[Cjk] what's the meaning of Simplify(0, 2)?

[Liu DongMiao]

hello, everyone, do you know the meaning of Simplify(0, 2) in Mr. Werner's
scripts?
thanks.

i dont understand, from the documents of fontforge, i got this information:
http://fontforge.sourceforge.net/elementmenu.html#Simplify
Simplify(flags,error[,tan_bounds[,bump_size[,error_denom,line_len_max]]]) With
no arguments it does the obvious. If flags is -1 it does a
Cleanup<http://fontforge.sourceforge.net/elementmenu.html#Cleanup>,
otherwise flags should be a bitwise or of

   - 1 -- Slopes may change at the end points.
   - 2 -- Points which are extremum may be removed
   - 4 -- Corner points may be smoothed into curves
   - 8 -- Smoothed points should be snapped to a horizontal or vertical
   tangent if they are close
   - 16 -- Remove bumps from lines
   - 32 -- make lines which are close to horizontal/vertical be
   horizontal/vertical
   - 64 -- merge lines which are nearly parallel into one
   - 128 -- change which point is the start point if a contour's start
   point is not an extremum

 The error argument is the number of font units by which the modified path
is allowed to stray from the true path.
The tan_bounds argument specifies the tangent of the angle between the
curves at which smoothing will stop (argument is multiplied by .01 before
use).
And bump_size gives the maximum distance a bump can move from the line and
still be smoothed out.
If a fifth argument is given then it will be treated as the denominator of
the error term (so users can express fraction pixel distances).
Generally it is a bad idea to merge a line segment with any other than a
colinear line segment. The longer the line segment, the more likely that
such a merge will produce unpleasing results. The sixth argument, if
present, specifies the maximum length for lines which may be merged
(anything longer will not be merged).
