Hi,
I would like to know how to handle animations with batik, especially the
animate tag.
If I put the following svg code into an svg graphic and open it with a java
application with batik all works just fine and it'll be animated:
<rect x="100" y="100" width="500" height="500">
<animate attributeType="CSS" attributeName="opacity"
calcMode="discrete"
from="1" to="0" dur="1s" repeatCount="indefinite" />
</rect>
But what do I have to do, if I want to do exactly this during runtime?
I've tried this:
SVGOMAnimationElement animate = (SVGOMAnimationElement)
this.svgDocument.createElementNS(SVGDOMImplementation.SVG_NAMESPACE_URI,
SVG12Constants.SVG_ANIMATE_TAG);
animate.setAttribute("dur", "1s");
animate.setAttribute("values", "0; 0; 1; 1");
animate.setAttribute("keyTimes", "0; 0.5; 0.7; 1.0");
animate.setAttribute("attributeName", "opacity");
animate.setAttribute("attributeType", "CSS");
animate.setAttribute("repeatCount", "indefinite");
rect.appendChild(animate);
animate.beginElement();
but this didn't get animated, so I've tried to use the SVGAnimationEngine, but
I'm not sure how to use the addAnimation() method, or even if I need to do
that:
SVGAnimationEngine aEngine = getSVGAnimationEngine();
aEngine.addAnimation((AnimationTarget) rect,
SVGAnimationEngine.ANIM_TYPE_CSS, "?", "?", AbstractAnimation???);
How can I setup an AbstractAnimation?
Any help is very appreciated
Thanks in advance.
Kind regards,
Fabian
