A color correction filter which lets you swap the red, green and blue channels, as well as their inverse. Channel Swap also lets you pick the luminance (and inverse luminance) values during this operation.
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.
Red/Green/Blue/Alpha Source
These popup menu parameters let you assign a new value to each channel. You may pick the source to be RGB channels, the luminance information in the original image, as well as the inverse.
Mask
By default, the effect is applied to the entire image. The Mask parameter group gives you options for applying the effect only to specific parts of the image.
Mask Popup Menu
This popup menu lets you choose mask shape. The default setting is "None", which means that the effect is applied to the entire image. The available options include the most common shapes used for masking out effects. You may also supply your own mask shape by choosing the "Use Custom Mask" option in this parameter and dropping your own media into the "Custom Mask" image well parameter.
 Oval |  Rectangular |  Gradient |
 Bar |  Ring |  Custom Mask |
Custom Mask
This image well lets you supply your own mask shape when the "Use Custom Mask" option is set in the Mask popup menu parameter. Mask shapes should be grayscale images.
Mask Center
The position of the mask shape on the frame.
Mask Scale
The scaling factory of the mask.
Mask Aspect Ratio
The aspect ratio of the mask shape. The default value of 1 will generate a circle when the current shape is "Oval", and a square if the current shape is "Rectangular". An aspect ratio of 1 will also ensure that any custom mask image you supply via the image well is maintained at its native aspect ratio.
Mask Angle
The angle of rotation of the mask.
Mask Softness
Controls the smoothness of the transition between the in and out areas of the mask shape (indicated by white and black, respectively). When using a custom mask shape, this parameter controls a gaussian blur applied to the image to soften its color values.
Mask Invert
Controls whether the shape defined by the current settings is inverted. For example, an "Oval" mask will apply the effect inside the oval shape. By enabling this option, the effect will be applied outside the oval, hence simulating a common vignette.
Mask Preview
When this parameter is enabled, the effect renders a preview of the mask shape. This mode is helpful in setting up a precise mask shape when finalizing the effect setup.
