How to Download/Install GIMP

  • GIMP is free image editor software for Windows, Mac, and Linux.
  • GIMP works on many computers and you don’t need to buy or install any special programs to use it.
  • GIMP is also available for mobile devices, like Android phones and iPhones.
  • GIMP is called GNU Image Manipulation Program, but GIMP is easier to say.

How to Install GIMP

On Ubuntu 18.04

One useful productivity tool for image manipulation is the GIMP (GNU Image Manipulation Program). It helps you do things like improving image quality, adding effects, and even creating buttons. Even though GIMP is free to use, it doesn’t mean you can’t help pay for development to keep it going. Learn how to install GIMP on Ubuntu 18.04.

The latest version of Ubuntu (from 18.04 onwards) comes with the non-free repository enabled by default. This means that we can now easily install GIMP with just one command:

sudo apt install gimp

This is all that is required to install GIMP, which some of you might already know. But there is more we can do to improve the installation and make it the best and easiest experience. They involve using PPAs, adding more extensions, and installing a theme.

Use PPAs

For previous versions of Ubuntu, PPAs were the main methods of installing software. This was because the only way to install non-free software is to enable repositories.

With 18.04, PPAs are still useful in that they simplify installation via apt software manager. They also allow us to install more recent versions of software.

Basic Editing Using GIMP

GIMP stands for GNU Image Manipulation Program, and it is an open source program that can be downloaded for free.

GIMP is a sophisticated, comprehensive, and powerful package that allows you to create and edit a multitude of graphics and image files.

Although GIMP can be intimidating for first-time users, once you get past the initial learning curve, the program is incredibly powerful.

GIMP can be used to edit photos, create websites, and perform various desktop publishing tasks.

True, GIMP is not quite as user-friendly as Photoshop, but there's nothing stopping anyone from creating incredible work with GIMP.

If you aren't a graphic designer by trade, GIMP is not something you have to use every day. But if you are a creative individual who needs to modify an image, photo, or graphic file here and there, GIMP is a program worth learning and having in your toolbox.

In this tutorial, I will show you how to edit an image with GIMP. We will start with the basics and then move on to more advanced features. By the end of the tutorial, you will have an understanding of how to use GIMP just like a graphic designer.

a) How to Scale or Resize Images

Scaling or resizing an image is a simple task in GIMP. If you want to keep the original proportions of the image, go to the Image menu and select Image with the Scale option. Enter the new dimensions in the dialog box.

To keep the image at the same aspect ratio and have a cropped image, go to the Image menu > Scale Image with the Fixed option. Enter the new dimensions in the dialog box.

To crop an image in GIMP, go to the Image menu and choose Crop. Hold the left mouse button and move the cursor to the desired part of the image, then release the button. You can also enter the dimensions of the cropped area in the dialog box.

b) How to Reduce File Size of an Image

You can use the GIMP’s builtin optimalization functions to reduce image size without losing any visual quality. There are two ways of doing this.

Using the Image Save Options:

From the drop-down list next to “File,” select “Save.” Select the format you prefer for your image ([[jpeg|JPG]], [[[png|PNG]]], or [[[gif|GIF]]].

Now you will see 3 different options available for this image that is the EXIF data, the resolution, and the quality settings. Click on the button options to change from default to optimal.

This will display a list of different resolution and compression settings for the image. Select the optimal option which will provide the best balance between visual quality and image size.

d) How to rotate an image

With GIMP?

Open GIMP and open your image. Now we need to open the rotation tool to do the rotating. Do this by going on Image > Transform Tools > Rectangular to Polar.

Now, draw a rectangle to select the area you want to rotate. Once you’re done, a new window will appear and now lets see how we actually rotate using the tool.

What you’ll need to do is to click on the center of the rotation tool and drag your mouse to select the area you want to rotate. Once you’ve done this, a white circle will appear next to the area you’ve selected.

You’ve to now just rotate your image and a box will appear with your newly rotated image inside it.

Once you’ve hit the green check mark, your image will be rotated. You can see that we are actually rotating the image by 90 degrees by viewing the layer itself. We’ve also selected the entire image and the border is marked with a black line.

Yeah, that’s pretty much it. Go ahead and rotate other images as well.

e) How to flip an image

There are many uses of this technique.

You can flip a vehicle photo so that the background is white, and it can be viewed as on a transparent background. This is the best for camouflage cars and other photo manipulations.

Secondly, you can flip a image on to the reverse side, which can be used in games as well as cartoons.

To do this,.

Open up GIMP and Select the image you want to flip. Press CTRL+A to select the entire image or go to Select>All.

Click on Layer>Flip Layer and select Horizontal.

And your image will be flipped horizontally.

How to Design a logo with GIMP

Designing a good logo can be a long process. It takes time to get a feel for it and to ensure that it's going to be good.

For this tutorial, we'll focus on how you can start from nothing and make something small and nice, from zero to a nice logo. From scratch to a piece of art, in only 15 minutes!

The best thing with GIMP is that it's completely free. An open source software, it's still one of the most powerful software out there right now for digital artists, photographers, and graphic designers alike.

GIMP is a powerful tool, and it can be a bit daunting to learn, but once you get the "hang" of it – you'll wonder how you did anything without it.

First off, we need to install GIMP on our computer, so go ahead and download it. With the set up out of the way, we can get down to business!

Once you have opened the program, we'll start early by selecting a simple background.

Change the color scheme behind your logo by selecting the "Background" tool.

Select an image you like, and change the background color to something that blends nicely with your image. I chose a pastel-blue on the left. You can now start to change the image into your own by using the "Selection" tool.
