DXF到SVG图元转换关键问题分析

Analysis on key issues about conversion from DXF to SVG metafile

为了实现矿图的重新发布,通过分析AutoCAD数据格式(DXF文件)和SVG格式标准,建立DXF文件中的实体和SVG中的元素之间的对应关系.详细分析了关键的复杂图元对象(文字,多线)以及非图元对象(坐标系,颜色)到SVG的转换,以便更方便地运用到WebGIS的矿图发布.编程测试证明,重新发布的矿图与原图基本相同.

In order to re-release Mine maps,the AutoCAD data formats（DXF files）and SVG format standard are analyzed,and the corresponding relationship between the entities of DXF files and SVG elements is established.Then the conversion from the key and complex metafile objects（textl,ine）and non-metafile objects（coordinates,color）to SVG is analyzed at length.By doing so,it can be more easily applied to the map releasing of WebGIS.At last,programming is made to testify that the re-released mine map is basically same with the original mine map.
