- <description>FOP (Formatting Objects Processor) is the world's first print formatter driven by XSL formatting objects (XSL-FO) and the world's first output independent formatter. It is a Java application that reads a formatting object (FO) tree and renders the resulting pages to a specified output. Output formats currently supported include PDF, PCL, PS, SVG, XML (area tree representation), Print, AWT, MIF and TXT. The primary output target is PDF.</description>

- <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>

- </section>

- <title>Apache™ FOP: Building from Source Code</title>

- <version>$Revision$</version>

- </header>

- <body>

- <section id="build-needed">

- <title>Do You Need To Build?</title>

- <p>

- Apache™ FOP distributions are either pre-compiled binary or source.

- If you are using a binary distribution, it is already built and there is no need to build it again.

- See the <a href="../download.html">Download Instructions</a> for information about whether a

- binary or source distribution is best for your needs.

- </p>

- <p>

- If you got the source code from a repository snapshot or via Subversion you will need to build FOP

- in any case.

- </p>

- </section>

- <section id="env">

- <title>Set Up Your Environment</title>

- <section id="env-jdk">

- <title>JDK</title>

- <p>

- Building FOP requires a minimum Java Development Kit (JDK/SDK) of 1.4

- (A Java Runtime Environment is not sufficient).

- </p>

- </section>

- <section id="env-classpath">

- <title>CLASSPATH</title>

- <p>

- There is generally no need to setup a classpath. All libraries needed to compile FOP are included

- in the source distribution and are referenced by the build script.

- You will only need to adjust the classpath if you build FOP in some other way. See the build

- script build.xml for details.

- </p>

- </section>

- <section id="env-java-home">

- <title>JAVA_HOME</title>

- <p>

- The build script uses <a href="ext:ant">Apache Ant</a>, a popular

- Java-based build tool, which usually requires that the environment variable JAVA_HOME point to

- your local JDK root directory. This is true even if you use JDK 1.4 or above, which normally

- does not need this setting.

- </p>

- </section>

- <section id="env-ant">

- <title>Apache Ant</title>

- <p>

- <a href="ext:ant">Apache Ant</a> (Version 1.7 or later) must be installed in order to

- build FOP. Following best practices we don't include Ant with FOP anymore. You can find the

- <a href="ext:ant/manual/">instructions to install Ant in the Ant manual</a> on the web.

- </p>

- </section>

- </section>

- <section id="build-script">

- <title>Run the Build Script</title>

- <p>

- Change to the FOP root directory and build FOP by executing the build script (build.xml)

- using the "ant" command.

- </p>

- <note>

- The "ant" command is only available on your system if you've properly

- <a href="ext:ant/manual/">installed Apache Ant</a> and added Ant's location to the PATH

- environment variable.

- </note>

- <p>

- The file build.xml in the FOP root directory is the blueprint that Ant uses for the build. It

- contains information for numerous build targets, many of which are building blocks to more

- useful target, and others which are primarily used by the FOP developers.

- You may benefit from looking through this file to learn more about the various build targets.

- To obtain a complete list of useful build targets:

- </p>

- <source>ant -projecthelp</source>

- <p>The most useful targets are:</p>

- <ul>

- <li>

- <strong>package</strong>: Generates the JAR files (default). This is the normal build that

- produces a jar file usable for running FOP.

- </li>

- <li>

- <strong>clean </strong>: Cleans the build directory. This is useful for making sure that

- any build errors are cleaned up before starting a new build. It should not ordinarily be

- needed, but may be helpful if you are having problems with the build process itself.

- </li>

- <li>

- <strong>javadocs</strong>: Creates the FOP API documentation.

- <note>A minimum JDK version of 1.4.2 is required for generating the javadocs.</note>

- </li>

- </ul>

- <p>To run the build:</p>

- <source>ant [target ...]</source>

- <p>For example to do a normal build for the "all" target (which is the default):</p>

- <source>ant</source>

- <title>Configuration File Basics</title>

- <p>

- The FOP configuration file is an XML file containing a variety of settings that are useful

- for controlling FOP's behavior, and for helping it find resources that you wish it to use.

- </p>

- <p>

- The easiest way to get started using a FOP configuration file is to copy the sample found

- at <code>{fop-dir}/conf/fop.xconf</code> to a location of your choice, and then to

- edit it according to your needs.

- It contains templates for the various configuration options, most of which are commented

- out. Remove the comments and change the settings for entries that you wish to use.

- Be sure to follow any instructions, including comments which specify the value range.

- Also, since the configuration file is XML, be sure to keep it well-formed.

- </p>

- <section id="general-available">

- <title>Making Configuration Available to FOP</title>

- <p>After creating your configuration file, you must tell FOP how to find it:</p>

- <ul>

- <li>

- If running FOP from the command-line, see the "-c" command-line option in

- <a href="running.html">Running FOP</a>.

- </li>

- <li>

- If running FOP as an embedded application, see

- <a href="embedding.html#config-external">Embedding, Using a Configuration File</a>.

- </li>

- </ul>

- <p>

- See <a href="embedding.html#config-internal">Setting the Configuration Programmatically</a>

- for instructions on how to do so in an embedded environment.

- <section id="renderers">

- <title>Renderer configuration</title>

- <p>

- Each Renderer has its own configuration section which is identified by the

- MIME type the Renderer is written for, ex. "application/pdf" for the PDF Renderer.

- </p>

- <p>

- The configuration for the PDF Renderer could look like this:

- </p>

- <source><![CDATA[

- <renderers>

- <renderer mime="application/pdf">

- <filterList>

- <!-- provides compression using zlib flate (default is on) -->

- <value>flate</value>

- </filterList>

- <fonts>

- <font metrics-url="arial.xml" kerning="yes" embed-url="arial.ttf">

- <font-triplet name="Arial" style="normal" weight="normal"/>

- <font-triplet name="ArialMT" style="normal" weight="normal"/>

- </font>

- <font metrics-url="arialb.xml" kerning="yes" embed-url="arialb.ttf">

- <font-triplet name="Arial" style="normal" weight="bold"/>

- <font-triplet name="ArialMT" style="normal" weight="bold"/>

- </font>

- </fonts>

- </renderer>

-

- <renderer mime="application/postscript">

- <!-- etc. etc..... -->]]></source>

- <p>

- The details on the font configuration can be found on the separate <a href="fonts.html">Fonts</a> page.

- Note especially the section entitled <a href="fonts.html#register">Register Fonts with FOP</a>.

- </p>

- <section id="pdf-renderer">

- <title>Special Settings for the PDF Renderer</title>

- <p>

- The configuration element for the PDF renderer contains two elements. One is for the font configuration

- (please follow the link above) and one is for the "filter list". The filter list controls how the

- individual objects in a PDF file are encoded. By default, all objects get "flate" encoded (i.e. simply

- compressed with the same algorithm that is also used in ZIP files). Most users don't need to change that

- setting. For debugging purposes, it may be desired not to compress the internal objects at all so the

- generated PDF commands can be read. In that case, you can simply use the following filter list. The

- second filter list (type="image") ensures that all images still get compressed but also ASCII-85 encoded

- so the produced PDF file is still easily readable in a text editor.

- </p>

- <source><![CDATA[

- <renderer mime="application/pdf">

- <filterList>

- <value>null</value>

- </filterList>

- <filterList type="image">

- <value>flate</value>

- <value>ascii-85</value>

- </filterList>

-

- <fonts....

- </renderer>]]></source>

- <p>

- Another (optional) setting specific to the PDF Renderer is an output color profile, an ICC

- color profile which indicates the target color space the PDF file is generated for. This

- setting is mainly used in conjunction with the <a href="pdfx.html">PDF/X</a> feature.

- An example:

- </p>

- <source><![CDATA[

- <renderer mime="application/pdf">

- <filterList...

-

- <output-profile>C:\FOP\Color\EuropeISOCoatedFOGRA27.icc</output-profile>

-

- <fonts....

- </renderer>]]></source>

- <p>

- Some people don't have high requirements on color fidelity but instead want the smallest

- PDF file sizes possible. In this case it's possible to disable the default sRGB color space

- which XSL-FO requires. This will cause RGB colors to be generated as device-specific RGB.

- Please note that this option is unavailable (and will cause an error) if you enable

- PDF/A or PDF/X functionality or if you specify an output profile. This setting will make the

- PDF about 4KB smaller. To disable the sRGB color space add the following setting:

- </p>

- <source><![CDATA[

- <renderer mime="application/pdf">

- <filterList...

-

- <disable-srgb-colorspace>true</disable-srgb-colorspace>

-

- <fonts....

- </renderer>]]></source>

- </section>

- <section id="ps-renderer">

- <title>Special Settings for the PostScript Renderer</title>

- <p>

- Besides the normal font configuration (the same "fonts" element as for the PDF renderer) the PostScript

- renderer has an additional setting to force landscape pages to be rotated to fit on a page inserted into

- the printer in portrait mode. Set the value to "true" to activate this feature. The default is "false".

- Example:

- </p>

- <source><![CDATA[

- <renderer mime="application/postscript">

- <auto-rotate-landscape>true</auto-rotate-landscape>

-

- <fonts>

- <font metrics-url="arial.xml" kerning="yes" embed-url="arial.ttf">

- <font-triplet name="Arial" style="normal" weight="normal"/>

- <font-triplet name="ArialMT" style="normal" weight="normal"/>

- </font>

- <font metrics-url="arialb.xml" kerning="yes" embed-url="arialb.ttf">

- <font-triplet name="Arial" style="normal" weight="bold"/>

- <font-triplet name="ArialMT" style="normal" weight="bold"/>

- </font>

- </fonts>

- </renderer>]]></source>

- </section>

- <section id="pcl-renderer">

- <title>Special Settings for the PCL Renderer</title>

- <p>

- Non-standard fonts for the PCL renderer are made available through the Java2D subsystem which means that

- you don't have to do any custom font configuration in this case but you have to use the font names

- offered by Java.

- </p>

- <p>

- Additionally, there are certain settings that control how the renderer handles various elements.

- </p>

-<source><![CDATA[<renderer mime="application/vnd.hp-PCL">

- <rendering>quality</rendering>

- <text-rendering>bitmap</text-rendering>

-</renderer>]]></source>

- <p>

- The default value for the "rendering" setting is "speed" which causes borders

- to be painted as plain rectangles. In this mode, no special borders (dotted,

- dashed etc.) are available. If you want support for all border modes, set the

- value to "quality" as indicated above. This will cause the borders to be painted

- as bitmaps.

- </p>

- <p>

- The default value for the "text-rendering" setting is "auto" which paints the

- base fonts using PCL fonts. Non-base fonts are painted as bitmaps through Java2D.

- If the mix of painting methods results in unwelcome output, you can set this

- to "bitmap" which causes all text to be rendered as bitmaps.

- <title>When it does not work</title>

-

- <p>FOP searches the configuration file for the information it

-expects, at the position it expects. When that information is not

-present, FOP will not complain, it will just continue. When there is

-other information in the file, FOP will not complain, it will just

-ignore it. That means that when your configuration information is in

-the file but in a different XML element, or in a different XML path,

-than FOP expects, it will be silently ignored.</p>

-

- <p>Check the following possibilities:</p>

-

- <ul>

- <li>The format of the configuration file has changed

-considerably between FOP 0.20.5 and FOP 1.0 and its beta versions. Did

-you convert your file to the new format?</li>

-

- <li>The FOP distribution contains a schema for configuration

-files, at src/foschema/fop-configuration.xsd. Did you validate your

-configuration file against it? Add the following schema location to

-the <code>schema</code> element:

-

-<source><![CDATA[<fop

-xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

-xsi:noNamespaceSchemaLocation=

-"http://svn.apache.org/viewvc/xmlgraphics/fop/trunk/src/foschema/fop-configuration.xsd?view=co">]]>

-</source>

-

-and run the configuration file through a validating schema

-parser. Note that the schema cannot detect all errors, and that it is

-stricter about the order of some elements than FOP itself is.</li>

-

- <li>Run FOP in debug mode (command line option

-<code>-d</code>). This makes FOP report which configuration

-information it finds. Check if FOP finds what you expect.</li>

- <title>Overview</title>

- <p>

- Review <a href="running.html">Running Apache™ FOP</a> for important information that applies

- to embedded applications as well as command-line use, such as options and performance.

