I have to replace the nano-X stuff in our linux embedded application and need some replacements for the drawing functions Arc, Rect, FillRect, Ellipse, FillEllipse, Line, Text, DrawImageFromFile . 我必须在我们的linux嵌入式应用程序中替换nano-X的东西，并需要一些替换绘图函数Arc, Rect, FillRect, Ellipse, FillEllipse, Line, Text, DrawImageFromFile 。

Does anyone know of a suitable open source library that I can use to replace these? 有谁知道我可以用来替换这些的合适的开源库？ Ideally it should work with a pixel buffer in 16bit color, so that writing to the linux framebuffer device is possible. 理想情况下，它应该使用16位颜色的像素缓冲区，以便可以写入linux帧缓冲设备。

I thought about libcairo but that is a rather big package fro just this purpose. 我想到了libcairo但这只是一个相当大的包。 The use of Qt 4.7 is planned for the future and I'm sure it contains the necessary drawing functions. Qt 4.7的使用计划在未来使用，我确信它包含必要的绘图功能。 Should I go directly with that? 我应该直接去那吗？

The first library that comes to mind is SDL . 想到的第一个库是SDL 。 Also have a look at GGI (It is much simpler than SDL). 还要看看GGI （它比SDL简单得多）。 FLTK too have a simple 2D/3D interface but it is C++. FLTK也有简单的2D / 3D界面，但它是C ++。

I think you should go directly with Qt (quite a big package too, though) if you're going to use it ; 如果你打算使用它，我认为你应该直接使用Qt（相当大的包装）; it'll be much easier to handle dependancies, and it'll do everything you want. 处理依赖性会更容易，它会做你想要的一切。
