6 ways for taking screenshots in Ubuntu: Shutter, KSnapshot, GNOME Screenshot, scrot, ImageMagick and GIMP.
For those of you who didn’t hear about it before, it’s probably time you have a look at it. Shutter is probably the most powerful screenshot-taking application available for GNOME, including countless features and several useful tools to take screenshots and manipulate them in any way possible.
Shutter is probably the most powerful screenshot application for Linux, and the main reason for this is that it comes with tons of configuration options for the final process of taking a simple screenshot.
After 15 weeks of development, Shutter 0.85 has finally been released. Shutter is a feature-rich screenshot program. You can take a screenshot of a specific area, window, your whole screen, or even of a website – apply different effects to it, draw on it to highlight points, and then upload to an image hosting site, all within one window.
GScrot has been re-launched with new features and a less anatomical name: Shutter :)
