This patch creates a GimpExportOptions class in both
libgimpbase and in libgimp. Currently it is a mostly empty
object, but it will be added to after 3.0 to allow for
additional export options (like resizing on export while
leaving the original image intact)
libgimp/gimpexport.c was removed, and most of its content
was copied into libgimp/gimpexportoptions.c. gimp_export_image ()
was replaced with gimp_export_options_get_image () in all
export plug-ins.
GimpExportProcedure has a new function to set the default
image capabilities for each plug-in on creation. It also sets up
a new callback function, which allows the options to respond to
user setting changes (such as toggling 'Save as Animation' in the
GIF or WEBP Plug-in).
This commit renames the GimpVectors
object to GimpPath in both app/core and
in libgimp. It also renames the files
to gimppath.[ch] and updates the relevant
build and translation files.
There are still outstanding gimp_vectors_* ()
functions on the app side that need to be renamed
in a subsequent commit.
Also:
- renaming gimp_layer_group_new() to gimp_group_layer_new() in order to keep the
same name as in core code (i.e. GimpGroupLayer, not GimpLayerGroup).
- renaming gimp_image_merge_layer_group() to gimp_group_layer_merge()
- new functions: gimp_procedure_add_group_layer_argument(),
gimp_procedure_add_group_layer_aux_argument() and
gimp_procedure_add_group_layer_return_value().
This can be tested, e.g. in Python with these calls:
```py
i = Gimp.get_images()[0]
g = Gimp.GroupLayer.new(i, "hello")
i.insert_layer(g, None, 1)
g2 = Gimp.GroupLayer.new(i, "world")
i.insert_layer(g2, g, 1)
g.merge()
```
This was work started long ago, stored in an old stash which I finally
finish now! :-)
It's still basic but will help to share code for support of various vector-able
formats, such as the logic for dimensioning them, but also the generated GUI.
Not only this, but we are paving the way for the link layers (though it'll be
after GIMP 3, we want plug-in procedures' API to stay stable) by giving a way
for a plug-in procedure to advertize a vector format support. This way, the core
will know when a source file is vector and can be directly reloaded at any
target size (right now, in my MR for link layers, the list of "vector" formats
is hardcoded, which is not reliable).
We pass 2 GeglColor through the wire now. Since it is passed very early
(when sharing the configuration), I had some issues with initialization
order of GEGL, and in particular when calling gegl_init() before
gegl_config() inside _gimp_config(), I had a bunch of such criticals:
> Plugin script-fu: GLib-GObject: CRITICAL: Two different plugins tried to register 'GeglOpPlugIn-transform-core'
Anyway in the end, I store the passed colors as raw bytes and strings in
the GPConfig object, and re-construct the GeglColor last minute in
_gimp_config().
These are not usable by plug-ins anymore which should store their data between
runs as arguments or aux arguments (in case of values which should be stored
from one run to another but are not really usable for non-interactive scripts).
These are per-plug-in (not polluting the whole process space with just random
strings as identifiers which could be used by other plug-ins) and even survive
restarts of GIMP.
I still keep these functions, but only internally, as they are used to store
settings of GimpAspectPreview, GimpDrawablePreview and GimpZoomPreview across
plug-in runs. Still I changed their API to set and return a GBytes directly
(mimicking the private PDB functions' API).
Also I remove gimp_pdb_get_data_size() which is useless when exchanging GBytes
directly.
Note that the 2 functions are still exported in the library, and only not
advertized through headers (so they are not really internal, just hidden), on
purpose, because we need to call them in libgimpui. So it is still relatively
easy for a plug-in to use them. Nevertheless I made clear in the function
documentation that these must not be considered public and could end up deleted
at any time. Any plug-in still trying to call these takes the risk of having
their code relying on unreliable API.
… function gimp_font_get_pango_font_description().
Also updating file-pdf-save which is the only plug-in using these right now.
Note that I am not fully happy with the new function
gimp_font_get_pango_font_description() because I experienced some weird behavior
in file-pdf-save which is that some fonts were wrong if this is called after
pango_cairo_font_map_set_resolution().
But let's say this is a first step looking for improvements.
Similar to the latest commits for GimpBrush:
- gimp_pattern_get_buffer() returns a GeglBuffer and allow getting a scaled
version of the pattern.
