'''Formatting Objects Processor''' ('''FOP''', also known as '''Apache FOP''') is a [[Java (programming language)|Java]] application that converts [[XSL Formatting Objects]] (XSL-FO) files to PDF or other printable formats.
FOP was originally developed by James Tauber who donated it to the Apache Software Foundation in 1999. It is part of the Apache XML Graphics project.

FOP is open source software, and is distributed under the [[Software:Apache License 2.0|Apache License 2.0]].

==Current status==
The latest version of Apache FOP is 2.9.<ref>{{cite web|url=https://xmlgraphics.apache.org/fop/status.html|title=Apache FOP Status}}</ref> This is the eleventh stable release.

==Major limitations==
Most important elements added in XSL-FO 1.1 (flow maps, table markers, indexes. etc.) are not available <ref>{{cite web|url=https://xmlgraphics.apache.org/fop/compliance-static.html|title=Apache FOP XSL-FO Compliance}}</ref>

In addition, older XSL-FO 1.0 features are still not fully supported including automatic table layout, floats and more.

==Input support==
Apache FOP supports embedding a number of image formats in the XSL-FO (through the <code><fo:external-graphic></code> element). These include:

* [[Scalable Vector Graphics|SVG]]
* [[Portable Network Graphics|PNG]]
* Bitmap BMP
* [[PostScript]] (as EPS)
* [[JPEG]]
* Some TIFF formats.

Apache FOP implements the <code><fo:float></code> element with some limitations.<ref>{{cite web |url=https://xmlgraphics.apache.org/fop/2.0/releaseNotes_2.0.html |title=Apache FOP 2.0 release notes |access-date=2015-12-18}}</ref> In versions prior to 2.0, external graphics objects were limited to being drawn inline or in a block with no wrapped text.

==Output formats==
Apache FOP supports the following output formats:

* [[PDF]] (best output support), including PDF/X and PDF/A with some limitations<ref>{{cite web |url=https://xmlgraphics.apache.org/fop/0.95/pdfx.html |title=FOP 0.95 - PDF/X (ISO 15930) |access-date=2011-05-22}}</ref>
* [[ASCII]] text file facsimile
* [[PostScript]]
* Direct printer output (PCL)
* [[Advanced Function Presentation|AFP]]
* [[Rich Text Format|RTF]]
* Java2D/[[Abstract Window Toolkit|AWT]] for display, printing, and page rendering to [[Portable Network Graphics|PNG]] and TIFF

In progress:
*MIF
*[[Scalable Vector Graphics|SVG]]
