Presets, 「Input Type」, Clipping, Blending Options, プレビュー, Merge filter, Split view

  | 注記
  These options are described in 「Common Features」.

Center X, Center Y

  Move the center of the waves

振幅

  Varies the height of the waves.

波長

  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.

位相変位

  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 補間アルゴリズム.

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.
