Re: [Lcms-user] How to create an Icc profile

[<mar...@li...>]

Hi,

Color management, at least ICC color management, is a two step process.
You need both, ICC profiles for each device you want to integrate in the
workflow and a piece of software, called "CMM" that uses those profiles for
doing color management. 
ICC color management requires all "smarts" of gamut mapping to be placed in
the profiles. Then actually, building a profile involves a lot of *art*

LittleCMS is a CMM. It can use those profiles to perform color management.
It does NOT create profiles. It can be used to create the physical files
that contains the color mappings, but it does not compute the maps. I can
tell you that creating good profiles is a very difficult task, and takes
teams of color scientists to define algoriths and settings, taking into
account things like memory colors, skin tones, primary preservation and so.

So, littlecms is useless for you if you need to create profiles from the
end user point of view. As useless as it would be photoshop, which cannot
create profiles neither, it only uses yet-exiting profiles.

For the programmer point of view, lcms can be used to create the files that
contain the colormaps, and many people are using it in such way. That would
be, lcms is the canvas artists may use to do their creations. lcms would
take care of all details of the profile specification. If you use a library
to write PDF files, obviously would not ask that library to invent the
contents of your documents.

You have more information in the FAQ and in the documentation about the
role of lcms.

Hope that helps.
Marti

I wouldn't offend anyone, I ask the question in the wrong way, this is
the right way:
* Which advantages are there integrating data coming from ArgyII with
LittleCMS?
* Why LittleCMS can create icc profiles if it doesn't profile anything
(it's not sarcastic I would know what can I do with an hPROFILE
generated from scratch with lcms)?
thanks in advice.
