Gimp Beginner – Straight Line, Circle

Man on cellphone while at the beach.

This tutorial shows you how you can create straight lines and circles with GIMP. Using the shift key a straight line can be drawn, instead of relying on the imprecision of the mouse. A perfect circle can be drawn by setting the aspect ratio of an ellipse.

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

  2. In the upper left hand corner click on File then New… The following window appears.

    I just left the settings at 640×480 pixels because that should be all we need for this tutorial, if you plan on making something more high resolution or of different dimensions you can adjust these settings. Click OK and you will have your work space.
  3. 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.

  5. The thickness and different effects for line creation can be adjusted in the “tool options” Pane on the left hand side located in the tool box. See how adjusting the thickness to 7 made a thinner line?

  6. Now to create a perfect circle! Instead of having the pencil selected, you’ll want to change to the ellipse select tool in the toolbox. To make it a perfect circle, in the tool options part of the toolbox you’ll want to check fixed aspect ratio.

  8. You should be left with a moving dotted line marking where your circle will be.
    To fill the circle with color, leave the circle selected and go up to the top row and choose Select, then choose selection editor.
