Presets, Preview, Split view

These options are common to GEGL-based filters. Please refer to Section 2, « Options communes ».

Length

In this case, « Length » represents the blur intensity. More Length will result in more blurring.

Angle

« Angle » describes the direction of the movement. Thus, a setting of 90 will produce a vertical blur, and a setting of 0 will produce a horizontal blur.
