lut
lut number(n)
Returns LUT number n (n = 0: red, 1: green, 2: blue): 256 values between 0 and 255.
lut(x1,x2,x3,...)number(n)
Fills the lut n with values x1,x2,...
Option:
ext(e,c,f): the curve is extended by ext(e,c,f).
Example:
lut[0,255]number(0)=;
initializes linearly the red lut.
lut number(n) acc
Fills LUT n with an accelerated curve (3 luts default).
Example:
lut(2) acc;
fills the blues LUT with an accelerated curve.
lut number(n) dec
Fills LUT n with a decelerated curve (3 luts default).
lut number(n)ini
linearly initializes LUT n.
lut brush(id)
lut brush(id)
Returns the 3D polygonal line.
lut brush(id)=x1,y1,0, x2,y2,0, ...
Changes this line.
Note:
the pixels color of brusb id will be modified
according to the law (x1,y1,0, x2,y2,0, ...).
lut image
Same as lut by adding image(id):
lut(x1,x2,x3,...)number(n)image(id);
lut acc image(id);
lut dec image(id);
lut law image(id);
lut pend image(id);
lut ini image(id)
