### 3.12. Heal

Figura 14.87. The “Heal tool” in the Toolbox

This tool was once described as “The healing brush looks like a smart clone tool on steroids”. And indeed the Healing Tool is a close relative to the Clone Tool, but it is more smart to remove small failures in images. A typical usage is the removal of wrinkles in photographs. To do so, pixels are not simply copied from source to destination, but the area around the destination is taken into account before cloning is applied. The algorithm used for this, is described in a scientific paper by Todor Georgiev [GEORGIEV01].

To use it, first choose a brush with a size adapted to the defect. Then Ctrl-click on the area you want to reproduce. Release the Ctrl key and drag the sample to the defect. Click. If the defect is slight, not very different from its surrounding, it will be corrected as soon. Else, you can correct it with repeated clicks, but with a risk of daubing

#### 3.12.1. Activating the Tool

There are different possibilities to activate the tool:

- From the image-menu: Tools → Paint tools → Heal,

- or by clicking the tool icon: in the Toolbox,

- or by clicking on the H keyboard shortcut.

#### 3.12.2. Key modifiers (Defaults)

Ctrl

  The Ctrl key is used to select the source. You can heal from any layer of any image, by clicking on the image display, with the Ctrl key held down, while the layer is active (as shown in the Layers dialog). If Alignment is set to “Non-aligned” or “Aligned” in Tool Options, then the point you click on becomes the origin for healing: the image data at that point will be used when you first begin painting with the Heal tool. In source-selection mode, the cursor changes to a crosshair-symbol.

Shift

  Once the source is set, if you press this key, you will see a thin line connecting the previously clicked point with the current pointer location. If you click again, while going on holding the Shift key down, the tool will “heal” along this line.

#### 3.12.3. Options

Figura 14.88. Heal Tool options

Normalmente, as opções da ferramenta são exibidas assim que você ativa uma ferramenta em uma caixa localizada abaixo da caixa de ferramentas. Se isso não acontecer, você pode acessar as mesmas através do menu na janela da imagem emJanelas → Diálogos de Encaixe → Opções de ferramentas

Mode; Opacity; Brush; Dynamics; Dynamics Options; Apply Jitter; Smoot Stroke; Hard Edge
  See the Common Paint Tool Options for a description of tool options that apply to many or all paint tools.
Sample merged

  If you enable this option, healing is not calculated only from the values of the active layer, but from all visible layers.

Alignment

  This option is described in Clone tool.

#### 3.12.4. Healing is not cloning

Although the Heal tool has common features with the Clone tool on using, the result is quite different.

Two black spots in the red area. Zoom x800. The source is where the four colors meet. Cloning on the left spot. Healing on the right spot.
