Gimp Beginner – Straight Line, Circle

This tutorial shows you how you can create straight lines and circles with GIMP (Gimp – Open source image retouching and editing tool.). A straight line can be drawn using the Shift key, instead of relying on the imprecision of the mouse. A perfect circle can be drawn by setting the aspect ratio of an ellipse.

Let’s start by creating a new file. Open up Gimp, A window titled GNU Manipulation Program as seen below should pop up.

Let Us Begin With The Straight Line

Leave the settings at 640×480 pixels since that should be all we need for this tutorial, if you plan on making something higher resolution or of different dimensions you can adjust these settings. Click OK and you will have your work space.To draw a straight line click on the pencil Icon in the toolbox, place the pointer over the white surface and place a dot where desired.

The thickness and other effects for line creation are adjusted in the Tool Options” pane on the left hand side in the tool box. See how adjusting the thickness to seven made a thinner line?

The Circle Is Just As Easy

Now to create a perfect circle! Change to the ellipse select tool in the toolbox, instead of the pencil, otherwise you will draw another line. To make it a perfect circle, in the tool options part of the toolbox you’ll want to check fixed aspect ratio.

A moving dotted line, marking your circle, tells you that you created the circle correctly. Leave the circle selected and go up to the top row and choose Select, then choose Selection Editor, this will fill the circle with color.
