PURPOSE: To improve efficiency for plotting a wide line by deciding the plotting of the wide line when the wide line to be plotted on a printer or a display is horizontal or vertical. CONSTITUTION: A display/printer control panel 20 controls a display monitor 24 and a laser printer 30 while using a graphics processor, and this graphics processor has a line instruction command for plotting the wide line. In this case, it is decided whether the wide line L to be plotted on the printer 30 or the display is horizontal or vertical and when the wide line L is horizontal or vertical, the wide line L is plotted on the printer 30 or the display. Thus, efficient graphic processing is enabled. |
