Yes, we're talking about two different things :-)
I meant detachable tabs and different views like Opera's or Scribus' 
ones. Not JUST tabs.
I (and as far as I could understand the other people that mentioned 
Opera) was talking about the ability to show the tabbed windows as 
tileable windows in the workspace (QT and Windows have that kind of 
options for child windows).
That is important when you need to have side by side comparisions of 
different images (examples of this are grading and gama matching,  two 
views at different zoom ratios, etc.)

Is that possible with the current GTK widgets?

How is that different? We already have detachable tabs in the GIMP user
interface. So why are you asking if this is possible?

Making it possible to have several images in one image window using tabs
would be a nice improvement, IMO. It needs some thoughts on the details
but perhaps this can be done off-list to that we can concentrate on
getting the roadmap for 2.6 done?

Sure there's tab widget. The point I was uncertain about was whether a  
second click on a tab would push it back in the z-order. I know Gimp is  
sometimes held back by limitations of GTK+ over which it has no direct  
influence.

2007-10-29 Thread saulgoode
What Mitch is referring to is that tabs are raised when doing  
drag-n-drops. I wish to thank Mitch for his brilliant implementation  
of this at the last minute of the 2.4 release. This functionality is  
already extremely useful for d-n-d'ing colors, channels, and layers  
between tabs and would also be necessary if GIMP provided tabbed image  
interface.

-

Though this discussion of UI issues is academically interesting (and  
will eventually prove fruitful), if GEGL is to be integrated into GIMP  
then that needs to be the primary focus for the next version.  
Potential developers will not be interested in spending a month of  
Sundays learning and programming for a system which is soon to be  
deprecated, requiring that their efforts be duplicated in the future  
or obviated completely.

Attracting users with alternative UIs or the concerns of graphics  
professionals will not mean more developers. Having a stable  
structure to the representation and access of GIMP's internal image  
data is a necessary precursor to attracting developers.

If GEGL can be integrated in less time than GEGL + something else  
then, unless something else can be justified as being more  
efficiently implemented at the same time, something else needs to be  
considered ancillary to GEGL integration.

here's the mockup (I made it long ago):
http://www.geocities.com/preacher_mg/UI_gimp_menu.png

I think the easiest way is with a last-clicked policy.  The GIMP
would hint to the user which image was active by either shading
inactive images (eg, making their rulers darker) or highlighting
the active image (eg, making the menu button brigher).  Perhaps
both of these concepts could be added to the mockup; currently it
looks like there are 5 active windows.

 So then what happens if I'm using focus strictly follows mouse and I
 put the mouse over another window (giving it focus)?  What if I don't
 click in the window, but do type a key (select a tool, for example)?

Don't focus on the word 'click'.  This has nothing to do with pointer
focus.  It's simply that the menu applies to the last image you did
something with.  And when you read did something with, think
clicked on and not moved mouse over.  Changing a tool or tool
option does not change what image you're working on.  The GIMP already
does something similar with the layers dialog.

Many thanks, I misunderstood your previous comment.

this is good news in several ways.

1. I can get ffx to do this as well , it's the sort of feature that you  
rely on after a while and miss badly.

2. Presumably Gimp can do the same sort of trick using std GTK+ widgets.

3. The code should be available as an example to make implentation simple  
and quick.

[Gimp-developer] weekend 2.6 UI roadmap roundup...

2007-10-29 Thread peter sikking
hi all,

let me see what since friday has been said (UI-wise) concerning
the roadmap.

Martin wrote:

 I suspect making use of Cairo won't impose significant changes to
 the spec?

Well it does, because instead of the current 1-bit (invert) graphics
for displaying the UI on the canvas, we could lighten/darken with
a much higher 'bit depth'. Which means that the current workarounds
(e.g. showing no side handles except on mouse over) can be replaced.

Then Sven put these (UI related) projects on the map, but not
necessarily on the 2.6 roadmap:

* next generation size entries

* finishing of:
  * Heal Tool
  * Sample Points
  * Foreground Select Tool

* Floating Selections

* Alpha Channel

* Layer boundaries

The ideas for these are mostly in sync with the conclutions the
UI team reached during the expert evaluation. Here I want to
say that what gets put on the 2.6 roadmap will be specified
first because it has a higher priority.

