Current Status

The latest version of Apache FOP is 2.0. This is the fourth stable release and implements a large subset of the XSL-FO Version 1.1 W3C Recommendation. In version 0.95, the code had undergone a substantial rewrite compared to 0.20.5 which was the previous stable version. As of release 0.91alpha, FOP became much more compliant to the XSL-FO Recommendation.

Major Limitations

Most important elements added in XSL-FO 1.1 (flow maps, table markers, indexes. etc.) are not available [1]

In addition, older XSL-FO 1.0 features are still not 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 element). These include:

Apache FOP does not implement the element. External graphics objects are thus limited to being drawn inline or in a block with no wrapped text.

Output Formats

Apache FOP supports the following output formats:
