In GIMP, each layer has its own size that can be changed independently of the size of the image. This command changes the dimensions of a layer, but it does not scale its contents.

	Nota
	By default, painting outside the borders of a layer is ignored. You can, however, enable the Expand Layers setting in the Paint Tool Options, which will automatically extend the size of the layer when painting near one of its borders up to the size of the canvas.

7.53.1. Activar el comando

You can access this command

From the main menu through Layer → Layer Boundary Size….
From the Layers Dialog, you can access it through the Layer Boundary Size… command of its context menu.

Figura 16.112. El diálogo “Tamaño de borde de capa”

Template

This drop-down list allows you to pick a size from one of the available image templates. For more information on templates see Create a New Image or the Templates Dialog.

When choosing a template that has a different print resolution (ppi) than your image, two new buttons will appear that ask you how to adjust this.

Scale template to … ppi will adjust the template to the ppi of the image; and Scale image to … ppi will adjust the image to the ppi of the template.

Tamaño de capa

Width, Height: Cuando se visualiza el diálogo, se muestran las dimensiones originales de la capa activa. Puede cambiarlas usando las dos cajas de texto. Si estas cajas están enlazadas con una cadena, la proporción de anchura y altura se mantiene. Si rompe la cadena, al pulsar sobre ella, puede seleccionar las dos dimensiones independientemente.
Unit of Measurement: La unidad de medida predeterminada es el píxel. Puede cambiarla mediante el menú desplegable. Por ejemplo, puede usar “%” del tamaño actual.

X Offset, Y Offset

Estas coordenadas son relativas a la capa, no a la imagen. Se usan para mover un marco que determina qué parte del contenido de la capa se seleccionará para la capa redimensionada. En el ejemplo, la capa y el contenido tienen las mismas dimensiones y, por supuesto, no hay marco que mover. si reduce la Anchura y la Altura, el marco de la capa redimensionada aparee en la vista previa.

A Preview of the layer inside the frame of the canvas

Besides the layer dimensions, a preview represents the layer with the frame of the resized layer. You can move this frame using the X and Y offsets and also dragging the cross-shaped cursor that appears when the mouse pointer moves over the layer area.

Center

The Center button allows you to place the frame at the center of the layer.

Rellenar con

This allows you to select how to fill the background of the layer when you increase its size. The same options are available here as in the Create New Image Dialog.

7.53.3. Redimensionar la capa

Increasing the size of a layer

You can't make the size of a layer larger than the image canvas.

If the layer is smaller than the image, you can enlarge the Width and/or Height. If you want to enlarge the layer to the size of the image, it is easier to use Layers to Image Size.

Reducing the size of a layer

If you want to remove unused parts of a layer, you can reduce the size.