- </p>

- <p>

- To embed Apache™ FOP in your application, first create a new

- org.apache.fop.apps.FopFactory instance. This object can be used to launch multiple

- rendering runs. For each run, create a new org.apache.fop.apps.Fop instance through

- one of the factory methods of FopFactory. In the method call you specify which output

- format (i.e. Renderer) to use and, if the selected renderer requires an OutputStream,

- which OutputStream to use for the results of the rendering. You can customize FOP's

- behaviour in a rendering run by supplying your own FOUserAgent instance. The

- FOUserAgent can, for example, be used to set your own Renderer instance (details

- below). Finally, you retrieve a SAX DefaultHandler instance from the Fop object and

- use that as the SAXResult of your transformation.

- </p>

- <note>

- We recently changed FOP's outer API to what we consider the final API. This might require

- some changes in your application. The main reasons for these changes were performance

- improvements due to better reuse of reusable objects and reduced use of static variables

- for added flexibility in complex environments.

- </note>

- </section>

- <section id="basics">

- <title>Basic Usage Pattern</title>

- <p>

- Apache FOP relies heavily on JAXP. It uses SAX events exclusively to receive the XSL-FO

- input document. It is therefore a good idea that you know a few things about JAXP (which

- is a good skill anyway). Let's look at the basic usage pattern for FOP...

- </p>

- <p>Here is the basic pattern to render an XSL-FO file to PDF:

- </p>

- <source><![CDATA[

-import org.apache.fop.apps.FopFactory;

-import org.apache.fop.apps.Fop;

-import org.apache.fop.apps.MimeConstants;

-

-/*..*/

-

-// Step 1: Construct a FopFactory

-// (reuse if you plan to render multiple documents!)

-FopFactory fopFactory = FopFactory.newInstance();

-

-// Step 2: Set up output stream.

-// Note: Using BufferedOutputStream for performance reasons (helpful with FileOutputStreams).

-OutputStream out = new BufferedOutputStream(new FileOutputStream(new File("C:/Temp/myfile.pdf")));

-

-try {

- // Step 3: Construct fop with desired output format

- Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, out);

-

- // Step 4: Setup JAXP using identity transformer

- TransformerFactory factory = TransformerFactory.newInstance();

- Transformer transformer = factory.newTransformer(); // identity transformer

-

- // Step 5: Setup input and output for XSLT transformation

- // Setup input stream

- Source src = new StreamSource(new File("C:/Temp/myfile.fo"));

-

- // Resulting SAX events (the generated FO) must be piped through to FOP

- Result res = new SAXResult(fop.getDefaultHandler());

-

- // Step 6: Start XSLT transformation and FOP processing

- transformer.transform(src, res);

-

-} finally {

- //Clean-up

- out.close();

-}]]></source>

- <p>

- Let's discuss these 5 steps in detail:

- </p>

- <ul>

- <li>

- <strong>Step 1:</strong> You create a new FopFactory instance. The FopFactory instance holds

- references to configuration information and cached data. It's important to reuse this

- instance if you plan to render multiple documents during a JVM's lifetime.

- </li>

- <li>

- <strong>Step 2:</strong> You set up an OutputStream that the generated document

- will be written to. It's a good idea to buffer the OutputStream as demonstrated

- to improve performance.

- </li>

- <li>

- <strong>Step 3:</strong> You create a new Fop instance through one of the factory

- methods on the FopFactory. You tell the FopFactory what your desired output format

- is. This is done by using the MIME type of the desired output format (ex. "application/pdf").

- You can use one of the MimeConstants.* constants. The second parameter is the

- OutputStream you've setup up in step 2.

- </li>

- <li>

- <strong>Step 4</strong> We recommend that you use JAXP Transformers even

- if you don't do XSLT transformations to generate the XSL-FO file. This way

- you can always use the same basic pattern. The example here sets up an

- "identity transformer" which just passes the input (Source) unchanged to the

- output (Result). You don't have to work with a SAXParser if you don't do any

- XSLT transformations.

- </li>

- <li>

- <strong>Step 5:</strong> Here you set up the input and output for the XSLT

- transformation. The Source object is set up to load the "myfile.fo" file.

- The Result is set up so the output of the XSLT transformation is sent to FOP.

- The FO file is sent to FOP in the form of SAX events which is the most efficient

- way. Please always avoid saving intermediate results to a file or a memory buffer

- because that affects performance negatively.

- </li>

- <li>

- <strong>Step 6:</strong> Finally, we start the XSLT transformation by starting

- the JAXP Transformer. As soon as the JAXP Transformer starts to send its output

- to FOP, FOP itself starts its processing in the background. When the

- <code>transform()</code> method returns FOP will also have finished converting

- the FO file to a PDF file and you can close the OutputStream.

- <note label="Tip!">

- It's a good idea to enclose the whole conversion in a try..finally statement. If

- you close the OutputStream in the finally section, this will make sure that the

- OutputStream is properly closed even if an exception occurs during the conversion.

- </note>

- </li>

- </ul>

- <p>

- If you're not totally familiar with JAXP Transformers, please have a look at the

- <a href="#examples">Embedding examples</a> below. The section contains examples

- for all sorts of use cases. If you look at all of them in turn you should be able

- to see the patterns in use and the flexibility this approach offers without adding

- too much complexity.

- </p>

- <p>

- This may look complicated at first, but it's really just the combination of an

- XSL transformation and a FOP run. It's also easy to comment out the FOP part

- for debugging purposes, for example when you're tracking down a bug in your

- stylesheet. You can easily write the XSL-FO output from the XSL transformation

- to a file to check if that part generates the expected output. An example for that

- can be found in the <a href="#examples">Embedding examples</a> (See "ExampleXML2FO").

- </p>

- <section id="basic-logging">

- <title>Logging</title>

- <p>

- Logging is now a little different than it was in FOP 0.20.5. We've switched from

- Avalon Logging to <a href="ext:commons-logging">Jakarta Commons Logging</a>.

- While with Avalon Logging the loggers were directly given to FOP, FOP now retrieves

- its logger(s) through a statically available LogFactory. This is similar to the

- general pattern that you use when you work with Apache Log4J directly, for example.

- We call this "static logging" (Commons Logging, Log4J) as opposed to "instance logging"

- (Avalon Logging). This has a consequence: You can't give FOP a logger for each

- processing run anymore. The log output of multiple, simultaneously running FOP instances

- is sent to the same logger.

- </p>

- <note>

- We know this may be an issue in multi-threaded server environments if you'd like to

- know what's going on in every single FOP processing run. We're planning to add an

- additional feedback facility to FOP which can be used to obtain all sorts of specific

- feedback (validation messages, layout problems etc.). "Static logging" is mainly

- interesting for a developer working on FOP and for advanced users who are debugging

- FOP. We don't consider the logging output to be useful to normal FOP users. Please

- have some patience until we can add this feature or jump in and help us build it. We've

- set up a <a href="http://wiki.apache.org/xmlgraphics-fop/ProcessingFeedback">Wiki page</a>

- which documents what we're going to build.

- </note>

- <p>

- By default, <a href="ext:commons-logging">Jakarta Commons Logging</a> uses

- JDK logging (available in JDKs 1.4 or higher) as its backend. You can configure Commons

- Logging to use an alternative backend, for example Log4J. Please consult the

- <a href="ext:commons-logging">documentation for Jakarta Commons Logging</a> on

- how to configure alternative backends.

- </p>

- <section id="render">

- <title>Processing XSL-FO</title>

- <p>

- Once the Fop instance is set up, call <code>getDefaultHandler()</code> to obtain a SAX

- DefaultHandler instance to which you can send the SAX events making up the XSL-FO

- document you'd like to render. FOP processing starts as soon as the DefaultHandler's

- <code>startDocument()</code> method is called. Processing stops again when the

- DefaultHandler's <code>endDocument()</code> method is called. Please refer to the basic

- usage pattern shown above to render a simple XSL-FO document.

- </p>

- </section>

-

- <section id="render-with-xslt">

- <title>Processing XSL-FO generated from XML+XSLT</title>

- <p>

- If you want to process XSL-FO generated from XML using XSLT we recommend

- again using standard JAXP to do the XSLT part and piping the generated SAX

- events directly through to FOP. The only thing you'd change to do that

- on the basic usage pattern above is to set up the Transformer differently:

- <title>Input Sources</title>

- <p>

- The input XSL-FO document is always received by FOP as a SAX stream (see the

- <a href="../dev/design/parsing.html">Parsing Design Document</a> for the rationale).

- </p>

- <p>

- However, you may not always have your input document available as a SAX stream.

- But with JAXP it's easy to convert different input sources to a SAX stream so you

- can pipe it into FOP. That sounds more difficult than it is. You simply have

- to set up the right Source instance as input for the JAXP transformation.

- A few examples:

- </p>

- <ul>

- <li>

- <strong>URL:</strong> <code>Source src = new StreamSource("http://localhost:8080/testfile.xml");</code>

- </li>

- <li>

- <strong>File:</strong> <code>Source src = new StreamSource(new File("C:/Temp/myinputfile.xml"));</code>

- </li>

- <li>

- <strong>String:</strong> <code>Source src = new StreamSource(new StringReader(myString)); // myString is a String</code>

- </li>

- <li>

- <strong>InputStream:</strong> <code>Source src = new StreamSource(new MyInputStream(something));</code>

- </li>

- <li>

- <strong>Byte Array:</strong> <code>Source src = new StreamSource(new ByteArrayInputStream(myBuffer)); // myBuffer is a byte[] here</code>

- </li>

- <li>

- <strong>DOM:</strong> <code>Source src = new DOMSource(myDocument); // myDocument is a Document or a Node</code>

- </li>

- <li>

- <strong>Java Objects:</strong> Please have a look at the <a href="#examples">Embedding examples</a> which contain an example for this.

- </li>

- </ul>

- <p>

- There are a variety of upstream data manipulations possible.

- For example, you may have a DOM and an XSL stylesheet; or you may want to

- set variables in the stylesheet. Interface documentation and some cookbook

- solutions to these situations are provided in

- <a href="http://xml.apache.org/xalan-j/usagepatterns.html">Xalan Basic Usage Patterns</a>.

- <title>Configuring Apache FOP Programmatically</title>

- <p>

- Apache FOP provides two levels on which you can customize FOP's

- behaviour: the FopFactory and the user agent.

- </p>

- <section id="fop-factory">

- <title>Customizing the FopFactory</title>

- <p>

- The FopFactory holds configuration data and references to objects which are reusable over

- multiple rendering runs. It's important to instantiate it only once (except in special

- environments) and reuse it every time to create new FOUserAgent and Fop instances.

- </p>

- <p>

- You can set all sorts of things on the FopFactory:

- </p>

- <ul>

- <li>

- <p>

- The <strong>font base URL</strong> to use when resolving relative URLs for fonts. Example:

- </p>

- <source>fopFactory.setFontBaseURL("file:///C:/Temp/fonts");</source>

- </li>

- <li>

- <p>

- The <strong>hyphenation base URL</strong> to use when resolving relative URLs for

- hyphenation patterns. Example:

- </p>

- <source>fopFactory.setHyphenBaseURL("file:///C:/Temp/hyph");</source>

- </li>

- <li>

- <p>

- Disable <strong>strict validation</strong>. When disabled FOP is less strict about the rules

- established by the XSL-FO specification. Example:

- </p>

- <source>fopFactory.setStrictValidation(false);</source>

- </li>

- <li>

- <p>

- Enable an <strong>alternative set of rules for text indents</strong> that tries to mimic the behaviour of many commercial

- FO implementations, that chose to break the specification in this respect. The default of this option is

- 'false', which causes Apache FOP to behave exactly as described in the specification. To enable the

- alternative behaviour, call:

- </p>

- <source>fopFactory.setBreakIndentInheritanceOnReferenceAreaBoundary(true);</source>

- </li>

- <li>

- <p>

- Set the <strong>source resolution</strong> for the document. This is used internally to determine the pixel

- size for SVG images and bitmap images without resolution information. Default: 72 dpi. Example:

- </p>

- <source>fopFactory.setSourceResolution(96); // =96dpi (dots/pixels per Inch)</source>

- </li>

- <li>

- <p>

- Manually add an <strong>ElementMapping instance</strong>. If you want to supply a special FOP extension

- you can give the instance to the FOUserAgent. Normally, the FOP extensions can be automatically detected

- (see the documentation on extension for more info). Example:

- </p>

- <source>fopFactory.addElementMapping(myElementMapping); // myElementMapping is a org.apache.fop.fo.ElementMapping</source>

- </li>

- <li>

- <p>

- Set a <strong>URIResolver</strong> for custom URI resolution. By supplying a JAXP URIResolver you can add

- custom URI resolution functionality to FOP. For example, you can use

- <a href="ext:xml.apache.org/commons/resolver">Apache XML Commons Resolver</a> to make use of XCatalogs. Example:

- </p>

- <source>fopFactory.setURIResolver(myResolver); // myResolver is a javax.xml.transform.URIResolver</source>

- <note>

- Both the FopFactory and the FOUserAgent have a method to set a URIResolver. The URIResolver on the FopFactory

- is primarily used to resolve URIs on factory-level (hyphenation patterns, for example) and it is always used

- if no other URIResolver (for example on the FOUserAgent) resolved the URI first.

