The Paint.NET inspired bitmap image drawing and editing software Pinta 2.0 was released a few days ago.

Pinta is finally ported to GTK3, though GNOME now is shifting to GTK4. Along with .NET6 the UI now looks more native in Ubuntu:

  • The tab bar looks more native in GNOME.
  • Use the standard GTK font chooser (pop up dialog) instead of drop-down selection for Text tool.
  • Change several tools to use spin buttons rather than editable combo boxes.
  • The position / selection information, zoom, and the color palette now moved to bottom status bar.
  • The tool palette displays in a single column with “>” button in the bottom to reach more tools.
  • The “Open Recent menu” is gone. And, “Add-ins” has been removed.
  • The color palette now remember recently used colors.
  • The primary and secondary palette colors are now saved in the application settings
  • And the canvas can now be panned by clicking and dragging with the middle mouse button

How to Install Pinta 2.0 in Ubuntu Linux:

Pinta is available to install as 3 different package formats: native DEB, universal Flatpak and Snap. You may choose one to install or install all of them side by side (will cause duplicated app icons).

Option 1: Snap

The Pinta snap package is available to install from Ubuntu Software. And, if you already install the package before, it should now update to v2.0 automatically.

Option 2: Flatpak

Like Snap, Flatpak is another universal package format runs in sandbox. It installs updates automatically but takes more disk space.

Ubuntu user may install Pinta as Flatpak by running the commands below one by one:

  • Install Flatpak daemon:
    sudo apt install flatpak
  • Install Pinta from flathub repository:
    flatpak install

Option 3: Classic Deb package:

For those prefer the native deb packages, Pinta has a stable PPA though NOT updated at the moment.

User may press Ctrl+Alt+T on keyboard to open terminal, and run command to add the PPA:

sudo add-apt-repository ppa:pinta-maintainers/pinta-stable

Once the PPA is updated, Pinta 2.0 will be available to upgrade along with other system packages in Software Updater.

Uninstall Pinta:

To remove Pinta Snap and Deb packages, use Ubuntu Software or run one of the commands below:

sudo snap remove --purge pinta
sudo apt remove --autoremove pinta

And remove the PPA using “Software & Updates” tool under “Other Software” tab.

For the Flatpak package, use command:

flatpak uninstall --delete-data com.github.PintaProject.Pinta

And clear useless run-time libraries via flatpak uninstall --unused.

After a few beta testing releases, the popular digital painting software Krita 5.0 is finally out with lots of new features!

How to Get Krita 5.0:

Krita is available to install via Ubuntu PPA and Flatpak package. As both are not updated at the moment, user may download the AppImage from the link below:

AppImage is a single package that may run directly to launch the app (like EXE for Windows). Just right-click and add executable permission in file ‘Properties -> Permissions’ dialog, then click run the AppImage to start the Krita.

Free and open-source clone of Paint.Net 3.0, Pinta, released version 1.7.1 a few days ago with improvements and bug-fixes.

The release is the final version based on GTK2, as the GTK3 / .NET 6 version is nearly ready!

Pinta 1.7.1 is a small release with minor new features to improve user experience. For image with large resolution (or zoomed in), you may use mouse wheel to scroll up / down. Now by holding Shift + mouse wheel, the canvas can be scrolled horizontally.

Same to GIMP, user may now press X to exchange background and foreground palette colors quickly in Pinta since v1.7.1. And, zooming in and out can now be done without pressing the Ctrl key

The release also improved the pop-up dialog when you trying to open an unsupported file format. The file open dialog by default shows only supported images, including ani, png, bmp, jpg, gif, icns, ico, jpeg, ora, pnm, qtif, svg, tga, tif, tiff, xbm, xpm. If you chose show “All files” and selected an unsupported file, it will prompt that file not support and show you all supported file formats.

Error when opening unsupported file and display all supported formats

Other changes in Pinta 1.7.1 include:

  • Use arrow keys to move per pixel in Move Selected Pixels and Move Selection tools
  • Use Shift to constrain to a uniform scale when scaling using Move Selected Pixels tool
  • Text in ‘About’ is selectable to copy version for use to report bugs.
  • Improve handling of memory allocation failures for large images
  • And various bug-fixes.

How to Install Pinta 1.7.1 in Ubuntu Linux:

Option 1: Install Pinta via Snap:

The app is easy to install in Ubuntu using the Snap package, by simply searching for and installing from Ubuntu Software (Snap Store):

Pinta Snap app in Ubuntu Software.

Option 2: Install Pinta via Ubuntu PPA:

NOTE: the PPA package crashes randomly due to outdated Mono library in Ubuntu. It’s highly to upgrade mono library if you want to install Pinta in native deb package.

The app has an official Ubuntu ppa that contains the latest packages for Ubuntu 18.04, Ubuntu 20.04, Ubuntu 21.04, and Ubuntu 21.10 so far.

Firstly, press Ctrl+Alt+T on keyboard to open terminal. Then run command to add the PPA:

sudo add-apt-repository ppa:pinta-maintainers/pinta-stable

Secondly, run command to update system cache if you’re still running Ubuntu 18.04:

sudo apt update

Finally, install Pinta via command:

sudo apt install pinta

Or, upgrade the app if an old version present in your system using Software Updater:

In addition, Pinta is also available to install as Flatpak package. Check in Flathub if you’re interested in it.

How to Remove Pinta from Ubuntu:

To remove Pinta installed via PPA package, run command in terminal (Ctrl+Alt+T):

sudo apt remove --autoremove pinta

And remove the PPA either via ‘Software & Updates‘ utility under Other Software tab, or by running command:

sudo add-apt-repository --remove ppa:pinta-maintainers/pinta-stable

For Pinta snap package, remove it either via Ubuntu Software or by using command:

snap remove --purge pinta

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, Ubuntu 21.10, Ubuntu 22.04 via PPA.

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

Annotator is an app looks kinda like MacOS Preview. 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” 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.

Also, it allows to add stickers, such as industry, mobile and data icons, different type of arrows.

Install Annotator in Ubuntu:

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

flatpak install

However, the Flatpak package requires separated Elementary OS platform and SDK as run-time libraries. The run-times take about 700 MB space while the app itself is only a few hundred KB.

So I created this unofficial Ubuntu PPA for those want to try out this annotation tool with native DEB package. So far, Ubuntu 20.04, Ubuntu 21.04, Ubuntu 21.10, and Ubuntu 22.04 are supported.

1. Add the PPA

Press Ctrl+Alt+T on keyboard to open terminal. When it opens, run commands to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/annotator

Type user password, no visual feedback, when it asks and hit Enter to continue.

2. Update package cache

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:

sudo apt update

3. Install Annotator:

Finally, install the app using command:

sudo apt install com.github.phase1geo.annotator

Once installed, search for and open it from start menu (activities overview) and enjoy!

Remove Annotator & Ubuntu PPA:

To remove the Ubuntu PPA, use command:

sudo add-apt-repository --remove ppa:ubuntuhandbook1/annotator

And remove the annotation tool via:

sudo apt remove --autoremove com.github.phase1geo.annotator
