屏幕捕获工具：gtkShots
GTKShots 是一个 python/gtk 程序，用来捕捉屏幕截图，可根据配置自动定时捕获，可设置图像精度等选项。可方便用来制作幻灯片和监控桌面活动等。
gtkShots is a python/GTK application to capture screenshots continuosly. It is a hand tool to automatically save the screenshots in a (un)specified period of time, with the possibility to schedule it and to choose options for each screenshot to be saved, such as the size, the parent folder and the time interval between them.
gtkShots could be used for a lot of different aims, for instance to create presentations, to monitor desktop activity, or for any other scope that needs a screenshots sequence.
gtkShots is actually aGUIfrontend to pyshots, my command-line python script to do the same job. Thus, if you need to work on the terminal sessions, you could take advantage of this.
