- # LimitedSharpen() ( a modded version, 29 Oct 2005 )
- #
- # A multi-purpose sharpener by Did閑
- #
- #
- # Changes in this mod:
- #
- # - RemoveGrain >= v0.9 IS REQUIRED!!
- # ==================================
- #
- # - Smode=4 / sometimes does the magic ;-)
- # - a separate "undershoot" parameter, to allow for some line darkening in comic or Anime
- # - Lmode=3 / on edges, limited sharpening with zero OS & US. On not-edges, limited sharpening with specified OS + LS
- # - "soft" acts different now: no more boolean true/false, but instead integer 0 - 100 (or -1 -> automatic)
- #instead of blurring before finding minima/maxima, it now softens the "effect-of-sharpening"
- # - edgemode=-1 now shows the edgemask. (scaling still not implemented :p )
- #
- ## - MODIFIED version using MaskTools 2.0

:o 我真是好人:o 其实LimitedSharpen不就是么 LSF不过是快那么一点而已:o
