implementing background-image (bug 5180)

[Michael Gratton <mj...@recalldesign.com>]

Guys,

I need to be able to use the background-image property, which is not yet 
implemented <http://nagoya.apache.org/bugzilla/show_bug.cgi?id=5180>.

Is anyone working on this at the moment? If not, I'm happy to make an 
attempt at it. Is there anything I should know about implementing 
properties in FOP, or this one in general, that I wouldn't pick up from 
looking at the existing code?

Thanks,
Mike.

Hi, Michael

You picked a good one to get your feet wet with. No, I wouldn't say that
there is anything about this that is going to trip you up, or implementation
quirks that you wouldn't get from existing code (I assume we are talking
maintenance branch?).

One thing that you might end up doing, being unfamiliar with FOP source, is
to do way more for this property than you need. The background properties
are pure rendering traits, and with the exception of
background-position-horizontal and background-position-vertical, require
absolutely no more work at any stage of layout other than to ensure that
appropriate traits (instance variables)  are set on the affected areas that
are eventually passed to the renderers. Almost all of the real work is in
the renderer stage.

Regards,
Arved Sandstrom
