“Shutter: This is a very powerful and feature-rich tool for
taking screenshots. Written in GTK and blending well in GNOME,
Shutter offers just about anything you would ask from such an
application: timer, screenshots of whole screen, windows, widgets,
a quick and easy-to-use editor for fast retouching or pointing out
certain aspects of the image, support for plugins,
exporting/importing and saving to PNG, JPG or BMP. Definitely a
winner in my opinion.“GNOME Screenshot: This is the default screenshot application
that comes with the GNOME desktop environment, offering a very
basic graphical interface. It’s triggered by pressing Print Screen,
and by default it will take the screenshot of the whole
screen.”
