It&#39;s work I make this:<br><br>function createSLD(layer){<br>                var rules=[];<br>        for(var i=0;i&lt;layer.styleMap.styles.default.rules.length;i++){<br>            rules[i]=layer.styleMap.styles.default.rules[i];<br>
        }<br>             var defaultStyle = new OpenLayers.Style(&quot;default&quot;, {<br>                    rules: rules,<br>            name:&quot;default&quot;,<br>            isDefault:true<br>                });<br>
        rules=[];<br>        for(var i=0;i&lt;layer.styleMap.styles.select.rules.length;i++){<br>            rules[i]=layer.styleMap.styles.select.rules[i];<br>        }<br>        var selectStyle = new OpenLayers.Style(&quot;select&quot;, {<br>
                    rules: rules,<br>            name:&quot;select&quot;,<br>                });<br><br>                var sld = new OpenLayers.Format.SLD().write({<br>                    namedLayers: [{<br>                        name: <a href="http://layer.name">layer.name</a>,<br>
                        userStyles: [defaultStyle,selectStyle]<br>                    }]<br>                });<br>                return sld;<br>            }<br><br>Just a little problem : I use externalGraphics for Point and size is by default to 6? How can I specify the size of externalGraphics?<br>
<br>Thanks for help.<br><br>Jim<br clear="all"><br><pre>The StyleMap is no 1:1 representation of an SLD document. So you would<br>e.g. have to do the following:<br><br>var rule = new OpenLayers.Rule({<br>    filter: yourFilter<br>
});<br>rule.symbolizer[yourGeometryType(point|line|polygon)] = yourSymbolizer;<br>var style = new OpenLayers.Style(&quot;&quot;, {rules: [rule]});<br>var sld = new OpenLayers.Format.SLD().write({<br>    namedLayers: [{<br>
