By doing this, I also add the ability to use a composited projection of
the selected drawables as source. This is similar to "Sample merged"
except that instead of using the whole visible image, we use what would
have been visible if only the selected layers existed.
Note that this doesn't work together with the previously added ability
of multi-cloning from each layer to itself. This ability works for
cloning from multiple layers to one.
- Make the various virtual methods of GimpPaintCore use a list of
drawables as argument instead of a single drawable.
- gimp_brush_core_eval_transform_dynamics() can work with an image as
argument rather than a drawable as it doesn't actually depends on
specific drawable data.
- New function gimp_paint_tool_enable_multi_paint() to be used in init()
method of paint tools to announce that this tool can work with
multiple layers selected.
- Use gimp_paint_tool_enable_multi_paint() in the GimpSourceTool base
class only for now.
This is a first step for multi-layer drawing, but we don't want it to be
possible in just any random cases, which is why I add a special function
to advertize this capability. We will use it for special-casing the
clone (as well as heal and perspective tools most likely) tool to work
on several layers at once. At this step, it is still very bugged and not
really working properly. In particular, since we don't process the
drawable offset early anymore (because it makes no sense when we pass a
list of drawables with different offsets), I suspect that all the
offset-related code will be very broken.
For the installer, we must also manually pull all used official
language, so I am adding a test checking that the list of pulled file
matches the list from the installer script.
Commit-triggered pipelines on `master` branch are apparently canceling
flatpak pipelines even though the flatpak jobs are not even in the
triggered ones.
In any case, these flatpak pipelines are not triggered often (only
through weekly schedule or manually triggered) so there is no need to
have such a flag.

If you first open a multi page TIFF, exiv2 generates EXIF tags for the
first 3 pages in the form of Exif.Image.<tags>, Exif.Image2.<tags>,
Exif.Image3.<tags>. When exporting with EXIF saving enabled, exiv2 thinks
it needs to save TIFF pages for the EXIF metadata of the second and third
page too. Those pages saved by exiv2 contain only metadata no real image
data and give warnings when loading.
The EXIF tags read from page 2 and 3 are only the basic image specs. We
don't use those, nor do we add tags to it. Until we support handling of
metadata for those pages and exiv2 has better support for all TIFF pages
beyond the first few, I see no reason to save this information.
So for now lets just delete all tags that start with Exif.Image followed
by a number.
On Windows there is a long standing issue in its File Explorer. When
GIMP exported as a multi page (multi-layer) TIFF with thumbnail saving
enabled, then the Windows thumbnailer apparently gets stuck and does not
close the TIFF file when browsing a folder. Because those files are not
closed it is impossible to delete them. This issue has been reported
many times over the years to Microsoft without any reaction.
Investigation showed us that this lock up only happens when we save the
thumbnail as a subifd. To resolve this issue we change this and now let
exiv2 handle our thumbnail saving, just as for other image formats. For
TIFF this means the thumbnail is saved as the second page of a TIFF.
Previous commits have made sure that it is now easier to recognize a TIFF
page as a thumbnail and to make sure we don't load thumbnail TIFF pages.
Since saving as a subifd is what made TIFF thumbnail saving different
from other formats, this commit consists of only removal of code.
TIFF image pages can specify what type of image that page represents.
If the page is marked as FILETYPE_REDUCEDIMAGE we will consider it to be
a thumbnail and filter that out of the list of pages that can be selected
to be loaded.
In addition to that we will try to recognize certain pages as thumbnail
that don't have the subfiletype tag set.
We will consider it a thumbnail if:
- It's the second page
- PhotometricInterpretation is YCbCr
- Compression is old style jpeg
- First page uses a different compression or PhotometricInterpretation
If these conditions are true the page will also be filtered out.
We could consider having an option whether to filter out thumbnail pages.
Since in the situation up until now we also don't load thumbnails, I think
this should be considered as a separate feature.
Since it appeared with GLib 2.68.0, we could not change this until we
bumped the dependency which has only become possible a few days ago
(since Debian testing is our baseline for dependency bumps). Cf.
previous commit.
As this is a drop-in replacement (just a guint parameter changed to
gsize to avoid integer overflow), search-and-replace with:
> sed -i 's/g_memdup\>/g_memdup2/g' `grep -rIl 'g_memdup\>' *`
… followed by a few manual alignment tweaks when necessary.
This gets rid of the many deprecation warnings which we had lately when
building with a recent GLib version.
GLib 2.68.0 was released on 2021-03-18 and has finally been added to
Debian testing (now that the release freeze is over!). So dependency
bumps are slowly going to happen again on the development branch.
Actually Debian testing has even 2.68.4, but it's a bit too recent and
2.68.0 is enough to get rid of some of the deprecation issues.
