This property is currently only used for gimp_edit_blend() to control
how are computed distances. In the future, it could be used for more
functions making use of "gegl:distance-transform" operation, or even for
other algorithms, if relevant.
This new property obviously comes with 2 new PDB calls:
gimp_context_get_distance_metric() & gimp_context_set_distance_metric()
The enums have to be menually registered in pdb/enums-external.pl.
Currently supports enums from GEGL only.
Add enum GeglDistanceMetric as first external enum.
Our composite modes don't correspond directly to the Porter-Duff
operators after which they're named, and these names aren't too
descriptive anyway.
Rename the composite modes as follows:
Source Over => Union
Source Atop => Clip to Backdrop
Destination Atop => Clip to Layer
Source In => Intersection
Update relevant code, including UI text, enumerator names, function
names, and action names.
In gimp_plug_in_open(), use gimp_spawn_set_cloexec() to prevent the
parent's end of the read/write pipes from being inherited by the
spawned plug-in, instead of passing the corresponding file
descriptors to the plug-in as command-line arguments, and having
gimp_main() close them.
Adding new command-line arguments to plug-ins is problematic, since
their ability to handle them depends on their protocol version,
which is only communicated after the plug-in is spawned.
Regardless, this is much simpler.
In gimp_plug_in_open(), use gimp_spawn_async(), added in the
previous commit, instead of g_spawn_async(). See the previous
commit for the rationale.
Since gimp_spawn_async() doesn't provide a mechanism to perform any
cleanup in the child before exec()ing, move the closing of the
parent's end of the read/write pipes from the app to the plug-in's
gimp_main(), passing the relevant file descriptors to the plug-in
through argv.
Our own implementation is much better.
I don't make it into a GUI yet, but at least the CLI option will use the
new implementation in plug-ins as well, which will be quite useful.
... procedure call.
This is needed for plug-ins which depends on other plug-in's procedures.
If for instance, the second-level plug-in is interrupted interactively,
we don't want to process this as an error but as a cancellation.
Therefore we need to know the returned value of the plug-in. Currently
only way was to use gimp_get_pdb_error() but that was returning a
human-readable error, not a computer-processable error.
gimp_image_metadata_save_prepare() now back to suggesting metadata
flags, but this time with reasonnable base. It indeed uses the presence
of particular metadata, but also whether the preferences asks for this
metadata to be exported by default or not.
The returned flags should not be called "suggested" flags anymore.
Having metadata available in the work image does not mean we want them
exported absolutely, which can be a security risk, especially for the
metadata which are there from the imported image.
Add "clamp-input" (which clamps the input values to [0..1])
and "clamp-output" (which clips the final result to [0..1]),
properties, parameters and GUI to:
- GimpLevelsConfig
- GimpOperationLevels
- The levels tool dialog
- The gimp_drawable_levels() PDB API
The old deprecated gimp_levels() PDB API now sets both clamping
options to TRUE which restores the 2.8 behavior.
Also reorder some stuff in GimpLevelsConfig and elsewhere so the
levels parameters are always in the same order.
Update the dprod production of generated enum files to include
abbreviated value descriptions, as per the previous commits.
Add a comment for translators above the abbreviated descriptions,
specifying the full description they abbreviate.
... with several threads
Commit d8ae581703 didn't go far
enough in protecting GimpTileBackendPlugin against race conditions.
The underlying GimpTile cache is shared across all drawables, so we
must use a common lock for all instances of GimpTileBackendPlugin,
instead of one per instance.
Do just that -- replace the per-instance mutex of
GimpTileBackendPlugin with a global one. This makes
GimpTileBackendPlugin instances thread-safe w.r.t. themselves, and
w.r.t other GimpTileBackendPlugin instances. However, we don't aim
to make GimpTileBackendPlugin thread-safe w.r.t. other libgimp
functions at this point, since the original API has never been
thread-safe.
to gimp_base_compat_enums_init() and move its prototype from
gimputils.h to gimpbase-private.h; it's not supposed to be
public API even though it's callable from the outside.
