[Lcms-user] delta E questions

[Peter <in...@po...>]

Hello everybody,

I am try to do a deltaE for a inkjet proofing project but really do  
not know much about which function to use. I check the function  
headers and below are following choices,

double  cmsCIE94DeltaE(LPcmsCIELab Lab1, LPcmsCIELab Lab2);
double  cmsBFDdeltaE(LPcmsCIELab Lab1, LPcmsCIELab Lab2);
double  cmsCMCdeltaE(LPcmsCIELab Lab1, LPcmsCIELab Lab2);
double  cmsCIE2000DeltaE(LPcmsCIELab Lab1, LPcmsCIELab Lab2, double  
Kl, double Kc, double Kh);


Which one should I use ?

Thanks in advance.

Peter.
