Nice.
Just, what do you mean with "default topics" - like just exporting the
TopicTypes coming with the DM Standard Distribution?

Since I remember my user-friend at the last developer meeting wanting a
Topicmap to Bitmap-Export, there might be an easy way we could integrate
this (maybe as an export option?) into this plugin, too, or?

The client-side source code for exporting to bitmap, as long as the
default canvas-based topicmap-renderer is used, should be easy as:

function convertCanvasToImage(canvas) {
  var image = new Image();
  image.src = canvas.toDataURL("image/png");
  return image;
}

While I guess that its quite straight-forwad to create a .PNG-File out
of a data-uri. At least I found a useful-looking comment in the php.net
community manual under
http://php.net/manual/en/function.base64-decode.php (currently the
second from top).

Tell me if we want to join these two export-options in your plugin.

Me personally, I am really looking forward trying out your SVG-Export
option and would be happy to test-drive file-compatibility with e.g.
Inkscape and give you feedback for consideration.

Nice greetings!
