# LimitedSharpen() ( a modded version, 29 Oct 2005 )
#
# A multi-purpose sharpener by Didйe
#
#
# 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

Как сделать цветокоррекцию, чтобы лебедь и борода у мага стали не таким синим а чуток белее...

И как сделать так, чтобы краски по контурам не размывались..

теперь если брать чтобы ширина\высота была кратно 8
ширина: 696 или 704
высота: 408 или 416
--
если чтобы было кратно 16 то выходит:
ширина: 688 или 704
высота: 400 или 416
