Using batik-rasterizer.jar from version 1.7 of batik, I was wondering how to call the jar correctly.
java -jar batik-rasterizer-1.7.jar -m image/png -q 0.8 $1
Which gave me:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/batik/i18n/LocalizableSupport
Therefore, I was looking for the correct MainClass and ClassPath to use. I'll post a script I came up with as an answer in a minute ...
This would be the maven repackage approach:
You should get a "shaded" jar file target/com.bitplan.rasterizer-0.0.1.jar which already has the java.awt.headless call included:
You could also use the pom.xml "standalone" and simply change the main class in there.
Rasterize.java wrapper class
package com.bitplan.rasterizer;
import org.apache.batik.apps.rasterizer.Main;
/**
* Rasterizer main class
* https://stackoverflow.com/questions/13112967/how-to-call-batik-rasterizer-jar
* @author wf
*
*/
public class Rasterizer {
/**
* wrapper entry point for batik rasterizer
* @param args
*/
public static void main(String[] args) {
System.setProperty("java.awt.headless", "true");
// see
// http://www.docjar.org/html/api/org/apache/batik/apps/rasterizer/Main.java.html
Main main=new Main(args);
main.execute();
}
}
TestRasterizer.java JUnit testcase
package com.bitplan.rasterizer;
import static org.junit.Assert.*;
import java.io.File;
import org.junit.Test;
/**
* test the rasterizer
* @author wf
*
*/
public class TestRasterizer {
@Test
public void testRasterizer() {
File testFile=new File("src/test/data/redandblue.svg");
File pngFile=new File("src/test/data/redandblue.png");
if (pngFile.exists())
pngFile.delete();
assertTrue(testFile.exists());
String [] args={"-scriptSecurityOff","-m","image/png","-q","0.8",testFile.getPath()};
com.bitplan.rasterizer.Rasterizer.main(args);
assertTrue(pngFile.exists());
}
}

This script gets all necessary jars from the maven repository into a classpath variable. Probably there is a better way e.g. repacking using maven ...
#!/bin/bash
#set -x
batikdir=$HOME/.m2/repository/org/apache/xmlgraphics/batik-rasterizer/1.7/
batik=batik-rasterizer-1.7.jar
main=org.apache.batik.apps.rasterizer.Main
jarlist=/tmp/jarlist$$.txt
cp=$batikdir/$batik
find $HOME/.m2/repository -type f -name *.jar > $jarlist
for j in batik-ext-1.7.jar batik-dom-1.7.jar batik-css-1.7.jar batik-svg-dom-1.7.jar batik-gvt-1.7.jar batik-parser-1.7.jar batik-script-1.7.jar batik-bridge-1.7.jar batik-anim-1.7.jar batik-transcoder-1.7.jar batik-awt-util-1.7.jar batik-codec-1.7.jar batik-util-1.7.jar batik-xml-1.7.jar xerces-2.5.0.jar xalan-2.6.0.jar xml-apis-1.3.04.jar xml-apis-ext-1.3.04.jar fop-0.94.jar batik-js.jar
do
#echo $j
p=`grep $j $jarlist`
cp="$cp:$p"
done
#echo $cp
# http://tech.groups.yahoo.com/group/svg-developers/message/47939
java -cp $cp $main -scriptSecurityOff -m image/png -q 0.8 $1
rm -f $jarlist
to get the libraries i created a dummy maven project with the following pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!--
install maven 2 to use this pom file
run e.g. mvn dependency:go-offline to download all libraries
