These options are common to GEGL-based filters. Please refer to Section 2, “Common Features”.

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.
