Example

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;
