摘要
介绍了在嵌入式Linux操作系统下嵌入式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。主要在色彩转换、利用FrameBuffer进行矩形绘制、内存映像空间的操作以及窗口Z序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福建海媚科技的嵌入式KTV系统中,并积极地向其它嵌入式系统中进行移植。
Introducing the position and blueprint 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 color conversion, rectangle painting, RAM image operation and windows'z-order. At present, the fruit of researching has been implemented in FuJian HaiMei company's embedded KTV system, and actively migrated to other embedded device.
