运用OO方法设计统计符号库的理论探讨

Theory Discussion of Statistic Symbol Library Designing Based on Object oriented Method

统计符号库的设计与实现是符号库软件的难点，一直没有得到较好的解决，制约着统计地图制图软件的开发和实用化。本文首先分析了符号绘制的常用方法及其应用于统计符号库设计的局限性，进而基于ＯＯ方法提出了统计符号库设计的一种新方案。

Statistic symbol library designing and realizing are very difficult, which hedges the software development and implementation of statistic cartography. Firstly the old methods and their disadvantage in statistic symbol library designing are retraced and reviewed. Secondly, a new method of statistic symbol library designing based on object oriented theory is presented. Lastly several difficult parts and their solutions are given.
