Abstract: A method for scaling an input bitmap by a non-integer factor with improved image quality comprises the steps of: selecting a pel in the input bitmap; selecting a neighborhood surrounding the selected pel; searching a set of image feature patterns to find an image feature pattern that matches the selected neighborhood; and writing a blocks of bits to an intermediate bitmap based on the match. The appropriate block of bits is obtained by subsampling an image enhancing tile which corresponds to the matched image feature pattern. The process of matching neighborhoods and writing a subsampled image enhancing tile (i.e., block of bits) to the intermediate bitmap is repeated for each pel in the input bitmap. When the image enhancing tiles are subsampled to the proper size and shape and placed in the proper locations in the intermediate bitmap, the jagged “stair-step” look of curved and diagonal image features in the input image is smoothed, resulting in improved quality.
