The Free Selection tool, or Lasso, lets you create a selection by drawing it with the pointer.

Since GIMP-2.6, you can use it in two ways. First create the starting point clicking on your image. Then,

In both cases, double clicking on the end point closes the selection with a straight line.

Press Enter or double click inside the shape to validate the selection.

Pressing and releasing the mouse pointer allows you to mix free hand segments and polygonal segments. You can go outside the edge of the image display and come back in if you want to.

The Lasso is often a good tool to use for «roughing in» a selection; it is not so good for precise definition. Experienced users find that it is often convenient to begin with the lasso tool, but then switch to QuickMask mode for detail work.

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.

[Nota] Nota

The Free Selection tool is much easier to use with a tablet than with a mouse.