And then Guillermo opened the the debate about user request number one:

http://www.mmiworks.net/eng/publications/2007/05/lgm-top-gimp-user- 
requests_25.html#thebigone

and everybody starts discussing _how_ this could be done...

guys, roadmapping is about what you will deal with in the next release 
(s),
absed on how hard it will be to implement.

Now I really want to solve this mayor issue, it will be a
multi-facetted solution, but the developers keep telling me
that it is not going to be easy to implement.

Even to do the bare minimum (Removed the extra menu bar, the
inspectors have been made real floating windows, a first stage
of usability bug fixing before) would, if I understood Mitch +
Yosh right, involve patching all mayor window managers out there.

I am all for it that we do this as soon as possible, but I can
also understand that it is too much for 2.6.

[Gimp-developer] Feature desperately missed...

2007-10-29 Thread Karl Günter Wünsch
Hello,
maybe now is the time to get around to finally getting all the filter settings 
saved when exiting the gimp? 
Every single time I edit pictures I am annoyed that filters like unsharp mask, 
selective gaussian blur, decor border or almost any other one of them is 
loosing the settings I made during the previous setting. A radius of 5 on 
unsharp mask for example is whoefully inadaequate.
Unfortunately I can't get my head around the program paradigmas of GTK+ to be 
helpful as a developer otherwise I might have tackled this myself (I program 
exclusively C++ now)... But speaking as a daily user: this is the single most 
annoying lack of a feature of the GIMP.

I know there are tabs wich are detachable already. I was talking about 
the way that Opera as well as QT apps can manage different views of the 
tabbed windows.
In Firefox you have tabbed windows or a new window (with the whole 
chrome and buttons). In QT apps and Opera you can do the same, but also 
you can display views of the tabbed windos (as cascade or tiles).
That results in a sort of window in window interface. That's what I 
asking if it is possible in GTK. Not just the tabs.
That's why Alexandre posted the link to CurlyAnkles too.

Re: [Gimp-developer] Cairo for 2.6

2007-10-29 Thread William Skaggs


To my understanding, switching to Cairo for the canvas (and switching
away from XOR drawing) will involve two things:

1) Porting GimpCanvas to Cairo instead of raw GDK.  That should be pretty
straightforward:  I think virtually all of the relevant code lives
in app/display/gimpcanvas.c.

2) Changing the implementation of gimp_draw_tool_pause() in 
app/tools/gimpdrawtool.c, so that instead of erasing the drawing
using the XOR trick, it redisplays the projection of the image.  I
believe that getting this to happen efficiently will require maintaining
a pixmap of the projection as it is currently displayed.  Given that
that needs to happen in any case, this might be a good time to take
on the problem of displaying an interpolated view of the projection 
instead of the current every-nth-pixel view.

It seems you have missed quite a bit of what has happened in GIMP
development recently. GIMP displays an interpolated view of the
projection. The nearest-neighbour algorithm is not any longer used.

GIMP also maintains a pixmap of the projection, or at least something
that is very close to what is being displayed. It remains to be seen if
we need to add another level of caching there to get reasonably fast
tool drawing. It might be necessary to keep a copy of the displayed area
with all display filters applied so that tool expose events can be
served from this.

[Gimp-developer] 2.4 and how to continue from here

2007-10-29 Thread Sven Neumann
Moin,

currently we are still fixing bugs in the 2.4.0 release but it seems
that we caught the major problems now and want to prepare a 2.4.1
release soon. When that is done, we will immidiately create a gimp-2-4
branch to continue bug-fixing there.

At that point trunk will be open for development. But since we are
aiming for a short development cycle, we need to absolutely keep the
tree in a good shape. I don't want to see any commits that haven't been
discussed and approved beforehand. This doesn't mean line-by-line code
review. But I would like you guys to present your plans here beforehand
and not learn about them from reading the commit logs.

