Modifying the attributes of an animation element while it is in the document will not change the animation. This is half bug, half underdefined-ness in the SVG specification. What will work, though, is removing the animation element from the document to stop it, and re-inserting it when you want to start it again. Alternatively, you could use the beginElement() and endElement() methods on animateColorE (you’ll need to cast it to ElementTimeControl to get those methods). That will start or stop the animation. (Technically, it’s like adding an entry to the begin="" or end="" attribute with the current time.) -- Cameron McCormack ≝ http://mcc.id.au/ --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
