Attributes that don't have a prefix (i.e. xlink:) should be in the null namespace. Attributes that have a prefix should be in the namespace associated with that prefix. In SVG this means that essentially only the xlink attributes need namespaces. > But when I do this > public void setVisible(final Element elt, boolean b) { > final Element mask = elt2mask.get(elt); > if (mask == null) > return; > Element anim = (Element) mask.getElementsByTagNameNS(null, "animate").item(0); > String animId = anim.getAttribute("id"); > if (b) { > SvgRepaintEngine.getInstance().push(new AttributeUpdateTask(mask.getAttribute( > "id"),"opacity", "1")); > SvgRepaintEngine.getInstance().push(new AttributeUpdateTask(animId, "from", > "0")); > SvgRepaintEngine.getInstance().push(new AttributeUpdateTask(animId, "to", "1" > )); > } else { > SvgRepaintEngine.getInstance().push(new AttributeUpdateTask(mask.getAttribute( > "id"),"opacity", "0")); > SvgRepaintEngine.getInstance().push(new AttributeUpdateTask(animId, "from", > "1")); > SvgRepaintEngine.getInstance().push(new AttributeUpdateTask(animId, "to", "0" > )); > } > > the animation does not perform, and the opacity changes immediately > (I tried to remove the first change) I think this is because you haven't started the animation, probably by calling 'beginElement()' in your case. > Note that the SvgRepaintEngine only calls the invokeLater of the > update manager to make a setAttribute You _really_ should have a way to bundle those changes together, you could get strange results if a repaint started in between some of those set attribute calls. > On Sat, Jan 9, 2010 at 2:58 PM, <[email protected]> wrote: > Hi Dao, > > dao <[email protected]> wrote on 01/06/2010 09:17:33 AM: > > > > hello, I am running into a problem while attempting to animate an object. > > > > I create an animation object using batik and I add this to my > > ALWAYS_DYNAMIC canvas.
