set_lut_style

set_lut_style ( : : WindowHandle, Hue, Saturation, Intensity : )

Changing the look-up-table (lut).

set_lut_style changes the look-up-table (lut) of the device displaying the valid 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.

Parameters

`WindowHandle` (input_control)	window `->` integer
Window identifier.

`Hue` (input_control)	real `->` real
Modification of color value.
Default value: 0.0
Typical range of values: `0.0 <= Hue <= 1.0`
Restriction: `(0.0 <= Hue) && (Hue <= 1.0)`

`Saturation` (input_control)	real `->` real
Modification of saturation.
Default value: 1.5
Typical range of values: `0.0 <= Saturation`
Restriction: `0.0 <= Saturation`

`Intensity` (input_control)	real `->` real
Modification of intensity.
Default value: 1.5
Typical range of values: `0.0 <= Intensity`
Restriction: `0.0 <= Intensity`

Example

read_image(Image,'affe') 
set_lut(WindowHandle,'color') 
repeat(:::) >
get_mbutton(WindowHandle,Row,Column,Button) 
eval(Row/300.0,Saturation) 
eval(Column/512.0,Hue) 
set_lut_style(WindowHandle,Hue,Saturation,1.0) 
until(Button = 1).

Result

set_lut_style returns 2 (H_MSG_TRUE) if the window is valid and the parameter is correct. Otherwise an exception handling is raised.
