Hello,
I think I found an idea from where is coming my problem of opacity.
Maybe from a bad creation of Style, when reading the SLD...
First, I wrote this SLD :
<StyledLayerDescriptor version="0.7.2">
<!-- a named layer is the basic building block of an sld document -->
<NamedLayer>
<Name>A Random Layer</Name>
<title>The title of the layer</title>
<abstract>
A longer and some would say less random peice of text
that allows you to describe the layer in more detail
</abstract>
<!-- with in a layer you have Named Styles -->
<UserStyle xmlns:ogc="http://www.opengis.net";>
<!-- again they have names, titles and abstracts -->
<Name>TestStyle</Name>
<Title>Transparency style</Title>
<Abstract>A style to test transparency provider</Abstract>
<FeatureTypeStyle>
<Name>Des points</Name>
<Title>Un style pour des points en forme d'étoile</Title>
<Abstract>Ce style comporte une transparence pour le
remplissage</Abstract>
<FeatureTypeName>SIMPLE_PLACE</FeatureTypeName>
<rule>
<Name>Le point</Name>
<Title>Point design</Title>
<PointSymbolizer>
<graphic>
<geometry><propertyname>the_geom</propertyname></geometry>
<mark>
<wellknownname>star</wellknownname>
<Fill>
<CssParameter name="fill">#FF0000</CssParameter>
<CssParameter
name="fill-opacity">0.3</CssParameter>
</Fill>
<Stroke>
<CssParameter
name="stroke">#FFC800</CssParameter>
<CssParameter
name="stroke-linecap">butt</CssParameter>
<CssParameter
name="stroke-linejoin">round</CssParameter>
<CssParameter
name="stroke-opacity">1.0</CssParameter>
<CssParameter
name="stroke-width">1.0</CssParameter>
<CssParameter
name="stroke-dashoffset">0.0</CssParameter>
</Stroke>
</mark>
<Size>80</Size>
<Rotation>20.0</Rotation>
</graphic>
</PointSymbolizer>
</rule>
</FeatureTypeStyle>
</UserStyle>
</NamedLayer>
</StyledLayerDescriptor>
And this code :
URL sld = _2_SimplePlace.class.getResource("/resources/test1.xml");
SLDParser parser = new SLDParser(new StyleFactoryImpl());
parser.setInput(sld);
Style ptStyle = parser.readXML()[0];
Symbolizer s =
ptStyle.getFeatureTypeStyles()[0].getRules()[0].getSymbolizers()[0];
PointSymbolizer ps = (PointSymbolizer)s;
System.out.println("mark size = "+ ps.getGraphic().getMarks()[0].getSize());
System.out.println("fill opacity = "+
ps.getGraphic().getMarks()[0].getFill().getOpacity());
System.out.println("fill color = "+
ps.getGraphic().getMarks()[0].getFill().getColor());
But when I see my stars, there is no filling in it. Even though, I got this
result on the console :
mark size = 80
fill opacity = 0.3
fill color = #FF0000
So next I tried to add this little piece of code after loading the SLD :
StyleBuilder sb = new StyleBuilder();
Fill fill = sb.createFill(Color.red, 0.3);
ps.getGraphic().getMarks()[0].setFill(fill);
System.out.println("fill opacity = "+
ps.getGraphic().getMarks()[0].getFill().getOpacity());
And with it, this is working fine !!!
And the result on the console is :
mark size = 80
fill opacity = 0.3
fill color = #FF0000
fill opacity = 0.3
So do you think it is really a problem in SLD loader ? If it is, is it
possible to fix it quickly ?
If it is not...what did I do wrong ? ;-)
Thanks,
Thomas
