 I. DESCRIPTION :
 ================

  SmoothAdjust is a set of 5 plugins to make YUV adjustements:
   - SmoothLevels allows to change levels & gamma with optional limiting
   - SmoothTweak  allows to change brightness, contrast, saturation & hue
   - SmoothCurve  allows to change a plane according to a fixed curve
   - SmoothCustom allows to change a plane according to a custom expression
   - SmoothTools  allows to use all the previous filters in one single pass

  These 5 plugins have a smoothing & dithering algorithm to avoid banding issue.
  Calculations are made in 32bits float to avoid rounding errors and artifacts.
  SmoothAdjust is multithreaded (up to 16 threads) and SSE2/AVX2 optimized.

  For automatic adjustments, see the "AutoAdjust" standalone plugin.



 II. DISCLAIMER :
 ================

  This program is free for non-commercial use only and must be distributed
  in its original form without any modification, including this documentation file.
  This program is provided as-is in the hope it will be useful but 
  without any warranty, including any hypothetical damages or issues.

  The official home page is "http://forum.doom9.org/showthread.php?t=154971",
  it always contains the latest version of this program.
  This page acts as the official support center, also the author is reachable
  through his member page: "http://forum.doom9.org/member.php?u=131032".

  This plugin has required a lot of work and hundreds of coding hours, so if you like
  it and feel the need to reward or inspire the author then please consider donating.
  Donations are a fast, easy and secure operation through Paypal: simply follow the
  link into the "Donate.url" shortcut (you do not need a Paypal account to donate).
  All donations will be very useful and I thank in advance all the generous people,
  also if you are on the doom9's forum please specify your nickname when donating.



 III. INSTALLATION :
 ===================

  There are different versions of SmoothAdjust to suit all installations of Avisynth:
   - x86 builds are for Avisynth 32bits
   - x64 builds are for Avisynth 64bits



 IV. REQUIREMENTS :
 ==================
   
  - Avisynth v2.6.x or Avisynth Plus
  - YUV Planar (Y8, YV411, YV12, YV16, YV24)
  - 8bits or 16bits (MSB/LSB)



 V. MULTITHREADING :
 ===================
  SmoothAdjust is internally multithreaded with official Avisynth version. 
  If AvisynthPlus or AvisynthMT is detected, internal multithreading is automatically disabled
  even if external multithreading isn't used (this can be reactivated in parameters).

  SmoothAdjust is designed to work with external multithreading, so fastest MT mode can be used.
  With AvisynthPlus, this plugin is a MT_NICE_FILTER (automatic register, no need to call SetFilterMtMode).
  With AvisynthMT, SetMtMode(1) must be called before SmoothAdjust.



 VI. USAGE :
 ===========

  - SmoothLevels( input_low, gamma, input_high, output_low, output_high, chroma, limiter, TVrange, preset,
                  Lmode, darkSTR, brightSTR, Ecurve, Ecenter, protect,
                  interp, dither, HQ, useMT, useOPT, debug, screenW, screenH, scale )

  - SmoothTweak( brightness, contrast, saturation, hue1, hue2, limiter, TVrange,
                 Lmode, limitSTR, Ecenter,
                 interp, dither, HQ, useMT, useOPT, debug, screenW, screenH, scale )

  - SmoothCurve( Ycurve, Ucurve, Vcurve, mode, limiter, TVrange,
                 interp, dither, HQ, useMT, useOPT, debug, screenW, screenH, scale )

  - SmoothCustom( Yexpr, Uexpr, Vexpr, limiter, TVrange,
                  interp, dither, HQ, useMT, useOPT, debug, screenW, screenH, scale )

  - SmoothTools( filename,
                 interp, dither, HQ, useMT, useOPT, debug, screenW, screenH, scale )

  - SmoothLevels16(...), SmoothTweak16(...), SmoothCurve16(...), SmoothCustom16(...), SmoothTools16(...) for 16 bits

Last version (2015/11/15): SmoothAdjust v3.20

Old version (for Avs2.5 or WinXP or Wine): SmoothAdjust v2.62


If you really like this filter, please consider donating...
