Formatting Objects Processor (FOP, also known as Apache FOP) is a 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 Apache License 2.0.

Current statusEdit

The latest version of Apache FOP is 2.10.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> This is the seventeenth stable release.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Major limitationsEdit

Most important elements added in XSL-FO 1.1 (flow maps, table markers, indexes. etc.) are not available <ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

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

Input supportEdit

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

SVG
PNG
Bitmap BMP
PostScript (as EPS)
JPEG
Some TIFF formats.

Apache FOP implements the <fo:float> element with some limitations.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In versions prior to 2.0, external graphics objects were limited to being drawn inline or in a block with no wrapped text.
