基于 ARM 平台的 X windows
我正在使用基于arm的参考平台。我有 VGA 显示器。如果我想为该平台开发图像查看器软件,我需要学习 X windows 编程吗?请提供您的宝贵意见。这是否涉及帧缓冲区概念? RGDS, 耶吉
I am using arm based reference platform. In that I have VGA display. If I want to develop a image viewer software for that platform, do I need to learn about X windows programming? Kindly provide your valuable inputs. Does this involved frame buffer concepts?

您可以使用 directfb 作为帧缓冲区访问的库(directfb.org),它足以完成此任务,并且性能将优于 x 服务器+窗口管理器(但您必须考虑图形加速,在我的板上只有 xaa (对于特定版本 x.org)驱动程序可用)
you can use directfb as lib for framebuffer access (directfb.org) it will be simply enough for this task and performance will be greater than for x server+window manager (but you must think about graphical acceleration, on my board only xaa (for specific version x.org) driver is available)
