Rotates pixels around a point to simulate a vortex. You can specify the number of rotations as well the center and radius of the effect.
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 vortex.
Radius
The radius of the vortex.
Angle
The angle that determines the number of rotations around the vortex center.
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.
