| Abstract: | The disadvantages of symbol drawing algorithms were analyzed based on the analytic geometry method,and in implementing graphic drawing avere discussed.We realized the ellipse's collection and edit using the geometric transformation method,and the algorithm of computing Bezier curve's and ellipse arc's envelope. |
| Keywords: | analytic geometry method geometric transformation collection edit |
