2.4. Seleção Livre (Laço)

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

You can use this tool in two ways. First create the starting point by clicking on your image. Then:

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

In polygonal mode, this selection is a preliminary selection; ants are marching, but the small yellow circle is still present: you can copy the selection and, pressing the Backspace key, you return to the previous selection step (re-open the shape), and you can edit the selection.

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.

Free Select 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 Free Select tool, but then switch to Quick Mask mode for detail work.

Since GIMP-2.10.12, selection modes work differently. Marching ants come with a continuous line, meaning that the selection is not validated yet and that you can still change the selection shape (mouse pointer comes with the Move icon). But you can't use (holding it pressed) Shift, Ctrl yet. You have to hit the Enter key. Then you can use (holding them pressed) Shift to add a selection, Ctrl to subtract a selection, Shift + Ctrl to intersect two selections. When you are satisfied with your changes, hit Enter key to validate the selection.
