中文摘要：

对于速度和重构性要求比较高的激光打标系统来说,一种有效易用的文件格式将起到举足轻重的作用.分析了DXF（drawing exchange format）文件的结构及DXF图形交换文件在基于数字信号处理的激光打标系统中的应用,详述了DXF文件的解析方法,指出了DXF文件在此系统中的优势之处.利用数据交换接口对DXF文件进行二次开发,使得系统获得了比较好的图形处理效果.

英文摘要：

For high requirement of speed and reconstruction for laser marking system,an effective and easy use file format will play a crucial role.The DXF（drawing exchange format） document structure and the DXF＇s application in laser marking system based on DSP（digital signal processing） are introduced.The method of analyzing DXF file is stated in details,and the advantages of DXF file in this system will be pointed out.Using the data exchange interface for DXF＇s secondary development can also make the system to achieve better graphics processing effects.
