一种基于C++流类操作的图形格式转换方法

A Technique of Transforming Graphic Formats Based on the Operation of C++I/O Stream Classes

运用C ++面向对象流类库技术 ,在开发可视化专用计算程序中简洁有效地实现了图形数据与Auto CAD系统DXF文件之间的相互转换功能 ,从而扩展了所开发程序构建可视化计算模型的能力 ,AutoCAD系统也可以获得绘制更复杂专用图形的数据 ,并给出了应用实例。

By use of the OO technique of C++ I/O stream classes,a method of transforming the grophic formats between the DXF file for Auto CAD system and the graphic file created by the calculating program for a special purpose is simply and effectively realized. Thereby,the ability for the program to create visual calculating models is greatly enhanced,and in this way,the data of creating more complex graphs can also be obtained by AutoCAD system.Finally,real examples using the technique are given.
