Okay today i tried as you suggested:
more_magic()
{
int curve[65536];
...
output = tranform_rgb_as_usual(input);
orgluma = cumpute_luma(output); /* I tried input aswell */
dstluma = curve[orgluma];
a = dstluma / orgluma;
output.r *= a;
output.g *= a;
output.b *= a;
...
}
This didn't do the trick either.
