points that may be removed from a glyph definition while causing minimal or no distortions to the shape of the given glyph for segment removal a maxim length and or angle for a redundant segment is defined the specified value for the maxim length and or angle may be user defined or determined automatically based on simplification criteria typically a larger maxim length and or angle results in additional simplification but may also result in additional visible distortion the maxim length is typically determined by the desired quality of the result stroke font desired a straight segment whose length and or angle is less than or equal to the specified values is simplified or removed by removing one or more of the points from the outline of the glyph the removal process may be implemented by an iteration through the points of all the contours and determining the length of each segment defined by a pair of n i n i 1 vertices and removing the segments that satisfy the condition length and or angle conditions each contour is processed repetitively until the number of removed segments is zero this iteration process is repeated for each of the contours of the outlines of the glyph during the bezier arc degree reduction process 2104 bezier arcs are simplified bezier arcs are defined by polynomials of 2nd quadratic bezier or 3rd cubic bezier degree.
