摘要：The invention relates to the graphic reproduction of symbols on an imagingsurface. These symbols can be controlled as regards position and/or scale. They arereproduced as successions of brightness values arranged in image lines. As a result of theuse of brightness values between levels occurring in an ideal brightness profile of thesymbol (for example, only black and white), high-resolution details are reproduced. Inaccordance with the invention, boundaries between successive image lines are used toreproduce transitions between the brightness levels as sharply as possible.
