### 2.4. Frihandsutvalet (Lassoverktøyet)

Figur 14.17. Symbolet for frihandsutval i verktøykassa

The Free Selection tool, or Lasso, 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:

- Keep the mouse button pressed (i.e click-and-drag), drag to draw a freehand selection. When the end point is on top of the starting point, release the mouse button to close the selection.

  If you click on the end point, it turns accompanied by a moving cross. Then, dragging enlarges the shape.

- Or release the mouse button and drag to draw a polygonal selection. When the end point is on top of the starting point, click to close the selection.

  Press the Ctrl key and click on the end point: moving the mouse pointer forces moving angles to 15°; so, you can draw horizontal or vertical lines easily.

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.

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.

Du kan finne meir om utvala og bruken av dei i GIMP i kapitlet Utval. Funksjonar som er felles for utvalsverktøya er omtalte i avsnittet Utvalsverktøya.

| Notat
Har du tilgang på digitalt teiknebrett, vil du finne at dette er mykje enklare i bruk saman med lassoen enn datamusa.

#### 2.4.1. Aktivering

Du kan hente fram dette verktøyet anten

- frå biletmenyen via Verktøy → Utvalsverktøya → Frihandslutval,

- ved å klikke på verktøysymbolet i verktøykassa

- eller ved å trykkja på tasten F.

#### 2.4.2. Valtastar

The Free Select tool has key modifiers that affect all selection tools in the same way. See Selection Tools for help with these.

Backspace returns to previous selection step (removes last selection segment), Escape cancels all selection segments.

#### 2.4.3. Å bruke verktøyet

Korleis du kan flytte dette utvalet er nærare omtalt i avsnittet å flytte utval. (Du kan flytte omrisset for utvalet med piltastane, men ikkje med musepeikaren).

#### 2.4.4. Innstillingar

Figur 14.20. Innstillingane for «lassoverktøyet»

Normalt blir innstillingane for det valde verktøyet vist under verktøykassa. Dersom dette ikkje er tilfelle, kan du få tilgang til dei frå biletmenyen via Vindauge → Dialogvindauge → Verktøyinnstillingar som vil opne verktøyinnstillingane for det aktive verktøyet.

Dette verktøyet har ingen spesielle innstillingar utover dei som er omtalte i Del 2.1.2, «Innstillingar».

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.
