<blockquote>Hi Michal,<br /> <br /> you could use a combination of st_xmin, st_ymin, st_xmax and st_ymax instead of st_extent. They will provide you with the same coordinates as st_extent but in a numeric data type.<br /> <br /> Hope that helps,<br /> <br /> Birgit.<br /> <br /> <br /> Am 05.12.2011 12:26, schrieb Micha³ Dro¿d¿:

<p>Hi List!</p>
<p>I am fresh Postgis user and have a problem with ST_EXTENT. I am using it to get data for map.zoomToExtent in openLayers.</p>
<p> </p>
<p>The problem is that zoomToExtens takes parameters as zoomToExtent(value,value,value,value)</p>
<p><a class="moz-txt-link-freetext" href="http://dev.openlayers.org/docs/files/OpenLayers/Map-js.html#OpenLayers.Map.zoomToExtent">http://dev.openlayers.org/docs/files/OpenLayers/Map-js.html#OpenLayers.Map.zoomToExtent</a></p>
<p> </p>
<p>from ST_EXTENT a receive WKT like this:</p>
<p>"BOX(2294970.88258299 6588308.80462897,2295532.89622321 6588616.7042758)"</p>
<p> </p>
<p>How to parse that answer to get paremeters for OpenLayers in appropirate format?</p>
<p>I checked that OpenLayers is able to parse WKT but it is impossible with BOX type.</p>

<p> </p>
<p>Thank for help!</p>
