Is there an easy way around this? IE a php class/function that understands SVG w/ xlink and can replace the use tags with the polygons they refer to? If not, I'll have to try to write one, but I'd rather not ...

I just did, haven't tested yet, but this may work -

This does work (fixed version of function): function use2polygon($use,$polygon) { // get the xy coords $x = 0; $y = 0; if ($use->hasAttribute('x')) {

      $x = 0 + $use->getAttribute('x');
      }

if ($use->hasAttribute('y')) {

      $y = 0 + $use->getAttribute('y');
      }

// clone the polygon if ($polygon->hasAttribute('points')) { $points = preg_replace('/\s+/',' ',$polygon->getAttribute('points'));

      $pointArray = explode(' ',$points);
      $sizeof = sizeof($pointArray);
      for ($i=0;$i<$sizeof;$i++) {
         $foo = explode(',',$pointArray[$i]);
         $foo[0] = $x + $foo[0];
         $foo[1] = $y + $foo[1];
         $pointArray[$i] = $foo[0] . ',' . $foo[1];
         }
      $points = implode(' ',$pointArray);
      $newPolygon = $polygon->cloneNode(true);
      $newPolygon->setAttribute('points',$points);
      $use->parentNode->replaceChild($newPolygon,$use);
      }

}

doh - for xml sanity, add this before the replaceChild if ($newPolygon->hasAttribute('id')) {

         $newPolygon->removeAttribute('id');
         }

Now it works, and makes identical svg image that works with convert. http://www.shastaherps.org/map/map22.svg vs http://www.shastaherps.org/map/map22.svg?convert=true
