Abstract
In the middle of the 1980’s, with the development of the hardware and computer device, graphic technology and multimedia technology are developing more and more quickly. The contents which computers are able to process extend from the single style of characters to the motivation, sound, video and graphics. Nowadays, with the aid of the Internet, graphic technology and image manipulation are easily bringing into play in our daily life. This paper detailedly describes the generation and the development of the image technology and graphics technology; analyses the relations of the perception medium, representation medium, presentation medium, storage medium and the transmission medium; discourses upon the key point, developing technology and the application prospect. This paper is based on the graphic system, which is developed by the author. It not only dissertates the common procedure, patterns and technical points in developing of the software. But also it discussed the coding, format exchange and data compressing in the graphics. This graphic system exercises lots of design patterns and software engineering methods and solves the problems of cohesion and coupling. It achieves the extendibility and usability of software. All above especially the design pattern are depicted in the paper. Meanwhile the paper introduces the popular formats of pictures and with the analysis of this graphic browsing system; we discuss the framework of this system and some key codes such as BMP converting to AVI. There are 16 main parts in the paper. In each part, we discourse and explain on the history, development and exploitation of the related technology.
Key words：image coding image browsing image compressing design pattern
