Original

Blur applied

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. Options

그림 17.23. “Linear Motion Blur” filter options

Presets, Preview, Split view

  These options are common to GEGL-based filters. Please refer to 2절. “공통 특징”.

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.

Use selection as input

  Explained in 3.4절. “Pixelize”.

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.

  Press Ctrl key to change direction by 15° steps.
