This filter creates a linear blur in a direction determined by the 「Angle」 option. The default direction is horizontal to the right (0.000 degree).

#### 3.7.2. オプション

図17.23 「Linear Motion Blur」 filter options

Presets, Preview, Split view

  These options are common to GEGL-based filters. Please refer to 「Common Features」.

長さ

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

角度

  「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.

Use selection as input

  Explained in 「モザイク処理」.

On-canvas controls

  This option (default) allows you to modify blur settings directly on canvas, for easier visual tweaking of blur settings. It displays a line with handle on both ends to vary direction and transform.
