Claim One:
1. A method for improving the quality of a pixel pattern containing a line segment having a tick or notch, said method comprising the steps of: receiving a block of pixels from an original pixel pattern, said block of pixels having rows and columns of pixels, said block of pixels containing one or more target pixels, forming a first portion of a pixel pattern, and neighboring pixels of said target pixels, each of said target pixels having four faces, each of said faces opposing an adjacent pixel; detecting whether a first target pixel meets a first condition, said first condition being that said first target pixel is a pixel of a first type having three of its faces opposing a pixel of a second type and one of its faces opposing another pixel of said first type, said another pixel of said first type being in one of said rows or columns containing all pixels of said first type; replacing said target pixels, if said first target pixel is detected to meet said first condition, with one or more lines of replacement pixels of said first type, said one or more lines of replacement pixels of said first type being parallel and adjacent to said one of said rows or columns containing said all pixels of said first type, and with one or more lines of replacement pixels of said second type parallel to said one or more lines of said replacement pixels of said first type; and outputting said lines of replacement pixels of said first type and said second type for printing.
