Bezier Warp (PB only)
This effect shapes an image using a closed Bezier curve along the boundary of a layer. The
curve consists of four segments. Each segment has four control points (two vertices and
two tangents). The vertices control the position of the segments, and the tangents control
the curvature of the segments. Drag them to reshape the curves that form the edge, thus
distorting the image.

curved edge
For example, use Bezier Warp to reshape one image to fit another, as in wrapping a label
around a jar. Or correct lens aberrations, such as the fish-eye effect (barrel distortion) that
can occur when using a wide-angle lens. You can also bend the image back to achieve an
undistorted look. Animate the effect and choose a high elasticity setting to create fluid
visual effects, such as a jiggling gelatin dessert or a fluttering flag.

Bulge (PB only)
This effect distorts an image around a specified point, making the image appear to bulge
toward or away from the viewer, depending on the options you select. You can position
and shape the bulge in the Composition window or the Effect Controls window. Use the
Pin All Edges option to prevent edges of the layer from bulging.
