### ----------------------
112
### Sharpen mode:
113
###    =1 : Unsharp masking (from warpsharp)
114
###    =2 : Unsharp masking (from variableblur) 
115
###    =3 : Range sharpening
116
###    =4 : Nonlinear sharpening (original  version)

### preblur [string: "ON","OFF",...]
138
### --------------------------------
139
### Mode to avoid noise sharpening & ringing (only used in Smode=3,4,5)
140
### "ON" is sufficient to prevent ringing, but to prevent noise sharpening you should set your own denoiser
141
###    Usage:   LSFmod(preblur="YourFavoriteDenoiser()")
142
###    Example: LSFmod(preblur="FFT3Dfilter(sigma=4,plane=0)")
143
###
144
###
145
### secure [bool]
146
### -------------
147
### Mode to avoid banding & oil painting (or face wax) effect of sharpening
148
### (only used in Smode=3,4,5)
149
###
150
### source [clip]
151
### -------------
152
### If source is defined, LSFmod doesn't sharp more a denoised clip than this source clip
153
### In this mode, you can safely set Lmode=0 & PP=off
154
###    Usage:   denoised.LSFmod(source=source)
155
###    Example: last.FFT3Dfilter().LSFmod(source=last,Lmode=0,soft=0)
