Here we have some answers to common questions about FOP. This only covers general information about getting started with FOP and pointers to more information.

For up to date information or more details please visit the Fop FAQ site. The site uses Jyve to provide an interactive FAQ: http://www.OWAL.co.uk:8090/

FOP is a print formatter for XSL formatting objects.

It can be used to render an XML file containing XSL formatting objects into a page layout. The main target is PDF but other rendering targets are supported, such as AWT, PCL, text and direct printing.

FOP is distributed with Cocoon as a PDF serializer for XSL (FO) documents.

Batik can be used with FOP to transcode an SVG image into a PDF document. The mime type for PDF is "application/pdf".

XSL is an XML format that is used to specify a pagination and other styling for page layout output. XSL can be used in conjunction with XSLT to convert from any XML format into a paginated layout ready for printing or displaying.

XSL defines a set of formatting objects in xml that describes the way pages are set up. The contents of the pages are filled from flows which. There can be static flows that appear on every page and the main flow which fills the body of the page.

FOP is an application or library that converts an XSL FO document into the paginated output. It is possible to render the output to different targets, the main target is PDF. FOP can be run from the command line or embedded into your Java application.

The XSL FO can be delivered to FOP with XML(XSL FO), XML+XSL or SAX events.

There is always plenty of things to do.

Often XSL FO is created from XML and XSLT. There are some standard XML markups such as Docbook that can be converted into XSL FO and other XML formats.

There are some XSL authoring tools that may help you to author XSL FO documents or the XML and XSLT documents.

There will be a Java Webstart demo sometime in the future. This will use the AWT viewer to display FO documents.
