图 17.31. “Linear Motion Blur” filter options

Presets, “Input Type”, Clipping, Blending Options, Preview, Split view

	注意
	These options are described in 第 2 节 “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.

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.