- </note>

- </li>

- </ul>

- </section>

- <section id="user-agent">

- <title>Customizing the User Agent</title>

- <p>

- The user agent is the entity that allows you to interact with a single rendering run, i.e. the processing of a single

- document. If you wish to customize the user agent's behaviour, the first step is to create your own instance

- of FOUserAgent using the appropriate factory method on FopFactory and pass that

- to the factory method that will create a new Fop instance:

- </p>

- <source><![CDATA[

- FopFactory fopFactory = FopFactory.newInstance(); // Reuse the FopFactory if possible!

- // do the following for each new rendering run

- FOUserAgent userAgent = fopFactory.newFOUserAgent();

- // customize userAgent

- Fop fop = fopFactory.newFop(MimeConstants.MIME_POSTSCRIPT, userAgent, out);]]></source>

- <p>

- You can do all sorts of things on the user agent:

- </p>

- <ul>

- <li>

- <p>

- The <strong>base URL</strong> to use when resolving relative URLs. Example:

- </p>

- <source>userAgent.setBaseURL("file:///C:/Temp/");</source>

- </li>

- <li>

- <p>

- Set the <strong>producer</strong> of the document. This is metadata information that can be used for certain output formats such as PDF. The default producer is "Apache FOP". Example:

- </p>

- <source>userAgent.setProducer("MyKillerApplication");</source>

- </li>

- <li>

- <p>

- Set the <strong>creating user</strong> of the document. This is metadata information that can be used for certain output formats such as PDF. Example:

- </p>

- <source>userAgent.setCreator("John Doe");</source>

- </li>

- <li>

- <p>

- Set the <strong>author</strong> of the document. This is metadata information that can be used for certain output formats such as PDF. Example:

- </p>

- <source>userAgent.setAuthor("John Doe");</source>

- </li>

- <li>

- <p>

- Override the <strong>creation date and time</strong> of the document. This is metadata information that can be used for certain output formats such as PDF. Example:

- </p>

- <source>userAgent.setCreationDate(new Date());</source>

- </li>

- <li>

- <p>

- Set the <strong>title</strong> of the document. This is metadata information that can be used for certain output formats such as PDF. Example:

- </p>

- <source>userAgent.setTitle("Invoice No 138716847");</source>

- </li>

- <li>

- <p>

- Set the <strong>keywords</strong> of the document. This is metadata information that can be used for certain output formats such as PDF. Example:

- </p>

- <source>userAgent.setKeywords("XML XSL-FO");</source>

- </li>

- <li>

- <p>

- Set the <strong>target resolution</strong> for the document. This is used to

- specify the output resolution for bitmap images generated by bitmap renderers

- (such as the TIFF renderer) and by bitmaps generated by Apache Batik for filter

- effects and such. Default: 72 dpi. Example:

- </p>

- <source>userAgent.setTargetResolution(300); // =300dpi (dots/pixels per Inch)</source>

- </li>

- <li>

- <p>

- Set <strong>your own Renderer instance</strong>. If you want to supply your own renderer or

- configure a Renderer in a special way you can give the instance to the FOUserAgent. Normally,

- the Renderer instance is created by FOP. Example:

- </p>

- <source>userAgent.setRendererOverride(myRenderer); // myRenderer is an org.apache.fop.render.Renderer</source>

- </li>

- <li>

- <p>

- Set <strong>your own FOEventHandler instance</strong>. If you want to supply your own FOEventHandler or

- configure an FOEventHandler subclass in a special way you can give the instance to the FOUserAgent. Normally,

- the FOEventHandler instance is created by FOP. Example:

- </p>

- <source>userAgent.setFOEventHandlerOverride(myFOEventHandler); // myFOEventHandler is an org.apache.fop.fo.FOEventHandler</source>

- </li>

- <li>

- <p>

- Set a <strong>URIResolver</strong> for custom URI resolution. By supplying a JAXP URIResolver you can add

- custom URI resolution functionality to FOP. For example, you can use

- <a href="ext:xml.apache.org/commons/resolver">Apache XML Commons Resolver</a> to make use of XCatalogs. Example:

- </p>

- <source>userAgent.setURIResolver(myResolver); // myResolver is a javax.xml.transform.URIResolver</source>

- <note>

- Both the FopFactory and the FOUserAgent have a method to set a URIResolver. The URIResolver on the FOUserAgent is

- used for resolving URIs which are document-related. If it's not set or cannot resolve a URI, the URIResolver

- from the FopFactory is used.

- </note>

- </li>

- </ul>

- <note>

- You should not reuse an FOUserAgent instance between FOP rendering runs although you can. Especially

- in multi-threaded environment, this is a bad idea.

- Fop instances shouldn't (and can't) be reused. Please recreate

- <section id="awt">

- <title>AWT issues</title>

- <p>

- If your XSL-FO files contain SVG then Apache Batik will be used. When Batik is

- initialised it uses certain classes in <code>java.awt</code> that

- intialise the Java AWT classes. This means that a daemon thread

- is created by the JVM and on Unix it will need to connect to a

- DISPLAY.

- </p>

- <p>

- The thread means that the Java application may not automatically quit

- when finished, you will need to call <code>System.exit()</code>. These

- issues should be fixed in the JDK 1.4.

- </p>

- If you run into trouble running FOP on a head-less server, please see the

- </section>

- <section id="render-info">

- <title>Getting information on the rendering process</title>

- <p>

- To get the number of pages that were rendered by FOP you can call

- <code>Fop.getResults()</code>. This returns a <code>FormattingResults</code> object

- where you can look up the number of pages produced. It also gives you the

- page-sequences that were produced along with their id attribute and their

- numbers of pages. This is particularly useful if you render multiple

- documents (each enclosed by a page-sequence) and have to know the number of

- pages of each document.

- <section id="performance">

- <title>Improving performance</title>

- <p>

- There are several options to consider:

- </p>

- <ul>

- <li>

- Whenever possible, try to use SAX to couple the individual components involved

- (parser, XSL transformer, SQL datasource etc.).

- </li>

- <li>

- Depending on the target OutputStream (in case of a FileOutputStream, but not

- for a ByteArrayOutputStream, for example) it may improve performance considerably

- if you buffer the OutputStream using a BufferedOutputStream:

- <code>out = new java.io.BufferedOutputStream(out);</code>

- <br/>

- Make sure you properly close the OutputStream when FOP is finished.

- </li>

- <li>

- Cache the stylesheet. If you use the same stylesheet multiple times

- you can set up a JAXP <code>Templates</code> object and reuse it each time you do

- the XSL transformation. (More information can be found

- <a class="fork" href="http://www.javaworld.com/javaworld/jw-05-2003/jw-0502-xsl.html">here</a>.)

- </li>

- <li>

- Use an XSLT compiler like <a class="fork" href="http://xml.apache.org/xalan-j/xsltc_usage.html">XSLTC</a>

- that comes with Xalan-J.

- </li>

- <li>

- Fine-tune your stylesheet to make the XSLT process more efficient and to create XSL-FO that can

- be processed by FOP more efficiently. Less is more: Try to make use of property inheritance where possible.

- </li>

- </ul>

- <section id="multithreading">

- <title>Multithreading FOP</title>

- <p>

- Apache FOP may currently not be completely thread safe.

- The code has not been fully tested for multi-threading issues, yet.

- If you encounter any suspicious behaviour, please notify us.

- </p>

- <p>

- There is also a known issue with fonts being jumbled between threads when using

- the Java2D/AWT renderer (which is used by the -awt and -print output options).

- In general, you cannot safely run multiple threads through the AWT renderer.

-has nothing to do with FOP. It is there to show you how an XML

- example</a>

-demonstrates how you can convert an arbitrary XML file to PDF

-using XSLT and XSL-FO/FOP. It is a combination of the first two examples

-transform the XSL-FO to PDF.

- </p>

- <figure src="images/EmbeddingExampleXML2PDF.png" alt="Example XML to PDF (via XSL-FO)"/>

- <p>

-The output (XSL-FO) from the XSL transformation is piped through to FOP using

-SAX events. This is the most efficient way to do this because the

-intermediate result doesn't have to be saved somewhere. Often, novice users

-save the intermediate result in a file, a byte array or a DOM tree. We

-strongly discourage you to do this if it isn't absolutely necessary. The

- <p>This

- <a href="http://svn.apache.org/viewcvs.cgi/xmlgraphics/fop/trunk/examples/embedding/java/embedding/ExampleObj2XML.java?view=markup">

- example</a>

-is a preparatory example for the next one. It's an example that

-shows how an arbitrary Java object can be converted to XML. It's an often

-needed task to do this. Often people create a DOM tree from a Java object and

-use that. This is pretty straightforward. The example here, however, shows how

-to do this using SAX, which will probably be faster and not even more

-complicated once you know how this works.

- </p>

- <figure src="images/EmbeddingExampleObj2XML.png" alt="Example Java object to XML"/>

- <p>

-For this example we've created two classes: ProjectTeam and ProjectMember

-(found in xml-fop/examples/embedding/java/embedding/model). They represent

-the same data structure found in

-xml-fop/examples/embedding/xml/xml/projectteam.xml. We want to serialize to XML a

-project team with several members which exist as Java objects.

-Therefore we created the two classes: ProjectTeamInputSource and

-ProjectTeamXMLReader (in the same place as ProjectTeam above).

- </p>

- <p>

-The XMLReader implementation (regard it as a special kind of XML parser) is

-responsible for creating SAX events from the Java object. The InputSource

-class is only used to hold the ProjectTeam object to be used.

- <p>

-Have a look at the source of ExampleObj2XML.java to find out how this is

- <title>Namespace</title>

- <p>

- By convention, FO extensions in FOP use the "fox" namespace prefix.

- To use any of the FO extensions, add a namespace entry for

- <code>http://xmlgraphics.apache.org/fop/extensions</code> to the root element:

- </p>

- <source><![CDATA[<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format"

- xmlns:fox="http://xmlgraphics.apache.org/fop/extensions">]]></source>

- </section>

- <section id="bookmarks">

- <title>PDF Bookmarks</title>

- <p>

- In previous versions of Apache FOP there was a <code>fox:outline</code> element

- which was used to create outlines in PDF files. The redesigned code makes use

- of the new <a href="http://www.w3.org/TR/xsl11/#fo_bookmark-tree">bookmark feature defined in the latest XSL 1.1 working draft</a>.

- </p>

- </section>

- <section id="named-destinations">

- <title>Anchors or Named Destinations</title>

- <p>Use the fox:destination element to define "named destinations" inside a PDF document.

-These are useful as fragment identifiers, e.g. "http://server/document.pdf#anchor-name".

-fox:destination elements can be placed almost anywhere in the fo document, including a child of

-root, a block-level element, or an inline-level element.

-For the destination to actually work, it must correspond to an "id" attribute on some fo element

-within the document. In other words, the "id" attribute actually creates the "view" within the

-PDF document. The fox:destination simply gives that view an independent name.

-</p>

- <source><![CDATA[<fox:destination internal-destination="table-of-contents"/>

-...

-<fo:block id="table-of-contents">Table of Contents</fo:block>]]></source>

- <warning>It is possible that in some future release of FOP, <em>all </em>elements with

-appears. fox:continued-label is itself inline content, and is a container of fo:inline

-content. This content will be laid out only if the table does not fit on a single page and flows

-to following pages. Here is an example of FO code creating such a table-header:</p>

- <title>fox:orphan-content-limit and fox:widow-content-limit</title>

- <p>

- The two proprietary extension properties, fox:orphan-content-limit and

- fox:widow-content-limit, are used to improve the layout of list-blocks and tables.

