Abstract
This is a method and apparatus for use in the 'color-graphics board' of a computer having a pictorial output visualizable in color. It is particularly suitable for use with computers of the Macintosh type of configuration, but is by no means limited to computers of that type. The invention affords to the operator of the computer the ability to select various bit levels for the pixels which together comprise the display of the computer. The bit levels may be selected at will depending upon the necessary degree of resolution and color selectability that characterize the diverse possible uses of the visual display of the computer.
