I like it when things get complicated...
I want to call the function cmsCreateLab2Profile.
But this function takes a pointer to cmsCIExyY parameter.
cmsXYZ is a struct -- I'm in love :(
So, in my call to the function, I need to pass a pointer to a cmsCIExyY
struct, containing the xy chromaticities of, say, D50 (0.9642, 1, 0.8245),
something like that (I'm going from memory).
So, first, in my C# program, I have to declare and initialize the cmsCIExyY
struct, in order to pass its address to the cmsCreateLab2Profile. Right?
This is how cmsCIExyY is defined in lcms2.h :
typedef struct {
cmsFloat64Number x;
cmsFloat64Number y;
cmsFloat64Number Y;
} cmsCIExyY;
BUT, it gets better! Turns out there is a cmsD50_xyY function that returns a
pointer to a cmsCIExyY struct with, presumably, the D50 xyY :
const cmsCIExyY* CMSEXPORT cmsD50_xyY(void)
{
static cmsCIExyY D50xyY;
cmsXYZ2xyY(&D50xyY, cmsD50_XYZ());
return &D50xyY;
}
The thing is, I scanned the whole lcms2.h and associated files but there are
no traces of a D50 definition?
I'm lost :(