- Old gimp_pattern_get_pixels() is made private.
- Moved GimpPattern into its own file and store the buffer to avoid re-querying
it through PDB continuously.
No as for the widget to select a pattern:
- Preview frame ensured to be square.
- Default size increased.
- Drawing code using the new gimp_pattern_get_buffer().
- Cleaned up code.
… and gimp_brush_get_mask().
gimp_brush_get_pixels() was a bit crappy, returning raw data with only
dimensions and bpp to go with (no color model/space, no bit depth…). So the
assumption is that we work with 8-bit per channel data, possibly with alpha
depending of number of channels as deduced from bpp, and very likely in sRGB
color space. It might be globally ok with many of the brush formats (and
historical brushes) but won't fare well as we improve brush capabilities.
- gimp_brush_get_pixels() is in fact made private.
- The 2 new functions are using this old PDB call _gimp_brush_get_pixels() to
construct buffers. This has some limitations, in particular that it returns
only 8-bit per channel sRGB data, but at least the signature won't change when
we will improve things in the future (so if some day, we pass fancy brushes in
high-bit depth, the method will stay the same).
- This new implementation also allows scaling down the brush (keeping aspect
ratio) which is useful when you need to fit a brush preview into a drawing
widget.
- Current implementation stores the buffers at native size in the libgimp's
GimpBrush object, hence save re-querying the core every time you need an
update. This can be improved as current implementation also means that you
don't get updates if the brush changed. This should handle most common use
cases for now, though.
- Also with this change, I move GimpBrush class implementation into its own
dedicated file.
Much like for images and items. Change the PDB to transmit IDs
instead of names for brush, pattern etc. and refactor a whole
lot of libgimp code to deal with it.
modified: libgimp/gimpplugin-private.h
Simplifies chooser widgets (e.g. GimpBrushSelect) by eliminating attributes (e.g. opacity) of chosen resource.
See #8745, but this commit fixes that by first refactoring the code.
Refactors GUI widgets (e.g. GimpBrushSelectButton and GimpBrushSelect etc.)
Refactor by "Extract class" GimpResourceSelectButton from GimpBrushSelectButton etc.
This moves common code into an inherited class (formerly called GimpSelectButton)
but the subclasses still exist.
The subclasses mainly just do drawing now.
Refactor by "Extract module" GimpResourceSelect from GimpBrushSelect etc.
Moves common code into one file, generic at runtime on type of GimpResource,
that is, the new code dispatches on type i.e. switch statements.
In the future, when core is changed some of that can be deleted.
The files gimpbrushselect.[c,h] etc. are deleted.
The module adapts the API from core to the API of callbacks to libgimp.
Note that core is running the resource chooser (select) widgets remotely.
Core is still calling back over the wire via PDB with more attributes
than necessary.
The new design gets the attributes from the resource themselves,
instead of receiving them from core callback.
The libgimp side adapts by discarding unneeded attributes.
In the future, core (running choosers for plugins) can be simplified also.
Fix gimp_prop_chooser_brush_new same as other resources.
Finish changes, and clean style.

Cleanup from review Jehan
Now text layers are proper types, which means that the binding API will also be
nicer (e.g. `txt_layer.set_text('hello world')` in Python).
This commit also adds the param specs allowing to create plug-in procedures with
text layer parameters.
Finally it fixes the few calls in file-pdf-save (apparently the only plug-in
using specific text layer API right now) with explicit type conversion.
Reviewer (Jehan) note: cherry picked from MR !274. Still deciding
whether this will be pushed to gimp-2-10 branch too.

Saving a thumbnail is closely related to the other metadata preferences,
but so far this was the only one that didn't have a preference for a
default user value.
This commit adds a preference in the metadata section where a user can
select whether thumbnail saving is enabled by default or not.
gimpimagemetadata.[ch] was built into libgimpui because GTK+ was used
for dialog query for rotation metadata. gimpimagemetadata-save.c only
was built into libgimp, which made no sense as the declaration for its
public function was inside gimpimagemetadata.h!
That was a weird situation and somehow only made visible in the build
system because GIR build was complaining about missing annotations to
gimp_image_metadata_save_prepare() (the annotation was actually present
but in the implementation which was not in the same library as the
header, how weird!):
> Warning: GimpUi: gimp_image_metadata_save_prepare: return value: Missing (transfer) annotation
Moreover it means that only plug-ins linking libgimpui had access to the
gimp_image_metadata*() API, which is obviously not cool (that should be
a core API).