So if are planning any particular features for 2.6, now is the time to
present them here so that they can be put on the roadmap. This includes
stuff that has been planned for quite a while, like for example
finishing the metadata framework/editor (Raphael!), but also the port to
GEGL (Mitch!).

I suggest that we keep brainstorming for the 2.6 roadmap for another
week and then collect the ideas. It would be nice if we could end with a
list of well-defined tasks. When that list is collected, I would like to
discuss which of these tasks should be put on the roadmap for 2.6.

I'd add the quality of downscaling as a high priority need. Currently 
it's possible to downscale images using 50% steps at a time (it was 
discussed before) but it would be better if one single scaling step 
produces the best quality possible (maybe automating the 50% steps, as 
it was discussed before).
IIRC Sven informed that this issue would be easier to address with GEGL, 
so I don't know if proposing this fix before GEGL is appropriate. Anyway 
I'd like to point that it's a need for people who work with graphics for 
the web.

  That strikes me as utterly useless, what's the problem with pressing
  the mouse button if it is not otherwise occupied (e.g. by doing DND).

It allows more casual inspection of tabs (move move move, not move
click move click), and works particularly well with vertically-stacked
tabs or tabs whose content is in a folded away NoteBook.
I regard it as useful for inspectors, such as the Cursor tab and
Histogram tab, that I do tend to check casually, and selectors, such
as brushes, patterns, and brush editor, that can be used casually.

Of the seven tabs I have docked to the toolbox, three (palette editor,
pattern selector, brush selector) would be useful to access in this
way.

Ideally, each could be a fold-out window (like tooltips), which would
be accessed by hovering or clicking on an icon, rather than blocking
other dockables that *should* remain visible (eg. Colors, Layers).

If tabs could behave in this way, trying to avoid covering the
dockbook they are expanded from, and automatically reset to the
previously selected tab when done, this would work rather neatly.

Re: [Gimp-developer] weekend 2.6 UI roadmap roundup...

2007-10-29 Thread David Gowers
Actually I got the impression that it had changed, and now
box-filtering was used, which does account for all input pixels.
OTOH, Lanczos currently produces poor results. Geert Jordaans (sp?)
was working on improving this.

 it's possible to downscale images using 50% steps at a time (it was

 produces the best quality possible (maybe automating the 50% steps, as
 it was discussed before).
 IIRC Sven informed that this issue would be easier to address with GEGL,
 so I don't know if proposing this fix before GEGL is appropriate. Anyway
 I'd like to point that it's a need for people who work with graphics for
 the web.

Re: [Gimp-developer] 2.4 and how to continue from here

2007-10-29 Thread Filipe Soares Dilly
First of all I'm a Digital illustrator and 3d artist. GIMP in the actual
state is great. My job can be done in 2.4 easily (thanks for the Jitter,
scalable brushes and better zoom!). And I know that GEGL will be in the
future of GIMP and the interface already have great proposals (and
designers). So I decide to not propose these kind of features...

Ok, thats my feature request:

GIMP have a ease and very flexible way to create animated brushes, with
features like Random and Angular (to create brushes that rotates as
you move in different angles). The thing is: If we have some of these
features in the Tools Options for brushes will be more fast and ease to use
the brushes that are not animated.

Some examples:

- The Random feature could be simple rotating (in its own axis) the
original brush in a random way. Just a simple check box for activate it,
maybe a intensity control how much is random.

- The Angular could also be activated using a Check Box. The angle of the
brush changing as you drawn in different directions, dynamically rotating
the brush. His frequency controlled by the Space option in the Brush
Dialog.

- Other features that are avaible only creating animated Brushes could be in
to. But these to are just great.


Other proposal for brushes are a option to control the Softness and
Sharpness of Brushes. Today you need to create another brush just to change
his softness (or hardness). Maybe a good alternative is to have in the
Tools Options a Slider if two ways to go:

If you move the slider to the Left the brush will be Sharpened... to the
Right will be Blurred. Here is a very ugly mockup:

Thats it and thanks for the hard work.
