For each slide all animations are exported into the svg document:
the exported animation elements are the same that are created by
the odp format exporter.
Interesting - but maybe easier to have some pre-processed subset
first?
Well surely I chose the hard way, but indeed after seeing how
animations are exported in odp, it looks to me the more natural
one.
Not sure what you mean with "to have some pre-processed subset"
could you elaborate ?
== 3 ==
Read SMIL documentation section on transition filters.
In order to understand how to implement the javascript code for
performing the exported animations, I started analyzing the slideshow
animation engine.
Hmm - I guess re-implementing larger parts of the animation engine
in JS is out of scope for this project (though of course would be
cool to have) - maybe limiting ourselves to what smil is natively
supported in a browser (e.g.
https://developer.mozilla.org/en/svg/svg_animation_with_smil) is
better?
What I am aiming to do is to perform a selective port of the
slideshow engine to JavaScript. I'm still analyzing the animation
engine implementation though, and I have to admit that is not a
smooth path.
Obviously the benefits would worth the effort, making a strong
base for being able to implement the shape effects more easily.
For instance I have already a good idea of how to port animation
node classes, but then there is the need for events and activities
too.
As for exploiting the smil-subset supported by the svg language,
I took it into account, anyhow after performing some test I saw
that support for it is lacking in Firefox 3.6.x and above all in
Internet Explorer 9, and also Google Chrome have same issue.
I attached a patch set based on the master branch, as it was on
Monday July 7, that includes all enhancements I implemented until now.
Thx a lot, will look into this - please give me a day or two, just
back from vacation. ;)
No problem! :)
Cheers,
Marco
