[Geotools-gt2-users] Geotools 14.2 - write sld with SE version 1.1.0

[Andrea Lai]

Hi,

 

I am new to geotools. (windows 8.1 - geotols 14.2)
I am trying to write an .sld file with the "SE version 1.1.0".  (gt-xsd-sld
SEConfiguration) 
I have looked at this page
http://docs.geotools.org/stable/userguide/library/xml/style.html to get
started.
 
 
I also looked at the test in gt-xsd-sld; but all the test are for parsing an
sld file (I could not find and example that write a file ).
 
Are there any example?
There is something like  SLDTransformer?(for SE version 1.1.0)
 
 
 
I wrote this program (it works; but the output is not what i expected)
 
package org.geotools.tutorial;
 
import org.geotools.factory.CommonFactoryFinder;
import org.geotools.se.v1_1.SEConfiguration;
import org.geotools.styling.*;
import org.geotools.styling.Stroke;
import org.geotools.xml.Encoder;
import org.opengis.filter.FilterFactory;
 
import javax.xml.transform.TransformerException;
import java.awt.*;
import java.io.*;

public class TestSE {
    public static void main(String[] args) throws IOException,
TransformerException {
 
        // very simple style and SLD
-----------------------------------------------
        FilterFactory ff = CommonFactoryFinder.getFilterFactory2();
        StyleFactory sf = CommonFactoryFinder.getStyleFactory();
 
        Stroke stroke = sf.createStroke(ff.literal(Color.RED),
ff.literal(2));
        LineSymbolizer lineSymbolizer = sf.createLineSymbolizer(stroke,
null);
 
        Rule rule = sf.createRule();
        rule.symbolizers().add(lineSymbolizer);
 
        FeatureTypeStyle featureTypeStyle = sf.createFeatureTypeStyle(new
Rule[]{rule});// save to SE ver. 1.1.0
        featureTypeStyle.setName("TEST for SE 1.1.0 and SLD 1.0");
 
        Style style = sf.createStyle();
        style.featureTypeStyles().add(featureTypeStyle);
 
        StyledLayerDescriptor styledLayerDescriptor =
sf.createStyledLayerDescriptor(); // save to SLD ver. 1.0
        NamedLayer namedLayer = sf.createNamedLayer();
 
        namedLayer.styles().add(style);
        styledLayerDescriptor.layers().add(namedLayer);
 
 
        // write SLD version 1.0
---------------------------------------------------------------
        FileWriter sldFileWriter = new FileWriter(new
File("SLDver_1_0.sld"));
        SLDTransformer aTransformer = new SLDTransformer();
        aTransformer.setIndentation(4);
        aTransformer.transform(styledLayerDescriptor, sldFileWriter);
 
 
        // write SE version 1.1.0
------------------------------------------------------------------
        // http://docs.geotools.org/stable/userguide/library/xml/style.html
        org.geotools.xml.Configuration configuration = new
SEConfiguration();
        // configuration.setupBindings();
        Encoder encoder = new org.geotools.xml.Encoder( configuration );
        OutputStream outputStream = new FileOutputStream("SEver_1_1_0.XML");
        encoder.encode(featureTypeStyle ,
org.geotools.se.v1_1.SE.FeatureTypeStyle , outputStream);
 
//--------------------------------------------------------------------------
----------------
    }
}
 
 
SEver_1_1_0.XML (this is the output)
 
<?xml version="1.0" encoding="UTF-8"?>
<se:FeatureTypeStyle xmlns:xs="http://www.w3.org/2001/XMLSchema";
                xmlns:se="http://www.opengis.net/se";
                xmlns:ogc="http://www.opengis.net/ogc";>
