Set fixing of "look-up-table" (lut)
Behaviour for Mode = 'true': ::set_fix fixes that pixel lastly ascertained by one of the operators ::set_gray, ::set_color, ::set_hsi or ::set_rgb (Remark: Here a pixel is the index within the current look-up-table). To assign a new color to a fixed pixel set a color or gray value by using ::set_color, ::set_rgb, ::set_hsi or ::set_gray. This makes it possible to define any color (::set_color), any gray value (::set_gray) and any color combination (::set_rgb, ::set_hsi) at any position of the look-up-table.
Mode set to 'false' reset the fixing. To modify or create a look-up-table process ::set_pixel, ::set_fix(WindowHandle,'true'), ::set_rgb and ::set_fix(WindowHandle,'false') one after another.
As a side effect ::set_fix can change colors of "non-HALCON windows".

WindowHandle (input_control) |
window -> HTuple.long |
| Window identifier. | |

Mode (input_control) |
string -> HTuple.char * |
| Mode of fixing. | |
| Default value: 'true' | |
| List of values: 'true', 'false' | |
::set_fix returns H_MSG_TRUE if the window is valid, the hardware supports a look-up-table and all parameters are correct. Otherwise an exception handling is raised.
