Color management modules

Overview

A Color Management Module (CMM) performs the calculations for a color conversion. ColorSync includes a default CMM and can load additional CMMs packaged as bundles. Most apps never work with a CMM directly, because ColorSync selects one automatically. You can also enumerate the installed CMMs, choose a preferred CMM for a transform with kColorSyncPreferredCMM, or implement your own by exporting the required entry-point functions from a bundle.
