[Lcms-user] How to convert between TYPE_Lab_8 and cmsCIELab?

[Alan J. <ala...@ya...>]

Hi,



suppose I have color vectors with TYPE_Lab_8 (byte values) generated by cmsCreateTransform(). What is the canonical way to convert these byte values to the type cmsCIELab consisting of three cmsFloat64Number?

I need the conversion from byte to float values in order to call the function cmsDeltaE(const cmsCIELab* Lab1, const cmsCIELab* Lab2) for pairs of Lab pixels.


Thank you for your help!

Regards,
Alan
