Abstract
A net of parallel lines is generated with the aid of a computer. The ratio of the width to the spacing of two consecutive lines is equal to r.sub.o. The spacing and width of the lines are successively modulated such that their ratio is equal to r.sub.o. Subsequently, the straight lines can if so chosen be transformed into differently shaped lines or the width of the strokes can be altered in order to reproduce geometrical or artistic images.
