</div>
<p>Because the representation of Freestyle strokes and SVG path objects is fundamentally different, a one-on-one
translation between Freestyle and SVG is not possible. The main shortcoming of SVG compared to Freestyle is that
Freestyle defines style per-point, where SVG defines it per-path. This means that Freestyle can produce much more
complex results that are impossible to achieve in SVG.</p>
<p>There are extended options for the exporter,
located at the specific panels of the Freestyle renderer at the View Layers tab of the Properties editor.
Those options are located at the Freestyle Line Style SVG Export panel, at the bottom of the tab.</p>
<p>The properties (no modifiers applied) that can be exported are:</p>
<ul class="simple">
<li>Base color</li>
<li>Base alpha</li>
<li>Base thickness</li>
<li>Dashes</li>
</ul>
</div>
<div class="section" id="animations">
<h2>Animations<a class="headerlink" href="#animations" title="Permalink to this headline"></a></h2>
<p>The exporter supports the creation of SVG animations. When the Mode is set to Animation, all frames from a render –
one when rendering a frame (<kbd class="kbd docutils literal notranslate">F12</kbd>)
or all when rendering an animation (<kbd class="kbd docutils literal notranslate">Shift-F12</kbd>) – are saved into a single file.
Most modern browsers support the rendering of SVG animations.</p>

</div>
<div class="section" id="exporting-fills">
<h3>Exporting Fills<a class="headerlink" href="#exporting-fills" title="Permalink to this headline"></a></h3>
<p>Fills are colored areas extracted from a Freestyle render result. Specifically, they are defined by a combination of
the Contour and External Contour edge type, combined with some predicates. The fill result can be unexpected,
when the SVG renderer cannot correctly render the path that the exporter has generated.
This problem is extra apparent in animations.</p>
<div class="figure align-center" id="id4">
<img alt="../_images/render_freestyle_export-svg_pallet.svg" src="../_images/render_freestyle_export-svg_pallet.svg" /><p class="caption"><span class="caption-text">An example of a SVG result produced by the Freestyle SVG Exporter.
Model by <a class="reference external" href="https://github.com/xuv">Julien Deswaef</a>.</span></p>
</div>
<p>Fills support holes and layering. When using layers, the exporter tries to render objects with the same material as
the patch. The exporting of fills and especially the order in which they are layered is by no means perfect.
In most cases, these problems can be easily solved in Inkscape or a text editor.</p>
