[mapserver-users] Usage of Vendor Option

[David Alda Fernandez de Lezea]

Hi Barend, 

Sorry, I didn't know there was a problem with my emails. I've removed the styling-format of my email.

I'll repeat my question in case, someone didn't read the email because of that problem you mentioned.

I've got a SLD that I apply to a polygon layer and I want to add a label to identify those polygons. I manage to add the the labels but my problem is that the labels are repeated a lot of times into the polygons and furthermore they don't appear on the centroif of my polygon. Here is my TextSymbolizer tag:
 
<TextSymbolizer>
        <sld:MinScaleDenominator>3000</sld:MinScaleDenominator>
        <sld:MaxScaleDenominator>5000</sld:MaxScaleDenominator>
        <Label>
         <ogc:PropertyName>MUNICIPIO</ogc:PropertyName>         
        </Label> 
        <Font> 
         <CssParameter name="font-family">Arial</CssParameter> 
         <CssParameter name="font-weight">bold</CssParameter> 
         <CssParameter name="font-size">8</CssParameter> 
        </Font> 
        <!-- this centers the label on the polygon's centroid-->
        <LabelPlacement>
          <PointPlacement> 
          <AnchorPoint>
            <AnchorPointX>0.5</AnchorPointX>
            <AnchorPointY>0.5</AnchorPointY>
          </AnchorPoint>
          </PointPlacement>         
        </LabelPlacement>
         <!--  make the label easy to read-->
        <Halo>        
           <Radius>
           <ogc:Literal>2</ogc:Literal>
           </Radius>
           <Fill>
          <CssParameter name="fill">#FFFFFF</CssParameter>
          <CssParameter name="fill-opacity">0.85</CssParameter>    
           </Fill>
        </Halo>
        <Fill>
         <CssParameter name="fill">#000000</CssParameter>  
        </Fill>
        <!-- This labels each name only once, not every shape with that name -->
        <VendorOption name="group">true</VendorOption>
  </TextSymbolizer>

Hope that somenone can help me.

Thanks.





Hi David,

On a totally different subject: Are you aware that on some email readers (mine certainly), all your emails are viryually unreadable becuase your logo keeps getting repeated in the backgorund (see atached screenshot)?
