Afbeelding 17.86. “Waves” filter options

Presets, Preview, Split view

	Opmerking
	Deze opties staan beschreven in Paragraaf 2, “Algemene Eigenschappen”.

Center X, Center Y

Move the center of the waves

Amplitude

Varies the height of the waves.

Period

That is wavelength. Varies the distance between the top of waves.

The high default value suits large images. For images of some hundreds pixels wide and high, a lower value, such as 20 in our example, fits better.

Phase shift

This command shifts the top of the ripple.

Aspect ratio

Values less than 1.00 render waves oval, with major axis vertical. Values higher than 1.00 give a major axis horizontal.

Resampling method

These interpolation methods are described in Interpolatie.

Clamp deformation

TODO.

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.
