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 function's
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, Program’s structure
is clear, good readability, codes has the full annotation in the program. 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 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.
