Abstract

PURPOSE:To simplify a graphic extracting work and to execute the labor-saving by extracting racing specified data in accordance with the type of an intersection or a designating graphic in accordance with the instruction of an operator when the intersection is reached during the tracing of the segment of the designating graphic. CONSTITUTION:After a graphic reading device 11 reads the graphic drawn in a graphic displaying object substance, the segment of the special graphic data designated by a tracing processing means 12 is traced, when it reaches the intersection, a tracing direction is determined based on the tracing specified data specified beforehand, and when the intersection is not coincident with the tracing specified data, the tracing direction is determined in accordance with the instruction from the external part and only the segment data of the special type of graphics are traced and extracted in accordance with these determinations. Thus, out of plural types of graphics, the segment of the special type of the graphics can be traced and extracted in a short time and the processing work can be simplified and the labor-saving can be executed.