- If you have a table with many entries, you don't want a single row to be left over

- on a page. You will want to make sure that at least two or three lines are kept

- together. The properties take an absolute length which specifies the area at the

- beginning (fox:widow-content-limit) or at the end (fox:orphan-content-limit) of a

- table or list-block. The properties are inherited and only have an effect on fo:table

- and fo:list-block. An example: fox:widow-content-limit="3 * 1.2em" would make sure

- the you'll have at least three lines (assuming line-height="1.2") together on a table

- <title>fox:external-document</title>

- <note>

- This feature is incomplete. Support for multi-page documents will be added shortly.

- At the moment, only single-page images will work. And this will not work with RTF output.

- </note>

- <p>

- This is a proprietary extension element which allows to add whole images as pages to

- an FO document. For example, if you have a scanned document or a fax as multi-page TIFF

- file, you can append or insert this document using the <code>fox:external-document</code>

- element. Each page of the external document will create one full page in the target

- format.

- </p>

- <p>

- The <code>fox:external-document</code> element is structurally a peer to

- <code>fo:page-sequence</code>, so wherever you can put an <code>fo:page-sequence</code>

- you could also place a <code>fox:external-document</code>.

- Therefore, the specified contents for <code>fo:root</code> change to:

- </p>

- <p>

- <code>

- (layout-master-set, declarations?, bookmark-tree?, (page-sequence|page-sequence-wrapper|fox:external-document|fox:destination)+)

- </code>

- </p>

- <section>

- <title>Specification</title>

- <p>

- The <code>fox:external-document</code> extension formatting object is used to specify

- how to create a (sub-)sequence of pages within a document. The content of these pages

- comes from the individual subimages/pages of an image or paged document (for example:

- multi-page TIFF in the form of faxes or scanned documents, or PDF files). The

- formatting object creates the necessary areas to display one image per page.

- </p>

- <p>

- In terms of page numbers, the behaviour is the same as for

- <code>fo:page-sequence</code>. The placement of the image inside the page is similar

- to that of <code>fo:external-graphic</code> or <code>fo:instream-foreign-object</code>,

- i.e. the viewport (and therefore the page size) is defined by either the intrinsic

- size of the image or by the size properties that apply to this formatting object.

- </p>

- <p>Content: EMPTY</p>

- <p>The following properties apply to this formatting object:</p>

- <ul>

- <li>(Common Accessibility Properties) (not implemented, yet)</li>

- <li>(Common Aural Properties) (not implemented, yet)</li>

- <li>block-progression-dimension</li>

- <li>content-height</li>

- <li>content-type</li>

- <li>content-width</li>

- <li>display-align</li>

- <li>height</li>

- <li>id</li>

- <li>inline-progression-dimension</li>

- <li>overflow</li>

- <li>pages: &lt;page-set&gt; (see below) (not implemented, yet)</li>

- <li>reference-orientation</li>

- <li>scaling</li>

- <li>scaling-method</li>

- <li>src</li>

- <li>text-align</li>

- <li>width</li>

- </ul>

- <p>

- Datatype "page-set": Value: auto | &lt;integer-range&gt;,

- Default: "auto" which means all pages/subimages of the document.

- &lt;integer-range&gt; allows values such as "7" or "1-3"

- </p>

- <note>

- <code>fox:external-document</code> is not suitable for concatenating FO documents.

- For this, XInclude is recommended.

- </note>

- <section id="transform">

- <title>Free-form Transformation for fo:block-container</title>

- <p>

- For <code>fo:block-container</code> elements whose <code>absolute-position</code> set to

- "absolute" or "fixed" you can use the extension attribute <code>fox:transform</code>

- to apply a free-form transformation to the whole block-container. The content of the

- <code>fox:transform</code> attribute is the same as for

- <a href="http://www.w3.org/TR/SVG/coords.html#TransformAttribute">SVG's transform attribute</a>.

- The transformation specified here is performed in addition to other implicit

- transformations of the block-container (resulting from top, left and other properties)

- and after them.

- </p>

- <p>

- Examples: <code>fox:transform="rotate(45)"</code> would rotate the block-container

- by 45 degrees clock-wise around its upper-left corner.

- <code>fox:transform="translate(10000,0)"</code> would move the block-container to the

- right by 10 points (=10000 millipoints, FOP uses millipoints internally!).

- </p>

- <note>

- This extension attribute doesn't work for all output formats! It's currently only

- supported for PDF, PS and Java2D-based renderers.

- <section id="color-functions">

- <title>Color functions</title>

- <p>

- XSL-FO supports specifying color using the rgb(), rgb-icc() and system-color() functions.

- Apache FOP provides additional color functions for special use cases. Please note that

- using these functions compromises the interoperability of an FO document.

- </p>

- <section id="color-function-cmyk">

- <title>cmyk()</title>

- <p><code>color cmyk(numeric, numeric, numeric, numeric)</code></p>

- <p>

- This function will construct a color in device-specific CMYK color space. The numbers

- must be between 0.0 and 1.0. For output formats that don't support device-specific

- color space the CMYK value is converted to an sRGB value.

- <title>Base-14 Fonts</title>

- <p>

- The Adobe PostScript and PDF Specification specify a set of 14 fonts that must be

- available to every PostScript interpreter and PDF reader:

- Helvetica (normal, bold, italic, bold italic),

- Times (normal, bold, italic, bold italic),

- Courier (normal, bold, italic, bold italic),

- Symbol and ZapfDingbats.

- </p>

- <p>

- Please note that recent versions of Adobe Acrobat Reader replace

- "Helvetica" with "Arial" and "Times" with "Times New Roman" internally.

- GhostScript replaces "Helvetica" with "Nimbus Sans L" and "Times" with

- "Nimbus Roman No9 L". Other document viewers may do similar font

- substitutions. If you need to make sure that there are no such

- substitutions, you need to specify an explicit font and embed it in

- the target document.

- </p>

- </section>

- <section>

- <title>Missing Fonts</title>

- <p>

- When FOP does not have a specific font at its disposal (because it's

- not installed in the operating system or set up in FOP's configuration),

- the font is replaced with "any". "any" is internally mapped to the

- Base-14 font "Times" (see above).

- </p>

- </section>

- <section id="awt">

- <title>Java2D/AWT/Operating System Fonts</title>

- <p>

- The Java2D family of renderers (Java2D, AWT, Print, TIFF, PNG), use the

- Java AWT subsystem for font metric information. Through operating system

- registration, the AWT subsystem knows what fonts are available on the system,

- and the font metrics for each one.

- </p>

- <p>

- When working with one of these output formats and you're missing a font, just

- install it in your operating system and they should be available for these

- renderers. Please note that this is not true for other output formats such as

- PDF or PostScript.

- </p>

- </section>

-

- <section id="custom">

- <title>Custom Fonts</title>

- <p>

- Support for custom fonts is highly output format dependent (see above table).

- This section shows how to add Type 1 and TrueType fonts to the PDF, PostScript and

- Java2D-based renderers. Other renderers (like AFP) support other font formats. Details

- in this case can be found on the page about <a href="output.html">output formats</a>.

- </p>

- <p>

- Prior to FOP version 0.94, it was always necessary to create an XML font metrics file

- if you wanted to add a custom font. This unconvenient step has been removed and in

- addition to that, FOP supports auto-registration of fonts, i.e. FOP can find fonts

- installed in your operating system or can scan user-specified directories for fonts.

- Font registration via XML font metrics file is still supported and is still necessary

- if you want to use a TrueType Collection (*.ttc). Direct support for TrueType

- collections may be added later. Furthermore, the XML font metrics files are still

- required if you don't want to embed, but only reference a font.

- </p>

- <p>

- Basic information about fonts can be found at:

- </p>

- <ul>

- <li><a href="http://partners.adobe.com/asn/developer/type/ftypes.html">Adobe font types</a></li>

- </ul>

- </section>

-

- <section id="basics">

- <title>Basic font configuration</title>

- <p>

- If you want FOP to use custom fonts, you need to tell it where to find them. This

- is done in the configuration file and once per renderer (because each output format

- is a little different). In the basic form, you can either tell FOP to find your

- operating system fonts or you can specify directories that it will search for

- support fonts. These fonts will then automatically be registered.

- </p>

- <source><![CDATA[

-<fonts>

- <!-- register all the fonts found in a directory -->

- <directory>C:\MyFonts1</directory>

-

- <!-- register all the fonts found in a directory

- and all of its sub directories (use with care) -->

- <directory recursive="true">C:\MyFonts2</directory>

-

- <!-- automatically detect operating system installed fonts -->

- <auto-detect/>

-</fonts>]]></source>

- <note>

- Review the documentation for <a href="configuration.html">FOP Configuration</a>

- for instructions on making the FOP configuration available to FOP when it runs.

- Otherwise, FOP has no way of finding your custom font information. It is currently

- not possible to easily configure fonts from Java code.

- </note>

- </section>

-

- <section id="advanced">

- <title>Advanced font configuration</title>

- <p>

- The instructions found above should be sufficient for most users. Below are some

- additional instructions in case the basic font configuration doesn't lead to

- the desired results.

- </p>

- <section id="type1-metrics">

- <title>Type 1 Font Metrics</title>

- <p>FOP includes PFMReader, which reads the PFM file that normally comes with a Type 1 font, and generates an appropriate font metrics file for it.

- To use it, run the class org.apache.fop.fonts.apps.PFMReader:</p>

- <p>Windows:</p>

- <source>java -cp build\fop.jar;lib\avalon-framework.jar;lib\commons-logging.jar;lib\commons-io.jar

- org.apache.fop.fonts.apps.PFMReader [options] pfm-file xml-file</source>

- <p>Unix:</p>

- <source>java -cp build/fop.jar:lib/avalon-framework.jar:lib/commons-logging.jar:lib/commons-io.jar

- org.apache.fop.fonts.apps.PFMReader [options] pfm-file xml-file</source>

- <p>PFMReader [options]:</p>

- <ul>

- <li><strong>-fn &lt;fontname&gt;</strong> By default, FOP uses the fontname from the

- .pfm file when embedding the font. Use the "-fn" option to override this name with one you have

- chosen. This may be useful in some cases to ensure that applications using the output document

- (Acrobat Reader for example) use the embedded font instead of a local font with the same

- name.</li>

- </ul>

- <note>The classpath in the above example has been simplified for readability.

- You will have to adjust the classpath to the names of the actual JAR files in the lib directory.

- xml-apis.jar, xercesImpl.jar, xalan.jar and serializer.jar are not necessary for JDK version 1.4 or later.</note>

- <note>The tool will construct some values (FontBBox, StemV and ItalicAngle) based on assumptions and calculations which are only an approximation to the real values.

- FontBBox and Italic Angle can be found in the human-readable part of the PFB file or in the AFM file.

- The PFMReader tool does not yet interpret PFB or AFM files, so if you want to be correct, you may have to adjust the values in the XML file manually.

- The constructed values however appear to have no visible influence.</note>

- </section>

- <section id="truetype-metrics">

- <title>TrueType Font Metrics</title>

- <p>FOP includes TTFReader, which reads the TTF file and generates an appropriate font metrics file for it.

- Use it in a similar manner to PFMReader.

- For example, to create such a metrics file in Windows from the TrueType font at c:\myfonts\cmr10.ttf:</p>

- <source>java -cp build\fop.jar;lib\avalon-framework.jar;lib\commons-logging.jar;lib\commons-io.jar

- org.apache.fop.fonts.apps.TTFReader [options]

- C:\myfonts\cmr10.ttf ttfcm.xml</source>

- <p>TTFReader [options]:</p>

- <ul>

- <li><strong>-d &lt;DEBUG | INFO &gt;</strong> Sets the debug level (default is

- INFO).</li>

- <li><strong>-fn &lt;fontname&gt;</strong> Same as for PFMReader.</li>

- <li><strong>-ttcname &lt;fontname&gt;</strong> If you're reading data from a

- TrueType Collection (.ttc file) you must specify which font from the collection you will read

- metrics from.

- If you read from a .ttc file without this option, the fontnames will be listed for you.</li>

- <li><strong>-enc ansi</strong> Creates a WinAnsi-encoded font metrics file.

- Without this option, a CID-keyed font metrics file is created.

- The table below summarizes the differences between these two encoding options as currently

- used within FOP.

