----------------------------------
Summary: Changing an SVGAnimateElement at runtime doesn't work
Key: BATIK-1099
URL: https://issues.apache.org/jira/browse/BATIK-1099
Project: Batik
Issue Type: Bug
Components: GVT
Affects Versions: 1.7
Reporter: Marco Herrn
Modifying an existing SVGAnimateElement at runtime leads to no visible change.
See for example this SVG snippet:
<g id="someId">
<line ... />
<line ... />
<animate dur="0.2" from="0" to="1" repeatCount="indefinite"
attributeName="stroke-opacity"
calcMode="discrete"/>
<animate dur="0.2" from="0" to="1" repeatCount="indefinite"
attributeName="fill-opacity"
calcMode="discrete"/>
</g>
Trying to change this at runtime with the following code:
canvas.getUpdateManager().getUpdateRunnableQueue().invokeLater(new Runnable() {
public void run() {
for (SVGElement elm : currentlySelectedElements) {
elm.setAttributeNS(null, "stroke", "green");
Set<SVGAnimateElement> animateElements= getAnimateElements(elm);
for (SVGAnimateElement anim : animateElements) {
anim.setAttributeNS(null, "dur", "1");
}
}
}
});
should result in a slower blinking frequency. However the blinking frequency
stays the same. The stroke color is changed, however. So this seems to be a
problem only with SVGAnimateElements.

problem
