- Option dockable is named "Align and Distribute" rather than "Alignment".
First, because it's not just about alignment; also because this way, it looks
like other software, such as Inkscape; lastly because it's more consistent
with other tool options ("Move", "Rotate", etc.).
- Add a tooltip to the Anchor Point widget to explain what it's used for.
- Rewrite various align/distribute button tooltips to make clearer that we are
aligning anchor points with specific edges (or distributing these anchor
points).
- Rename the first section to simpler "Targets".
- Some more rewording of other texts.
It's clearly broken right now. I can see it might have been used even to
progressively shift aligned items, but this was not used anymore. As for being
used while distributing, it doesn't make any sense anymore with the new logic of
not moving the extreme (first/last in coordinates) items.
I can see how an additional concept of offset can be useful in some situations,
but for now, let's get rid of this. We'll see in the future if someone asks for
it and provides valid use cases to work from.
There was one case in Inkscape which we could not do: distributing objects
keeping even gaps between them. Until now, we could only distribute keeping even
distance between anchor points (top, left, bottom, right or center).
With these 2 additional distribute options, I believe that GIMP is able to do
all the Alignment and Distribution options available in Inkscape (not the
"Rearrange" or node features, neither the text align/distrib; I just mean the
common align/distribute on objects), and even a bit more thanks to the anchor
point system (e.g. in Inkscape, we can't left or right-align to a reference
object/image center, or we can't center to a reference left/right/bottom/top
border; but we can do it in GIMP).
The icons are hopefully temporary, until we can make better ones.
After discussing with Aryeom, we decided that "Distribute" should work within
the current horizontal or vertical bounds, as this is how it is usually done in
other software (e.g. Inkscape). For instance, if there are 4 items, the first
and last (coordinate-wise) stay untouched, and only the 2 intermediate items get
distributed evenly.
Since the Reference is not relevant anymore for "Distribute", I undo part of my
previous commit, where I was organizing the reference setting into its own
section of the Alignment tool options. This setting is back as part of the
"Align" section.
- Adding a separate pivot widget to allow choosing which point of the items we
align or distribute. E.g. until now, we could only align the right side of
objects to the right side of the reference object, left to left and center to
center. Now these are independent. Therefore I can align the left side of
objects to the right border of a selection or a layer, and so on.
- Only keep 2 "distribute" buttons (for now). Most of the distribution actions
were basically broken or extremely hard to understand. Also they were
apparently mixing concepts of alignments with distributions. Now let's
basically only keep the bases: horizontal or vertical distributions.
Everything is still possible using a mix of alignment and distribution
buttons, and it's much clearer.
- Since the GimpAlignmentType was used nearly only there (except for some usage
like to store dock side or filter preview split direction, but these
GIMP_ARRANGE_* values were unused there), I removed the various enum values
which we don't use anymore.
- The Reference settings gets its own subsection in the Align tool options.
Until now, it looked like it only applied to alignment, whereas it applies to
distribution too.
Note: this is still work-in-progress, mostly some initial dev work to put some
algorithmic bases. We had some UI and specification discussions with Aryeom
already and some things might still change a lot.
When the reference is a guide in particular, no distribution is possible (on one
dimension, the size is 0, on the other, it's infinite) and alignment is only
possible in one direction (depending on guide orientation).
Instead of using the layer borders, we use the bounding box for the contents.
This is similar to first run "Crop to Content" on every selected layer except
we don't actually need to crop. Therefore we can work on bigger layer than the
actual content while still arranging them based on content bounds.
So often the result of alignment/distribution feels wrong because it doesn't
correspond to the content we are seeing. With this option, we'll have the option
to choose the desired behavior.
The old interaction was quite horrible. I don't think I ever really got a good
use of it. It was so hard to understand what you were picking and so on.
Now that we can multi-select items, let's just use this as the base of what we
want to align or distribute. Clicking on canvas will now mostly be used to pick
an item as reference. From now on, only the reference object will get on-canvas
handle, making it very obvious how your alignment or distribution will work.
I leave only an alternative picking method (with Alt or Shift-Alt pick) to add
guides to objects to align or distributes, as these don't have a selection
dockable.
I'm also improving the selection of stacked layers by looping through them
(similar as the layer selection on canvas feature) so that we can select even
background layers which have a lot of layers showing above.
I am planning to improve this tool even further, but this is a first step to
make it actually usable within the new multi-item interaction logic.
* Don't generate our own marshallers if they are available in GLib
already
* Don't set the c_marshaller parameter in `g_signal_new()` if it's a
default marshaller provided by GLib. See commit message of commit
39e4aa3c57 on why this is the case.
and remove a gazillion gtk_widget_show() all over the place, some
places need a gtk_widget_hide() now, and I'm pretty sure I broke at
least one thing in all those files...
Try to sort all GIMP_ICON_* defines into FDO categories like in
https://specifications.freedesktop.org/icon-naming-spec/latest/ar01s04.html
Add defines for all icons we override, rename some icons to their FDO
standard names, and mark the ones we duplicate with a comment so we
don't forget to rename those to standard names in 3.0.
Remove all stock items added since 2.8, restore accidentially removed
ones, and rename the newly added GIMP_STOCK_* defines to GIMP_ICON_*.
(will move to having GIMP_ICON_* defines instead of magic hardcoded
strings for all icons).
and remove lots of labels from calls to gimp_prop_foo_new(). Also
had to manually remove some unwanted labels that are now added
automatically, fixes bug #761880.
instead of passing N_()-strings; and remove gettext() calls on these
strings when using them. Reduces complexitx, and fixes double- and
untranslated strings. Also enables to treat properties of GIMP and
GEGL objects the same way, which was totally broken before.
The Align Tool had to be used in a very hacky way if one
intended to evenly distribute items across an image,
or other reference object (it would actually require one to
calculate the item spacing out of GIMP). This adds vertical
and horizontal fill modes: the reference object is divided
in N equal segments, where N is the number of items,
and each item is placed in the center of one of
these segments. The existing "offset" parameter
is used as an extra margin for the distribution,
and can be set to negative values, so that the items can
even get moved outside the boundaries of the reference object.
Added previously missing tooltips for options of the following tools:
Scissors Select tool, Foreground Select tool, Color Picker tool,
Zoom tool, Measurement tool, Align tool, Crop tool.
Changed a bunch of _() to N_() in Foreground Select tool's options
as per agreement with mitch.

2006-01-18 Michael Natterer <mitch@gimp.org>
* app/config/config-types.c: define GIMP_PARAM_STATIC_STRINGS
which is G_PARAM_STATIC_NAME|NICK|BLURB. Also define
