This post introduces some handy screenshot tools for Ubuntu and Windows.
One of the powerful screenshot tool, which not only allow you to take screenshot, of any part of screen, but also allows you to edit the captured image, adding text, hiding private content by pixelating, upload an image to a hosting site and much more.
Gimp is a free and open source image editor which can be used for image manipulation, editing, resizing, retouching etc.
When you’ll open the Gimp GUI, go to File -> Create Screenshot and this menu will appear and you can select the option you want, whether to take screenshot of whole or part of screen.
After this, the snap of image created will be available on the GUI for editing, where you can edit the image, apply effects and so on.
(See the references section for more options for Ubuntu.)
FastStone Capture works on XP, Vista, Windows 7, Windows 8.x and Windows 10.
