Knitting pattern and the like having pattern fields of different characteristics adapted for being scanned line-by-line and point-by-point, and an electro-optic scanning device for use therewith. The pattern is provided with parallel transverse trace tracks spaced at equal intervals, and with scanning pattern lines alternating with the trace tracks and parallel thereto. Each of the trace tracks consists of longer and shorter fields which alternate with each other and which have different optical characteristics, for example, different light permeability or different degrees of light reflection. |
