/* General overview on how to be a CMS plugin:
|
||||
* |
||||
* First, some nomenclature: |
||||
* |
||||
* CMF: Color management framework, i.e. "Use foo.icc for device $bar" |
||||
* CMM: Color management module that converts pixel colors, which is |
||||
* usually lcms2 on any modern OS. |
||||
* CMS: Color management system that encompasses both a CMF and CMM. |
||||
* ICC: International Color Consortium, the people that define the |
||||
* binary encoding of a .icc file. |
||||
* VCGT: Video Card Gamma Tag. An Apple extension to the ICC specification |
||||
* that allows the calibration state to be stored in the ICC profile |
||||
* Output: Physical port with a display attached, e.g. LVDS1 |
||||
* |
||||
* As a CMF is probably something you don't want or need on an embeded install |
||||
* these functions will not be called if the icc_profile key is set for a |
||||
* specific [output] section in weston.ini |
||||
* |
||||
* Most desktop environments want the CMF to decide what profile to use in |
||||
* different situations, so that displays can be profiled and also so that |
||||
* the ICC profiles can be changed at runtime depending on the task or ambient |
||||
* environment. |
||||
* |
||||
* The CMF can be selected using the 'modules' key in the [core] section. |
