This example gets and updates the property of the object
passed by the caller

L_INT LAnnAutomation_GetPolyFillModeExample(LAnnAutomation  * pAnnObject) 
 
{ 
   L_INT nRet; 
 
   L_UINT PolyFillMode; /* Object's polygonal fill mode  
 */ 
 
   /* Change the fill mode */ 
 
   PolyFillMode = pAnnObject->GetPolyFillMode(); 
 
   if (PolyFillMode == ANNPOLYFILL_WINDING) 
   { 
      nRet = pAnnObject->SetPolyFillMode(ANNPOLYFILL_ALTERNATE,  0); 
      if(nRet != SUCCESS) 
         return nRet; 
   } 
 
   else 
   { 
      nRet = pAnnObject->SetPolyFillMode(ANNPOLYFILL_WINDING, 0); 
      if(nRet != SUCCESS) 
         return nRet; 
   } 
 
   return SUCCESS;
