createLookUp()

lookup_t& createLookUp ( const std::type_info &  type, const ValueScaling &  scaling  ) const

inline

Creates a vector of 256 or 65535 entries for fast retrieval.

A codebook is assumed to be a sparse list, only containing entries where the values (colors) change. The corresponding lookup table contains an entry for each encountered integer index.

TODO: count parameter (now automatic) TODO: interval fill up function (mixer)

Main loop: traverses entries, and fills up lookUp indices between entries.

Fill up interval [indexLower, index[
