Thanks! Will this create profiles that deal with the hexadecimal rounding issue?
Yes,
Graeme.
Thanks very much! for the sample code.
I'm not familiar with jam, but after compiling everthing the first time,
this command compiles only mkDispProf.c:
argyll163_src $ jam -q -fJambase -j 3 -t icc/mkDispProf.c
The existing mkDispProf.c makes an sRGB profile with the sRGB TRC point
curve:
static double gdv2dv(double iv) {
double ov;
if (iv < 0.04045)
ov = iv/12.92;
else
ov = pow((iv + 0.055)/1.055, 2.4);
return ov;
}
It was easy to modify mkDispProf.c to make a profile with a different
set of primaries and different white point, plus a linear point curve.
How do you modify it to make a true gamma curve such as gamma=1.0,
gamma=1.8, or gamma=2.2?
I tried saving the modified mkDispProf.c under a new name "mkNewProf.c"
and compiling it:
argyll163_src $ jam -q -fJambase -j 3 -t icc/mkNewProf.c
but that doesn't work. Perhaps some other file needs to be modified to
tell jam what to compile?
