PURPOSE:To attain proper plotting by approximately correcting the calculated angle of a circular arc. CONSTITUTION:When an angle on the circumference of a linear pattern is calculated, dot data on a circumference necessary for plotting in an image memory 8 are calculated from the angle and the bit information of a linear pattern obtained from a linear pattern storing part 4. The position of dot data setting up a bit to '1' is calculated in the image memory 8. The outline of a circle based upon the linear pattern is plotted in the image memory 8 based upon the data. The bit data developed to bits in the image memory 8 are trans ferred to a printer 20 through a printer interface 9 and the linear diagram of the circle is printed out by the printer. |
