Annotator: An open source application for Linux that can easily add basic annotations to your images

briefly: An exciting and useful annotation tool with additional functions for Linux systems.

There are many tools available for image processing and editing. However, options like GIMP are not necessarily the solution to all problems.

Yes, GIMP offers many features for beginners and advanced users, but learning a few things and applying visual enhancements to any image you want can be time-consuming.

Annotator is an impressive open source tool, you can accomplish many things with just a few clicks.

Install Annotator in Linux

First, Annotator can be used on AppCenter for elementaryOS. But, fortunately, it is a Flatpak package, so you can install it on any Linux distribution.

All you need to do is go to the link of the AppCenter store and download/open Flatpak reference The file uses the software installer. If you need help, we provide more information in the Flatpak guide.

Thinking of using Annotator

Considering that we need to process all kinds of screenshots every day, I think this is very useful for my work. Moreover, the more descriptive, the easier the image will be understood by our readers.

Usually, I use Flameshot as my screenshot tool and use it to add available annotations. Linux can also use other screenshot tools, but I prefer Flameshot because of its quick annotation function.

However, you cannot use Flameshot to add annotations to existing images.

Therefore, Annotator can easily edit existing screenshots or any other images needed.

In my brief use, all its functions worked well, but I wanted to edit and resize the text to make it more intuitive. Other than that, I have no complaints.

If you need to add highlighting/comment to the images on your system, I suggest you give it a try. Let me know your thoughts in the comments below.
