[Lcms-user] Lcms python - DeltaE calculous

[Gonzalez C. J. <jor...@hp...>]

I am using the little cms in python but when I want to use the cmsCIE94DeltaE(Lab1: 'cmsCIELab', Lab2: 'cmsCIELab') -> "cmsFloat64Number": function i get a argument 1 of type 'cmsCIELab const *'. What i do is the following:

Import littlecms as lcms

Color1 = lcms. cmsCIELab
#The vàlues are an example
Color1.L = 12.0
Color1.a = 14.0
Color1.b = 22.0

Color2 = lcms. cmsCIELab
#The vàlues are an example
Color2.L = 15.0
Color2.a = 14.0
Color2.b = 22.0

Distance = lcms.cmsCIE94DeltaE(Color1,Color2)
