[Gimp-developer] Mac native version of GIMP

2010-02-24 Thread Gerhard
Hi all,
Are there plans for porting GIMP to Mac OS X using Aqua and not X11?

I'm interested in learning how to code user interfaces and in helping the
free software community (since it has developed so many useful software
that
I use daily). I've used GIMP for Linux and Windows but not for Mac. I'm
switching to Mac when Leopard ships. If there's a porting project I will
help coding the interface of GIMP for Aqua (or start a new project if
there's none).



no one helps for mac?

Hello Sven,  

I agree with you, but wouldn't it be nice to have once on a day 
something similar to the file  automation dialog in Photoshop? 

There one can choose for example contact sheet or batch processing.  
In batch processing one can select an action  (i.e. gimp-script), a 
folder for loading  the files for processing and one for saving them, 
and in which  kind the naming  is to be managed, and so on.

I think, this could be something for later plans in the far future.

Kind regards

Hello Sven, 

it's fine to getting aware of the beginning of the cms development in 
the Gimp! We'll need this stuff :-)

 Color management on Windows would ideally be implemented using the
 color management capabilities of the operating system. Same on Mac OS
 X where ColorSync should be used. For now we will however concentrate
 on the LCMS based implementation and of course we will make sure that
 it works on all supported platforms.

Hello Sven, like you mentioned before in other cms related threads, it 
is an good idea to make it possible to choose the CMM the user prefer. 
And also I thing it would be the best choice to use for default the OS 
specific build-in CMM, as you said above.

 Users will be able to load color profiles from whatever location they
 wish. I don't think we need to provide a way to specify profile
 directories. GIMP will remember the last location you loaded profiles
 from and if you need to use multiple profile directories, it's easy
 to add bookmarks for them.

That's a very good point, and it comes with the behavior we should keep 
in touch with: A very flexible implementation of cms into the gimp. I 
like this idea. 

 This goes however way too much into details yet. We can figure out
 such usability concerns as soon as the basic framework has been put
 in place.

When do you expect the basic framework will be up for discussions 
regarding the usability?

 ICC profiles can be stored in TIFF files. The parasite is just the
 way that GIMP deals with this information. I don't know off the top
 of my head if JPEG allows to embed ICC profiles. Since I would rather
 get back to work on the color management implementation, I kindly ask
 you to look that up in the JPEG spec yourself.

Yes, JPEG (JFIF) allows to embed ICC profiles. Also it's possible to 
choose CMYK as colormodel. At least JPEG2000 support this, and 
Photoshop is able to save normal jpeg files with an icc profile and in 
CMYK. It support's also clipping paths.[1]

 http://developer.gimp.org/standards.html has some links that
 you might find useful. If you know of any URLs that should be added
 there, let me know.

It may would be useful to make a special section colormanagement, and 
point for example to color.org fogra.org eci.org 
http://www.swop.org/specifications.html etc. 

Kind regards

 If we don't convert the image at load time, all plug-ins that change

 Since this is not the case for the time being, it would probably be a
 bad idea to not convert the image. As soon as we go further down the
 road and have all plug-ins as GEGL ops, this will change. But for the
 time being, I don't see much choice but to convert everything to sRGB.
 Note that we are just talking about the first step here. Something
 that we can achieve in the next few months, without changing each and
 every piece of code in GIMP and it's plug-ins.

Hello Sven,

Sorry for breaking the thread, but I was not able to find this message as
mbox-archiv. 

I think that the suggestions made by Hal V. Engel and Jan-Peter Homann (a
well known color management consultant in Germany, afair also a member of
the eci.org maillist, a very good resource for cms knowledge)are very
important for a professional color management in the GIMP.

I'm not a Programmer, but isn't it possible to make a plug-in which load's
the icc information at a first step, to offer the user the ability to
decide in which way he wants to handle the file regarding it's color space?

After this step the file will be converted into the choosed colorspace[*]
and then loaded into the gimp, displayed in the working colorspace,
corrected by the monitor profile, with the possibility to choose a color
proof view with a selectable icc profile for the soft proof.

Please, correct me if I'm wrong.

