I'm trying to manually display and update the magnifier glass over an image displayed using LImageViewer. Can I do this using L_StartMagGlass and L_UpdateMagGlass?

Thanks,
Arg

Yes you could certainly use those functions with LBitmapWindow because you can use LBitmapWindow::GetBitmapWnd for the HWND of the window and LBitmapBase::GetHandle to get the BITMAPHANDLE of the bitmap.  You can then use that data to call L_StartMagGlass. 

Also you can create your own class and inherit LBitmapWindow to override LBitmapWindow::MagGlassCallback, but you must make sure to call LBitmapWindow::EnableCallBack(TRUE) first.

Sorry, but the question was about using magnifier API functions with LImageViewer not LBitmapWindow.

Similiar functions exist in the LImageViewer class...have you tried using LImageViewer::GetCellWindowHandle and LImageViewer::GetBitmapHandle and then passing that data to L_StartMagGlass?
