| 摘 要： | 对于人脑无法处理的浩瀚如海的各种科学数据,计算机地图制图软件提供了一种直观、实时、可控制的有效处理手段。而制图软件中涉及的图形的无级缩放,图形的平移,图形被破坏后的快速恢复技术在很大程度上决定了该软件的效率与性能。基于此,该文逐一给出了实现这几项技术的比较有效的措施。 |

| Abstract: | For all kinds of science data large as sea that people can not understand with brain,Map Drawing computer software provides an effective and intuitionistic,Real-time ,controllable processing method.These technology of graph's enlarge and diminish without scale,moving,quick restoration after being destroyed decide the software's efficiency and capability.The paper gives all methods about these technology one by one. |
| Keywords: | Enlarge and Diminish without scale Moving Quick restoration Double buffer Double memory copy |
