Assumes pVectorWindow points to a valid LVectorWindow object
This example pans the image 5 pixels horizontally

L_INT LVectorWindow__SetPanExample(HWND hWndParent, LVectorWindow *pVectorWindow) 
{ 
   UNREFERENCED_PARAMETER(hWndParent); 
 
   L_INT nRet; 
   POINT panPoint; 
 
   nRet = pVectorWindow->GetPan(&panPoint); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   panPoint.x += 5; 
 
   //Must disable auto-scroll to use SetPan 
   pVectorWindow->EnableAutoScroll(FALSE); 
 
   nRet = pVectorWindow->SetPan(&panPoint); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   return SUCCESS;