- Please note that this information only applies to TrueType fonts and TrueType collections:</li>

- </ul>

- <table id="ttf-encoding">

- <tr>

- <th>Issue</th>

- <th>WinAnsi</th>

- <th>CID-keyed</th>

- </tr>

- <tr>

- <td>Usable Character Set</td>

- <td>Limited to WinAnsi character set, which is roughly equivalent to iso-8889-1.</td>

- <td>Limited only by the characters in the font itself.</td>

- </tr>

- <tr>

- <td>Embedding the Font</td>

- <td>Optional.</td>

- <td>Mandatory. Not embedding the font produces invalid PDF documents.</td>

- </tr>

- </table>

- <warning>

- You may experience failures with certain TrueType fonts, especially if they don't contain

- the so-called Unicode "cmap" table. TTFReader can currently not deal with font like this.

- </warning>

- </section>

- <section id="truetype-collections-metrics">

- <title>TrueType Collections Font Metrics</title>

- <p>TrueType collections (.ttc files) contain more than one font.

- To create metrics files for these fonts, you must specify which font in the collection should be generated, by using the "-ttcname" option with the TTFReader.</p>

- <p>To get a list of the fonts in a collection, just start the TTFReader as if it were a normal TrueType file (without the -ttcname option).

- It will display all of the font names and exit with an Exception.</p>

- <p>Here is an example of generating a metrics file for a .ttc file:</p>

- <source>java -cp build\fop.jar;lib\avalon-framework.jar;lib\commons-logging.jar;lib\commons-io.jar

- org.apache.fop.fonts.apps.TTFReader -ttcname "MS Mincho"

- msmincho.ttc msminch.xml</source>

- </section>

- <section id="register">

- <title>Register Fonts with FOP</title>

- <p>You must tell FOP how to find and use the font metrics files by registering them in the <a href="configuration.html">FOP Configuration</a>. Add entries for your custom fonts, regardless of font type, to the configuration file in a manner similar to the following:</p>

- <source><![CDATA[

-<fonts>

- <!-- register a particular font -->

- <font metrics-url="file:///C:/myfonts/FTL_____.xml" kerning="yes"

- embed-url="file:///C:/myfonts/FTL_____.pfb">

- <font-triplet name="FrutigerLight" style="normal" weight="normal"/>

- </font>

-

- <!-- register all the fonts found in a directory -->

- <directory>C:\MyFonts1</directory>

-

- <!-- register all the fonts found in a directory

- and all of its sub directories (use with care) -->

- <directory recursive="true">C:\MyFonts2</directory>

-

- <!-- automatically detect operating system installed fonts -->

- <auto-detect/>

-</fonts>]]></source>

- <ul>

- <li>

- URLs are used to access the font metric and font files.

- Relative URLs are resolved relative to the font-base property (or base) if available.

- See <a href="configuration.html">FOP: Configuration</a> for more information.

- </li>

- <li>The "metrics-url" attribute is generally not necessary except if you run into problems with certain fonts.</li>

- <li>Either an "embed-url" or a "metrics-url" must be specified for font tag configurations.</li>

- <li>The font "kerning" attribute is optional. Default is "true".</li>

- <li>If embedding is off (i.e. embed-url is not set), the output will position the text correctly (from the metrics file), but it will not be displayed or printed correctly unless the viewer has the applicable font available to their local system.</li>

- <li>When setting the "embed-url" attribute for Type 1 fonts, be sure to specify the PFB (actual font data), not PFM (font metrics) file that you used to generate the XML font metrics file.</li>

- <li>The fonts "directory" tag can be used to register fonts contained within a single or list of directory paths. The "recursive" attribute can be specified to recursively add fonts from all sub directories.</li>

- <li>The fonts "auto-detect" tag can be used to automatically register fonts that are found to be installed on the native operating system.</li>

- <li>Fonts registered with "font" tag configurations override fonts found by means of "directory" tag definitions.</li>

- <li>Fonts found as a result of a "directory" tag configuration override fonts found as a result of the "auto-detect" tag being specified.</li>

- <li>

- If relative URLs are specified, they are evaluated relative to the value of the

- "font-base" setting. If there is no "font-base" setting, the fonts are evaluated

- relative to the base directory.

- </li>

- </ul>

- <!--note>Cocoon users will need to setup the config, see FOPSerializer for more information.</note-->

- </section>

- <section id="autodetect">

- <title>Auto-Detect and auto-embedd feature</title>

- <p>When the "auto-detect" flag is set in the configuration, FOP will automatically search for fonts in the default paths for your operating system.</p>

- <p>FOP will also auto-detect fonts which are available in the classpath, if they are described as "application/x-font" in the MANIFEST.MF file. For example, if your .jar file contains font/myfont.ttf:</p>

- <source>Manifest-Version: 1.0

-

- Name: font/myfont.ttf

- Content-Type: application/x-font</source>

- <p>This feature allows you to create JAR files containing fonts. The JAR files can be added to fop by providem them in the classpath, e.g. copying them into the lib/ directory.</p>

- </section>

- <section id="embedding">

- <title>Embedding</title>

- <note>The PostScript renderer does not yet support TrueType fonts, but can embed Type 1 fonts.</note>

- <note>The font is simply embedded into the PDF file, it is not converted.</note>

- <p>Font embedding is enabled in the userconfig.xml file and controlled by the embed-url attribute.

- If you don't specify the embed-url attribute the font will not be embedded, but will only be referenced.</p>

- <warning>

- Omitting the embed-url attribute for CID-encoded TrueType fonts will currently produce invalid

- PDF files! If you create the XML font metric file using the "-enc ansi" option, you can omit

- the embed-url attribute for TrueType fonts but you're restricted to the WinAnsi character set.

- </warning>

- <p>When FOP embeds a font, it adds a prefix to the fontname to ensure that the name will not match the fontname of an installed font.

- This is helpful with older versions of Acrobat Reader that preferred installed fonts over embedded fonts.</p>

- <p>When embedding PostScript fonts, the entire font is always embedded.</p>

- <p>When embedding TrueType fonts (ttf) or TrueType Collections (ttc), a subset of the

- original font, containing only the glyphs used, is embedded in the output document.</p>

- </section>

- <!-- The following section should no longer be required

- <section id="embedding-base14">

- <title>Explicitly embedding the base 14 fonts</title>

- <p>

- There are cases where you might want to force the embedding of one or more of the base 14 fonts that

- can normally be considered available on the target platform (viewer, printer). One of these cases is

- <a href="pdfa.html">PDF/A</a> which mandates the embedding of even the base 14 fonts. Embedding a font such as Helvetica or

- Courier is straight-forward. The "Symbol" and "ZapfDingbats" fonts, however, currently present a

- problem because FOP cannot correctly determine the encoding of these two single-byte fonts through

- the PFM file. FOP now correctly interprets the "encoding" value in the XML font metrics file, but the

- PFMReader application writes "UnknownEncoding" to the generated XML file. In order to embed "Symbol"

- and "ZapfDingbats" you have to manually change the XML font metrics file and specify "SymbolEncoding"

- or "ZapfdingbatsEncoding" encoding respectively as the value for the "encoding" element.

- <ul>

- <li>

- The image libraries Jimi and JAI are no longer supported. Instead, Apache FOP uses the

- Image I/O API that was introduced with Java 1.4 for all bitmap codecs.

- </li>

- <li>

- Some bitmap images are no longer converted to a standardized 24 bit RGB image but are

- instead handled in their native format.

- </li>

- <li>

- A plug-in mechanism offers a possibility to add support for new formats without changing

- the FOP's source code.

- </li>

- </ul>

- <p>

- The actual <a href="http://xmlgraphics.apache.org/commons/image-loader.html">image loading framework</a>

- no longer resides in Apache FOP, but was instead placed in

- <a href="ext:xmlgraphics.apache.org/commons/">XML Graphics Commons</a>.

- <title>Overview of Graphics Support</title>

- <p>

- The table below summarizes the <em>theoretical</em> support for graphical formats

- within FOP. In other words, within the constraints of the limitations listed here,

- these formats <em>should</em> work. However, many of them have not been tested,

- and there may be limitations that have not yet been discovered or documented.

- The packages needed to support some formats are not included in the FOP distribution

- and must be installed separately. Follow the links in the "Support Through" columns

- for more details.

- <warning>Batik must be run in a graphical environment.</warning>

- <p>

- Batik must be run in a graphical environment.

- It uses AWT classes for rendering SVG, which in turn require an X server on Unixish

- systems. If you run a server without X, or if you can't connect to the X server due to

- security restrictions or policies (a so-called "headless" environment), SVG rendering

- will fail.

- <p>Here are some workarounds:</p>

- <ul>

- <li>

- Start Java with the <code>-Djava.awt.headless=true</code> command line option.

- <li>

- Install an X server which provides an in-memory framebuffer without actually using a

- screen device or any display hardware. One example is Xvfb.

- <p>

- FOP native support (i.e. the handling of undecoded images) of JPEG does not include all

- If you have trouble with a JPEG image in FOP, try opening it with an image processing

- program (such as Photoshop or Gimp) and then saving it. Specifying 24-bit color output

- may also help. For the PDF and PostScript renderers most JPEG images can be passed

- through without decompression. User reports indicate that grayscale, RGB, and

- CMYK color spaces are all rendered properly. However, for other output formats, the

- JPEG images have to be decompressed. Tests have shown that there are some limitation

- in some Image&amp;nbsp;I/O codecs concerning images in the CMYK color space. Work-arounds are

- <title>Introduction</title>

- <p>FOP uses <a href="#batik"> Apache Batik</a> for SVG support.

- This format can be handled as an <code>fo:instream-foreign-object</code> or in a separate

- <note>

- Batik's SVG Rasterizer utility may also be used to convert standalone SVG

- documents into PDF. For more information please see the

- <a href="http://xmlgraphics.apache.org/batik/svgrasterizer.html">SVG Rasterizer documentation</a>

- on the Batik site.

- </note>

- </section>

- <section id="svg-pdf-graphics">

- <title>Placing SVG Graphics into PDF</title>

- <p>

- The SVG is rendered into PDF by using PDF commands to draw and fill

- lines and curves. This means that the graphical objects created with

- this remain as vector graphics. The same applies to PostScript output.

- For other output formats the SVG graphic may be converted to a bitmap

- image.

- </p>

- <p>

- There are a number of SVG things that cannot be converted directly into

- PDF. Parts of the graphic such as effects, patterns and images are inserted

- into the PDF as a raster graphic. The resolution of these raster images can

- be controlled through the "target resolution" setting in the

- <a href="configuration.html">configuration</a>.</p>

- <p>

- Currently transparency is limited in PDF so many SVG images that

- contain effects or graphics with transparent areas may not be displayed

- correctly.

- </p>

- </section>

- <section id="svg-pdf-text">

- <title>Placing SVG Text into PDF and PostScript</title>

- <p>If possible, Batik will use normal PDF or PostScript text when inserting text. It does

- this by checking if the text can be drawn normally and the font is

- supported. This example svg <a href="../dev/svg/text.svg">text.svg</a> /

- <!--link href="../dev/svg/text.pdf"-->text.pdf<!--/link-->

- shows how various types and effects with text are handled.

- Note that tspan and outlined text are not yet implemented.</p>

- <p>

- Otherwise, text is converted and drawn as a set of shapes by Batik, using the

- stroking text painter. This means that a typical character will

- have about 10 curves (each curve consists of at least 20 characters).

- This can make the output files large and when it is viewed the

- viewer may not normally draw those fine curves very well (In Adobe Acrobat, turning on

- "Smooth Line Art" in the preferences will fix this). Copy/paste functionality

- will not be supported in this case.

- If the text is inserted into the output file using the inbuilt text commands

- it will use a single character.

- </p>

- <p>

- Note that because SVG text can be rendered as either text or a vector graphic, you

- may need to consider settings in your viewer for both. The Acrobat viewer has both

- "smooth line art" and "smooth text" settings that may need to be set for SVG images

- to be displayed nicely on your screen (see Edit / Preferences / Display).

- This setting will not affect the printing of your document, which should be OK in

- any case, but will only affect the quality of the screen display.</p>

- </section>

- <section id="svg-scaling">

- <title>Scaling</title>

- <p>

- Currently, SVG images are rendered with the dimensions specified <em>in the SVG

- file</em>, within the viewport specified in the fo:external-graphic element.

- For everything to work properly, the two should be equal. The SVG standard leaves

- this issue as an implementation detail. Additional scaling options are available

- through XSL-FO means.

- </p>

- <p>

- If you use pixels to specify the size of an SVG graphic the "source resolution" setting

- in the <a href="configuration.html">configuration</a> will be used to determine the

- size of a pixel. The use of pixels to specify sizes is discouraged as they may

- be interpreted differently in different environments.

