Pixels are stretched on a subpixel precision according to their brightness. The stretching is cumulative for every row or column, which means a pixel offsets all the following pixels on its line. This produces much more organic looking patterns compared to what you get using simple effects like "line stretch". The basic effect is similar to what you'd get on an old analog TV, but all the knobs this filter provides give you much more possibilities!
