PROBLEM TO BE SOLVED: To make it possible to paint out a closed curve with a simple operation. SOLUTION: The table of the plotting color data 8 of the closed curve data 7, the coordinate data 9 and the paint-out color data corresponding to the optional plotting color data for plotting the closed curve are stored in a ROM 2. A CPU 1 stores the closed curve data 7 in the ROM 2 in a RAM 3 according to a closed curve plotting command and a paint-out command from an input means 5, and plots the closed curve on a CRT 6 based on the plotting color data 8 and the coordinate data 9 through an image output part 4 to paint out the inside of the closed curve with the color data in the table in the ROM 2 corresponding to the plotting data 8 of the closed curve. |
