CHAPTER 13. FILTERS 158
Orientation Defines which way the ripples occur. Either horizontal or vertical.
Edges When applying a ripple effect, the tool performs the distortion within the con-
fines of the selection so there will be small areas at one edge of the selection
which are missing.
Selecting Black fills in these area with solid black, Smear will fill this area with
pixels stretched to fill, and Wrap fills the blank area with the pixels that were lost
from the other side of the image.
Wave Type The wave type defines how the curve of the wave is calculated. Sawtooth
renders a sharper wave. Sine renders a softer wave.
Parameter Settings Setting the Period controls how long the waves are or the dis-
tance between two crests. Amplitude defines how high the wave is or the vertical
distance between the mean and a crest.
