ABSTRACT:
For filling the area bounded by a two-dimensional geographic shape, a so-called graphic, with light from a scanning beam, a reduced size graphic is created within the original graphic. The reduced graphic is divided into convex loops by being divided up along a set of lines which extend parallel to a predetermined direction (Y). The respective longitudinal directions of the convex loops are detected, and then, alternate vectors are generated along the respective longitudinal directions of the convex loops. The scanning beam is moved along the vectors on a photosensitive film, thus filling the inner region of the graphic with the traces of the light beam.
