Method and apparatus for generating optically readable dot image data and recording medium

摘要

The present invention selects an appropriate composition pattern even if there is provided a plurality of composition patterns for dot image data based on the number of pixels associated with printing. Namely, in order to print a readable dot, an image data generation method is used for setting a composition pattern of this dot. This method determines the number of pixels associated with printout of the composition pattern in consideration of enlargement of the dot when printed. This method also uses a composition pattern which minimizes dispersion of pixels constituting the corresponding dot. By doing so, the method uniquely determines an optimal dot composition pattern for printing.
