Hi Georg No, we haven't documented the area tree format explicitely. I guess we assume that for people going that deep into FOP the source code is enough documentation. At any rate, there's no lack of examples once you've run the whole test suite once. ;-)
What we have is some documentation on how to create layout engine tests: http://wiki.apache.org/xmlgraphics-fop/HowToCreateLayoutEngineTests On 09.01.2009 12:41:53 Georg Datterl wrote: > Hi Vincent, hi Jeremias, > > I made one single minor mistake and 49 tests complained...
