Greetings, I'd like to inquire about the current state of Batik with respect to dynamically updating documents via the DOM. I've seen a few messages in the list archives suggesting that some dynamic features work in the 1.5 beta, however my updates don't seem to work. (I also tried the latest version from CVS, no luck.) What I'm doing is extending JSVGComponent with a class that loads a document, and then modifies the DOM programmatically via Java (no scripting.) My changes never seem to get displayed in the JSVGComponent. The updates I'm doing are pretty simple- I'm adding <svg> elements that contain <line> elements. If I write out the updated SVG document to a file, I can successfully view my added items with the batik-svgbrowser.
I also tried forcing a re-display by calling setSVGDocument(getSVGocument()); but I get a NullPointerException. Should I just cool my heels and wait for 1.5 final, or is there a way to force newly added DOM elements to be displayed? Will dynamic updates eventually be fast enough for implementing interactive drawing? Some background on what I'm doing, in case anyone finds this interesting- I'm extending JSVGComponent to implement a whiteboard-like drawing tool. The basic idea is to implement "scribbling" over a displayed SVG document. The scribbles are recorded with time indices, which I later use to generate an animated SVG doc. The generated SVG references the original SVG doc to use as its background. An example is worth a thousand words, so I'll point you to http://erudycja.rutgers.edu/~armhold/svg/scribble.html. You'll need an SVG browser that supports animation. Thanks for any help. -- George Armhold Rutgers University eLearning Grant, DCIS --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
