What is it ? :

This transform superpose foliums, each of them being slightly rotated and magnified. 

The Parameters :

Mode :
- Mapping : The underlaying image is mapped on the foliums (the "strings"). This mode is especially useful when combined with String-Art Coloring on a pixel formula. It may also be used to texture the strings.
- Color : This mode must be used with a pixel formula and the Gradient coloring in standard.ufm. Each folium is colored with a different color from the neighboring ones. You can choose the number of colors with "Color Number".
- Interlaced Mapping : It works the same as Mapping, but the strings look more intricated. It works well when the shape displayed is rather simple. If more than two strings meet at a point the result may be strange...
- Inerlaced Color : To color interlaced strings.

Folium Type :
- Old : Ignore this type, it is kept for compatibility.
- Cosinus : The folium is of the type r = cos(n*theta), where r and theta are polar coordinates.
- Sawtooth : A sawtooth function is used instead of a cosinus.
It is possible to sum two functions to produce a distorted folium. The functions can be modified independently with the Folium 1/2 parameters.

Folium Power : This modify either the cosinus or the sawtooth function. The look of the folium is changed.

Angle Step : The amount foliums are rotated at each iteration.

Magnification Step : The amount foliums are magnified at each iteration.

Folium 1/2 Order : The order (number of petals) of each folium. Setting different values here produce distorted and irregular foliums.

Folium 1/2 Weight : The relative weight of the two foliums. You must put a value different from 0 here if you want both foliums to have an effect.

Dephasage : The relative angle between the two foliums.

Folium Inner/Outer Bound : Define the boundaries of the folium.

Treshold : The width of the strings.

Color Number : Only for the color modes.

String-Art Coloring

What is it ? :

This coloring draws foliums that can be used to give a more string-like look to images produced with the String-Art transform. It should be used on a pixel formula. You'll likely have to increase color depth in the coloring tab to get something interesting.

The Parameters :

You have to copy the parameters of the transform into the corresponding fields of the coloring in order to get a proper string look. The thickness parameter change the look of the strings.
