Claim Text:
1. A method for enhancing a raster image that comprises pixels, a pixel having a position in the raster image and a grayscale value, the method comprising the steps of: a) defining a second raster image of equal dimensions to said raster image; b) selecting a target pixel in the second raster image, having a target position; c) deriving a grayscale value for the target pixel from a grayscale value of a pixel in said raster image that is in a range of a pixel on a position corresponding to the target position, in order to disperse the grayscale value of a pixel in a predetermined range around its original position and to enhance the second raster image for further processing in a halftoning process without using pixel segmentation.