[*]
a. no colormanagement 
b. working colorspace (imho don't offer the user the ability to preselect
the working color space in the preferences and instead convert all files
into sRGB is the worst we can do) 
c. apply an icc profile and then as a suboption 
c1. convert it into the working color space.

For Gimp-print we can handle the icc like Jan-Peter Homann suggested.

I agree, that this behavior would be very close to the behavior of adobe
photoshop regarding color-management, which got imho a very good
implementation of a colormanagement for professional needs.

There are good starting points by Alastair M.Robinson blackfive [ a t ]
fakenhamweb.co.uk. 

He made a good start of such a plugin with it's 'separate' plugin:
http://www.blackfiveservices.co.uk/separate.shtml
He send me a copy of an improved version for gimp 2.x . 

Please see this thread in gimp user:
http://article.gmane.org/gmane.comp.video.gimp.user/6008

He also works on a programm called photoprint:
http://www.blackfiveservices.co.uk/photoprint.shtml
based on guten print for gimp. (GIMP-Print/GutenPrint version 5 (beta 2))

for example photoprint..

quote
o Can apply ICC colour profiles, with selectable rendering intent.
 
o Can generate rough-cast ICC colour profiles, given RGB Primary
chromaticity coordinates (x,y), Gamma values and White Point.
 
o Can read and use an embedded colour profile (currently TIFF only).
/quote

He's working on CMYK support implemented with Argyll:

quote
Coming soon:
Support for CMYK images and profiles (useful in combination with Argyll),
and widgets for dealing with physical dimensions.
[...]
CMYK images are not yet properly supported, but I intend to support these in
future.
/quote

I think it's very important for the future of the gimp, to handle color
management in a proper and professional way, to get it on a professional
level also for pre-press image processing. 

Is there an existing roadmap for this issue?

 It would be possible to do the following:
 
 - load image's raw data, and ICC profile
 - During display, convert from source colorspace to display
   colorspace

If you apply a conversion to the file there will be a loss of color
information, so it's necessary, that we avoid unneeded conversions to the
original file.

For example, if you convert from adobeRGB into sRGB and viceversa several
times, you wouldn't receive the original color impression never more, it's
lost, and there for in poor quality (comparable with the jpeg lossy
compression, keep that in mind).

So, we have to convert only the displayed version of the data, not the
original data (Jan-Peter, Hal and others, please correct me if I'm wrong).  

This is important, to get a display color as closed to the original scene in
nature as possible, adjusted to the display hardware by the measured or
proofed monitor profile.

While rendering the data for the display this way, the data itselves stays
in working color space, or original color space (as choosen by the user
while opening the file). 

It should be saved with the working color space e.g. as device independant
suggested by ECI.org eciRGB.icc, which is comparable with widegammut and
adobeRGB, or the original color space (as choosen by the user while opening
the file), to avoid unneeded conversions while saving the data. 

eciRGB.icc offers a wider range of colors compared to sRGB, which got a very
limited color space, so it avoids clipping, when converting e.g. from
scanner profiles to the working color space.

The user should archive the data in the recommended device independent
colorspace (e.g. for Europe according to the suggestion of the ECI in
eciRGB color space [1]).

To Print the data it should be converted to the printer profile (This should
happen in the service bureau or the printer service, maybe the printer
offers you the printer-device profile to do the conversion by yourself. At
home you can measure your inkjet profile for example, and apply that.)

If you want to save your work for web you should do that by using the
conversion from (the wider) working color space to sRGB the default for
webpublishing.

 - During saving, save the originally loaded ICC profile back to
   file, if the format supports it, or convert to sRGB if it
   doesnt.

This all should be flexible and interactive (there could be an easy mode
coosen in the preferences to disable colormanagement at all), and it's
important to retain as much original color informations than possible.

 
 The problems with that approach are
 
 - Lots of elements in the GIMP are not colorspace aware - for
   example, you would have to modify the paint tools to detect
   whether there was an ICC profile associated with a display they
   were painting to, and color convert the (sRGB) data that they
   are painting. This is not possible currently, and Sven has
   expressed a desire that color management be kept out of the
   core in the past.

Okay, so I assume, that my (and Hal's and Jan-Peter's) suggestions have to
wait for the release after GEGL? For a new rendering-engine further to
GEGL? GIMP 3.0?