- </p>

- </section>

- <section id="svg-problems">

- <title>Known Problems</title>

- <ul>

- <li>

- Soft mask transparency is combined with white so that it looks better

- on PDF 1.3 viewers but this causes the soft mask to be slightly lighter

- or darker on PDF 1.4 viewers.

- </li>

- <li>

- There is some problem with a gradient inside a pattern which may cause a PDF

- error when viewed in Acrobat 5.

- </li>

- <li>

- Text is not always handled correctly, it may select the wrong font

- especially if characters have multiple fonts in the font list.

- </li>

- <li>

- Uniform transparency for images and other SVG elements that are converted

- into a raster graphic are not drawn properly in PDF. The image is opaque.

- </li>

- </ul>

- </section>

- </section>

- <section id="tiff">

- <title>TIFF</title>

- <p>

- FOP can embed TIFF images without decompression into PDF, PostScript and AFP if they

- have either CCITT T.4, CCITT T.6, or JPEG compression. Otherwise, a TIFF-capable

- Image&amp;nbsp;I/O codec is necessary for decoding the image.

- </p>

- <p>

- There may be some limitation concerning images in the CMYK color space.

- </p>

- </section>

- <section id="wmf">

- <title>WMF</title>

- <p>

- Windows Metafiles (WMF) are supported through classes in

- <a href="ext:xmlgraphics.apache.org/batik">Apache Batik</a>. At the moment, support

- for this format is experimental and may not always work as expected.

- </p>

- </section>

- </section>

- <section id="resolution">

- <title>Graphics Resolution</title>

- <p>

- Some bitmapped image file formats store a dots-per-inch (dpi) or other resolution

- values. FOP tries to use this resolution information whenever possible to determine

- the image's intrinsic size. This size is used during the layout process when it is not

- superseded by an explicit size on fo:external-graphic (content-width and content-height

- properties).

- </p>

- <p>

- Please note that not all images contain resolution information. If it's not available

- the source resolution set on the FopFactory (or through the user configuration XML) is used.

- The default here is 72 dpi.

- </p>

- <p>

- Bitmap images are generally embedded into the output format at their original resolution

- (as is). No resampling of the image is performed. Explicit resampling is on our wishlist,

- but hasn't been implemented, yet. Bitmaps included in SVG graphics may be resampled to

- the resolution specified in the "target resolution" setting in the

- <a href="configuration.html">configuration</a> if SVG filters are applied. This can be

- used as a work-around to resample images in FO documents.

- </p>

- </section>

- <section id="page-selection">

- <title>Page selection for multi-page formats</title>

- <p>

- Some image formats such as TIFF support multiple pages/sub-images per file. You can

- select a particular page using a special URI fragment in the form:

- &lt;uri&gt;#page=&lt;nr&gt;

- (for example: <code>http://localhost/images/myimage.tiff#page=3</code>)

- </p>

- </section>

- <section id="caching">

- <title>Image caching</title>

- <p>

- FOP caches images between runs. There is one cache per FopFactory instance. The URI is

- used as a key to identify images which means that when a particular URI appears again,

- the image is taken from the cache. If you have a servlet that generates a different

- image each time it is called with the same URI you need to use a constantly

- changing dummy parameter on the URI to avoid caching.

- </p>

- <p>

- The image cache has been improved considerably in the redesigned code. Therefore,

- resetting the image cache should be a thing of the past. If you

- still experience OutOfMemoryErrors, please notify us.

- </p>

- <p>

- If all else fails, the image cache can be cleared like this:

- <code>fopFactory.getImageManager().getCache().clearCache();</code>

- <title>Hyphenation Support</title>

- <section id="intro">

- <title>Introduction</title>

- <p>Apache™ FOP uses Liang's hyphenation algorithm, well known from TeX. It needs

- language specific pattern and other data for operation.</p>

- <p>Because of <a href="#license-issues">licensing issues</a> (and for

- convenience), all hyphenation patterns for FOP are made available through

- the <a class="fork" href="http://offo.sourceforge.net/hyphenation/index.html">Objects For

- Formatting Objects</a> project.</p>

- <note>If you have made improvements to an existing FOP hyphenation pattern,

- or if you have created one from scratch, please consider contributing these

- to OFFO so that they can benefit other FOP users as well.

- Please inquire on the <a href="../maillist.html#fop-user">FOP User

- mailing list</a>.</note>

- </section>

- <section id="license-issues">

- <title>License Issues</title>

- <p>Many of the hyphenation files distributed with TeX and its offspring are

- licenced under the <a class="fork" href="http://www.latex-project.org/lppl.html">LaTeX

- Project Public License (LPPL)</a>, which prevents them from being

- distributed with Apache software. The LPPL puts restrictions on file names

- in redistributed derived works which we feel can't guarantee. Some

- hyphenation pattern files have other or additional restrictions, for

- example against use for commercial purposes.</p>

- <p>Although Apache FOP cannot redistribute hyphenation pattern files that do

- not conform with its license scheme, that does not necessarily prevent users

- from using such hyphenation patterns with FOP. However, it does place on

- the user the responsibility for determining whether the user can rightly use

- such hyphenation patterns under the hyphenation pattern license.</p>

- <warning>The user is responsible to settle license issues for hyphenation

- pattern files that are obtained from non-Apache sources.</warning>

- </section>

- <section id="sources">

- <title>Sources of Custom Hyphenation Pattern Files</title>

- <p>The most important source of hyphenation pattern files is the

- <a class="fork" href="http://www.ctan.org/tex-archive/language/hyphenation/">CTAN TeX

- Archive</a>.</p>

- </section>

- <section id="install">

- <title>Installing Custom Hyphenation Patterns</title>

- <p>To install a custom hyphenation pattern for use with FOP:</p>

- <ol>

- <li>Convert the TeX hyphenation pattern file to the FOP format. The FOP

- format is an xml file conforming to the DTD found at

- <code>{fop-dir}/hyph/hyphenation.dtd</code>.</li>

- <li>Name this new file following this schema:

- <code>languageCode_countryCode.xml</code>. The country code is

- optional, and should be used only if needed. For example:

- <ul>

- <li><code>en_US.xml</code> would be the file name for American

- English hyphenation patterns.</li>

- <li><code>it.xml</code> would be the file name for Italian

- hyphenation patterns.</li>

- </ul>

- The language and country codes must match the XSL-FO input, which

- follows <a href="http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt">ISO

- 639</a> (languages) and <a href="http://www.ics.uci.edu/pub/ietf/http/related/iso3166.txt">ISO

- 3166</a> (countries). NOTE: The ISO 639/ISO 3166 convention is that

- language names are written in lower case, while country codes are written

- in upper case. FOP does not check whether the language and country specified

- in the FO source are actually from the current standard, but it relies

- on it being two letter strings in a few places. So you can make up your

- own codes for custom hyphenation patterns, but they should be two

- letter strings too (patches for proper handling extensions are welcome)</li>

- <li>There are basically three ways to make the FOP-compatible hyphenation pattern

- file(s) accessible to FOP:

- <ul>

- <li>Download the precompiled JAR from <a class="fork" href="http://offo.sourceforge.net/hyphenation/index.html">OFFO

- </a> and place it either in the <code>{fop-dir}/lib</code> directory, or

- in a directory of your choice (and append the full path to the JAR to

- the environment variable <code>FOP_HYPHENATION_PATH</code>).</li>

- <li>Download the desired FOP-compatible hyphenation pattern file(s) from

- <a class="fork" href="http://offo.sourceforge.net/hyphenation/index.html">OFFO</a>,

- and/or take your self created hyphenation pattern file(s),

- <ul>

- <li>place them in the directory <code>{fop-dir}/hyph</code>, </li>

- <li>or place them in a directory of your choice and set the Ant variable

- <code>user.hyph.dir</code> to point to that directory (in

- <code>build-local.properties</code>),</li>

- </ul>

- and run Ant with build target

- <code>jar-hyphenation</code>. This will create a JAR containing the

- compiled patterns in <code>{fop-dir}/build</code> that will be added to the

- classpath on the next run.

- (When FOP is built from scratch, and there are pattern source file(s)

- present in the directory pointed to by the

- <code>user.hyph.dir</code> variable, this JAR will automatically

- be created from the supplied pattern(s)).</li>

- <li>Put the pattern source file(s) into a directory of your choice and

- configure FOP to look for custom patterns in this directory, by setting the

- <a href="configuration.html">&lt;hyphenation-base&gt;</a>

- configuration option.</li>

- </ul>

- </li>

- </ol>

- Either of these three options will ensure hyphenation is working when using

- <title>Hyphenation Patterns</title>

- <p>If you would like to build your own hyphenation pattern files, or modify

- existing ones, this section will help you understand how to do so. Even

- when creating a pattern file from scratch, it may be beneficial to start

- with an existing file and modify it. See <a class="fork" href="http://offo.sourceforge.net/hyphenation/index.html">

- OFFO's Hyphenation page</a> for examples.

- Here is a brief explanation of the contents of FOP's hyphenation patterns:</p>

- <warning>The remaining content of this section should be considered "draft"

- quality. It was drafted from theoretical literature, and has not been

- tested against actual FOP behavior. It may contain errors or omissions.

- Do not rely on these instructions without testing everything stated here.

- If you use these instructions, please provide feedback on the

- <a href="../maillist.html#fop-user">FOP User mailing list</a>, either

- confirming their accuracy, or raising specific problems that we can

- address.</warning>

- <ul>

- <li>The root of the pattern file is the &lt;hyphenation-info&gt; element.</li>

- <li>&lt;hyphen-char&gt;: its attribute "value" contains the character signalling

- a hyphen in the &lt;exceptions&gt; section. It has nothing to do with the

- hyphenation character used in FOP, use the XSLFO hyphenation-character

- property for defining the hyphenation character there. At some points

- a dash U+002D is hardwired in the code, so you'd better use this too

- (patches to rectify the situation are welcome). There is no default,

- if you declare exceptions with hyphenations, you must declare the

- hyphen-char too.</li>

- <li>&lt;hyphen-min&gt; contains two attributes:

- <ul>

- <li>before: the minimum number of characters in a word allowed to exist

- on a line immediately preceding a hyphenated word-break.</li>

- <li>after: the minimum number of characters in a word allowed to exist

- on a line immediately after a hyphenated word-break.</li>

- </ul>

- This element is unused and not even read. It should be considered a

- documentation for parameters used during pattern generation.

- </li>

- <li>&lt;classes&gt; contains whitespace-separated character sets. The members

- of each set should be treated as equivalent for purposes of hyphenation,

- usually upper and lower case of the same character. The first character

- of the set is the canonical character, the patterns and exceptions

- should only contain these canonical representation characters (except

- digits for weight, the period (.) as word delimiter in the patterns and

- the hyphen char in exceptions, of course).</li>

- <li>&lt;exceptions&gt; contains whitespace-separated words, each of which

- has either explicit hyphen characters to denote acceptable breakage

- points, or no hyphen characters, to indicate that this word should

- never be hyphenated, or contain explicit &lt;hyp&gt; elements for specifying

- changes of spelling due to hyphenation (like backen -&gt; bak-ken or

- Stoffarbe -&gt; Stoff-farbe in the old german spelling). Exceptions override

- the patterns described below. Explicit &lt;hyp&gt; declarations don't work

- yet (patches welcome). Exceptions are generally a bit brittle, test

- carefully.</li>

- <li>&lt;patterns&gt; includes whitespace-separated patterns, which are what

- drive most hyphenation decisions. The characters in these patterns are

- explained as follows:

- <ul>

- <li>non-numeric characters represent characters in a sub-word to be

- evaluated</li>

- <li>the period character (.) represents a word boundary, i.e. either

- the beginning or ending of a word</li>

- <li>numeric characters represent a scoring system for indicating the

- acceptability of a hyphen in this location. Odd numbers represent an

- acceptable location for a hyphen, with higher values overriding lower

- inhibiting values. Even numbers indicate an unacceptable location, with

- higher values overriding lower values indicating an acceptable position.

- A value of zero (inhibiting) is implied when there is no number present.

- Generally patterns are constructed so that valuse greater than 4 are rare.

- Due to a bug currently patterns with values of 8 and greater don't

- have an effect, so don't wonder.</li>

- </ul>

- Here are some examples from the English patterns file:

- <ul>

- <li>Knuth (<em>The TeXBook</em>, Appendix H) uses the example <strong>hach4</strong>, which indicates that it is extremely undesirable to place a hyphen after the substring "hach", for example in the word "toothach-es".</li>

- <li><strong>.leg5e</strong> indicates that "leg-e", when it occurs at the beginning of a word, is a very good place to place a hyphen, if one is needed. Words like "leg-end" and "leg-er-de-main" fit this pattern.</li>

- </ul>

- Note that the algorithm that uses this data searches for each of the word's substrings in the patterns, and chooses the <em>highest</em> value found for letter combination.

