主人是发生发展的地方，不应被视为稳定。使用标签进行稳定版本。
窗口/Linux/Mac
跨平台屏幕和窗口捕获库
Linux：sudo apt-get安装libxtst-dev libxinerama-dev libx11-dev libxfixes-dev
图像格式为RAW BGRA每个像素32位。 Alpha未使用newframe，除了使用该空格的地方，并且使用了framechang！
如果您要使用A for循环[A，R，G，B]，[A，R，G，B]，[A，R，G，B]，则数据存在。有关为什么这是在此处查看帖子的原因

同样，不要为您不在乎的事件定义回调。如果这样做，假设您需要信息，则图书馆将进行额外的工作。
库拥有所有图像数据，因此，如果您想在回调完成后出于自己的目的使用它，则必须将数据复制出来！
每个监视器或窗口将以自己的线程运行，因此没有阻塞或内部同步。如果您要捕获三个显示器，则一个线程正在捕获每个监视器。
调用start_capturing后，无法更改对ICAPTURECONFIGURATION的调用。您必须销毁它并重新创建它！
可以随时从任何线程更改isCreencaptureManager的呼叫，因为所有呼叫都是线程安全的！
