<title>Apache™ FOP: Ant task</title>
<version>$Revision$</version>
</header>
<body>
<p>
Apache™ FOP provides an Ant task for automating the document build process.
</p>
<section id="basics">
<title>Description</title>
<p>
The FOP Ant task will convert XSL-FO documents to PDF, PS, PCL etc. output
(see <a href="output.html">Output formats</a> for available formats).
</p>
<p>
To call FOP tasks within Ant, first add a FOP task definition to your Ant build file.
One method of defining the task is as follows:
</p>
<source><![CDATA[
<property name="fop.home" value="....path to your FOP HOME directory..."/>
<taskdef name="fop"
classname="org.apache.fop.tools.anttasks.Fop">
<classpath>
<fileset dir="${fop.home}/lib">
<include name="*.jar"/>
</fileset>
<fileset dir="${fop.home}/build">
<include name="fop.jar"/>
<include name="fop-hyph.jar" />
</fileset>
</classpath>
</taskdef>
]]></source>
<p>
Then create FOP tasks within your Ant build file, using the FOP task parameters listed below.</p>

<title>Examples</title>
<p>
The following example converts a single XSL-FO file to a PDF document:
</p>
<source><![CDATA[
<target name="generate-pdf" description="Generates a single PDF file">
<fop format="application/pdf"
fofile="c:\working\foDirectory\foDocument.fo"
outfile="c:\working\pdfDirectory\pdfDocument.pdf" />
</target>
]]></source>
<p>
This example converts all XSL-FO files within an entire directory to PostScript:
</p>
<source><![CDATA[
<target name="generate-multiple-ps"
description="Generates multiple PostScript files">
<fop format="application/postscript"
outdir="${build.dir}" messagelevel="debug">
<fileset dir="${fo.examples.dir}">
<include name="*.fo"/>
</fileset>
</fop>
</target>
]]></source>
<p>
The following example transforms and converts a single XML and XSLT file to an AFP document:
</p>
<source><![CDATA[

<fop format="application/x-afp"
xmlfile="c:\working\foDirectory\Document.xml"
