Well if you set the JSVGCanvas to ALWAYS_DYNAMIC you can dynamically append (and remove) content from the document and the display will be updated accordingly (you must make sure that all modifications are made in the Canvas's UpdateManager's Runnable Queue - read the FAQ). To do this you would have to know how to read XML documents in pieces and then import those pieces into the displayed document. Alternately you could potentially build your graph on the fly (using methods like createElementNS) from the underlying data and append the dynamically generated SVG to the document. > And I have noticed in the SVG1.2 Specification a concept called > Progressive Rendering. http://www.w3.org/TR/2004/WD- > SVG12-20041027/progressiverendering.html > How far it can be used to load SVG documents. Which Batik versions > implemented that concepts. Batik does not implement progressive rendering. We only render when the document is fully loaded. But by loading a small initial document and the appending the rest of the data later you can simulate this. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
