Straight Line Tutorial

Intention This tutorial shows you how you can do straight lines with GIMP, using a feature called the Shift Key. Straight lines are a convenient way to make things that aren't so terribly affected by the imprecision of a mouse or tablet, and to take advantage of the power of a computer to make things look neat and orderly. This tutorial doesn't use Straight Lines for complex tasks; its intended to show how you can use it to create quick and easy line effects.

Red Eye Removal

Editor's note: since this tutorial was written, the Red Eye Removal plug-in has been included in the default GIMP package (see Filters -> Enhance -> Red Eye Removal). This tutorial is still useful if you want to do things by hand. Intention It used to be that the photos with red eye weren't really worth fixing as only cheesy cameras had the flash built in and underneath the red eyes was a crappy photo.

Well, welcome to the future when you can get a pretty good image from a camera with the flash built in. Step 1 I zoomed in on the image, 4:1 ratio, as this is almost pixel by pixel work. Step 2 A long time ago, someone suggested on the gimp-user list that the Layers, Channels and Paths Dialog always remain open while you use GIMP. Step 3 Make certain you have a good brush selected (for this image I used the 5 x 5 fuzzy) Then select the Dodge and Burn Tool. Final ... looking so much better!

Bezier Selections. Text and images Copyright (C) 2002 Tuomas Kuosmanen and may not be used without permission of the author. Intention The Path tool (previously known as Bezier Selection) is a powerful tool in GIMP. The rectangle- and ellipse-selections are not very flexible if you happen to need something more special. And since many of us GIMPers don't have a graphics tablet, it's not so easy to make the mouse pointer move the way you want. The paths can solve the problem by using smooth mathematical curves instead your own shaky mouse trail.

What is it? The Path tool can make complex selections by specifying certain points that are connected together with a curve. Modifying the curves Straight lines alone are a useful thing, but it's not all. Borders On Selections.

Borders On Selections

Intention Since GIMP is an image manipulation program and not a painting program it doesn't include tools to draw shapes like squares and circles. However this doesn't mean you can't paint them, in fact there are some interesting options regarding this subject when it comes to GIMP. The solution is to use the selection stroking capabilities of GIMP. The Basics Tutorial. Text and images Copyright (C) 2002 Jens Lautenbacher and may not be used without permission of the author.

The Basics Tutorial

Intention On this page, the first section of our ever growing (?) Collection of tutorials, I will demonstrate the basic operation you will need to perform over and over again in your life as a computer artist: Generate isolated parts of a picture and combine them with a random background. What we want to achieve in this example is to generate a 3-dimensional text logo flying (and movable) over the background (a simple uni-color layer in our case, but you will easily see that you could use any other (stack of) layers/images instead. Start with a plain white picture, black as the foreground color and open the layer dialog! Adding text Use the text tool to add some text.

Adding colors First of all: Blur the image a bit using <Image> Filters → Blur → Gaussian Blur (a value of 5 may be a good start). Bumpmapping Using the layer mask Now activate the text layer again.

GIMPLite Quickies

Intention So, you have GIMP installed on your computer, you need to make a quick change to an image for some project, but don't want to learn about computer graphics right now in order to get the image changed. Totally understandable. GIMP is a powerful image manipulator with many options and tools. However, it is quick and somewhat intuitive (after a time) for the small jobs as well. A couple of words about the images used here. All you should need to know to start here is how to find your image and open it. Change the Size of an Image (Scale) Problem: you have a huge image and you want to put it nicely for viewing on a web page. The first thing that you might notice is that GIMP opens the image at a logical size for viewing.
