I基于 VC+的图像处理系统 设计与实现VC + + based Image Processing System Design and Implementation摘摘 要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。程序结构清晰，可读性好，程 序中做了充分的注释。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，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。 关键词：图像处理系统，图像显示,图片格式转换。IIAbstractAbstractThis 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 classs specific graph class. Through independent functions encapsulation, for the futures needs of the graphic images lays the foundation. The system merit has: the object-oriented designs thought application of the c+ properties, Programs structure is clear, good readability, codes has the full annotation in the program. Easy expansion and transplantation. Finally, systems testing shows, systems 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 paper describes the system design process and part of the process of designing code, it made some necessary explanations about key technology in the system, it made the detailed description to image transform of the basic principle, the image processing basic principle and various image formats. Key word: The imagery processing system, image display, image transforms.目 录摘 要 .IAbstract.II 第一章 图像处理系统.1 1.1 概述.1 1.2 系统分析.1 1.2.1 需求分析.1 1.2.2 可行性分析.1 1.3 总体设计.1 1.3.1 项目规划.1 1.3.2 系统功能架构图.2 1.4 系统设计.3 1.4.1 设计目标.3 1.4.2 开发及运行环境.3 1.5 技术准备.3 1.5.1 基本绘图操作.3 1.5.2 内存画布的设计.3 1.5.3 自定义全局函数.4 1.5.4 自定义菜单.5 1.5.5 自定义工具栏.11 1.6 主要功能模块的设计.12 1.6.1 系统架构设计.12 1.6.2 公共模块设计.
