Learn how to Set up and Use GIMP on Ubuntu

One thing that users really love about Linux is the open source development culture. Even if you can't afford to spend your money on quality closed source software, you don't have to settle for inferior products. The open source community ensures this by developing and publishing free apps.

One such app is GIMP, short for GNU Image Manipulation. With the GIMP installed on your Ubuntu machine, you can do all if not most of your picture-related tasks – including everything from super simple things like taking screenshots and cropping pictures to more sophisticated things like creating pictures, animation , Scripting support and more.

How do I install GIMP on Ubuntu?

There are many ways to install GIMP on Ubuntu. Let's go through each one one at a time.

Install GIMP through the terminal

Every Linux user knows that the command line is the best way to control a machine. So let's start with this method first. Start the terminal from the application menu or press the Ctrl + Old + T Keyboard shortcuts. Then type the command from below and press Enter:

sudo snap install gimp

Note that the above command assumes that the Snap Package Manager is already installed on your system. However, if you don't, run this command:

sudo apt update
sudo apt install snapd

After installing the snap package, run the command to install gimp again.

Install GIMP from the Software Center

If you're still learning the ins and outs of the terminal or just don't like it, you can use the GUI instead. Fortunately, gone are the days when you only had to use the command line if you wanted to work on a Linux-based system.

Now you can just use the Ubuntu software application to install new software. To start, launch Ubuntu Software from the Applications menu and look for & # 39;gimp. & # 39; Click on To install to download the GIMP package and the system will get it up and running in no time.

Install GIMP on Ubuntu with Flatpak

Flatpak is a package management and software development utility for the Linux environment. Flatpak and Snap are similar package managers, and like Snap, you can use Flatpak to install GIMP on Ubuntu as well.

If Flatpak is not installed on your computer, run this command:

sudo add-apt-repository ppa: alexlarsson / flatpak
sudo apt update
sudo apt install flatpak

After you are done with the installation, add the Flathub repository to Flatpak:

flatpak remote-add flathub https://dl.flathub.org/repo/flathub.flatpakrepo

The only thing left now is a quick restart so that everything runs smoothly.

After rebooting, install GIMP using this command:

sudo flatpak install flathub org.gimp.GIMP

And that's all about the different ways to install GIMP on Ubuntu. Now let's see how you can use GIMP in creative ways on your computer.

Creative ways to use GIMP on Linux

The current version of the GIMP is a force to be reckoned with. With features like animation, screenshot capture, and more, GIMP is one of the best Photoshop alternatives for those on a budget. In addition, it is available for a variety of platforms such as Windows, macOS, Linux, etc.

As said by the GIMP developers themselves, "Whether you are a graphic designer, photographer, illustrator, or scientist, GIMP gives you sophisticated tools to get your job done."

Let's go through some use cases of GIMP on Ubuntu.

Take screenshots with the GIMP

If your job is to give presentations or explanations to an audience, at some point you will need screenshots. GIMP will come in handy when you do this. To record one now, start the app and select the option in the main menu File> Create> Screenshot.

A new dialog box will appear to take the screenshot. Select the options you want there.

By doing Area Section you need to select the type of screenshot you want. You can choose between a screenshot of the entire screen, a screenshot of a single window, or, if you prefer, just a screen clip of a specific region.

There is also a Delay and Color profile Section in which you can tinker with the time delay of the screenshot or the settings.

Scaling and resizing images

Resizing or scaling images is a common requirement for many people who work with images on a daily basis. GIMP can help you with that.

Open the image you want to edit with GIMP. Now click on in the main menu Image> Scale Image.

In the next dialog box, change the image size by tinkering with the height, width, X resolution, and Y resolution. You can adjust the quality to the setting you want. Then click on frame to complete the changes.

After you're done editing, click File> Export As to save the file in the format you want.

Change the image size

You can also reduce the size of an image. Open any image you'd like to reduce in size and select File> Export As.

Now select the picture you want to resize and set a new name and file type. You should choose either JPG or PNG as these are lossy image formats. This means that if you reduce the image size, you will lose little in image quality.

Click on export. In the new dialog box, reduce the quality of the image to optimize its original size. When you do this, the file size will be reduced. And when you know what you're doing, click Expanded options to tinker with further picture settings.

Then click on export to complete the process.

Cropping an Image Using GIMP

At other times, you may only need a specific region or part of an image. Again, GIMP can help you through the cropping tool. To crop an image, select the Crop tool from the tool palette. Now all you have to do is grab the area by dragging your mouse over it.

Left click anywhere on the image and drag the mouse over the area you want to crop. Left-click the selected region again and GIMP will crop the image for you. Finally choose File> Export As to save your cropped picture.

Create a circular image

Circular images are mainly used for avatars on social networks. However, you may need them for your personal use; maybe for your blog posts or something like that.

Select an image, then click Layer> Transparency. Choose there Add alpha channel.

Right-click on the in your toolbox Rectangle selection Tool and click Ellipse selection. Now go to the window Tab and select Dockable Dialogs> Tool Options.

To set a perfect circle, use the Firmly Option, choose the Aspect ratio and enter 1: 1. Select the area you want to crop, then press Ctrl + I to reverse the selection. You have now selected all the parts that you want to exclude. Press the Clear Button to remove all selected areas.

Now save the image in PNG format. PNG is currently the only format that supports transparent images. So this is a minor caveat to deal with when using the GIMP.
