Annotator, image annotation tool for Elementary OS, released version 1.2.0 today. Here are the new features and how to install guide for Ubuntu users.

Annotator is a free open-source image annotation tool designed for Elementary OS, but also works in other Linux. By releasing version 1.2.0, it now also supports for taking screenshot for full-screen, current window, and selection area.

User can choose to either use UI button or run command line option to take screenshot, though it so far only works on Xorg session. Meaning Ubuntu, Fedora workstation with default GNOME Wayland session need to switch back Xorg from login screen for this feature to work.

• Support for showing and hiding an item’s outline.
• Support for reading an image to annotate from standard input on the command-line.
