Speaking of extensions, I'd like to resurrect the layout extensions
That isn't exactly use of the term "extension" which I'm using and which
I think Jeremias is using in the ExtensionPoints wiki. Your extensions
are additional useful features, when I talk about extensions it is the
ability to dynamicly load additional behaviour without modifying FOP
sources.
If your features could be implemeted as dynamicly loaded code, the
result would be a lean FOP with incredible power ...
that
were part of the code used to start the Knuth branch, but I want to be
sure I'm allowed to do it.
.. and you wouldn't have to ask. :-)
OTOH, I'm not entirely sure how to design and implement such a system
that dynamicly loads code into the layout system.
The set of extensions (a couple of new properties, and some new value
for an existing one)
New properties are fine, new values to existing properties are bad, I
think. It basicly makes the fo file into a FOP file, since no other
processer can handle the 'illegal' values. It would be better to define
fox:display-align="fill" which when specified will override the value of
display-align.
is aimed to give the user more control about the
page breaking: in particular, via these extensions it is possible to
give the application a list of properties that can be adjusted in order
to fill all the available bpd of a region (in addition / substitution to
the spaces between blocks [1]).
I wonder why you don't mention that line-height is a min/opt/max space.
Surely that will (when implemented) be usefull way to limit the size og
empty areas.