Remove the invert-linear and invert-non-linear variants and simply add
"gboolean linear" to gimp-drawable-invert. This should actually be an
enum but I didn't find a good name right now...
and add gimp_drawable_invert_linear(). Also, finally deprecate
gimp_invert() and port all its uses in plug-ins and scripts to
gimp_drawable_invert_non_linear() so the result is the same.
glib-genmarshal was rewritten in glib 2.53.4, and as of now (2.53.6)
it has a bug where it unconditionally generates marshaler bodies,
even for standard marshalers, even with --stdinc. This causes
libgimpwidgets to define and export g_cclosure_marshal_VOID__INT()
and g_cclosure_marshal_VOID__OBJECT(), which upsets defcheck, and
breaks the build.
Work around this for now by using --header --body when generating
the marshal.c files, which includes the prototypes in the source,
instead of including the header ourselves. This is the only code
path where the new glib-genmarshal doesn't generate bodies for
standard marshalers. Note, however, that this usage is deprecated,
so we'll probably want to change it back once it's fixed.
...in both the core and libgimp.
Images now know what the default mode for new layers is:
- NORMAL for empty images
- NORMAL for images with any non-legacy layer
- NORMAL_LEGAVY for images with only legacy layers
This changes behavior when layers are created from the UI, but *also*
when created by plug-ins (yes there is a compat issue here):
- Most (all?) single-layer file importers now create NORMAL layers
- Screenshot, Webpage etc also create NORMAL layers
Scripts that create images from scratch (logos etc) should not be
affected because they usually have NORMAL_LEGACY hardcoded.
3rd party plug-ins and scripts will also behave old-style unless they
get ported to gimp_image_get_default_new_layer_mode().
this commit changes just those which make no difference to
functionality: property and object member defaults that get overridden
anyway, return values of g_return_val_if_fail(), some other stuff.
...protocol calls.
Some calls are waiting for answers, for instance plugin procedures, and
tiles which expects data and acknoledgement.
This would result in error messages such as:
"expected tile ack and received: 5" (5 is GP_PROC_RUN)
Typically because a thread would run a procedure while another would
receive tiles.
Commit 1e6acbd4e1 modified the
generated enum recipes to run gimp-mkenums from the source
directory, instead of the build directory, so that only the
basenames of the corresponding header files would appear in
the comment at the top of the generated files. This was a
mistake -- $(GIMP_MKENUMS) is expecting to be invoked from the
build directory.
Switch back to running gimp-mkenums from the build directory. To
avoid including the relative path from the build directory to the
source directory in the generated file, add a @basename@ production
variable to gimp-mkenums, which exapnds to the basename of the
input file, and use it instead of @filename@ in the recipes for the
generated enum files.
When regenerating an enum file, don't copy it back to the source
directory if it hasn't actually changed. This allows using a read-
only source directory where the enum header is newer than the
generated file, as long as they're not really out of sync.
OTOH, *do* touch the generated source-dir file even when unchanged,
in order to avoid re-running its recipe on the next build, however,
allow this to silently fail (which is harmless).
We check them into git, so this makes it easier to keep them in
sync when using a separate build directory.
Case in point -- this commit also syncs a few enum files that went
out-of-sync with their headers.
Add "import-raw-plug-in" to gimprc, and a new procedure
gimp_register_file_handler_raw(). On startup, remove all load
procedures that are marked as "handles raw" but are not implemented by
the configured plug-in. Add the list of available plug-ins to prefs ->
import/export. Register all file-darktable procedures as handling raw.
Add a debug procedure group, living in 'debug.pdb', which would host
useful debug helper functions. Functions in this group are not part
of the stable API, and may be changed at any point.
All procedures added to 'debug.pdb' should have a 'debug_' prefix,
and use the new std_pdb_debug() macro, which adds the proper "here be
dragons" warning to their description.
Add two debug procedures: gimp-debug-timer-start() and
gimp-debug-timer-end(), which measure elapsed time, a la
GIMP_TIMER_{START,END}, and can be used to profile script-fu
commands.
It was agreed that we should write "plug-in" consistently. Only possibly
user-visible strings were updated.
Thanks to scootergrisen for a first patch which could not make it
after changing decision on the canonical writing.
