多接口地图符号库的设计与实现

Design and application of the multi-interface map symbol library

本文简要介绍了信息时代地图产品的主要表现形式,并针对地图出版软件系统存在的不足,论述了多接口地图符号库设计和应用的必要性。在分析相关技术的基础上,提出了一种地图符号库多接口的架构方式,实现了针对地图不同输出目标,使用同一套地图符号库,输出GDI、EPS、PDF和SVG等不同文档格式的方法。

The paper briefly introduces the expression forms of the map in the information times. According to the existing problem of the map publishing systems, the paper discusses the necessity of the designing and application of the map symbol library which can output to multiple devices. Base on the analysis of the related technologies, the paper brings forward the architecture, in which a map symbol attached with multiple output interfaces. Using the same map symbol library, users can output the map to different file forms, such as GDI, EPS, PDF or SVG.
