How far the twirl extends from the twirl center. This value is a percentage of width or height of the layer,
Twirl Radius
whichever is greater. A value of 50, for example, produces a twirl that extends to the edges of the layer.
Warp effect
Use Warp to distort or deform layers. The warp styles work much like the Warp effects in Adobe Illustrator and Warp
Text in Adobe Photoshop.
This effect works with 8-bpc and 16-bpc color.
Warping a layer
Wave Warp effect
The Wave Warp effect produces the appearance of a wave traveling across an image. You can produce a variety of
different wave shapes, including square, circular, and sine waves. The Wave Warp effect is automatically animated at
a constant speed across the time range (without keyframes or expressions). To vary speeds, you need to set keyframes
or expressions.
This effect works with 8-bpc and 16-bpc color.
The shape of the wave.
Wave Type
The distance, in pixels, between wave peaks.
Wave Height
The size of the wave in pixels.
Wave Width
The direction the wave travels across the image. For example, a value of 225˚ makes the waves travel diago-
Direction
nally from upper right to lower left.
The speed (in cycles per second) at which the waves travel. A negative value reverses the wave direction,
Wave Speed
and a value of 0 produces no movement. To vary wave speed over time, set this control to 0, and then set keyframes
or expressions for the Phase property.
Which edges to pin so that the pixels along those edges aren't displaced.
Pinning
The point along the waveform at which a wave cycle begins. For example, 0˚ starts the wave at the midpoint
Phase
of its downward slope, and 90˚ starts it at the lowest point in the trough.
Sets the amount of anti-aliasing, or edge smoothing, to perform on the image. In many cases, lower
Antialiasing
settings produce satisfactory results; a high setting can significantly increase rendering time. Anti-aliasing is
performed only if the layer quality setting is Best.
