[Openicc] GoSoC 2011: CPD and Color Management

[Jan-Peter Homann]

Hello to all,

I have some questions to different people on the list

1) Kai-Uwe, Richard, Graeme,
Lets imagine the OpenICC community would develop a tool for adding an 
ICC dictType entry with Gutenprint driver setup to an existing ICC 
printer profile.
What would be a good development strategy, that both Oyranos, g-c-m or 
ArgyllCMS can make use of this tool


2) CUPS specialist out here
Do GhostScript, poppler and other xx_to_raster filter allow to embedd 
the target profile into the rasterfile sent to rastertogutenprint ?
If not, who is in charge to change this ?

3) Robert
How many days development would be needed, to extract the gutenprint 
settings from the dictType entry of an ICC-Profile ?

4) Robert and other
Do you think it is possible to make write a modular softwaretool for the 
extraction process of the dictType entry from the ICC-profile, that 
other developers of drivers could also implement this process.
(For shure, their internal driver settings will be complete different  
from the gutenprint Syntax...)

Does it make sense to deliver such functionality with Oyranos or 
g-c-m/colord ?


5) Joseph
Could you sponsor some of your GSoC time for the realization of the 
described workflow ?


Best regards
Jan-Peter
