Other software may use alpha blended transparent elements in the GUI independently of OS provided APIs by precomposing elements in an off-screen memory buffer before displaying them. (Such as when displaying partially transparent composited elements in an embedded system which provides only a simple frame buffer.) Compositing software is used to combine images, and makes extensive use of alpha compositing techniques.
