The width and height of the distorted area, in pixels. You can also set the radius values by dragging the
selection handles in the layer.
The apparent depth of the bulge. Positive values push the bulge toward the viewer. Negative values pull the bulge away from the
viewer.
The shallowness of the sides of the bulge. A taper radius of 0 produces a steep, pronounced bulge.
The amount of edge smoothing (blending of colors) at the boundaries of the bulge. Anti-aliasing is applied only when the layer
quality is set to Best.
Prevents the edges of the layer from bulging.
Corner Pin effect
The Corner Pin effect distorts an image by repositioning each of its four corners. Use it to stretch, shrink, skew, or twist an image or to simulate
perspective or movement that pivots from the edge of a layer, such as a door opening. You can also use it to attach a layer to a moving
rectangular region tracked by the motion tracker. You can move the corner pins in the Composition panel, the Timeline panel, or the Effect
Controls panel.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.

The AE Enhancers forum describes and links to an animation preset from Donat van Bellinghen for scaling a set of Corner Pin effect points.
The CC Power Pin effect—one of the Cycore FX plug-ins included with After Effects—provides some additional features. For information, see the
Cycore website .
