ipe_repository.html">IpeRepository</a> keeps a repository of all the non-scalar attribute values in the document. Inside IpeObject's attributes are represented as integer indices into the repository.<p>
There are currently the following symbolic attributes with values stored in the repository.<ul>
<li>Color</li><li>Line style (dash pattern)</li><li>Font size</li><li>Text style (Latex style)</li></ul>
<p>
The following attributes can be symbolic, but if they are absolute then the scalar value is stored inside the <a class="el" href="class_ipe_attribute.html">IpeAttribute</a> (not in the repository).<ul>
<li>Mark size</li><li>Arrow size</li><li>Grid size</li><li>Angle size (for angular snap)</li><li>Line width</li></ul>
<p>
Finally, line join, line cap, and the fill rule cannot be symbolic. They can be null, or have an absolute value stored inside the attribute.
