[mapserver-users] Problems labelling using Halo option

[David Alda Fernandez de Lezea]

Hi list,

I'm developing a program that generates some images from a WMS with a dynamic generated SLD. The problem is that I'm telling MapServer to generate some labels with Halo, to make them easy to read, using the following code:

<NamedLayer>
<Name>vinedos</Name>
<UserStyle><Name></Name><Title></Title><Abstract></Abstract>
<FeatureTypeStyle>
<Rule>
<Filter>
<And>
<PropertyIsEqualTo><PropertyName>provincia</PropertyName><Literal>1</Literal></PropertyIsEqualTo>
<PropertyIsEqualTo><PropertyName>municipio</PropertyName><Literal>43</Literal></PropertyIsEqualTo>
<PropertyIsEqualTo><PropertyName>poligono</PropertyName><Literal>4</Literal></PropertyIsEqualTo>
<PropertyIsEqualTo><PropertyName>parcela</PropertyName><Literal>880</Literal></PropertyIsEqualTo>
<PropertyIsEqualTo><PropertyName>recinto</PropertyName><Literal>1</Literal></PropertyIsEqualTo>
</And>
</Filter>
<PolygonSymbolizer>
<Stroke>
<CssParameter name="stroke">#000000</CssParameter>
<CssParameter name="stroke-width">2</CssParameter>
<CssParameter name="stroke-dasharray">5 5 5 5</CssParameter>
</Stroke>
</PolygonSymbolizer>
<TextSymbolizer>
<Label>
<PropertyName>poligono</PropertyName>-<PropertyName>parcela</PropertyName>-<PropertyName>recinto</PropertyName>
</Label>
<Font>
<CssParameter name="font-family">times</CssParameter>
<CssParameter name="font-size">18</CssParameter>
<CssParameter name="font-weight">bold</CssParameter>
</Font>
<LabelPlacement>
<PointPlacement>
<AnchorPoint><AnchorPointX>0.5</AnchorPointX><AnchorPointY>0.5</AnchorPointY>
</AnchorPoint>
</PointPlacement>
</LabelPlacement>
<Halo>
<Radius>
<Literal>2</Literal>
</Radius>
<Fill>
<CssParameter name="fill">#FFFFFF</CssParameter>
<CssParameter name="fill-opacity">0.85</CssParameter>
</Fill>
</Halo>
<Fill>
<CssParameter name="fill">#000000</CssParameter>
<CssParameter name="fill-opacity">0.65</CssParameter>
</Fill>
</TextSymbolizer>
</Rule>
</FeatureTypeStyle>
</UserStyle>
</NamedLayer>

But when I receive the image the Halo is not applied (see attached file). My mapfile is as follows:

END

And my font file:

esri-130                esri_130.ttf
times				times.ttf
times-bold			timesbd.ttf
arial				arial.ttf

No error messages are received.
 
Any ideas??

Thanks.
 
Un saludo,
