| 1. A computer-readable medium having stored thereon computer-executable instructions for a method of converting an incoming
pixel data of a first format comprising a plurality of pixel elements in four colors for rendering on a display of a second
format comprising a plurality of subpixels in four colors, said method comprising:
determining an implied sample area for each data point of said incoming pixel elements;
determining a resample area for each subpixel in said display;
forming a set of coefficients for each said resample area, said coefficients comprising fractions whose denominators are a
function of the resample area and whose numerators are a function of an area of each said implied sample area that may partially
overlap said resample areas;
multiplying the incoming pixel data for each implied sample area by the coefficient resulting in a product; and
adding each said product to obtain luminance values for each resample area.
