Re: Synchronizing JSVGCanvas

[André Ávila]

Hi Thomas,   I worked on this last night and got to a solution. Basically, I created a GlassPane on top of the canvases and added my own subclasses of the interactors to it. The GlassPane interactors just redirect the user input to all the canvases. It sounds simple, but in fact it required some work to get everything going.   The final result is not great, though, making the app look a little sluggish in less powerful boxes.   I'll give your idea a try, for it sure seems simpler than mine. I'm afraid the final result will be not different, though. Now I'm thinking on trying to use Overlays for that. I would keep the original document (JSVGCanvas) and draw the other documents as overlays on top of it.   My only concern is, again, keeping things in synch. Looking at SelectionOverlay, in TextSelectionManager, it looks like it all comes down to your approach: getRenderingTransform(), setRenderingTransform(). Would you think this is a good idea?   BTW, Thomas, I had some problems with SVN-06-03-27 (the one with your wonderful change to get rid of the DOM in the JGVTComponent). It looks like SVGs with embedded (base64-encoded) JPEG don't work anymore. I just downloaded SVN-06-03-30 to see if the problem persists, and then I'll open a new thread.   Best regards,   André <[EMAIL PROTECTED]> escreveu na mensagem news:<[EMAIL PROTECTED]>...
