<p>PURPOSE:To speed up a replotting by performing the replotting from an image information file when the image information file exists. CONSTITUTION:A system is composed of an input device 22 inputting an image information file, a display device 23 displaying image information, a storage device 24 where the image information file and an image information file are stored and a computer 21 processing a plotting instruction and controlling the display device 23. In the image information file, plural plotting instructions such as the plotting of a circle and the plotting of a square, etc., are described. The matter that the replotting is performed from the storage information of the screen image displayed on the display device 23 is defined as the matter of the highest priority. When this replotting is impossible, a replotting processing is performed from the image information file if the screen data after the reproduction of the image information file is stored as the image information file in a storage device 24. If the image information file is not stored in the storage device 24, the replotting processing is performed from the image information file.</p> |