- </li>

- </ul>

- <p>If you want to convert a TeX hyphenation pattern file, you have to undo

- the TeX encoding for non-ASCII text. FOP uses Unicode, and the patterns

- must be proper Unicode too. You should be aware of the XML encoding issues,

- preferably use a good Unicode editor.</p>

- <p>Note that FOP does not do Unicode character normalization. If you use

- combining chars for accents and other character decorations, you must

- declare character classes for them, and use the same sequence of base character

- and combining marks in the XSLFO source, otherwise the pattern wouldn't match.

- Fortunately, Unicode provides precomposed characters for all important cases

- in common languages, until now nobody run seriously into this issue. Some dead

- languages and dialects, especially ancient ones, may pose a real problem

- though.</p>

- <p>If you want to generate your own patterns, an open-source utility called

- patgen is available on many Unix/Linux distributions and every TeX

- distribution which can be used to assist in

- creating pattern files from dictionaries. Pattern creation for languages like

- english or german is an art. If you can, read Frank Liang's original paper

- "Word Hy-phen-a-tion by Com-pu-ter" (yes, with hyphens). It is not available

- online. The original patgen.web source, included in the TeX source distributions,

- contains valuable comments, unfortunately technical details obscure often the

- high level issues. Another important source is

- <a class="fork" href="http://www.ctan.org/tex-archive/systems/knuth/tex/texbook.tex">The

- TeX Book</a>, appendix H (either read the TeX source, or run it through

- TeX to typeset it). Secondary articles, for example the works by Petr Sojka,

- may also give some much needed insight into problems arising in automated

- hyphenation.</p>

- <title>Apache™ FOP: Intermediate Format</title>

- <version>$Revision$</version>

- </header>

- <body>

- <note>

- Please note that the intermediate format is an <strong>advanced feature</strong> and can be ignored by most

- users of Apache™ FOP.

- </note>

- <section id="introduction">

- <title>Introduction</title>

- <p>

- The intermediate format (IF) is a proprietary XML format that represents the area tree

- generated by the layout engine. The area tree is conceptually defined in the

- <a href="http://www.w3.org/TR/2001/REC-xsl-20011015/slice1.html#section-N742-Formatting">XSL-FO specification in chapter 1.1.2</a>.

- The IF can be generated through the area tree XML Renderer (the XMLRenderer).

- </p>

- <p>

- The intermediate format can be used to generate intermediate documents that are modified

- before they are finally rendered to their ultimate output format. Modifications include

- adjusting and changing trait values, adding or modifying area objects, inserting prefabricated

- pages, overlays, imposition (n-up, rotation, scaling etc.). Multiple IF files can be combined

- to a single output file.

- </p>

- </section>

- <section id="usage">

- <title>Usage of the Intermediate Format</title>

- <p>

- As already mentioned, the IF is generated by using the <strong>XMLRenderer</strong> (MIME type:

- <strong>application/X-fop-areatree</strong>). So, you basically set the right MIME type for

- the output format and process your FO files as if you would create a PDF file. However, there

- is an important detail to consider: The various Renderers don't all use the same font sources.

- To be able to create the right area tree for the ultimate output file, you need to create

- the IF file using the right font setup. This is achieved by telling the XMLRenderer to mimic

- another renderer. This is done by calling the XMLRenderer's mimicRenderer() method with an

- instance of the ultimate target renderer as the single parameter. This has a consequence: An

- IF file rendered with the Java2DRenderer may not look as expected when it was actually generated

- for the PDF renderer. For renderers that use the same font setup, this restriction does not

- apply (PDF and PS, for example). Generating the intermediate format file is the first step.

- </p>

- <p>

- The second step is to reparse the IF file using the <strong>AreaTreeParser</strong> which is

- found in the org.apache.fop.area package. The pages retrieved from the IF file are added to an

- AreaTreeModel instance from where they are normally rendered using one of the available Renderer

- implementations. You can find examples for the IF processing in the

- <a href="http://svn.apache.org/viewcvs.cgi/xmlgraphics/fop/trunk/examples/embedding/java/embedding/intermediate/"><code>examples/embedding</code></a>

- directory in the FOP distribution

- </p>

- <p>

- The basic pattern to parse the IF format looks like this:

- </p>

- <source><![CDATA[

-FopFactory fopFactory = FopFactory.newInstance();

-

-// Setup output

-OutputStream out = new java.io.FileOutputStream(pdffile);

-out = new java.io.BufferedOutputStream(out);

-try {

- //Setup fonts and user agent

- FontInfo fontInfo = new FontInfo();

- FOUserAgent userAgent = fopFactory.newFOUserAgent();

-

- //Construct the AreaTreeModel that will received the individual pages

- AreaTreeModel treeModel = new RenderPagesModel(userAgent,

- MimeConstants.MIME_PDF, fontInfo, out);

-

- //Parse the IF file into the area tree

- AreaTreeParser parser = new AreaTreeParser();

- Source src = new StreamSource(myIFFile);

- parser.parse(src, treeModel, userAgent);

-

- //Signal the end of the processing. The renderer can finalize the target document.

- treeModel.endDocument();

-} finally {

- out.close();

-}]]></source>

- <p>

- This example simply reads an IF file and renders it to a PDF file. Please note, that in normal

- FOP operation you're shielded from having to instantiate the FontInfo object yourself. This

- is normally a task of the AreaTreeHandler which is not present in this scenario. The same

- applies to the AreaTreeModel instance, in this case an instance of a subclass called

- RenderPagesModel. RenderPagesModel is ideal in this case as it has very little overhead

- processing the individual pages. An important line in the example is the call to

- <code>endDocument()</code> on the AreaTreeModel. This lets the Renderer know that the processing

- is now finished.

- </p>

- <p>

- The intermediate format can also be used from the <a href="running.html#standalone-start">command-line</a>

- by using the "-atin" parameter for specifying the area tree XML as input file. You can also

- specify a "mimic renderer" by inserting a MIME type between "-at" and the output file.

- </p>

- <section id="concat">

- <title>Concatenating Documents</title>

- <p>

- This initial example is obviously not very useful. It would be faster to create the PDF file

- directly. As the <a href="http://svn.apache.org/repos/asf/xmlgraphics/fop/trunk/examples/embedding/java/embedding/intermediate/ExampleConcat.java">ExampleConcat.java</a>

- example shows you can easily parse multiple IF files in a row and add the parsed pages to the

- same AreaTreeModel instance which essentially concatenates all the input document to one single

- output document.

- </p>

- </section>

- <section id="modifying">

- <title>Modifying Documents</title>

- <p>

- One of the most important use cases for the intermediate format is obviously modifying the area

- tree XML before finally rendering it to the target format. You can easily use XSLT to process

- the IF file according to your needs. Please note, that we will currently not formally describe

- the intermediate format. You need to have a good understanding its structure so you don't

- create any non-parseable files. We may add an XML Schema and more detailed documentation at a

- later time. You're invited to help us with that.

- </p>

- </section>

- <section id="advanced">

- <title>Advanced Use</title>

- <p>

- The generation of the intermediate format as well as it parsing process has been designed to allow

- for maximum flexibility and optimization. Please note that you can call <code>setTransformerHandler()</code> on

- XMLRenderer to give the XMLRenderer your own TransformerHandler instance in case you would like to

- do custom serialization (to a W3C DOM, for example) and/or to directly modify the area tree using

- XSLT. The AreaTreeParser on the other side allows you to retrieve a ContentHandler instance where

- you can manually send SAX events to to start the parsing process (see <code>getContentHandler()</code>).

- <title>Overview</title>

- <p>

- Document metadata is an important tool for categorizing and finding documents.

- Various formats support different kinds of metadata representation and to

- different levels. One of the more popular and flexible means of representing

- document or object metadata is

- <a href="http://www.adobe.com/products/xmp/">XMP (eXtensible Metadata Platform, specified by Adobe)</a>.

- PDF 1.4 introduced the use of XMP. The XMP specification lists recommendation for

- embedding XMP metdata in other document and image formats. Given its flexibility it makes

- sense to make use this approach in the XSL-FO context. Unfortunately, unlike SVG which

- also refers to XMP, XSL-FO doesn't recommend a preferred way of specifying document and

- object metadata. Therefore, there's no portable way to represent metadata in XSL-FO

- documents. Each implementation does it differently.

- </p>

- </section>

- <section id="xmp-in-fo">

- <title>Embedding XMP in an XSL-FO document</title>

- <p>

- As noted above, there's no officially recommended way to embed metadata in XSL-FO.

- Apache™ FOP supports embedding XMP in XSL-FO. Currently, only support for document-level

- metadata is implemented. Object-level metadata will be implemented when there's

- interest.

- </p>

- <p>

- Document-level metadata can be specified in the <code>fo:declarations</code> element.

- XMP specification recommends to use <code>x:xmpmeta</code>, <code>rdf:RDF</code>, and

- <code>rdf:Description</code> elements as shown in example below. Both

- <code>x:xmpmeta</code> and <code>rdf:RDF</code> elements are recognized as the top-level

- element introducing an XMP fragment (as per the XMP specification).

- <title>Implementation in Apache FOP</title>

- <p>

- Currently, XMP support is only available for PDF output.

- </p>

- <p>

- Originally, you could set some metadata information through FOP's FOUserAgent by

- using its set*() methods (like setTitle(String) or setAuthor(String). These values are

- directly used to set value in the PDF Info object. Since PDF 1.4, adding metadata as an

- XMP document to a PDF is possible. That means that there are now two mechanisms in PDF

- that hold metadata.

- </p>

- <p>

- Apache FOP now synchronizes the Info and the Metadata object in PDF, i.e. when you

- set the title and the author through the FOUserAgent, the two values will end up in

- the (old) Info object and in the new Metadata object as XMP content. If instead of

- FOUserAgent, you embed XMP metadata in the XSL-FO document (as shown above), the

- XMP metadata will be used as-is in the PDF Metadata object and some values from the

- XMP metadata will be copied to the Info object to maintain backwards-compatibility

- for PDF readers that don't support XMP metadata.

- </p>

- <p>

- The mapping between the Info and the Metadata object used by Apache FOP comes from

- the <a href="http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=38920">PDF/A-1 specification</a>.

- For convenience, here's the mapping table:

- </p>

- this was changed to map to <code>dc:description["x-default"]</code>.

- <section id="namespaces">

- <title>Namespaces</title>

- <p>

- Metadata is made of property sets where each property set uses a different namespace URI.

- </p>

- <p>

- The following is a listing of namespaces that Apache FOP recognizes and acts upon,

- mostly to synchronize the XMP metadata with the PDF Info dictionary:

- <body>

- <p>

- Apache™ FOP supports multiple output formats by using a different renderer for each format.

- The renderers do not all have the same set of capabilities, sometimes because of

- the output format itself, sometimes because some renderers get more development

- attention than others.

- </p>

- <section id="general">

- <title>General Information</title>

- <section id="general-fonts">

- <title>Fonts</title>

- <p>

- Most FOP renderers use a FOP-specific system for font registration.

- However, the Java2D/AWT and print renderers use the Java AWT package, which gets its

- font information from the operating system registration.

- This can result in several differences, including actually using different fonts,

- and having different font metrics for the same font.

- The net effect is that the layout of a given FO document can be quite different between

- renderers that do not use the same font information.

- </p>

- <p>

- Theoretically, there's some potential to make the output of the PDF/PS renderers match

- the output of the Java2D-based renderers. If FOP used the font metrics from its own

- font subsystem but still used Java2D for text painting in the Java2D-based renderers,

- this could probably be achieved. However, this approach hasn't been implemented, yet.

- </p>

- <p>

- With a work-around, it is possible to match the PDF/PS output in a Java2D-based

- renderer pretty closely. The clue is to use the

- <a href="intermediate.html">intermediate format</a>. The trick is to layout the

- document using FOP's own font subsystem but then render the document using Java2D.

- Here are the necessary steps (using the command-line):

- </p>

- <ol>

- <li>

- Produce an IF file: <code>fop -fo myfile.fo -at application/pdf myfile.at.xml</code><br/>

- Specifying "application/pdf" for the "-at" parameter causes FOP to use FOP's own

- font subsystem (which is used by the PDF renderer). Note that no PDF file is created

- in this step.

