stira::imagedata::ProfileData Class Reference

class to manage data in a color profile Basically consists of a color LookUp Table (CLUT) between a device space (A) and an independant space (B) This independant space is usually L*a*b*. In a profile, we usually have two tables: in A2B, the values in the A space are on a regular grid and the corresponding B values usually aren't; in the B2A, the values in the B space are on a regular grid and the corresponding A values usually aren't More...
