[OpenLayers-Users] SLD for Openlayers. Need some help.

[Rahn Hanno (rahn)]

Hello list,

 

My english ist not very well but I will try it in English. :-)

 

Perhaps somebody can help me.

I try to use SLD Documents with OpenLayers. I have a WMS Polygon Layer in my page like this:

 

<div style="width:300; height:300; border:4px ridge silver; position:absolute; top:64; left:485; float:left;margin:4px" id="map2"></div>

 

              <script defer="defer" type="text/javascript">

 

 

 

var options = {

                                               maxExtent: new OpenLayers.Bounds(649990.818704,222409.340625,736164.431296,284821.471875),

                                               //maxResolution: 10000,

                                               //tileSize: new OpenLayers.Size (200,200),

                                               units: 'm',

                                               projection: "EPSG:4149"

                                   };

 

                                   var map2 = new OpenLayers.Map('map2',options);

 

                                   

                                   var wmsX = new OpenLayers.Layer.WMS("Gemeinden","http://localhost/cgi-bin/mapserv.exe?", {map:"C:/Daten/TestDaten/Map_Dateien/Kanton_ZH_Gemeinden.map",layers:"gemeinden",format:"image/png",EXCEPTIONS:"application/vnd.ogc.se_inimage"},{singleTile: true} );

                                   map2.addLayer(wmsX);

 

            

                                   map2.zoomToMaxExtent();

 

                          </script> 

 

 

Now I will use al SLD File to style the map instaed of the original style from the wms. The polygons should have a colour in different categories from an attribut. For this I made a SLD-File "gemsee.sld" like this:

 

<?xml version="1.0" encoding="ISO-8859-1"?>

<sld:UserStyle xmlns="http://www.opengis.net/sld" xmlns:sld="http://www.opengis.net/sld" xmlns:ogc="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml">

                <ogc:Literal>0.5</ogc:Literal>

              </sld:AnchorPointY>

            </sld:AnchorPoint>

            <sld:Displacement>

              <sld:DisplacementX>

                <ogc:Literal>0</ogc:Literal>

              </sld:DisplacementX>

              <sld:DisplacementY>

                <ogc:Literal>0</ogc:Literal>

              </sld:DisplacementY>

            </sld:Displacement>

            <sld:Rotation>

              <ogc:Literal>0</ogc:Literal>

            </sld:Rotation>

        <sld:Fill>

          <sld:CssParameter name="fill">

          <sld:CssParameter name="fill-opacity">

          </sld:CssParameter>

        </sld:Fill>

      </sld:TextSymbolizer>

    </sld:Rule>

  </sld:FeatureTypeStyle>

</sld:UserStyle>

 

 

 Now I will use this SLD File to style the map. Is this possible? Can perhaps somebody give me some code? Of course I read the examples, but it didn't work. In the Future I will use one SLD for different Layers.

 

Can somebody help me please? A lot of thanks for you.

 

Greetings Hanno
