ABSTRACT:
A method and apparatus for filling an area of a computer display with a preselected color is provided. Typical computer systems software provides the capability to represent 256 different intensities of a color. However, many color displays cannot support the displaying of 256 intensity levels. The present invention provides a method and apparatus for mapping the higher number of intensity levels supported by the systems software to the lower number of intensity levels actually supported by the display. In a preferred embodiment, four picture elements (pels) of a display are logically grouped together to create a super-pel. By varying the intensity level in each pel of a super-pel, the effective number of intensity levels for a given color can be increased.
