Pulls the vertices of a path outward while curving the segments inward (Pucker), or pulls the vertices inward while curving
the segments outward (Bloat).
Creates multiple copies of a shape, applying a specified transformation to each copy. (See Using the Repeater to replicate
shapes .)
Rounds corners of paths. Higher Radius values cause greater roundness.
Animate the Start, End, and Offset properties to trim a path to create results similar to results achieved with the Write-on effect
and the Write On setting for paint strokes. If the Trim Paths path operation is below multiple paths in a group, then you can choose to have
the paths trimmed simultaneously or treated as a compound path and trimmed individually.
Aharon Rabinowitz provides a video tutorial on the Creative COW website that shows how to use the Trim Paths operation to animate a
dashed line following a path on a map.
Rotates a path more sharply in the center than at the edges. Entering a positive value twists clockwise; entering a negative value
twists counterclockwise.
Randomizes (wiggles) a path by converting it into a series of jagged peaks and valleys of various sizes. The distortion is
auto-animated, meaning that it changes over time without the need to set any keyframes or add expressions.
Several properties for this path operation behave the same as properties of the same name for the Wiggly selector for text animation. (See
Wiggly selector properties.) The Correlation property specifies the amount of similarity between the movement of a vertex and that of its
neighbors; smaller values create more jagged results, as the position of a vertex depends less on the position of its neighbors. The
Correlation property is similar to Correlation for the Wiggly selector, except that the Wiggle Paths version specifies the correlation between
neighboring vertices instead of neighboring characters. Set the maximum length for segment paths using an absolute or relative size. Set
the density of jagged edges (Detail) and choose between soft edges (Smooth) or sharp edges (Corner).
Animate the Size property to fade the wiggling up or down. To smoothly accelerate or decelerate the wiggling, set Wiggles/Second to a
constant value of 0, and animate the Temporal Phase property.
Randomizes (wiggles) any combination of the position, anchor point, scale, and rotation transformations for a path.
Indicate the desired magnitude of the wiggle for each of these transformations by setting a value in the Transform property group that is
contained in the Wiggle Transform property group. The wiggled transformations are auto-animated, meaning that they change over time
without the need to set any keyframes or add expressions. The Wiggle Transform operation is especially useful following a Repeater
operation, because it allows you to randomize the transformations of each repeated shape separately. (See
Using the Repeater to replicate
shapes .)
Several properties for this path operation behave the same as properties of the same name for the Wiggly selector for text animation. (See
Wiggly selector properties.) The Correlation property specifies the amount of similarity between the wiggled transformations of a repeated
shape and its neighbor within a set of repeated shapes. Correlation is only relevant if a Repeater operation precedes the Wiggle Transform
operation. When Correlation is 100%, all repeated items are transformed in the same way; when Correlation is 0%, all repeated items are
transformed independently.
When randomizing repeated shapes keep the following in mind: If the Wiggle Transform path operation precedes (is above) the Repeater
path operation, then all of the repeated shapes will be wiggled (randomized) in the same way. If the Repeater path operation precedes (is
above) the Wiggle Transform path operation, then each of the repeated shapes will be wiggled (randomized) independently.
Chris Meyer provides a video tutorial on the ProVideo Coalition website that shows how to use the Wiggle Transform path operation. This
tutorial explains why you must use multiple instances of the Wiggle Transform path operation if you want to wiggle multiple properties
independently.
Andrew Devis shows how to use the Wiggle Transform path operation in a video on the Creative COW website .
Converts a path into a series of jagged peaks and valleys of uniform size. Set the length between peaks and valleys using an
absolute or relative size. Set the number of ridges per path segment, and choose between wavy edges (Smooth) or jagged edges (Corner).
