Ant task
FOP provides an Ant task for automating the document build process.
Description
The FOP Ant task will convert XSL-FO documents to PDF/PS/PCL/MIF/RTF output (see Output formats for available formats).
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:
<property name="fop.dir" value="....path to your FOP jar files..."/>
<taskdef name="fop"
classname="org.apache.fop.tools.anttasks.Fop">
<classpath>
<pathelement location="${fop.dir}\fop.jar"/>
<pathelement location="${fop.dir}\avalon.jar"/>
<pathelement location="${fop.dir}\batik.jar"/>
</classpath>
</taskdef>
Then create FOP tasks within your Ant build file, using the FOP task parameters listed below.
Parameters for FOP Ant task
| Attribute | Description | Required |
|---|---|---|
| fofile | XSL-FO file to be rendered | Yes, if no fileset nested element is used |
| outfile | Output filename | Yes, when fofile is used. (This attribute is not valid for filesets.) |
| format | Possible output formats: application/pdf application/postscript application/vnd.mif application/rtf application/vnd.hp-PCL text/plain text/xml |
No, defaults to application/pdf |
| outdir | Output directory | Required if a fileset is used to specify the files to render; optional for fofile. (Can alternatively specify the full path in the fofile value.) |
| force | Recreate target files, even if they are newer than their corresponding source files. Note: This attribute is available in post-0.20.5 versions (0.20.x nightly build and 1.0dev) only; target files are always generated (i.e., force=true) in 0.20.5 release. | No, default is false |
| basedir | Base directory to resolve relative references (e.g., graphics files) within the FO document. | No, for single FO File entry, default is to use the location of that FO file. |
| relativebase | For fileset usage only. A value of true specifies using the location of each .fo file as the base directory for resolving relative file references located within that .fo file. A value of false specifies using the value of basedir for all files within the fileset, or just the current working directory if basedir is not specified. | No, default is false. |
| userconfig | User configuration file (same as the FOP "-c" command line option) | No |
| messagelevel | Logging level Possible values: error, warn, info, verbose, debug |
No, defaults to verbose |
| logFiles | Controls whether the names of the files that are processed are logged (true) or not (false) | No, default is true |
| Attribute | Description | Required |
|---|---|---|
| fileset | FileSets are used to specify multiple XSL-FO files to be rendered. | Yes, if no fofile attribute is supplied |
Examples
The following example converts a single XSL-FO file to a PDF document:
<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>
This example converts all XSL-FO files within an entire directory to PostScript:
<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>
