3.8.2. Options

Afbeelding 17.25. Linear Motion Blur filter options

“Linear Motion Blur” filter options

Presets, Preview, Split view

These options are common to GEGL-based filters. Please refer to Paragraaf 2, “Algemene Eigenschappen”.

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.

Clipping

Het resultaat van dit filter kan groter zijn dan de oorspronkelijke afbeelding. Met de standaardoptie Adjust wordt de grootte van de laag automatisch aangepast wanneer het filter wordt toegepast. Met de optie Clip wordt het resultaat bijgesneden tot de laaggrens.

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.
