Hi,

Since Sven proposed discussing 2.4 in mailing list and none of my questions/proposals are reflected in the bugzilla, here they are. Before you read any further, please note that I'm not trying to look smarter than you, I'm just initiating discussion ;-) Please prove me wrong where I am wrong.

1. Is it planned to have separate+ as part of 2.4? There was some mentioning of it in gimp-developer@, but the thread came from some other mailing list or a private discussion, so no clues.

2. If it is planned to have separate+ as part of 2.4, we need a better place for its menu entries and a better integration into core (more below).

3. Is it planned to support OpenIcc's initiative to look for profiles in /usr/color/icc and ~/color/icc on Linux and standard profiles directories on other systems? If no, why?

4. If the answer to 3) is "yes", is it planned to implement reading device classes from ICC profiles and group profiles in comboboxes in "Color management" tab of Preferences dialog, showing names and not filenames, which would improve usability? If it is planned to have separate+ as part of 2.4 and make GIMP read device classes, then Separate/Proof/Save dialogs will have to be redesigned in a consistent manner as well (more below).

5. Main question: is color management going to be enabled by default in 2.4? With Scribus we found out that users actually demand it (on all platforms) and that it is safe, if sane defaults are used.

Now on separate+ plug-in.

If there are some requirements it doesn't meet to be part of 2.4, what are those?

Currently the functionality is spread across 5 dialogs:

1. Duotone. Traditionally people would expect this in /Image/Mode, but this duotone is not a real image mode, but an emulation. What would be the best place to your mind?

2. Proof. This should live in some obvious place in /Image/. Only context valid profiles should be suggested (see question 4 above).

3. Save. Ideally, this should be a "CMYK separated TIFF image" option in Save/Save As/Save As Copy dialogs. Only context valid profiles should be suggested (see question 4 above).

4. Separate (normal). I don't know, what's the best place in menu is. What do you think?

5. Separate (to Colour). Same as above.

I would also merge "normal" and "to Colour" into one dialog with a combobox or a radiobuttons group to switch between them and a hint explaining the difference.

It would be great hearing from you.

Cheers, Alexandre

I thought about having it in 2.4 but I think it's probably best distributed seperately until we find the time to integrate it properly. Since we are almost ready for 2.4, we should probably not add any new plug-ins at this point.

3. Is it planned to support OpenIcc's initiative to look for profiles in /usr/color/icc and ~/color/icc on Linux and standard profiles directories on other systems? If no, why?

Yes, we plan to support it at some point. But it's too late to implement this for 2.4. Fortunately though we are planning to release 2.6 shortly after and that should give us the chance to add a proper ICC profile selection widget that can be used from the core and from plug-ins.

5. Main question: is color management going to be enabled by default in 2.4? With Scribus we found out that users actually demand it (on all platforms) and that it is safe, if sane defaults are used.

Not sure yet. It depends on how well it works by then and if we manage to find sane defaults.

Hi,

The functions included in Separate+ are jointly used, so I think that it is appropriate that those are placed in the same submenu.

I don't understand where the "Separate" menu should be placed. However, I don't have the sense of incompatibility very much even if it is in a present place.

Only context valid profiles should be suggested (see question 4 above).

It isn't what I should do.
Appropriate widget will be added to the GIMP's core in the future. Then I will use it.

I would also merge "normal" and "to Colour" into one dialog with a combobox or a radiobuttons group to switch between them and a hint explaining the difference.

Try Separate+ (20070115).
I'm not good at English, and pardon the incompleteness of the explanation, please.

Makes sense.

Is it possible to at least default to /usr/share/color/icc or ~/.color/icc on unixes in current dialog?

You can reuse default settings in Scribus (those applicable ones) ;-)

The profile file selection dialog isn't finished yet. But it already installs a shortcut to the systemwide profile folder. At least on UNIX, no idea if there's a similar folder on Win32.

It is located at [WINDOWS]\system32\spool\drivers\color\ at least on 2000+

Perhaps this could be useful too:

Is there anyone who knows of a specific icc color profile registry key?
