摘 要
本文对图形图像处理系统的发展现状和所采用的主要技术进行了详细分析,确定了相应的结构和主要功能,以及实际开发中所采取的技术。系统在Windows XP平台下实现,本课题是采用Visual C++作为编程工具,采用面向对象的程序设计技术实现一个图形绘制和图像处理的应用软件。主要工作分为三类,包括基本图形绘制与编辑、简单的图像处理、图像格式的转换。图形方面主要是设计图形基类,以及继承图形基类的具体图形类。通过对独立功能的封装,可以为今后需要的图形图像的应用奠定基础。系统的优点有:充分体现了面向对象的设计思想,充分运用了C++的特性,比如封装、多态、继承。程序结构清晰,可读性好,程序中做了充分的注释。图形绘制部分避免了传统的switch case的繁琐结构。容易扩充和移植。
最后,对系统进行测试表明,系统功能达到了预期的要求,界面友好,操作简便,运行也较稳定,是一个完成基本功能的图形图像系统。
总体上,本文介绍了系统开发设计的全过程和设计过程中部分代码,也对系统测试的过程进行简单描述,同时对系统中采用的关键技术也作了一些必要的说明,对图像变换的基本原理,图像处理的基本原理和各种图像格式做了详细的阐述。

Abstract
This article has carried on the detailed analysis about graph image processing system development and using of the key technology,identify the corresponding structure and central function, as well as the system adopts technology in the actual development. The system realizes under the Windows XP platform, the topic use Visual C++ as a programming tool, use object-oriented programming techniques to achieve a graphic and image processing software. Major work is divided into three categories, basic drawing and editing graphics, simple image processing, and image format conversion. The graph aspect is designs the graph base class , as well as inherits the graph base class’s specific graph class. Through independent functions encapsulation, for the future’s needs of the graphic images lays the foundation. The system merit has: the object-oriented design’s thought application of the c++ properties, for example encapsulation, polymorphism, and inheritance. Program’s structure is clear, good readability, codes has the full annotation in the program. The graph plan’s part has avoided complicated structure of the traditional switch case. Easy expansion and transplantation.
Finally, system’s testing shows, system’s functions achieve the expected demand, friendly interface, and the operation is simple, also a much stable operation, it has basic functions of the graphic image system.
As a whole, this p
