<!-- Overview -->
<s1 title="Fop">
<s2 title="What is FOP?">
<p>FOP is the world's first print formatter driven by XSL formatting
objects. It is a Java application that reads a formatting object
tree and then turns it into a PDF document. The formatting object
tree, can be in the form of an XML document (output by an XSLT engine
like XT or Xalan) or can be passed in memory as a DOM Document or (in
the case of XT) SAX events.
</p>
<p>The latest version of Fop is 0.15 and it supports the xsl:fo candidate release.
You can <jump href="download.html">download</jump>
Fop including a precompiled version, the source code and many example files to
get you started. Pointers to introductions into xsl:fo can be found in the
section <jump href="specs.html">specifications</jump>. Please be aware, that
Fop is at the moment not a full implementation of the basic conformance level
of the xsl:fo standard. You can find a list of supported flow objects and properties
in the section <jump href="implemented.html">Features</jump> and in section
<jump href="limitations.html">Limitations</jump> in what way this support is
limited.
</p>
<p>FOP is part of Apache's XML project. The homepage of FOP is
<jump href="http://xml.apache.org/fop">http://xml.apache.org/fop</jump>. A list
of known bugs, the committers to this project and the tasks they are working on can be found
in the file <jump href="http://xml.apache.org/websrc/cvsweb.cgi/xml-fop/">Status</jump> in the
root of your Fop distribution.
</p>
</s2>
<s2 title="FOP Objectives">
<p>The goals of the Apache XML FOP Project are to deliver an XSL FO->PDF formatter that is compliant to at least the Basic
conformance level described in the 27 March 2000 XSL WD, and that complies with the 11 March 1999 Portable Document
Format Specification (Version 1.3) from Adobe Systems.
</p>
<p>Conformance to the XML 1.0 Recommendation, XSLT 1.0 Recommendation and the XML Namespaces Recommendation is
understood. Other relevant documents, such as the XPath and XLink Working Drafts, are referenced as necessary. The FOP
Project will attempt to use the latest version of evolving specifications.
</p>
<p>Secondary goals of the FOP Project (also, "FOP") are desirable requirements that also have a high priority.
</p>
<p>One secondary goal of the FOP Project is to deliver a follow-on version of the formatter that is compliant to the Extended
conformance level described in the XSL FO. Any formatting objects that cannot be translated into PDF will be explicitly
identified as such.
</p>
<p>Another secondary goal is to promote the conversion of SVG into PDF. The most natural mechanism for doing so is within
fo:instream-foreign-object FO's. The powerful graphics offered by both SVG and PDF are a natural fit, and it is
desirable that FOP natively supports an SVG content processor for the fo:instream-foreign-object.
</p>
<p>A final secondary goal is the continued refinement of the FOP design and implementation. In particular, maintaining the
separation between formatting and rendering, continuing to support the AWT Viewer renderer (backend), and providing
new renderers, are all desirable objectives.
