39 interpolation tables are limited to 8 bits, I use Lab as a way to
41 of each CRD, CSA the profiles are converted to Lab via a device
42 link between profile -> Lab or Lab -> profile. The PS code necessary to
43 convert Lab <-> XYZ is also included.
103 Lab is used in such cases.
122 These are always implemented as CLUT, and always are using Lab. Since CRD are expected to
138 /RangeABC <.. used for XYZ -> Lab>
147 The following stages are used to convert from XYZ to Lab
171 EncodeABC finally gives Lab values.
179 The following stages are used to convert Lab to XYZ
