uDig uses transparency all the time. Maybe you can download a copy
generate a simple point style and check out the SLD it generates to
see if there is a difference. The SLD looks ok as far as I can tell.

Hello.
I posted few days ago for my problem, but nobody answered. So I am
going to try to explain in a better way, hoping somebody will be
able to answer...
I am currently simply trying to enter information into my system.
When I click on the map, I add a feature to a MemoryDataStore. This
feature has the following schema :
private static final String identifier = "SensorSite";
DataUtilities.createType(identifier,
"the_geom:MultiPoint,Name:String,TElev:Double");
I want to use the semi-transparency, to see my rasters through my
points (and eventually other types of features).
I wrote an SLD style, like this :
<?xml version="1.0" encoding="UTF-8"?>
<UserStyle xmlns:ogc="http://www.opengis.net";>
<FeatureTypeStyle>
<!-- This part specifies the point symbol -->
<Rule>
<PointSymbolizer>
<Geometry>
<ogc:PropertyName>the_geom</ogc:PropertyName>
</Geometry>
<Graphic>
<Mark>
<WellKnownName>star</WellKnownName>
<Fill>
<CssParameter name="fill">#ee3b3b</
CssParameter>
<CssParameter name="fill-opacity">0.5</
CssParameter>
</Fill>
<Stroke>
<CssParameter name="stroke">#0000ee</
CssParameter>
<CssParameter name="stroke-opacity">1</
CssParameter>
<CssParameter name="stroke-width">1</
CssParameter>
</Stroke>
</Mark>
<Size>20.0</Size>
</Graphic>
</PointSymbolizer>
</Rule>
<!-- This part specifies the label name -->
<Rule>
<TextSymbolizer>
<Label>
<ogc:PropertyName>Name</ogc:PropertyName>
</Label>
<LabelPlacement>
<PointPlacement>
<AnchorPoint>
<AnchorPointX>1.0</AnchorPointX>
<AnchorPointY>0.5</AnchorPointY>
</AnchorPoint>
<Displacement>
<DisplacementX>-10</DisplacementX>
<DisplacementY>-5</DisplacementY>
</Displacement>
</PointPlacement>
</LabelPlacement>
<Font/>
<Fill>
<CssParameter name="fill">#0000ff</CssParameter>"
</Fill>
<Halo/>
</TextSymbolizer>
</Rule>
</FeatureTypeStyle>
</UserStyle>
I load this SLD with the following methods :
public static Style getSensorSiteLayerStyle(){
URL sld = MSS_Map.class.getResource("/resources/styles/
site.xml");
SLDParser parser = new SLDParser(new StyleFactoryImpl());
try{
parser.setInput(sld);
}catch(IOException ioe){
ioe.printStackTrace();
}
return parser.readXML()[0]
}
sensorSiteLayer = new DefaultMapLayer(fsSites,
getSensorSiteLayerStyle());
sensorSiteLayer.setTitle("Sensor sites");
context.addLayer(sensorSiteLayer);
unfortunately, in this configuration, When I display a sensor site,
the star is not filled... because of this line : <CssParameter
name="fill-opacity">0.5</CssParameter>
(If I put the value 1, i got the filling !)
I tried for many other datas... all the time, if I put a fille-
opacity parameter, I don't have the good rendering (the part semi-
transparent is never displayed)...
Is there somebody to give me an idea ?
Thanks,
Thomas
