[Openicc] cupsICC on remote CUPS servers Part 2

[Jan-Peter Homann]

Hello Hal and all,
So far as I understand, we have no possibility to pull the ICC profiles 
on a remote CUPS Server, but instead it is widely used, that a PPD is  
pulled from the remote CUPS server.

I´m not developer, but I´m working regularly together with developers. 
 From this experience, the manipulation of pure ASCII files like a PPD 
is not something very complicated.
Is it really a lot of work to create e.g. a basic PPD without color 
relevant entries and update the color relevant entries from profile 
Divtype metadata, which are installed on on the remote CUPS server ?

Lets assume, that the DictType Metadata in the ICC-profile contains the 
qualifiers for cupsICC, and the profiles are already installed in the 
correct folder for the cupsICC workflow.

What we would have to do would be mainly:

- Parse all ICC-profiles in CUPS profile directory
- read cupsICC qualifiers and profile filename from every profile
- create PPD entry for color relevant data
- merge color relevenat PPD data with standard PPD data
- let CUPS clients pull the updated PPD

Is this a way could solve the color problems, we have currently with the 
remote CUPS print path ?

Best regards
Jan-Peter
