Is there a way to query the parametric constants for a tone curve?

[DominikDeak]

We can query the tone curve type using the cmsGetToneCurveParametricType function. Is there an equivalent way to access the parametric constants for a cmsToneCurve struct? If not, how practical is implementing such a feature in the API?

Actually there is no function to do that, but I think it would be quite easy, something like:

cmsFloat64Number* cmsGetToneCurveParams(const cmsToneCurve* t)
{
_cmsAssert(t != NULL);

if (t -> nSegments != 1) return NULL;
return t ->Segments[0].Params;

}

I will add this to the development sources, thanks for the idea!
