La herramienta recortar se usa para recortar o redimensionar una imagen o capa. A menudo, se usa para quitar bordes, o para eliminar areas no deseadas para proporcionar un area de trabajo más concentrada. También, es útil si necesitas un tamaño específico de imagen, distinto de las dimensiones del original.
Para usar esta herramienta, pulse sobre la imagen y arrastre la región rectángular antes de soltar el botón del ratón. Cuando se pulsa, aparece un diálogo mostrando las dimensiones de la región de recorte, y que permite relizar varias acciones. Si quiere alterar la región de recorte puede pulsar y arrastrar las esquinas o cambiando los valores en el diálogo. Cuando esté listo, puede completar la operación bien pulsando en el interior de la región de recorte o pulsando los botones recortar o redimensionar en el diálogo.
When the mouse becomes the moving cross-hair, you can use the keyboard arrow keys to move the crop rectangle. Holding the Shift key down allows to move by increments of 25 pixels.
You can use Guides to position the crop area. Make sure that the
→ option is checked.

You can activate this tool in different ways:
From the image menu bar
→ → ,
by clicking the tool icon:
in the ToolBox,
by using the keyboard shortcut Shift+C.
When you maintain click on the crop rectangle, handles disappear and
holding down the Ctrl key toggles to the Extend from Center option,
holding down the Shift key toggles to the Fixed option, which makes some dimensions fixed.
Normally, tool options are displayed in a window attached under the Toolbox as soon as you activate a tool. If they are not, you can access them from the image menu bar through
→ → which opens the option window of the selected tool.Esta opción hará, que recortar o redimensionar, afecte, solo, a la capa activa.
This option allows the crop or resize to take place outside the image (or layer), and even the canvas. So, you can give the size you want to the resulting image. Transparency will be used if there is no material to crop.

The option is checked. The crop rectangle extends outside the canvas.
The resulting image.
When this option is checked, the crop rectangle expands from the first pixel you clicked taken for center. You can toggle this option with Ctrl while drawing the crop rectangle.
Con esta opción, el recorte mantendrá la proporción entre la anchura y la altura.
Aspect ratio: That's the default possibility. Width and Height keep the same ratio they have in the original image, when drawing the crop rectangle.
Width / Height: Only Width or Height will remain fixed. The value of this dimension can be set in the text box below; it defaults to 100 pixels.
Size: Both Width and Height will be fixed. Their values can be set in the text box below, in the form “150x100” for example. The crop rectangle will adopt this values as soon as you click the image. On the right, two buttons let you choose a (widthwise) or (upright) format for the crop rectangle.
These two text boxes show the position (horizontal on the left, vertical on the right) of the upper left corner of the crop rectangle in real time and you can change it manually too. It is stated in pixels, but you can change the unit thanks to the drop-down list of the
button. The coordinate origin is the upper left corner of the canvas (not of the image).These two text boxes show the size (horizontal on the left, vertical on the right) of the crop-rectangle in real time and you can change it manually too.

All kinds of guides are described in Sección 2.2, “Herramienta de selección rectangular”
The Auto Shrink button will attempt to locate a border, in the active layer, from which to draw dimensions from. This option only works well with isolated objects contrasting sharply with background.

An image with a sharp limit in it and a crop rectangle.
After clicking the Autoshrink button, the crop rectangle has been shrunk to fit the sharp limits.
This option works the same, with Auto Shrink or not. It uses the pixel information from all visible layers, rather than just from the active layer.
