Hello,
Are you talking about this? ((SVGOMAnimationElement)anim).beginElement(); In this case, what's the best practice? It has to be called within a runnable of the runnableQueue of the canvas? Is that the right cast?

If you don't set all the attributes in the same runnable then Batik is free to trigger a rendering between them. This is very likely to cause odd behavior. Additionally, there is non-trivial overhead associated with running a runnable, so having a runnable set just one attribute will add significant overhead. I'd suggest simply adding a 'submit' method to your SvgRepainEngine that submits one Runnable with the list of 'Task' objects you have pushed since the last call to 'submit'. > On Tue, Jan 12, 2010 at 11:56 AM, <[email protected]> wrote: > Hi Dao, > > dao <[email protected]> wrote on 01/11/2010 06:22:58 PM: > > > Actually, I created the anim elements with the namespace > > "http://www.w3.org/2000/svg <http://www.w3.org/2000/svg> ". > > It is in fact null... how can I know which element belongs to > which namespace? > Attributes that don't have a prefix (i.e. xlink:) should > be in the null namespace.
