\"\"<\/a><\/p>\n

Linux has quite a few image annotation tools. “Annotator” is the one designed for Elementary OS with specific features. Here’s how to install it in Ubuntu 20.04<\/b>, Ubuntu 23.04<\/b>, Ubuntu 22.04<\/b> via PPA.<\/p>\n

Without using GIMP image editor, I sometimes uses Shutter<\/a><\/i> to annotate image quickly. As well, Ksnip<\/a> has some useful tools (e.g., drop shadow, invert color and add border) that I use regularly.<\/p>\n

Annotator<\/a> is an app looks kinda like MacOS Preview<\/i>. Like other tools, it allows to add text, rectangle, ellipse, sequence number, line, arrow, blur effect, crop and resize image. What makes it different is the “Magnifier<\/b>” tool. It adds a circle on your image and enlarge the area inside. By right-clicking on the circle, it offers option to change magnification.<\/p>\n

Also, it allows to add stickers, such as industry, mobile and data icons, different type of arrows.<\/p>\n

Install Annotator in Ubuntu:<\/h3>\n

Though the app is designed for Elementary OS, it works on other desktop environments. The developer team provides official package<\/i> as Flatpak. Make sure the flatpak daemon is installed, you may then install the app via command:<\/p>\n

flatpak install https:\/\/appcenter.elementary.io\/com.github.phase1geo.annotator<\/pre>\n
However, the Flatpak package requires separated Elementary OS platform and SDK as run-time libraries. The run-times take about 700 MB<\/b> space while the app itself is only a few hundred KB.<\/p>\n
So I created this unofficial Ubuntu PPA<\/a> for those want to try out this annotation tool with native DEB package. So far, Ubuntu 20.04, Ubuntu 23.04, and Ubuntu 22.04 are supported.<\/p>\n
1. Add the PPA<\/h4>\n
Press Ctrl+Alt+T on keyboard to open terminal. When it opens, run commands to add the PPA:<\/p>\n
sudo add-apt-repository ppa:ubuntuhandbook1\/annotator<\/pre>\n
Type user password, no visual feedback, when it asks and hit Enter to continue.<\/i><\/p>\n
\"\"<\/a><\/p>\n
2. Update package cache<\/h4>\n
Ubuntu 20.04 and higher refresh system package cache automatically while adding PPA, but some Ubuntu based systems may not. To do it manually, run command:<\/p>\n
sudo apt update<\/pre>\n
3. Install Annotator:<\/h4>\n
Finally, install the app using command:<\/p>\n
sudo apt install com.github.phase1geo.annotator<\/pre>\n
\"\"<\/a><\/p>\n
Once installed, search for and open it from start menu (activities overview) and enjoy!<\/p>\n
Remove Annotator & Ubuntu PPA:<\/h3>\n
To remove the Ubuntu PPA, use command:<\/p>\n
sudo add-apt-repository --remove ppa:ubuntuhandbook1\/annotator<\/pre>\n
And remove the annotation tool via:<\/p>\n
sudo apt remove --autoremove com.github.phase1geo.annotator<\/pre>","protected":false},"excerpt":{"rendered":"
