Re: [Lcms-user] Embedded profile and ColorSpace tag

[Kai-Uwe B. <ku...@gm...>]

The steps to handle CM for images in a viewing applciation are outlined in 
a small use case study:
https://www.oyranos.org/wiki/index.php?title=Oyranos/Use_Cases
It is somewhat Oyranos centric as a place for interapplication settings.

In sumary:
* embedded profile - use it, if not
* EXIF - use it, if not
* ask a device profile data base, if no result
* ask user peferences for popping up a dialog and handle, if not popping
* ask user preferences, what to assign (for Rgb), if no result
* use sRGB for displaying, dont embedd for this case

kind regards
