Abstract
A fast, highly efficient method for storing computer display information (13) which contains both text and graphics (26, 27). The method separates text (26) from graphics (27) compressing, storing each separately to optimize compression. The method allows use of multiple text fonts (21) on the same display (13) and is simple enough for an 8-bit microcomputer.
