<p>A method to use most of the colors that are available when rendering color images where a limited number of colors are available such as rendering images in VGA mode. The instant invention determines the maximum value of the color intensity values of a true color to display at a given (x, y) position. The number of full intensity values and half intensity values are determined and the number of half intensity color values are maximized. A halftone matrix is used and a halftone value is chosen from the halftone matrix using a modulo function. The color to be used at the (x, y) position is then selected based upon the full intensity values and the halftone value.</p> |
