Composition Here, these options concern Hue. You can select:

None, Max(x, -), Max(x+d, -), Max(x-d, -), Min(x, -), Min(x+d, -), Min(x-d, -), Max(x+d, -), (x < 0,5), Max(x+d, -),

(0,5 < x), Max(x-d, -), (x < 0,5), Max(x-d, -), (0,5 < x), Min(x+d, -), (x < 0,5), Min(x+d, -), (0,5 < x), Min(x-d, -), (x

< 0,5) and Min(x-d, -), (0,5 < x).

A book could be ﬁlled with results of all these functions. Please, experiment!

Misc. Arrange This drop-down list offers you some other parameters:

Standard, Use average value, Use reverse value, With random power (0,10), With random power (0,1), with gradient

power (0,1), Multiply rand. value (0,1), Multiply rand. value (0,2), Multiply gradient (0,1) and With p and random

(0,1).

Also a book would be necessary to explain all possibilities of these parameters.

Use cyclic range //TODO

Mod. rate With this slider and the input box, you can set modiﬁcation rate from 0.0 to 1.0. Low value results in a lined

pattern.

Env. sensitivity Value is from 0.0 to 1.0

Diffusion dist. Diffusion distance: from 2 to 10.

# of subranges Number of sub-rangers: from 1 to 10.

(P)ower factor With this option you can inﬂuence the Function types using the p parameter. Value from 0.0 to 10.0.

k Parameter With this option you can inﬂuence the Function types using the k parameter. Value from 0.0 to 10.0.

Range low Set lower limit of hue that will be used for calculation. values vary from 0.0 to 1.0.

Range high Set the upper limit of hue that will be used for calculation. Variations are from 0.0 to 1.0.

Plot a graph of the settings By clicking on this large button, you can open a window that displays the graph of hue

present settings.
