Abstract
A method for sharpening the corners of digital image data to overcome corner rounding when displayed or printed. The method comprises stepping a window across the image data and comparing that windowed data to a template. Upon determining a match, pixel data is either substituted into the image bitmap data at that location, or a signal is generated which will appropriately modify the writing of that image data. The data substitution or generated signal will achieve a localized clustering or “ear” of toner/ink, or in the alternative for inside corners the localized clustered absence of toner/ink. The result of this clustering is a sharpening of the corners so that they image as intended by the bitmap.
