== Description ==


This function, formerly named HistogramAdjust but now named TweakHist, adjusts the histogram of a frame by either equalizing it or by matching with histogram of another image, or with given histogram table of values. [http://www.avisynth.nl/users/vcmohan/modPlus/TweakHist.html Full Description]

 
== Requirements ==
* AviSynth+ r2347 or greater
* Source video: Progressive

 
== [[Script variables|Syntax and Parameters]] ==
:{{Template:FuncDef|TweakHist(''clip'', ''int type, clip mclip, int mf, int limit, int rgb )}}
 
::{{Par2| |clip| }}
::: Input clip.
 
::{{Par2|int||}}
::: Luma value % of maximum.
 
::{{Par2|clip||}}
:::% age of population or cumulative population at this luma value
 
::{{Par2|int|type|1}}
::: Type of process
 
::{{Par2|clip|mclip|dummy clip}}
::: Clip in which image for matching is available.
 
::{{Par2|integer, may be specified for type = 2 option|mf|0}}
::: Frame number on clip for matching.
 
::{{Par2|int|limit|100}}
::: Limit on % of change in value from original for tweaking allowed.
 
::{{Par2|int|rgb|1}}
::: Percentage of deviation from original value of luma to be allowed.
 

== Examples ==

TweakHist()
TweakHist(c,type=2,mclip=mm,mf=26)
TweakHist(c,15,2, 30,12, 50, 33, 90, 12,150,35,200,10, type=3,limit=50)
TweakHist(20,1,150,100,255,110, type=4,limit = 70)

:RGB input. Repeated for each color

TweakHist(limit = 70,rgb = 0)
TweakHist(limit = 70,rgb = 1)
TweakHist(limit = 50, rgb = 2)

Mjb: reverted to what seems to be the last version before Yakub2.X got it mixed up with GBlur
