Ok, found the last piece, updating the time is a little bit strange.
Using this code to update the animation engine, the animation works
finally :-)
if(!mAnimationEngine.hasStarted()) {
mAnimationEngine.start(System.currentTimeMillis());
mStartTime = System.currentTimeMillis();
} else {
mAnimationEngine.setCurrentTime((System.currentTimeMillis()
- mStartTime) / 1000f);
}
Got that code snippet from TimedDocumentRoot.convertWallclockTime which
is not accessible from outside.
Best regards,
Oliver

Hi,
I'm a step further using the SVGAnimationEngine, but the resulting
Image is empty because nothing is drawn :-(.
With Squiggle the SVG animation is correctly displayed.
This is the code I'm using:
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
SVGDocument doc =
f.createSVGDocument(findFile(pFilename).toString());
UserAgentAdapter userAgent = new UserAgentAdapter();
BridgeContext ctx = new BridgeContext(userAgent);
//parse document
GVTBuilder builder = new GVTBuilder();
GraphicsNode gvtRoot = null ;
try {
ctx.setDynamicState(BridgeContext.DYNAMIC);
gvtRoot = builder.build(ctx, doc);
}
catch (BridgeException e) {
new IOException("Error loading svg image", e);
}
//create animation engine
ctx.setAnimationLimitingNone();
SVGAnimationEngine animationEngine = ctx.getAnimationEngine();
//draw image
if(!mAnimationEngine.hasStarted()) {
mAnimationEngine.start(System.currentTimeMillis());
} else {
mAnimationEngine.setCurrentTime(System.currentTimeMillis());
}
gvtRoot.paint(pGraphics);

Oliver

Hi,
for a small java game I would like to pre-render SVG Animations into
BufferedImages.
Rendering should run in the same thread, without using classes which
starts an own thread like the UpdateManager.
How can I apply the animation manually on the tree?
This is the code I'm using at the moment:
//load image
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
Document doc =
f.createDocument(findFile(pFilename).toString());
UserAgentAdapter userAgent = new UserAgentAdapter();
BridgeContext ctx = new BridgeContext(userAgent);
GVTBuilder builder = new GVTBuilder();
GraphicsNode gvtRoot = null ;
try {
ctx.setDynamicState(BridgeContext.DYNAMIC);
gvtRoot = builder.build(ctx, doc);
}
catch (BridgeException e) {
new IOException("Error loading svg image", e);
}
//draw static image
Graphics2D graphics = (Graphics2D) pGraphics.create();
graphics.transform(mTransformation);
gvtRoot.paint(graphics);
Thanks in advance,
Oliver
