Greenshot
Greenshot is a free and open-source screenshot program for Microsoft Windows. It is developed by Thomas Braun, Jens Klingen and Robin Krom and is published under GNU General Public License, hosted by GitHub. Greenshot is also available for macOS, but as proprietary software through the App Store.
Greenshot's feature set mainly targets project managers, testers and developers.
It is used to create full or partial screenshots. The captured screenshot can be annotated and edited using the built-in image editor before exporting it either to an image file, email attachment, printer or clipboard.
By March 2012, Greenshot was available in 33 languages; most of the translations have been contributed by users.
Features
Screenshots
Greenshot offers several modes for creating a screenshot:"Capture region" allows to select an area of the screen by dragging a green rectangle to the desired position and size.
"Capture last region" is used to re-capture exactly the same area that was captured before.
"Capture window" creates a screenshot of the active or a selected window.
"Capture fullscreen" captures the complete screen.
"Capture Internet Explorer" allows creating a scrolling capture of websites that are larger than the browser window when opened in Internet Explorer.
Image editor
If the user needs to add annotations, highlightings or obfuscations to the screenshot the built-in image editor can be used. Greenshot's image editor is a basic vector graphics editor; however, it offers some pixel-based filters.It allows to draw basic shapes and add text to a screenshot. Special filter tools are present to highlight text or an area, as well as obfuscating tools which can be used to wipe out sensitive data from a screenshot.
Each tool comes with its set of settings, e.g. line color and thickness or an option to drop a shadow.