- </li>

- <li>Render to a PDF file: <code>fop -atin myfile.at.xml -pdf myfile.pdf</code></li>

- <li>Render to a Java2D-based renderer:

- <ul>

- <li><code>fop -atin myfile.at.xml -print</code></li>

- <li><code>fop -atin myfile.at.xml -awt</code></li>

- <li><code>fop -atin myfile.at.xml -tiff myfile.tiff</code></li>

- </ul>

- </li>

- </ol>

- </section>

- <section id="general-direct-output">

- <title>Output to a Printer or Other Device</title>

- <p>

- The most obvious way to print your document is to use the FOP

- <a href="#print">print renderer</a>, which uses the Java2D API (AWT).

- However, you can also send output from the Postscript renderer directly to a Postscript

- device, or output from the PCL renderer directly to a PCL device.

- </p>

- <p>

- Here are Windows command-line examples for Postscript and PCL:

- </p>

- <source><![CDATA[fop ... -ps \\computername\printer]]></source>

- <source><![CDATA[fop ... -pcl \\computername\printer]]></source>

- <p>

- Here is some Java code to accomplish the task in UNIX:

- </p>

- <source><![CDATA[proc = Runtime.getRuntime().exec("lp -d" + print_queue + " -o -dp -");

-out = proc.getOutputStream();]]></source>

- <p>

- Set the output MIME type to "application/x-pcl" (MimeConstants.MIME_PCL) and

- it happily sends the PCL to the UNIX printer queue.

- </p>

- </section>

- </section>

- <section id="pdf">

- <title>PDF</title>

- <p>

- PDF is the best supported output format. It is also the most accurate

- with text and layout. This creates a PDF document that is streamed out

- as each page is rendered. This means that the internal page index

- information is stored near the end of the document.

- The PDF version supported is 1.4. PDF versions are forwards/backwards

- compatible.

- </p>

- <p>

- Note that FOP does not currently support "tagged PDF" or PDF/A-1a.

- Support for <a href="pdfa.html">PDF/A-1b</a> and <a

- href="pdfx.html">PDF/X</a> has recently been added, however.

- </p>

- <section id="pdf-fonts">

- <title>Fonts</title>

- <p>

- PDF has a set of fonts that are always available to all PDF viewers;

- to quote from the PDF Specification:

-

- <em>"PDF prescribes a set of 14 standard fonts that can be used without prior

- definition.

- These include four faces each of three Latin text typefaces (Courier,

- Helvetica, and Times), as well as two symbolic fonts (Symbol and ITC Zapf

- Dingbats). These fonts, or suitable substitute fonts with the same metrics, are

- guaranteed to be available in all PDF viewer applications."</em>

- </p>

- </section>

- <section id="pdf-postprocess">

- <title>Post-processing</title>

- <p>

- FOP does not currently support several desirable PDF features: watermarks and signatures.

- One workaround is to use Adobe Acrobat (the full version, not the Reader) to process

- the file manually or with scripting that it supports.

- </p>

- <p>

- Another popular post-processing tool is <a href="http://www.lowagie.com/iText">iText</a>,

- which has tools for adding security features, document properties, watermarks, and many

- other features to PDF files.

- </p>

- <warning>

- Caveat: iText may swallow PDF bookmarks. But

- <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=37589">Jens Stavnstrup tells us</a>

- that this doesn't happen if you use iText's PDFStamper.

- </warning>

- <p>

- Here is some sample code that uses iText to encrypt a FOP-generated PDF. (Note that FOP now

- supports <a href="pdfencryption.html">PDF encryption</a>. However the principles for using

- iText for other PDF features are similar.)

- <title>PostScript</title>

- <p>

- The PostScript renderer has been brought up to a similar quality as the

- support for most text and layout.

- Images and SVG are not fully supported, yet. Currently, the PostScript

- renderer generates PostScript Level 3 with most DSC comments. Actually,

- the only Level 3 features used are the FlateDecode and DCTDecode

- filter (the latter is used for 1:1 embedding of JPEG images), everything

- else is Level 2.

- </p>

- <section id="ps-configuration">

- <title>Configuration</title>

- <p>

- The PostScript renderer configuration currently allows the following settings:

- </p>

-<source><![CDATA[<renderer mime="application/postscript">

- <auto-rotate-landscape>false</auto-rotate-landscape>

- <language-level>3</language-level>

- <optimize-resources>false</optimize-resources>

- <safe-set-page-device>false</safe-set-page-device>

- <dsc-compliant>true</dsc-compliant>

-</renderer>]]></source>

- <p>

- The default value for the "auto-rotate-landscape" setting is "false". Setting it

- to "true" will automatically rotate landscape pages and will mark them as landscape.

- </p>

- <p>

- The default value for the "language-level" setting is "3". This setting specifies

- the PostScript language level which should be used by FOP. Set this to "2"

- only if you don't have a Level 3 capable interpreter.

- </p>

- <p>

- The default value for the "optimize-resources" setting is "false". Setting it

- to "true" will produce the PostScript file in two steps. A temporary file will be

- written first which will then be processed to add only the fonts which were really

- used and images are added to the stream only once as PostScript forms. This will

- reduce file size but can potentially increase the memory needed in the interpreter

- to process.

- </p>

- <p>

- The default value for the "safe-set-page-device" setting is "false". Setting it

- to "true" will cause the renderer to invoke a postscript macro which guards against

- the possibility of invalid/unsupported postscript key/values being issued to the

- implementing postscript page device.

- </p>

- <p>

- The default value for the "dsc-compliant" setting is "true". Setting it

- to "false" will break DSC compliance by minimizing the number of setpagedevice

- calls in the postscript document output. This feature may be useful when unwanted

- blank pages are experienced in your postscript output. This problem is caused by

- the particular postscript implementation issuing unwanted postscript subsystem

- initgraphics/erasepage calls on each setpagedevice call.

- <title>PCL</title>

- <p>

- This format is for the Hewlett-Packard PCL printers and other printers

- supporting PCL. It should produce output as close to identical as possible

- to the printed output of the PDFRenderer within the limitations of the

- renderer, and output device.

- </p>

- <p>

- The output created by the PCLRenderer is generic PCL 5, HP GL/2 and PJL.

- This should allow any device fully supporting PCL 5 to be able to

- print the output generated by the PCLRenderer. PJL is used to control the

- print job and switch to the PCL language. PCL 5 is used for text, raster

- graphics and rectangular fill graphics. HP GL/2 is used for more complex

- painting operations. Certain painting operations are done off-screen and

- rendered to PCL as bitmaps because of limitations in PCL 5.

- <title>Limitations</title>

- <ul>

- <li>

- Text or graphics outside the left or top of the printable area are not

- rendered properly. This is a limitation of PCL, not FOP. In general,

- things that should print to the left of the printable area are shifted

- to the right so that they start at the left edge of the printable area.

- </li>

- <li>

- The Helvetica and Times fonts are not well supported among PCL printers

- so Helvetica is mapped to Arial and Times is mapped to Times New. This

- is done in the PCLRenderer, no changes are required in the FO's. The

- metrics and appearance for Helvetica/Arial and Times/Times New are

- nearly identical, so this has not been a problem so far.

- </li>

- <li>For the non-symbol fonts, the ISO 8859-1 symbol set is used (PCL set "0N").</li>

- <li>

- All fonts available to the Java2D subsystem are usable. The texts are

- painted as bitmap much like the Windows PCL drivers do.

- </li>

- <li>Multibyte characters are not supported.</li>

- <li>

- At the moment, only monochrome output is supported. PCL5c color extensions

- will only be implemented on demand. Color and grayscale images are converted

- to monochrome bitmaps (1-bit). Dithering only occurs if the JAI image library

- is available.

- </li>

- <li>

- Images are scaled up to the next resolution level supported by PCL (75,

- 100, 150, 200, 300, 600 dpi). For color and grayscale images an even

- higher PCL resolution is selected to give the dithering algorithm a chance

- to improve the bitmap quality.

- </li>

- <li>

- Currently, there's no support for clipping and image transparency, largely

- because PCL 5 has certain limitations.

- </li>

- </ul>

- <section id="pcl-configuration">

- <title>Configuration</title>

- <p>

- The PCL renderer configuration currently allows the following settings:

- </p>

-<source><![CDATA[<renderer mime="application/vnd.hp-PCL">

- <rendering>quality</rendering>

- <text-rendering>bitmap</text-rendering>

- <disable-pjl>false</disable-pjl>

-</renderer>]]></source>

- <p>

- The default value for the "rendering" setting is "speed" which causes borders

- to be painted as plain rectangles. In this mode, no special borders (dotted,

- dashed etc.) are available. If you want support for all border modes, set the

- value to "quality" as indicated above. This will cause the borders to be painted

- as bitmaps.

- </p>

- <p>

- The default value for the "text-rendering" setting is "auto" which paints the

- base fonts using PCL fonts. Non-base fonts are painted as bitmaps through Java2D.

- If the mix of painting methods results in unwelcome output, you can set this

- to "bitmap" which causes all text to be rendered as bitmaps.

- </p>

- <p>

- The default value for the "disable-pjl" setting is "false". This means that

- the PCL renderer usually generates PJL commands before and after the document

- in order to switch a printer into PCL language. PJL commands can be disabled

- if you set this value to "true".

- </p>

- <p>

- You can control the output resolution for the PCL using the "target resolution"

- setting on the FOUserAgent. The actual value will be rounded up to the next

- supported PCL resolution. Currently, only 300 and 600 dpi are supported which

- should be enough for most use cases. Note that this setting directly affects

- the size of the output file and the print quality.

- </p>

- </section>

- <section id="pcl-extensions">

- <title>Extensions</title>

- <p>The PCL Renderer supports some PCL specific extensions which can be embedded

- into the input FO document. To use the extensions the appropriate namespace must

- be declared in the fo:root element like this:</p>

- <source><![CDATA[

- <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format"

- xmlns:pcl="http://xmlgraphics.apache.org/fop/extensions/pcl">

-]]></source>

- <section id="pcl-page-source">

- <title>Page Source (Tray selection)</title>

- <p>

- The page-source extension attribute on fo:simple-page-master allows to

- select the paper tray the sheet for a particular simple-page-master is

- to be taken from. Example:

- </p>

- <source><![CDATA[

- <fo:layout-master-set>

- <fo:simple-page-master master-name="simple" pcl:paper-source="2">

- ...

- </fo:simple-page-master>

- </fo:layout-master-set>

-]]></source>

- <p>

- Note: the tray number is a positive integer and the value depends on

- the target printer. Not all PCL printers support the same paper trays.

- Usually,

- "1" is the default tray,

- "2" is the manual paper feed,

- "3" is the manual envelope feed,

- "4" is the "lower" tray and

- "7" is "auto-select".

- Consult the technical reference for your printer for all available values.

- <title>Fonts</title>

- <p>The AFP Renderer requires special configuration particularly related to fonts.

- AFP Render configuration is done through the normal FOP configuration file. The MIME type

- for the AFP Renderer is application/x-afp which means the AFP Renderer section in the FOP configuration file

- looks like:</p>

- <source><![CDATA[<renderer mime="application/x-afp">

- <!-- AFP Renderer -->

- ...

-</renderer>]]></source>

- <p>There are 3 font configuration variants supported:</p>

- <ol>

- <li>IBM Raster fonts</li>

- <li>IBM Outline fonts</li>

- <li>FOP built-in Base14 fonts</li>

- </ol>

- <p>A typical raster font configuration looks like:</p>

-<source><![CDATA[ <!-- This is an example of mapping actual IBM raster fonts / code pages to a FOP font -->

- <font>

- </font>]]></source>

- <p>An outline font configuration is simpler as the individual font size entries are not required.

- However, the characterset definition is now required within the afp-font element.</p>

-<source><![CDATA[ <font>

- <afp-font type="outline" codepage="T1V10500" encoding="Cp500" characterset="CZH200 "

- <font-triplet name="any" style="normal" weight="normal"/>

- </font>

-]]></source>

- <p>Experimentation has shown that the font metrics for the FOP built-in Base14 fonts are actually

- very similar to some of the IBM outline and raster fonts. In cases were the IBM font files are not

- available the path attribute in the afp-font element can be replaced by a base14-font attribute

- giving the name of the matching Base14 font. In this case the AFP Renderer will take the

- font metrics from the built-in font.</p>
