    read the setting;

    determine a first set of coordinates of the pixel based on the setting and for each cell of a sparse conversion map;

    interpolating the first set of coordinates to obtain a second set of coordinates, wherein the second set of coordinates is associated with a second image,wherein the first image would be less rectilinear than the second image when the first image and the second image are displayed,wherein the second image is associated with the sparse conversion map corresponding to a sparse grid of pixels, andwherein the second image is associated with a full conversion map corresponding to a full grid of pixels with a plurality of cells; and
