<faq id="how-use">
<question>How do I use the PDF Plugin ?</question>
<answer>
<p/>
<ul>
<li>First you must call the maven target <code>site</code> to generate all the xdocs files and the image ressources.</li>
<li>Then you can call the <code>pdf</code> target to generate the pdf documentation for your project.</li>
</ul>
<p>To automate the pdf creation you can add a post goal to the site like this :</p>
<source><![CDATA[
<postGoal name="site">
<attainGoal name="pdf"/>
</postGoal>
]]></source>

<faq id="how-use-multiproject">
<question>How do I use the PDF Plugin with a multiproject ?</question>
<answer>
<p>To generate a PDF from documentations defined in several sub-projects, you must copy all the xdocs files from these projects.</p>
<p>Here is an example on how to do it :</p>
<source><![CDATA[
<attainGoal name="multiproject:site"/>
<maven:reactor
basedir="${basedir}"
postProcessing="true"
includes="**/project.xml"
collectOnly="true"
ignoreFailures="false"
collectionVar="multiprojects"/>
<!-- We copy the generated files to use them in the pdf -->
<j:forEach var="reactorProject" items="${multiprojects}">
<j:set var="fromDir" value="${reactorProject.context.getVariable('maven.gen.docs')}"/>
<ant:copy todir="${maven.build.dir}/pdf/${maven.multiproject.aggregateDir}${reactorProject.artifactId}">
<ant:fileset dir="${fromDir}" force="true">
<ant:include name="**/*.*"/>
</ant:fileset>
</ant:copy>
</j:forEach>
<attainGoal name="pdf"/>
]]></source>
<p>You can also createa dynamic menu using Velocity macro in your navigation.xml file. For example :</p>
<source><![CDATA[
<project name="$pom.name">
<body>
<links/>
<menu name="Overview">
#if ($overviewPageCreate == "true" )
<item name="${overviewPageLinkTitle}" href="${overviewPageLink}.html"/>
#end
</menu>
<menu name="Sub-Projects">
#foreach ($reactorProject in $multiprojects)
<item name="$reactorProject.name" href="/${aggregateDir}${reactorProject.artifactId}/index.html"/>
<item name="$reactorProject.name test" href="/${aggregateDir}${reactorProject.artifactId}/test.html"/>
#end
</menu>
</body>
</project>
]]></source>

<faq id="how-images">
<question>Which types of images can I use in my documents ?</question>
<answer>
<p>You can use images types that <a href="http://xml.apache.org/fop/graphics.html">FOP</a> can use.</p>

<faq id="how-png">
<question>How can I insert png images in my pdf ?</question>
<answer>
<p>You must download and put somewhere on your disk JAI or JIMI (on your repository is a good place for it).</p>
<p>Then you must register the one you installed with for JIMI :</p>
<source>maven.jar.jimi=${maven.repo.local}/jimi/jars/jimi-X.Y.Z.jar</source>
<p>Or for JAI :</p>
<source>maven.jar.jaicore=${maven.repo.local}/jai/jars/jai_core-X.Y.Z.jar
maven.jar.jaicodec=${maven.repo.local}/jai/jars/jai_codec-X.Y.Z.jar</source>
