PURPOSE:To easily draw a load map having load width by redrawing lines by defining respective intersected points of crossed parallel lines as starting points or end points and erasing respective lines in the parallel line area. CONSTITUTION:After recognizing the setting of width (K), a drawn data forming device 1 erases respective drawn data in a display RAM 2 corresponding to drawn data stacked in a stack RAM 3, respectively reads out the drawn data in each segment, forms redrawn data on the basis of the drawn data including the intersected points, and sequentially writes the redrawn data in the display RAM 2. A drawing device 5 successively reads out redrawn data set up in the RAM 2, forms a segment image corresponding to the contents of the data and develops the formed image on a video RAM 6. The linear image is sent to a display device 7 and intersected points based upon the combinations of two-divided four straight lines (A1-xad, xad-D1, B1-xbd, xbd-D2, C1-xac, xac-A2, C2-xbc, xbc-B2) is displayed on the display device 7. |
