Comments

To attach a Zoom View to a window, call the LBitmapWindow::AddZoomView function.

When a Zoom View is no longer needed, call the LBitmapWindow::DestroyZoomView function to stop the specified Zoom View procedure and to detach it from the window handle.

If you need to destroy all the zoomed views that are attached to a specified window, destroy them from the last Zoom View to the first Zoom View. For example, if you have 5 Zoom Views associated with the specified window you need to do the following:

L_UINT uCount,i; 
if(m_LAniWnd.HasZoomView ()) 
{ 
   uCount = m_LAniWnd.GetZoomViewsCount (); 
   for(i=0; i < uCount;++i) 
   { 
      m_LAniWnd.DestroyZoomView(uCount-i-1); 
   } 
}
