The applet currently supports two methods of image generation. Trapezoid -- this method generates a standard color wheel -- a line with a hue parameter change from 0 to 255. In other words this is a real rainbow line. This method has no additional generation parameters. Gaussian -- this method generates a gaussian peak for each component based on other parameters supplyed. This method allows to generate some interesting effects. The parameters are: Mean value of each component . The parameters' names are: 'ar', 'ag', 'ab' for read , green and blue components correspondently. The obvious meaning of this value is -- it shows where the maximum intensity point is. This parameter is of 'double' type and may have a value on the range between 0 and 1. (The whole length of the bar is considered to be 1 i.e. the value of 0.5 means -- in the middle of the bar). Dispersion of each component -- it sets the width of gaussian peak or better to say the width, where intensity of the particular component reduces to it's one-half. The parameters' names are: 'sr', 'sg', 'sb'. There are also animation parameters supported. They are: 'delay', (Integer) -- delay of animation in milliseconds. Default value: 100; 'shift', (Integer) -- shift between two frames of animation. Default Value: 2; 'direction', (String) -- direction of animation. Possible values: ["left" | "right"], Default value: "left"; Author: Oleg V. Baranovsky --------------------------------------------------------------------------------