Instead I moved everything into libgimp and replaced
gimp_image_metadata_load_finish() with
gimp_image_metadata_load_finish_batch(), which is essentially the same
function except that it's not interactive (it will proceed to rotate the
image without user confirmation, provided the right flag is present).
Then I add gimpimagemetadata-interactive.[ch] which contains only
gimp_image_metadata_load_finish() and is the alternative interactive
version of gimp_image_metadata_load_finish_batch(). Most plug-ins won't
even have to be changed (at least none in core GIMP) and would still
work as before, whereas now a non-interactive version exists, which
doesn't mandate to link GTK+.
We're exposing symbols in our header files like `GType`, `GFile` and
others, without actually including the proper headers. This also gives
errors in the GIR scanner (who can't resolve those symbols).
export it to libgimp via GPConfig and add new API gimp_export_comment().
Bump the protocol version and improve variable names in both GPConfig
and libgimp/gimp.c.
Break reference cycles between the objects and the procedures they
keep by moving procedure destruction to dispose() and calling
g_object_run_dispose() before unrefing PLUG_IN and PDB in gimp.c.
Also some formatting and "Since: 3.0" annotation .
No need of is_id_arg() anymore in pdb/lib.pl. Let's reuse the {id}
value. Also I had to add an additional trick for GimpDisplay which we
will now generate as such in libgimp PDB files, but still need to show
as GimpObject on app/pdb/.
As previously, only the new classes and the PDB generation for a first
step.
which looks much like gimpconfig-params.h and contains macros
(e.g. GIMP_PROC_ARG_BOOLEAN() and GIMP_PROC_VAL_BOOLEAN()) for all
GimpProcedure argument and return value types supported by the
protocol, and makes the boilerplate of setting up a procedure more
readable and much less indented.
This file is C-only and not introspected.
which are GimpProcedure subclasses with API to register as load/save
handlers and their own kind of run functions that get their standard
arguments passed directly instead of packed into a GimpValueArray.
They also register their standard arguments themselves, which removes
quite some boilerplate from load/save plug-ins.
Remove gimpprocedure-private.[ch] because install() and uninstall()
are now virtual functions of GimpProcedure.
The idea is that we already have a GimpProcedure object in libgimp
which has name, help, blurb, arguments, return values and everything,
so we really don't need a parallel API to query PDB procedures for
their properties.
- make run() a virtual function of GimpProcedure
- move GIMP_PDB_ERROR to GimpPDB
- GimpPDBProcedure is a trivial subblass which populates
GimpProcedure's members by querying the PDB.
- make "plug-in", "procedure-type" and "name" construct-only
properties of GimpProcedure.
This is all work in progress.
Start copying all the actual wire communication to GimpPlugIn, and
move the legacy versions to gimplegacy.c.
This implies having the entire protocol code twice, but without any
if(PLUG_IN) { plug_in_stuff(); } else { legacy_stuff(); }
At the moment it is a wild mixture of old and new, but when finished
the wire code in gimplegacy.c will be entirely separate from the wire
code in GimpPlugIn, which will make it easy to g_assert() that only
one API is used by a plug-in.
which must be called by GIMP_EXTENSION procedures when they are ready
to run their temporary procedures. Move gimp_extension_ack() to
gimpobsolete.[ch].
which takes and returns GimpValueArrays. This or something similar is
the new central function for running core procedures. Use the new
function from gimp_run_procedure2().
The `data` property of a GimpParam is a union. Unfortunately setting a
union is not supported by GObject Introspection yet. So I create some
APIs to create GimpParam-s from values. Note that this is temporary API
(i.e. it may be removed before GIMP 3 release) since we likely won't use
this GimpParam type anymore with the new plug-in API. But for now, this
is necessary, at least for testing and porting Python plug-ins.
Also for GimpParam to be actually introspectable, I had to make it a
boxed type, but since no length information is available for various
variants of the type (arrays, whose length information is a separate
parameter), the copy and free functions are basically broken or leaking
respectively for all types requiring a length.
Bottom line: this is ugly and we really need a new introspectable
parameter type. But for now, it allows to start porting some of our
Python plug-ins.
