Parameters

type

Flag that indicates the function to be applied.

factor

Value that is used as an amplitude factor when squaring, taking the logarithm of or taking the square root of the color values and as a frequency factor when taking the sine or cosine of the color values. The factor value is divided internally by different amounts, according to the type of the function being used. These amounts are as follows:

if the type parameter is set to:	then the factor parameter will be divided by:
Square	10000 internally
Logarithm	10 internally
Square Root	10 internally
Sine	100 internally
Cosine	100 internally

Only positive values are accepted.
