The Gaussian Blur plug-in acts on each pixel of the active layer or selection, setting its Value to the average of all pixel Values present in a radius defined in the dialog. A higher Value will produce a higher amount of blur. The blur can be set to act in one direction more than the other by clicking the Chain Button so that it is broken, and altering the radius. GIMP supports two implementations of Gaussian Blur: FIR and RLE. They both produce the same results, but each one can be faster in some cases.

These options are common to GEGL-based filters. Please refer to Sección 2, “Características comunes”.

Tamaño X, Tamaño Y

Aquí puede establecer la intensidad del desenfoque. Alterando la relación de desenfoque desde el radio horizontal hacia el vertical, se puede conseguir el efecto de un desenfoque movido.

Auto: Try to select the right filter automatically.

FIR: stands for Finite Impulse Response. For photographic or scanned images.

RLE: stands for run-length encoding. RLE Gaussian Blur is best used on computer-generated images or those with large areas of constant intensity.

Política del abismo

Abyss policy (border management) is treated with Política del abismo.

Recortar en la medida de la entrada

Should the output extent be clipped to the input extent: this option removes unwanted pixels created on borders by blurring.
