MODIFY/LUT [method] [colour] [prflag]
16
modify the currently active LUT
19
Modify the currently active colour lookup table (LUT).
22
MODIFY/LUT [method] [colour] [prflag]
24
method = BAND, for overlaying a one colour band on the LUT
26
= ROTATE, for rotating the offset of one or all colours of LUT
28
= GRAPH, for changing interactively slope and intercept of LUT
30
= SQEEZE, for squeezing/stretching of LUT and moving the offset
32
= HSI, for modifying in H(ue), S(aturation),I(ntensity) space;
36
colour = colour(s) we want to work with:
38
for BAND: RED, GREEN, BLUE, WHITE, DARK, YELLOW, PINK,
39
BROWN, ORANGE and VIOLET (default = RED)
41
for ROTATE: RED, GREEN, BLUE or ALL (default = ALL)
43
for GRAPH: RED, GREEN, BLUE or ALL (default = ALL)
45
for SQUEEZE not applicable - all colours are affected
47
for HSI: HUE, SATURATION or INTENSITY (default = HUE)
49
prflag = only used for method BAND:
51
Y(es) or N(o) for displaying the intensity interval corrsponding to
52
the chosen band, defaulted to No
55
MODIFY/ITT, TUTORIAL/LUT, DISPLAY/LUT, GET/LUT, LOAD/LUT
60
Use the or arrow keys to modify the LUT. Press the EXIT button on the
61
mouse (rightmost button) to terminate.
63
For the method BAND you can also enter the colour as three integers,
64
like r,g,b defining the RGB values or as 0xrrggbb in hex. notation.
66
If invalid method or colour is entered, the defaults are taken.
68
For method ROTATE you must start rotating towards the right.
70
To save your new, modified LUT use the command GET/LUT which will
71
create a copy of the current LUT in MID_WORK.
75
MODIFY/LUT ROTATE GREEN
76
Rotate only the green colour of current LUT.
78
MODIFY/LUT BAND 255,127,0
79
Put an orange band over LUT.
81
MODIFY/LUT band 0xff7f00
82
Same as above specifying the colour in hex. notation.
