Also commonly referred to as screen grabs, screen dumps, screen caps or screen captures, screen shots are nothing but images taken by a person for recording the visible items that are displayed on a computer monitor, a television or any other type of visual output device that is currently in use. In most cases, it is in the form of a digital image which is captured with the help of a software running on the computer or the operating system running the machine. However, it can even be a shot that is taken by a device or a camera that is intercepting the display’s video output. If you go back into the history of screenshots, the computer operating systems of the 80s era didn’t have any universal built-in capability of capturing the screen shots. There used to be instances in which you could dump the text only screens into text files, but the result would only comprise of the contents appearing on the screen, without any of the graphical features getting preserved.
How screenshots are extremely useful is that you can use them for demonstrating the functionality of a program, or even a particular problem that a user may be experiencing. They can be helpful even in cases where the user needs to show the display output to someone at a remote location or simply needs it for archiving purposes.
Now coming to the AlsaPlayer screenshots, they show this amazing media player in action. Some of the screens that should ideally be captured to show its functionality to the users are: the Tooltip screen, the scope selection and the scope plugin windows, GTK 2 and GTK 1 interfaces, the GTK 2 interface with a large size GTK theme, AlsaPlayer in FVWM Crystal with a custom audio menu and the GTK 2 interface in the FVWM Crystal with a high contrast theme.
