I think the key part in the question is here:<br>
<p class="MsoNormal"><span lang="EN-US">" and the center point of the symbol is no longer inside the map window".</span></p>
To my experience a symbol doesn't get drawn at all when the point which is symbolized is outside the requested extent (WMS mode at least).<br>
<br>
To solve that I created the mentioned pull request.<br>
<br>
Or do I miss something?<br>

<div>Hi Patrick,</div>
<div><br>
</div>
<div>i've submitted a pull request for extending the map by a buffer and then clipping it, so that partial symbols on the edge get rendered as well (wms non tiled mode).</div>
<div><br>
</div>
<div>maybe you can build from sources and use this patch to solve your problem.</div>

<div dir="ltr">Hello Patrick,
<div><br>
</div>
<div>if you are using PostGIS as datasource, I would solve the problem by integrating a st_buffer in the DATA element itself ;) The added bonus is that you will get the attribute values from a GetFeatureInfo (if implemented) in the whole buffer zone.</div>
<div>If not, you can try to use tile mode, and add some metabuffer (<a href="http://mapserver.org/output/tile_mode.html" target="_blank">see mapserver doc</a>)</div>
