gimp_channel_is_empty returns FALSE if channel is NULL. This causes
gimp_layer_invalidate_boundary to crash if the mask channel is NULL.
With a NULL channel gimp_channel_is_empty should return TRUE, just like
the similar gimp_image_is_empty does, because returning FALSE here
suggests we have a non empty channel.
With large image sizes a 32-bit int is not enough for the intermediate
computations, which byte per pixel, width and height are.
So, just like the function below it does: gimp_gegl_pyramid_get_memsize,
we will cast these to gint64.
Thanks to Massimo Valentini for finding the cause.
Even if the container is empty, then we return a GStrv of length 1 (i.e.
an array of length 1, terminating with NULL).
In particular, it improves gimp_container_get_filtered_name_array() as
well, and in turn various list-returning functions in libgimp. This
makes the API more consistent after changes from commit 8eb7f6df9e.
Note that a NULL return can be acceptable for error cases, but an empty
list because this is the expected result for the request should be an
empty GStrv, not NULL.
Since GStrv are NULL-terminated arrays, there is always one additional
pointer (NULL).
This is a detail, but still, wrong since commit 8eb7f6df9e which
replaced GimpStringArray by GStrv usage.

In particular, we should not hardcode this in core code anymore. The
behavior is otherwise exactly the same, except that we made the core
code generic as it should be.
The CLI options now know which procedures are batch procedures or not.
First it means that it won't just randomly try any procedure name one
may pass and will properly output an error if you pass a non-existing
interpreter procedure.
Secondly, there is no default interpreter anymore (unless only one
interpreter exists). If you don't set an interpreter procedure with
--batch-interpreter or if you pass a wrong one, it will output the list
of available batch procedure, thus helping you understanding how to use
the --batch option.
If you call GIMP with batch commands and ask it to quit immediately, you
are likely interested by failure information. For this reason, let's now
report exit code other than success, but only in such case. In
particular, even if the batch commands fail, but GIMP is not set to exit
immediately, we continue reporting SUCCESS run at the very end (when
exiting interactively).
Note that I hardcode a few exit values, as standardly found on Linux
(but not using headers which may not be found on all platforms; in
particular, Windows apparently doesn't use any standard code other than
0 for success, from what my searches return).
Additionally, when several commands are requested, GIMP will now stop at
the first failing and will return its error code, and print a message on
stderr to easily report the failed command for easier debugging.
Since commit 4cf38d784f, when loading an indexed image, we would first
initialize a palette with 0 colors, then set it to the right colors.
Babl outputs the following message when initializing to 0 colors:
> ../../src/babl/babl/babl-internal.h:214 babl_log()
> attempt to create a palette with 0 colors. using default palette instead.
Let's only set the palette to Babl when it has colors.
… whether the program is really ready to accept various commands.
In particular, on macOS, one could drop an image to the app icon in the
dock while starting up (visible splash). Then if the profile convert
dialog appears *behind* the splash, it would block loading until an
action is taken (unfortunately as it's hidden, people may miss it and
would think GIMP froze), as reported by cyril and reproduced by lukaso.
I can't test myself, but I'm hoping this will fix the issue (similar to
commit a86ed68870 where we had a similar issue with dbus file opening
on Linux).
What it means is that we will be a bit strict over our <release>
formatting which will have to always be a <p> introduction followed by a
list of items. This is what gimp_appstream_to_pango_markups() expects.
Since so far, this is how all our <release> tags were formatted anyway,
this is not too much of a problem.
Note that I keep the less strict gimp_appstream_to_pango_markup() and
use it for extension's appstream description as we will have no control
over these.
The main reason for this new rule and new display of our release notes
is that I am going to add the ability to click independent release items
so that people can get "blinking" indications of what changed when
relevant.
This is the same thing as setting the max gap length to 0, except that
it would mean constantly having to play with the gap length and possibly
losing settings you carefully tweaked. Instead with this additional
settings, we hide the gap length settings when automatic closure is
disabled.
Also it makes kind of a nice parallel with the "Manual closure" settings
which can also be enabled/disabled similarly.
