Changing the look-up-table (lut).
set_lut_style changes the look-up-table (lut) of the device displaying the active output window. It has got three parameters: Hue: Rotation of color space, Hue = 1.9 conforms to a one-time rotation of the color space. No changement: Hue = 0.0 Complement colors: Hue = 0.5 Saturation Changement of saturation, No changement: Saturation = 1.0 Gray value image: Saturation = 0.0 Intensity Changement of intensity, No changement: Intensity = 1.0 Black image: Intensity = 0.0 Changement affects only the part of an look-up-table that is used for diplaying images. The parameter of modification remain until the next call of set_lut_style. Calling set_lut has got no effect on these parameters.

set_lut_style returns TRUE if a window is activated and the parameter is correct. Otherwise an exception is raised.
