Re: SVG update performances over X11 export display
Hi Olivier, I have very bad performances using batik to display and update a SVG over a X11 export display. I don't know about the internals of X11 export display, but I can imagine that would be close to Remote Desktop and/or VNC, possibly more efficient. But given that Java ultimately deals with buffered images(bitmaps) I guess the X11 export's potential efficiency, regarding vector operations, is kinda chopped down (please correct me if I'm wrong!)... It might be possible to implement Batik rendering directly using X11 primitive operations, which would then take advantage of the X11 export display, but that would probably be a crazy project (in terms of the amount of work and required Batik refactoring)! :-D Is there any documentation to understand the policy of batik to do the repaint? You may take a look at the Batik architecture [1], but that's only a starting point. The repaint internals are likely within the GVT module, but I'm not sure if, else than the Javadoc (and the source code itself, naturally), more documentation is available... When I do a setAttribute style, for example, does batik repaints only the necessary part of the display (the rectangle surrounding the element)? That should be the case. If I have several layers, does batik repaints each one? I guess not. As far as I know, the repaint is made by areas so, if you update the several layers in a single operation -- or using a batch operation with the already stated (un)suspendRedraw -- than a single repaint would be expected. Thomas is the GVT expert [2] so he may be able to shed some light here; as for me, this is hitting the limit of my current Batik internals knowledge, so I really doubt I can provide much more useful information. As a side note, why not place some debug output in the repaint classes and check what Batik is doing for yourself...? ;-) Hope this helps, Helder [1] http://xmlgraphics.apache.org/batik/using/architecture.html [2] http://xmlgraphics.apache.org/batik/contributors.html#expertise - To unsubscribe, e-mail: batik-users-unsubscr...@xmlgraphics.apache.org For additional commands, e-mail: batik-users-h...@xmlgraphics.apache.org
Re: Dynamic addition of scripts to SVG in Batik
Hi Tanul, Tanul smart.p...@gmail.com wrote on 11/24/2009 01:55:07 PM: I am trying to update the ecma script in the SVG document at runtime. i.e. the content of the script/script tag is updated during the course of execution of the application. Even after updating/adding the script tag, the updated script is not available for execution. I'm not sure we support 'updating' but if you add a new script element Batik should execute the code it contains. Is it possible to update the scripts dynamically using batik? I have done it in the past. If you can produce a stand alone example of the problem it might help figure out what the problem is.

RE: SVG update performances over X11 export display
Do you mean that if I set org.apache.batik.min_repaint_time=100ms (10 points a sec, this is my requirement) and I call the invokeLater with higher frequency(say 50ms), batik will pile up the runnables in the queue and poll them 10 times a second? To better understand, in my example, the costfull redraw will be trigged each 100ms and will process 2 runnables each trig?

RE: SVG update performances over X11 export display
Well, first feedback disabling the double buffering : ugly! javax.swing.RepaintManager.currentManager(null).setDoubleBufferingEnabled(false); In display local or export mode, The canvas flikrs and beautiful white rects quickly appears. It actually demonstrates that batik updates only the necessary parts, as the white rects are over the regions to repaint. I am wondering if JAVA is a good solution since I will export the display. Do you know an other way to export the display of several linux stations on the same monitor? I have several hosts that will compute the canvas, and my user needs to have the different canvas on the same screen (side by side or on top of each other) De : thomas.dewe...@kodak.com [mailto:thomas.dewe...@kodak.com] Envoyé : mardi 1 décembre 2009 12:27 À : batik-users@xmlgraphics.apache.org Cc : batik-users@xmlgraphics.apache.org Objet : RE: SVG update performances over X11 export display Hi Olivier, HODAC, Olivier olivier.ho...@airbus.com wrote on 12/01/2009 05:18:19 AM: I have very bad performances using batik to display and update a SVG over a X11 export display.

You can use JSVGCanvas.setDoubleBufferedRendering(false) - note that this is quite different from turning off Swing's double buffering (as you were doing in a different message).

When a runnable is completed it checks if there is another runnable ready to run. If there isn't a runnable to run it updates the canvas.

This behavior is controlled by the MIN_REPAINT_TIME in the UpdateManager which you can set with the property: org.apache.batik.min_repaint_time That said if you can 'logically' group the updates into sets then suspending redraw and re-enabling it is probably better. -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.

JavaDoc
Hi I'm searching the org.w3c.dom.svg JavaDoc because a lot of Batik features are based on this. Is this part of the Batik project? Where can I find it?

Re: JavaDoc
I'm not sure where the javadoc is, but the spec will get you far here: http://www.w3.org/TR/SVG/types.html#BasicDOMInterfaces good luck!