Currently the option is quite simple. What should happen to make it more
usable:
* Right now, it uses the last stroke options (e.g. as used in a
previously run "Stroke Selection" or "Stroke Path"). We should have
some dedicated GUI in the bucket fill options.
* The bucket fill options GUI should really be redesigned. The more we
add options, the less understandable it is.
* There is a question whether we want to just use whatever brush size is
being set or if we want to have it vary and follow the line art width
(since we have proper distance map, we could use this to tweak the
stroke per-coords).
As usual, this feature was suggested by Aryeom who was still very
saddened that despite all the fancy features in this tool, it is not
able to produce nice rendering. So she proposed that the tool could
stroke the fill region borders.
Many features can only be run on items belonging to an image, and in
particular attached. It makes sense, but in the same time, there are
often some types of processing you'd like to do in background on
temporary items, not visible in GUI, and without any undo steps.
You could work on buffers directly, but sometimes it's also nice to
attach the semantics of the various items, and reuse logics (in
particular class method implementations) already existing. So I am
adding a concept of "hidden items" which is where you'd put items in
some temporary processing state when you don't want them to go anywhere
visible publicly.
I'm going to reuse this code in other parts of the file so make it a
utils function.
While doing so, I'm also improving a tiny bit the formatting of lists.
XCF 17 includes the new visibility locks and the ability to add position
and alpha locks on layer groups.
I am going to push the various commits implementing these different
features together which is why we gather them as a single XCF version.
We want it to work whatever the level in the item tree. We only care
about whether the items are selected or not.
Also fixing the AppStream release tag for the description of this
feature.
Unlike other locks, visibility lock is less useful for locking a whole
hierarchy of item and their children. On the other hand, being able to
lock a group visibility while editing the children visibility is quite
useful.
It can be argued that layer groups can't be painted on, and that's
probably the original reason, but it's really just the same as "Lock
pixels". It is interesting to be able to lock alpha channels on a layer
group to simply lock all its contents alpha channels.
Since we are now allowed to move groups (which is the same thing as
multi-selecting all its children and moving them), it makes no sense
that this lock is disabled.
This works the same way as "Lock pixels" in that a locked grouped also
forbid moving children. And there was already some logics so that you
can't move a layer group if one of it's children is locked. So this lock
really works both ways and is a bit special.
Finally I cleaned up a bit the multi-layer selection logics and
messaging, as well as which lock to blink (similar to the previous
commit) for the "Lock position" case.
In particular, if painting on a layer whose parent's pixels are locked,
we were blinking an empty lock spot, which is confusing. Now
gimp_item_is_content_locked() will also return the proper item (when
relevant, i.e. when returning TRUE) which is locked. It may or may not
the same item as passed in (it may also be a parent item in particular).
GLib has a specific type of NULL-terminated string arrays:
`G_TYPE_STRV`, which is the `GType` of `char**` aka `GStrv`.
By using this type, we can avoid having a `GimpStringArray` which is a
bit cumbersome to use for both the C API, as well as bindings. By using
`GStrv`, we allow other languages to pass on string lists as they are
used to, while the bindings will make sure to do the right thing.
In the end, it makes the API a little bit simpler for everyone, and
reduces confusion for people who are used to working with string arrays
in other C/GLib based code (and not having 2 different types to denote
the same thing).

There were some comments claiming we don't care about thumbnail creation
errors, only thumbnail saving. It's not true. Thumbnail creation errors
are probably even more important (in this specific usage). For instance,
trying to debug a thumbnail load procedure, I had no clue on the error
even though our system was able to report the issue. It's not cool for
plug-in developers.
Now we will check the thumbnail creation error, write down the error
message on stderr and clear the error for the fallback round (using the
normal file load proc). Then if it errors out again, we will keep this
error as the finale one because it's probably more important if we can't
even open images than the unrelated thumbnail saving error. We will
still return the saving error if the load proc failed without error.
The line art algorithm is useful but not always accurate enough and
sometimes it can even be counter-productive to fast painters.
