Abstract:
In a system that has multiple level pixel data that corresponds to a color image, a method for reproducing the color image on a medium, the method comprising steps for:analyzing the multiple level pixel data to determine a dot placement schema and to determine valid pixel levels and to determine valid pixel sizes; storing, in a data structure having one or more rows, dot placements for the dot placement schema within each row of the data structure, wherein each row corresponds to one or more of the valid pixel levels and wherein the data structure accommodates the valid pixel sizes, wherein each dot placement is representative of one or more of the valid pixel levels; accessing specific rows of the data structure to obtain the dot placements for multiple pixels, wherein levels of the multiple pixels identify the specific rows that contain the dot placements for the one or more pixels of the image; and for each of the multiple pixels, placing dots on the medium according to the dot placements in the data structure.
