Example

L_INT LAnnPolygon_GetPolyFillModeExample(LAnnPolygon  * 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;
