#### 5.15.1. Wirkungsweise

Abbildung 17.92. Anwendungsbeispiel für das Filter »Wellen«

Originalbild

Filter „Waves“ applied with default options and period = 20.0

Mit diesem Filter können Sie einen Effekt erzeugen, welcher Ihr Bild wie eine Wasseroberfläche formt, in die ein Stein geworfen wurde. Es werden kreisförmige Wellen aufgetragen.

#### 5.15.2. Activating the Filter

This filter is found in the main menu under Filters → Distorts → Waves….

  | Anmerkung
  These options are described in Abschnitt 2, „Gemeinsame Funktionsmerkmale“.

Center X, Center Y

  Move the center of the waves

Amplitude

  Varies the height of the waves.

Periode

  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.

Phasenverschiebung

  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 Interpolation.

Clamp deformation

  This limits the deformation in the image area. When this is disabled you seem to get transparent or black areas (depending on whether the layer has an alpha channel or not). When enabled, these areas will keep their normal color.
