The Alien Map filter is a color mapping filter that works by applying mathematic algorithms to the existing color values in the active image. The mathematical color adjustments are made using a combination of Sine, Cosine, and None, in conjunction with sliders that vary the amplitude.
Alien Map Settings
The Red, Green, and Blue channel labels display and allow selection of the mathematical transform that will be used against that color channel.
Sine: The pixel color for that channel will be adjusted using Sine calculation.
Cosine: The pixel color for that channel will be modified using Cosine calculation.
None: No adjustment will be made to this color channel.
The three sliders represent the amount of color that will be used in the chosen calculations for each channel. The maximum value will use all available color information for that channel.
