   options.uFlags = L_LOADSVGOPTIONS_NONE; 
   options.SvgHandle = NULL; 
 
   /* Load the document as SVG */

   L_BOOL canLoad = FALSE; 
   nRet = L_CanLoadSvg(filename, &canLoad, NULL); 
   if (canLoad) 
   { 
      nRet = L_LoadSvg(filename, &options, NULL); 
      if (nRet != SUCCESS) 
         return nRet; 
 
      nRet = L_SvgAddElementIDs(options.SvgHandle);
