Release soon?
Any plans for another release of Batik anytime soon?
Thanks,
-Archie

this is very good news. Looking forward to using SMIL in Batik.
Thanks for the info,

I think it’s been a long requested feature. :)

There are some things that are undefined about changes to animation
attributes, particularly with the timing attributes, I think. SMIL
Animation says this:
5.3. Constraints on manipulating animation elements
Language designers integrating SMIL Animation are encouraged to
disallow manipulation of attributes of the animation elements, after
the document has begun. This includes both the attributes specifying
targets and values, as well as the timing attributes. In particular,
the id attribute (of type ID) on all animation elements must not be
mutable (i.e. should be read-only). Requiring animation runtimes to
track changes to id values introduces considerable complexity, for
what is at best a questionable feature.
It is recommended that language specifications disallow manipulation
of animation element attributes through DOM interfaces after the
document has begun. It is also recommended that language
specifications disallow the use of animation elements to target other
animation elements.
Note in particular that if the attributeName attribute can be changed
(either by animation or script), problems may arise if the target
attribute has a namespace qualified name. Current DOM specifications
do not include a mechanism to handle this binding.
Dynamically changing the attribute values of animation elements
introduces semantic complications to the model that are not yet
sufficiently resolved. This constraint may be lifted in a future
version of SMIL Animation.
But, SVG 1.1 doesn’t specifically disallow changes to the attributes. I
will try to get to this soon then.

Hi Cameron,
good to hear! I will test the implementation and provide feedback.

ok, this restriction already existed for scripting paint server element
attributes.

hm, this is sad. Both ASV and Opera support changing SMIL attributes
from script and I also use this feature frequently. I can't find any
text in the animation chapter of the spec that would tell an author that
he can't modify SMIL attributes by script. It would be a restriction if
I can't do this in Batik.

sure.
Thanks again for your work and congratulations on getting this into the
trunk!

It's not specifically animation related... but please include the patch
in bug #40167 in the next release. It doesn't look like it's been
committed to SVN yet.
Thanks!

I have merged the anim branch back into the trunk now. This should give
a nearly complete SMIL animation implementation. There aren’t any
regressions for documents that have no animation, but there may still be
bugs with the animation stuff. Note that the animation engine isn’t
started unless there is at least one animation element in the document
at the time it is loaded, so if you only add animation elements from
script then it won’t work yet. All CSS properties are animatable, most
XML attributes are too. One notable omission is that animating paint
server element attributes is not supported yet.
Modifying attributes of animation elements while they are in the
document will not change the animation. Removing the element, changing
the attribute, then reinserting it will work. I believe this is
conformant, but I will have to dig deeper into the specs.
Please give it a try and file bug reports for any problems you find.

Yeah, once I’ve finished it and put the appropriate tests into regard,
I’ll merge it into the trunk. Really the anim branch has just been a
place for me to stick my animation code and have it versioned, as I
haven’t been doing any extensive testing of it or regression testing as
I’ve been going.

I would agree that if we have a finished (or even nearly finished)
SMIL animation engine then we should do a new release. In fact
should we just replace 'trunk' with the animation branch?
We might want to put a note on the download page indicating that
trunk is a bit unstable, but since at this point I can't imagine
releasing trunk without all the great the animation stuff I suspect
trunk has outlived it's usefulness (discussion should probably take
place on Batik-dev for this).
Other opinions?

Cameron,

Did I just read that right?
Is Batik about to provide support for SMIL Animation?
Will we have access to the whole kit-and-caboodle (everything in the SMIL animation module)?
Even:
<set begin="objectID.click" end="otherobjectID.end" ... />
and the like?
Will we, will we?
If you haven't guest already I'm quite keen on the idea.

Philip Fennell

There’ve certainly been enough changes to warrant a release, IMO. But as I am close to finishing animation support I’d like to get that in.
Maybe in a month or so. Thomas, Dieter?
