Hello, I have very bad performances using batik to display and update a SVG over a X11 export display. Is there any documentation to understand the policy of batik to do the repaint?
When I do a setAttribute style, for example, does batik repaints only the necessary part of the display (the rectangle surrounding the element)? If I have several layers, does batik repaints each one? Etc... -----Message d'origine----- De : HODAC, Olivier Envoyé : lundi 30 novembre 2009 16:24 À : batik-users@xmlgraphics.apache.org Objet : RE: SVG update performances over X11 export display Great! I am watching the sources of Batik, but I cannot get the behaviour: When I suspendRedraw, my invokeLater calls piles up the runnables in the runnableQueue. But when I release (unsuspend), what happends? I suppose the update manager unpiles the runnables. Does the repaint made only once when the queue is empty? It is not clear... -----Message d'origine----- De : Helder Magalhães [mailto:helder.magalh...@gmail.com] Envoyé : lundi 30 novembre 2009 14:53 À : batik-users@xmlgraphics.apache.org Objet : Re: SVG update performances over X11 export display Hi Olivier, > Is there a way to do this with the batik framework: > > beginBatchModifications() > thread1 -> getUpdateRunnableQueue().invokeLater(runnable1) > thread2 -> getUpdateRunnableQueue().invokeLater(runnable2) > thread3 -> getUpdateRunnableQueue().invokeLater(runnable3) > thread2 -> getUpdateRunnableQueue().invokeLater(runnable4) > thread1 -> getUpdateRunnableQueue().invokeLater(runnable5) > endBatch() > > > so that I will not have to manage my synchronized queue of runnable and > ensure the repaint is performed by the endBatch? Well, SVG has the "(un)suspendRedraw" [1] methods, which Batik implements [2]. ;-) Hope this helps, Helder [1] http://www.w3.org/TR/SVG/struct.html#DOMInterfaces [2] http://xmlgraphics.apache.org/batik/javadoc/org/apache/batik/dom/svg/SVGSVGContext.html --------------------------------------------------------------------- To unsubscribe, e-mail: batik-users-unsubscr...@xmlgraphics.apache.org For additional commands, e-mail: batik-users-h...@xmlgraphics.apache.org This mail has originated outside your organization, either from an external partner or the Global Internet.
