      Frank,

      Pretty interesting. Someone posted another example here in the past six months, though I can't seem to locate it.

      Here is another one I and some students worked on a couple of years ago.

      cheers,
      David

      Subject: [svg-developers] Behold my SVG editor written in SVG!


      Hello everybody,
      I'm new to this group and I'd like to show you a little thing I'm
      working at:
      *My path data editor*
      <http://frankbruder.fr.ohost.de/FeSVG/pathDataEditorDemo.svg> written
      in ECMAScript
      I'm working with Opera 9.21 but I stick to the specifications and it
      mostly works in Firefox too. Just click at any path in the image to edit
      it.
      I'm posting this for two reasons:
      First, I think it's a cool way to show the possibilities of
      SVG + ECMAScript. Writing an SVG editor as an SVG document.
      Somehow like that example of writing a raytracer in the POVRay scene
      description language, if you know what I refer to. I just think it's
      neat stuff so I want it to be seen.
      Second--and that's the reason why I do actually use that script for
      creating SVG documents--note that my editor handles quadratic bezier
      curves and elliptic arcs natively! You can see some of it in the comic
      caracter's hair. I haven't seen this feature in any fully developed
      vector drawing program yet.
      When you edit the bubble you'll see that the control elements for
      elliptic arcs will easily become confusing. There are more things which
      need improvement. But it works and I've been using it successfully.
      Now I'd like to know: What do you people think of it? Do you instantly
      get a hundred ideas for what such thing could be used for or is it just
      a senseless gimmick?
      If you've got questions, ask. I did not write any documentation so far.
      If you dare to test it with an other browser than Opera or Firefox,
      please tell me if it works or if your browser crashed. (I'm not really
      just kidding. I've had some stability issues during development. Though
      I'm not sure if that had been related to my code. It might just have
      been an Opera + Win98 related problem.)
      And what about using parabolics and elliptics in vector drawing
      applications? Do you know, if there already is some development going on
      about it which I don't know about? And would you even use these path
      segment types if you could?
      I'm hoping for many replies, bye

      Frank
