基于Elastos操作系统的图形引擎的设计与实现

Design and Realization of Graphics Engine Based on Elastos Operating System

Elastos图形系统Vinci是Elastos操作系统的一个子系统,负责在屏幕上绘制像素、文本和用户界面(包括窗口、菜单、对话框)等。图形引擎的体系结构决定了此系统的简易性、灵活性、效率和稳定性,所以它的设计又显得至关重要。分别介绍了基于Elastso操作系统的图形系统Vinci、此图形引擎的设计需求,在此基础上根据图形系统的引擎功能设计需求结合Elastos图形系统Vinci自有的特点,实现了Vinci引擎的设计,使得基于Vinci系统的Elastos操作系统可以完成各种各样的操作。

Elastos graphics system Elastos Vinci is a subsystem of the operating system, responsible for drawing pixels on the screen, text and the user interfaee （including windows, menus, dialog）. Graphics engine determines the architecture of the same easy - to- use, flexibility, effeiteiency and stability, so it is essential. This paper introduces the graphics - based operating system Elastso Vinci systern, the design of the graphics engine demand,and according to graphics system and the engine function design demand and Elastos graphics systern Vinci＇s own characteristics,realize the Vinei engine design which makes he operating system Elastos based on Vinci system can canpleted a wide range of operations.
