Ripple effects
With the Ripple filter, create the impression of ripples in an image, like the ripples made by dropping
a stone into smooth water. By varying the controls in the Ripple dialog box, produce a range of effects
in an image, from slight rippling to extreme distortion.
To apply the Ripple filter:
1. Select a paint object. To limit the effect to a particular area, select the area where you want to
apply the filter. If you don’t make a selection, the filter affects the entire image.
2. Choose Image | Filter | Other | Ripple or use the Filter menu in the Properties bar.
3. Adjust the settings in the Ripple dialog box, and then click OK to apply the settings and close
the dialog box.
Ripple settings
Adjust the following settings in the Ripple dialog box.
Spin The Spin value controls the effect of swirling the image around its center
point. Type a number from -100 to 100 or drag the slider to set the
amount and direction of spin. Positive numbers generate a clockwise
spin; negative numbers generate a counter-clockwise spin. Larger
values (positive or negative) increase the amount of swirling. If Spin is
zero, the filter creates no ripples in the image and none of the other
controls produces an effect.
Frequency The Frequency value affects the number of “waves” created in the
image. Enter a number from 0 to 50. A high number creates more small
waves; a low number creates fewer large waves.
Clustering The Clustering option can create interesting interference patterns in
combination with some Frequency values. In general, Frequency values
of 15 to 50 and Spin values of 25 and higher are most effective. Enter a
Clustering value of 0 to 30. The higher the Clustering value, the more
interference ripples appear between the main waves.
Wave Decay The Wave Decay value softens the effect of the Frequency setting by
dampening or stretching the waves away from the center of the image.
The closer a wave is to the center of the image, the less it is stretched.
