Hi Fabian,
It is usually a case of getting the correct attributes. Batik tends to
follow the standard a bit more closely that some other implementations. The
following code works for me...posted sans the JFrame init...assumes a class
member JSVGCanvas named svgCanvas.
private void runDemo() {
svgCanvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
svgCanvas.addGVTTreeBuilderListener(new GVTTreeBuilderAdapter() {
@Override
public void gvtBuildCompleted(GVTTreeBuilderEvent e) {
svgCanvas.getUpdateManager().getUpdateRunnableQueue().invokeLater(new
Runnable() {
public void run() {
Element rect =
svgCanvas.getSVGDocument().createElementNS(SVGDOMImplementation.SVG_NAMESPACE_URI,
SVGConstants.SVG_RECT_TAG);
rect.setAttributeNS(null,
SVGConstants.SVG_X_ATTRIBUTE, "100");
rect.setAttributeNS(null,
SVGConstants.SVG_Y_ATTRIBUTE, "100");
rect.setAttributeNS(null,
SVGConstants.SVG_WIDTH_ATTRIBUTE, "100");
rect.setAttributeNS(null,
SVGConstants.SVG_HEIGHT_ATTRIBUTE, "100");
rect.setAttributeNS(null,
SVGConstants.SVG_FILL_ATTRIBUTE, "#2222ee");
Element animate =
svgCanvas.getSVGDocument().createElementNS(SVGDOMImplementation.SVG_NAMESPACE_URI,
SVGConstants.SVG_ANIMATE_TAG);
animate.setAttributeNS(null,
SVGConstants.SVG_ATTRIBUTE_NAME_ATTRIBUTE,
SVGConstants.SVG_OPACITY_ATTRIBUTE);
animate.setAttributeNS(null,
SVGConstants.SVG_VALUES_ATTRIBUTE, "1;0");
animate.setAttributeNS(null,
SVGConstants.SVG_DUR_ATTRIBUTE, "3s");
animate.setAttributeNS(null,
SVGConstants.SVG_REPEAT_COUNT_ATTRIBUTE, "indefinite");
rect.appendChild(animate);
svgCanvas.getSVGDocument().getDocumentElement().appendChild(rect);
}
});
}
});
Document doc =
SVGDOMImplementation.getDOMImplementation().createDocument(SVGDOMImplementation.SVG_NAMESPACE_URI,
"svg", null);
svgCanvas.setSVGDocument((SVGDocument) doc);
}
