◆ _cmsAdaptationMatrix()

cmsBool _cmsAdaptationMatrix ( cmsMAT3 *const  r,
const cmsMAT3 *  ConeMatrix,
const cmsCIEXYZ *const  FromIll,
const cmsCIEXYZ *const  ToIll 
)

Returns the final chromatic adaptation from illuminant FromIll to Illuminant ToIll The cone matrix can be specified in ConeMatrix. If NULL, Bradford is assumed

◆ _cmsBuildRGB2XYZtransferMatrix()

cmsBool _cmsBuildRGB2XYZtransferMatrix ( cmsMAT3 *const  r,
const cmsCIExyY *const  WhitePt,
const cmsCIExyYTRIPLE *const  Primrs 
)

Build a White point, primary chromas transfer matrix from RGB to CIE XYZ This is just an approximation, I am not handling all the non-linear aspects of the RGB to XYZ process, and assuming that the gamma correction has transitive property in the transformation chain.

the algorithm: 

       - First I build the absolute conversion matrix using
         primaries in XYZ. This matrix is next inverted
       - Then I evaluate the source white point across this matrix
         obtaining the coefficients of the transformation
       - Then, I apply these coefficients to the original matrix

References FALSE.
