'''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 [[Portable Document Format|PDF]] or other printable formats.<br />
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.<br />
<br />
FOP is [[open source software]], and is distributed under the [[Apache License 2.0]].<br />
<br />
==Current status==<br />
The latest version of Apache FOP is 2.11.<ref>{{cite web|url=https://xmlgraphics.apache.org/fop/status.html|title=Apache FOP Status}}</ref> <br />
<br />
==Major limitations==<br />
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.html|title=Apache FOP XSL-FO Compliance}}</ref><br />
<br />
In addition, older XSL-FO 1.0 features are still not fully supported including automatic table layout, floats and more.<br />
<br />
==Input support==<br />
Apache FOP supports embedding a number of image formats in the XSL-FO (through the <code><fo:external-graphic></code> element). These include:<br />
<br />
* [[Scalable Vector Graphics|SVG]]<br />
* [[Portable Network Graphics|PNG]]<br />
* Bitmap [[BMP file format|BMP]]<br />
* [[PostScript]] (as EPS)<br />
* [[JPEG]]<br />
* Some [[TIFF]] formats.<br />
<br />
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.<br />
<br />
==Output formats==<br />
Apache FOP supports the following output formats:<br />
<br />
* [[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><br />
* [[ASCII]] text file facsimile<br />
* [[PostScript]]<br />
* Direct printer output ([[Printer Control Language|PCL]])<br />
* [[Advanced Function Presentation|AFP]]<br />
* [[Rich Text Format|RTF]]<br />
* [[Java2D]]/[[Abstract Window Toolkit|AWT]] for display, printing, and page rendering to [[Portable Network Graphics|PNG]] and [[Tagged Image File Format|TIFF]]<br />
<br />
In progress:<br />
*[[Maker Interchange Format|MIF]]<br />
*[[Scalable Vector Graphics|SVG]]<br />
