The Ellipse Selection tool is designed to select circular and elliptical regions from an image, with high-quality anti-aliasing if you want it. For information on selections and how they are used in GIMP see Selections; for information on features common to all selection tools see Selection Tools.
This tool is also used for rendering a circle or ellipse on an image. To render a filled ellipse, create an elliptical selection, and then fill it using the Bucket Fill tool. To create an elliptical outline, the simplest and most flexible approach is to create an elliptical selection and then stroke it. However, the quality of anti-aliasing with this approach is rather crude. A higher quality outline can be obtained by creating two elliptical selections with different sizes, subtracting the inner one from the outer one; however this is not always easy to get right. The command → makes it easy.
The Ellipse Selection Tool can be activated from an image
menu as

or from the keyboard using the shortcut e.

See Selection Tools for help with modifier keys that affect all these tools in the same way. Only effects that are specific to the Ellipse Select tool are explained here. |
Pressing the key after starting your selection, and holding it down until you are finished, causes your starting point to be used as the center of the selected ellipse, instead of a corner of the rectangle that may contain it. Note that if you press the Ctrl key before starting to make the selection, the resulting selection will be subtracted from the existing selection.
Pressing the Shift key after starting your selection, and holding it down until you are finished, constrains the selection to be a circle. Note that if you press the Shift key before starting to make the selection, the resulting selection will be added to the existing selection.
Pressing both keys combines the two effects, giving you a circular selection centered on your starting point.
