Creates a torus-shaped lens and distorts the portion of the image over which the lens is placed.
Effect Parameters
Presets
Presets contain a snapshot of the plug-in parameters. The Presets control lets you choose among one of the presets built into the plug-in, save current parameter values to a preset file, or load an existing preset file from disk.
A preset file saved to disk via the "Save As" button can be loaded from another instance of the same plug-in by clicking the "Open" button. Presets generated in one host can also be loaded from the same plug-in when used in a different host.
Center
The center of the lens.
Radius
The radius of the torus-shape.
Width
The width of the lens, relative to the circumference at the center of the torus-shape.
Refraction
The amount of refraction caused by the lens.
Repeat Edges
Controls whether pixels that are accessed outside the edges of the frame have the value of the closest edge rather than black. This option prevents transparent black pixels from bleeding into the picture when the effect is applied. This option may negatively affect rendering times on older hardware configurations.
