基于CorelDRAW的制图要素符号化研究

摘要

Mapping elements'symbolization is a process that taking advantage of various map symbols to visually express the spatial position,distribution characteristics,quantity,quality and other basic characteristics of ground features.CorelDRAW earns super favor among mapping personnel for its strong editing function to graphics,characters and vector lines,which especially plays an important role in elements' symbolization.The paper expands theoretical illustration on mapping elements' symbolization in point,line and shape aspects.In the meanwhile,based on CorelDRAW X5 and its Macro Editor,it cites CorelDRAW 15.0 Type Library and carries out secondary development,realizing the point symbol replacement at nine positions,the realization of I-shaped boundary symbol and region filling with user-defined point symbols.Undoubtedly,these technical innovations not only improve mapping efficiency but ensure artistic mapping contents.%制图要素符号化是利用形式多样的地图符号,对地物的空间位置、分布特点以及数量、质量等基本特征进行可视化表达的过程.CorelDRAW极强的图形、文字及矢量线划编辑功能颇受制图人员青睐,尤其在要素符号化工作中扮演着重要角色.文章从点、线、面三个角度对制图要素符号化进行了理论探析,并基于CorelDRAWX5及其宏编辑器,引用CorelDRAW 15.0 Type Library控件进行了二次开发,实现了点状符号的九位替换、工字型国界符号的生成和自定义点符号的面域填充,不仅提高了地图制图效率,而且确保了图面内容的美观性.
