基于FrameBuffer的嵌入式GUI图形抽象层设计
he Design of the GAL Lay in Embedded System Based on FrameBuffer
介绍了在嵌入式Linux操作系统下GUI的图形抽象层GAL的地位及其设计思路，研究了GUI的设计逻辑，着重阐述了如何在中低端设备上利用FrameBuffer来为上一层提供更加通用的图形接口。主要在利用FrameBuffer进行矩形绘制、窗口剪切和存映像空间的操作等方面做了深入的探讨。目前，己经将图形图像部分的研究成果成功运用于中科飞跃电脑绣花机嵌入式系统中。
Introducing the position and blue print of the embedded GUI’S GAL layer．Researching the GUI’S designing logic and focus on expounding how to use FrameBuffer to provide more general interface for upper layer．Main and thorough discussion are on rectangle painting，RAM image operaton and widows’z—order．At present，the fruit of researching has been inplemented in ZhongKeFeiYue Company’s embedded system.