I want only remember the developers that there is already a state of the art
color-management used by the printing industry, which the GIMP-developers
can't ignore while implementing colormanagement and CMYK or
multichannel/DeviceN mode for the GIMP. Just avoid to go into the wrong
direction when going further with the implementation of colormanagement.   

 - Data which enters the image from other sources (copy  paste
   from another image, for example) may have been in a different
   colorspace, requiring convertion or some other funkiness to
   keep things coherent inside the image

Photoshop lets pop up a dialog where the user can decide the kind of
conversion he will do for the pasted/dragged image.
 
 After this step the file will be converted into the choosed colorspace[*]
 and then loaded into the gimp, displayed in the working colorspace,
 corrected by the monitor profile, with the possibility to choose a color
 proof view with a selectable icc profile for the soft proof.
 
 We currently have the ability to do color proofs with external
 ICC profiles. THe interface to the loading of the profiles isn't
 perfect yet, but it's there.

Desired is a 'On the fly' Softproof.

I admit, that this is a very complex subject, and it is much work to
implement all this color stuff into the GIMP, but I'm shure it's worth it.

Thank you

Gerhard

 You misunderstood me then. Managing colors does of course belong into

 The idea is to be able to use different color management systems and
 not to restrict ourselves to lcms. GEGL seems to offer just the right
 level of abstraction that would be needed here. That's why it seems
 like a nice idea to use it.

That's a good point, also because in the lcms-user maillist there was a

 Why? Almost everything you listed can already be done in GIMP.  It's
 just a bit akward to do it from a user interface point of view and
 that's what we want to improve for GIMP 2.4.

This is good to hear!
 
 Desired is a 'On the fly' Softproof.
 
 Could you explain what you mean by on the fly softproof and how that
 is any different to the softproof that's available?
 

What kind of softproof is available? Hmm.. I can nothing similar find here. 

I got under Image  Separate  Proof the possibility of an Softproof (plug
in 'separate' by Alistair M. Robinson). It shows up a dialog which asks me
the Source Profile /usr/lib/scribus/profiles/AdobeRGB1998.icc and the
Destination Profile
/usr/lib/scribus/profiles/USWebCoatedSWOP.icc (defaults, should be
eciRGB.icc and isocoated.icc according to eci.org [1]) and the checkboxes
Preserve Pure Black and Overprint Pure Black. If I press OK I got the
message-dialog PROOF IMAGE Image is not separated So I have to
separate the image first into cmyk mode by the plugin 'separate'. That's
not a Softproof 'on the fly'.

So I have to seperate the image first. I do it with the default profiles. A
new image with the CMYK separated RGB shows up (5 layers, 4 layers CMYK
mode 'darken only' 1 Background, Image in RGB Mode, if I save that it will
be saved as cmyk tif). The 3rd step is to proof that image with the CMYK
profile. A 3rd image pops up (RGB, 1 Layer)... That's Not a on the fly
preview at all.

Please, I'm sorry for my sad english, and I hope this all doesn't sounds to
rude. I wanted only spend some Information of an user point of view, that's

 the color-profile attached to an image.

I like the idea of an abstract API, which can be managed by different cmm
e.g. lcms or argyll 

This seems to be all over viewed a reasonable practice to use CMS on image
manipulation.

 agreed, but flexible enough to set it to saturation or absolute rendering
 intend.

 see above europe: isocoated.icc

see above, keep it flexible! You have to have the access to choose the
printer profile of the device, which is used actually !

[Gimp-developer] Can't unsubscribe?

2001-12-17 Thread Gerhard Siegesmund

Hello all

I now for some time tried to unsubscribe from this list. Unfortunately
the mechanism to do so is broken. I tried to unsubscribe as told in the
mails but got the attached response. Problem is, I don't anymore now my
password. So I asked for help and got the answer that I could get my
password from http://lists.xcf.berkeley.edu/list...(and.so.on). Problem
here is, I can't get a connection to that webserver. I always get a
connection-refused message. I tried it on two computers here in germany
(one in the university net and one where I work). So. How do I
unsubscribe? Sorry to bother you.
