= mix =

== Syntax ==
{{int mix(int a, int b, int n, int d)}}

== Arguments ==
:'''a'''
::An integer value to be mixed in.
:'''b'''
::An integer value for the base value.
:'''n'''
::An integer value which controls the mixture.
:'''d'''
::An integer value for the range.

== Return ==
An integer which is a mix of '''a''' into '''b''', based on the position of '''n''' in range [0,'''d'''].

== Description ==
This function calculates how much of  '''a''' will be mixed into '''b''', proportional to the position of '''n''' in the range from 0 to '''d'''. If '''n''' is 0, the value of '''b''' is returned, if '''n''' is equal to '''d''', the value of '''a''' is returned. For any values of '''n''' in between 0 and '''d''', a proportional value is calculated.

This version of the mix function maintains compatibility with the algorithm used by Filter Factory plugins.

== Example ==
<code>
%ffp

ctl(0): "Darken", range = (0, 100)

R = mix(0, r, ctl(0), 100)
G = mix(0, g, ctl(0), 100)
B = mix(0, b, ctl(0), 100)
</code>
