public int Factor { get; set; }
Represents the factor to be applied in the method operation specified in the specified in the Mode drop-down list box in the LUT Curve section of the Window Leveling dialog box. This parameter is used only if the Mode selected is RasterPaletteWindowLevelFlags.Exponential, RasterPaletteWindowLevelFlags.Logarithmic or RasterPaletteWindowLevelFlags.Sigmoid. If RasterPaletteWindowLevelFlags.Exponential or RasterPaletteWindowLevelFlags.Sigmoid is specified, its value can be any integer (+1000/-1000). If RasterPaletteWindowLevelFlags.Logarithmic is specified, its value should be >= 0. If factor = 0, the lookup table will be filled linearly.
