Methods, algorithms, software, apparatuses and systems for processing image data for imaging devices having irregular scan paths (e.g., scan paths that deviate from a conventional horizontal and/or straight line). The irregular scan paths generally correspond to actual locations of a line of output from an image output device (e.g., a printer). The method generally includes steps of selecting one or more of the input pixels, correlating a location of the selected pixel with a location on an irregular scan path, and producing an adjusted pixel based on a value of the selected pixel, the location on the irregular scan path, and/or values of one or more pixels near the selected pixel.