A technique of advanced painters which Aryeom uses and teaches when she
wants to close an area without actually closing the line art (i.e. the
non-closed line is a stylistic choice) is to close with a brush the area
on the color layer. It has also a great advantage over the line art
"smart" closing algorithm: you control the brush style and the exact
shape of the closure (therefore something you'd usually have to redo
with a closure made by an algorithm as you would likely not find it
pretty enough).
This new feature takes this technique into account. Basically rather
than relying on the closure algorithm, you would close yourself and the
tool is able to recognize closure pixels by the color proximity with the
fill color.
Final point is that this additional step is made after line art
computation i.e. in particular the target drawable is not added to the
sources for line art logics. This allows to stay fast otherwise the line
art would have to recompute itself after each fill.
This also shows why the previous commit of moving the line art object
was necessary, because a painter would likely want to move regularly
from bucket fill to a brush tool to create area closures and we want to
avoid recomputation every time.
… fill tool finalizes.
The idea is that you may want to quickly switch tool to do something and
back to the bucket fill for line art selection. If the input drawable(s)
did not change, the previously computed data is still valid, so let's
hang on the line art object a little longer.
Since we are resetting the input when we get back, we would still
recompute anyway *if needed*, and the line art object does follow
changes on the input pickable so we would not get any deprecated data
anyway. Still we move around ownership a tiny bit to optimize for
common case of tool switching.
In order not to keep forever this data (buffer and distmap in
particular) forever just because one tried the line art once, I add a
timer to free it after a few minutes.
Moreover it will be useful for other cases, such as being able to share
the same line art object with the fuzzy select tool (if we end up adding
the line art option there). In a coming commit, the usage will be even
more obvious for use case where you want to edit the filled area with
other paint tools, then back to bucket fill while not touching the line
art source layer.
Fixes#4333
If the checkbox is unchecked: dynamics falls back to "Dynamics Off",
the current dynamics name and its options are hidden in the UI.
If the checkbox is checked: dynamics is set to previously used one
or the default one, all dynamics options are seen in the UI.
Now the source images are in the build dirs.
Also:
- clean the EXTRA_DIST contents on autotools;
- add dependencies rules in meson gresources to make sure icons are
built before resource build;
- finally remove a duplicate build rule in Color Makefile.
We now save and load layer and channel item sets. Only missing set types
are path ones, but the whole path item is just its own exception in the
XCF format, and adding support for it, while keeping compatibility with
older XCF seem like a small headache. I could do it, but I actually
wonder if it is worth it. Would people really need to store sets of
paths?
Also this commit finally gets rid of any remnant of the old item "link"
concept (I think), so we are getting close to merging the branch.
I cleaned many remaining places where the concept of linked item still
survived.
On loading an XCF file with linked items, we are now going to create a
named sets for the linked items, allowing people to easily select these
back if the relation was still needed.
We don't remove gimp_item_get_linked() yet and in particular, we don't
save stored items into XCF files. This will come in an upcoming change.
- removing the GIMP_ITEM_SET_LINKED enum value.
- removing gimp_image_item_list_linked(). Now we should directly use
gimp_image_item_list_filter() instead.
- "preview-linked" option for transform tools is no more.
This should fix these errors when running `ninja test` or `make check`:

The 3 available formats are: simple text search, regular expressions and
glob patterns (cf. previous commit). I did a small step back from
previous commit by getting "is-pattern" property back in GimpItemList
instead of having this case as a value of GimpSelectMethod. The reason
is that it would render a useless value in the Preferences combo box.
Text search is the default.
… search syntaxes.
The layer tree view is only using regexp so far, but the core code is
updated to allow more.
Simple text search is actually a bit more than "simple". It implies
tokenization of the text, Unicode normalization and case-folding. It
will also search with ASCII alternatives when possible. This includes
things like non-accented ASCII characters matching accented variants
which is neat.
Now it's not perfect. For instance tokenization seems very limited to
writing systems with spaces or alike. In particular, I tested with
Japanese and since you would typically write without spaces, a whole
group of several words would be one token. Since the text search
algorithm only search from token start, this is quite a failure as you
can't search with intermediate words only.
