I've just read a SVEN note (on gimp-dev) about Color Management Gimp support. Many things about DTP options (color separation, soft-proof, embed profile) which are very interesting but not many about CMYK native support (i.e. four channels).

The thread you read was about changes that we could do for GIMP 2.2. We are not going to add support for CMYK image data in the near future so that's why it wasn't mentioned.

If soft-proof is intended to be supported, it would be great to work on the color selector dialog.

The fact that at least monitor color correction needs to be applied to previews and color selections has been mentioned already.

LittleCMS is very good, but is written with Qt. I guess it will hardly be available on Windows.

Huh? lcms doesn't use Qt, what are you talking?

Actually, all this is not very clear : diplay filter there, channels there, and separate this way, who would it be 'packaged' ?

Does anyone has an opinion on all this ?

Well, if I would have understood your mail, I would probably have an opinion. But I am not sure if I've been able to follow you. I failed to understand what you are actually trying to tell us (except that you are confused).

Salut cedric,

Quoting cedric :

I've just read a SVEN note (on gimp-dev) about Color Management Gimp support. Many things about DTP options (color separation, soft-proof, embed profile) which are very interesting but not many about CMYK native support (i.e. four channels).

As Sven said himself, CMYK native support is not planned immediately. Since the GIMP Conference, we now have a pretty good idea of how and when it will be available, though.

LittleCMS is very good, but is written with Qt. I guess it will hardly be available on Windows.

LittleCMS does not require QT. It may have a QT-based front-end available, though. But there is a core library which "just" does colour correction, with no GUI elmements at all.

Actually, all this is not very clear : diplay filter there, channels there, and separate this way, who would it be 'packaged' ?

It seems like right now, there have been no formal proposals for something which will be done before 2.2 (no-one has yet said "I will do it, and here's how"). But there are a number of uncontested points. 1) Colour correction will be optional, if it is available at all. 2) Before any image data is changed by the application of a colour profile, the user will be prompted, informing him of a possibly destructive operation 3) Monitor profiles will be applied to the projection data, and thus will not change any image data.

The packaging would be as trivial as depending on littleCMS, and having a preference (or perhaps a number of preferences) for turning on/off colour correction.

So - back to the point I mentioned above - does anyone want to draw up a what and how of colour correction as they would implement it for 2.2?

Cheers, Dave.

Shouldn't we have that discussion on gimp-developer? Or at least include gimp-developer on it?

iirc, lcms was written on Windows.

At least there are Debian packages for it.

Yes, of course. My mistake. But then, aren't all the developers subscribed to gimp-user too? ;-)
