PURPOSE:To correct a defect in which a breaking section is long by connecting each end point, when each end point of two folding lines exists within the prescribed distance and angle, and extending the end point to a different folding line, when the other end point does not exist in the vicinity of the end point and the different folding line exists. CONSTITUTION:By an extracting part 1, a folding line A0A1 including an end point A1 are extracted from a data table, and by a retrieving part 2, the other end point in the vicinity of the end point A1 is retrieved from the table. Since different end points B0, C1 and D0 exist in the vicinity of the end point A1, inner angles thetaB, thetaC and thetaD made by the folding line A0A1, and straight lines A1B0, a straight line A1C1 and a straight line A1D0 are calculated by an interior angle, and their sizes are compared. Since thetaB takes the minimum value, a generating part 4 generates a new folding line A1B0. With regard to a breaking defect part composed of the end points C1, D0, as well, a new folding line C1D0 is generated in the same manner, and the breaking defect is corrected. Subsequently, with regard to a folding line E0E1, since other end point does not exist in the vicinity of an end point E1, and other crossing folding line F0F1 exists, a point E is changed for an intersection M by a changing part 6 and a corrected graphic is obtained. |
