Abstract
This invention discloses a method and apparatus for generating dots in image reproduction, and relates to the field of image reproduction in the printing industry. The method comprises performing a binarization process on a threshold matrix of one or more basic dots according to level thresholds to obtain a set of level-binarization matrixes corresponding to the threshold matrix; determining substitution binarization matrixes and auxiliary binarization matrixes from the set of level-binarization matrixes; performing a Boolean operation on the substitution binarization matrixes and the auxiliary binarization matrixes to generate resulted binarization matrixes; substituting binarization matrixes to be substituted in the set of level-binarization matrixes with the resulted binarization matrixes; and according to the substituted set of level-binarization matrixes, forming a substituted threshold matrix, and generating shape-varied dots according to the substituted threshold matrix. The shapes of dots with some grayscale in basic dots are changed by Boolean calculation among binarization matrices, thereby achieving the purposes of changing the overall shape of the basic dots and constructing dots with complicated shapes using dots with simple shapes, so that it is simple and easy to implement.
