Annotating images in Windows is relatively straightforward. There are many tools available to do it, but on Linux there are not so many options. For my Google Classroom tutorials, I have been using some screen annotation software on Linux called Shutter which works really well and is as fast, if not faster, than some of the Windows variations.
With Shutter, you can take a screenshot of a specific area, a window, the whole screen, or even a website. You can then apply different effects to it and draw on it to highlight different things. Also, importantly, Shutter is free to use and open-source too.
Shutter can do the following:
- Capture a screen, window a specific area or use an existing image
- Draw a straight or freehand line
- Highlight an area
- Draw an arrow, rectangle or ellipse
- Add text
- Crop to a particular size
- Pixelise areas of your screenshot to hide sensitive information
- Censor areas of your screenshot to hide sensitive information
- Export to pdf and every other image format under the sun
Here's a screenshot to illustrate the functionality that this Linux annotation tool offers:
I've found Shutter really simple to use and a real time saver. Thanks to the development team for all their hard work.
