SVG (Scalable Vector Graphics) is a modern technology, allowing to show vector images on web pages. A family tree in SVG format can be scaled in the widest range! To see the tree in this format, your browser should support SVG. If your browser is Mozilla Firefox or Opera they already have built-in SVG support. Internet Explorer requires special plug-in, for example, Adobe SVG Viewer which can be loaded free of charge from here (version 3.03) or here (version 6.0 alpha).

Since Adobe SVG Viewer works faster it is recommended to install it in yours Firefox or Opera, replacing their built-in SVG engines.

    In Mozilla you can do it as follows:
  1. Download and install Adobe SVG Viewer version 6.0 alpha (version 3.03 crashes Mozilla)
  2. Enter about:config in the browser's address line - the long list of preferences will appear in the window.
  3. Find the line svg.enabled with value true;
  4. Click RIGHT mouse button on it and choose "Toggle" in the dropdown menu - the value will turn to false;
  5. Close the browser.
  6. Locate C:\Program Files\Common Files\Adobe\SVG Viewer 6.0\Plugins directory.
  7. Copy 2 files NPSVG6.dll and from there to Mozilla's plagin directory - usually it is C:\Program Files\Mozilla Firefox\plugins
  8. Launch the browser - now it will use Adobe SVG Viewer.

Installing Adobe SVG Viewer in Opera is similar.
