uIndex	Index of the zoomed view to be destroyed. This is a zero-based index.

Returns

SUCCESS	The function was successful.

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);
      }
   }
