X and Y Scales A low X/Y value will maximize the horizontal/vertical stretch of the texture, whereas a high value will
compress it.
Complexity This controls how the two colors interact with each other (the amount of interplay or repetition).
Random Seed Random Seed controls the random behaviour of the filter. If the same random seed in the same situation is
used, the filter produces exactly the same results. A different random seed produces different results. Random seed
can be entered manually or generated randomly by pressing the New Seed button.
When the Randomize option is checked, random seed cannot be entered manually, but is randomly generated each
time the filter is run. If it is not checked, the filter remembers the last random seed used.
Force Tiling? If you check this, you’ll get a pattern that can be used for tiling. For example, you can use it as a background
in an HTML page, and the tile edges will be joined seamlessly.
Ideal/Distorted This option gives additional control of the interaction between the two colors. Distorted creates a more
distorted interference between the two colors than Ideal.
