7.8.3. Options

Figure 17.154. “Spread” filter options

Presets, Preview, Split view

	Note
	These options are described in Section 2, “Common Features”.

Horizontal, Vertical

You can set the distance that pixels will be moved along Horizontal and Vertical axis. The axis can be locked by clicking the Chain icon.

Random seed

Controls randomness of spreading. If the same random seed in the same situation is used, the filter produces exactly the same results. A different random seed produces different results. Random seed can be entered manually or generated randomly by pressing New Seed button.

Clipping

The result of this filter can be larger than the original image. With the default Adjust option, the layer will be automatically resized as necessary when the filter is applied. With the Clip option the result will be clipped to the layer boundary.
