Parameters

frequency: Value that represents the frequency factor. This parameter is used if the FunctionalLightCommandFlags.Trigonometry or FunctionalLightCommandFlags.Freehand flag is set. Valid values range from 1 - 10000. This value is divided internally by 100 (corresponding to a real interval of 0.01 - 100.0).
redAmplitude: If the image is grayscale, this parameter represents the amplitude of the master channel. If the image is color and FunctionalLightCommandFlags.Multiply or FunctionalLightCommandFlags.LinearQuadratic flags are set, this parameter represents the amplitude of each channel. If the image is color and the FunctionalLightCommandFlags.Addition flag is set, this represents the amplitude of the red channel. This value is an integer with a value greater than or equal to 0. This value will be multiplied with the results of the selected function (sine, cosine, user buffer , _). The results of the multiplications are then added to the pixel values. These functions as well as the real buffer values are from -1 to 1. Possible values for this parameter are from 0-100.
greenAmplitude: Value that represents the amplitude of the green color when the addition operation is used (FunctionalLightCommandFlags.Addition flag is set). This value is ignored when grayscale images are used or when the multiplication operation is used (FunctionalLightCommandFlags.Multiply flag is set). This value is also ignored if the FunctionalLightCommandFlags.LinearQuadratic flag is set. Possible values for this parameter are from 0 - 100.
blueAmplitude: Value that represents the amplitude of the blue color when the addition operation is used (FunctionalLightCommandFlags.Addition flag is set). This value is ignored when grayscale images are used or when the multiplication operation is used ( FunctionalLightCommandFlags.Multiply flag is set). This value is also ignored if the FunctionalLightCommandFlags.LinearQuadratic flag is set. Possible values for this parameter are from 0 -100.
angle: Value that represents the angle, in hundredths of degrees. This parameter is used if the FunctionalLightCommandFlags.Trigonometry or FunctionalLightCommandFlags.Freehand flag is set. Valid values for this parameter range from -18000 to 18000. This value is divided internally by 100.
buffer: Array that holds all points that represents the shape drawn by the user. This parameter is used only if the FunctionalLightCommandFlags.Freehand flag is set. These values should be between -1000 and 1000. They are internally divided by 1000, so the real values are between -1 and 1.
flags: Flags that indicate the function applied to the image. For a list of the available flags, refer to FunctionalLightCommandFlags.
