GimpPlugin improperly destroys proxies after each run of a temporary procedure.
A temporary procedure may pass reference to proxy to main procedure.
Proxies should live as long as the main procedure of a plugin,
or for an extension plugin, until only the extension main procedure
is on the procedure stack. More discussion in the issue.
Extract method gimp_plug_in_proc_run.
Call it from two new methods: main_proc_run and temp_proc_run,
which do more e.g. cleanup.
Extract methods for cleanup, main_proc_cleanup and temp_proc_cleanup
Add method is_proc_stack_empty
Though I am not fond of these macros for our core code (it makes the
code more cumbersome especially for using private data in derivable
types), this definitely makes sense for public API, since it would allow
easier modifications with less chances of messing API/ABI stability.
...to path.
Changes the names of
gimp_vectors_* () API to
gimp_path[s]_* (). Renames related files
to [path] instead of [vectors], along with
relevant enums and functions.
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.
...to paths.
Similar to d0bdbdfd, but covering the
app/core versions of the API instead of
libgimp. Changes the names of
gimp_image_*_vectors () API to
gimp_image_*_path[s] ().
Also renames some related functions such
as gimp_image_pick_path (). The next step
will be to rename the gimp_vectors_* () to
gimp_path_* ().
Refactor: extract method gimp_widget_free_native_handle.
This reduces duplication of code and encapsulates Wayland specific code.
Call the new function in more places.
This is expected to fix#11613 but it is hard to be sure
since the exact sequence of events in 11613 was never determined
and only reproduceable in some flatpak builds.
Calling the new function in more places also should eliminate leaks.
But I did not test there was a leak prior to this fix.
...to paths
Follow-up to d0bdbdfd. Changes all
gimp_vectors_* () PDB to gimp_path_* ()
and renames relevant PDB files from
vectors to path.
The next step will be to rename
GimpVectors in libgimp to GimpPath,
removing the last (public) trace of it.
...to paths
The first step in converting GimpVectors
to GimpPath. The PDB API for any
gimp_image_*_vectors () is now
gimp_image_*_paths ().
This commit only covers libgimp, and
the app/core versions will be renamed in
a following commit.
Functions creating a new GeglBuffer should trigger a warning if the
result if unused, because this is potentially a big memory leak.
Similarly objects created by functions creating new layers should be
handled (usually by adding the layer to the image with
gimp_image_insert_layer()), because they also come with a buffer and
possibly quite some important memory leak.
If the type is not registered, g_type_from_name() is not able to find
the GType from the type name.
Fixes:
> gimp_gp_param_to_value: type name GimpGroupLayer is not registered
Also add a bit more type handling code.
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! :-)
In most bindings, they would just result in the same signature as the
_get_ variants (which people have been used to, since the GIMP 2
series). Also I was told that apparently in some bindings where this
would make a different signature, the (skip) annotation could be ignored
anyway.
The original reason to skip these was because the new _list_ API were
introspected basically to a similar function signature, except with a
useless return value, at least in pygobject binding where the list size
was also returned.
Though it seems that in fact, only the docstring was wrong. The real
signature was apparently already the same.
See: https://gitlab.gnome.org/GNOME/pygobject/-/issues/352
Therefore since the _get_ naming is more consistent compared to other
existing function, let's re-integrate the _get_ functions for array of
items or images.
This basically reverts commit 15ec254148.
Same for gimp_procedure_add_aux_argument() and gimp_procedure_add_return_value().
We now have specific public functions for every supported type and it's
in fact much better to use them. The generic functions gave the feeling
that we could use any GParamSpec as procedure argument, whereas we in
fact depend on what the PDB support, and only these subtypes.
These were created because of some limitation/bug in pygobject, which is
now much better worked around by having specific functions for every
argument type supported by the PDB.
Resolves#11018.
Currently, babl formats are saved as strings when
passed as params. However, indexed palettes do not
use a "standard" encoding string but are created from
palettes (with a custom format). This results in an
error when we attempt to recreate the babl format from
the custom string encoding, as it doesn't exist at that
point.
This patch mitigates the problem by converting the indexed
color to RGB/A 8-bit when used in params. In the future when
indexed mode supports different color spaces and higher
precision, we will need to remove the hard coding. For now,
it solves the immediate problem.
With the new API introduced int d1c4457f,
we next need to port all plug-ins using
the argument macros to functions.
This will allow us to remove the macros
as part of the 3.0 API clean-up.
In order for Python plug-ins to be able
to create custom parameters like
GeglColor and GimpChoice, we need to
create actual functions rather than
using macros. A subsequent commit
will update all plug-ins to use them.
While setting a plug-in as transient usually worked, it was failing in
cases the plug-in's progress bar was not initialized (i.e. if
progress_init() was not called before setting the dialog transient).
This commit stores the calling display, core side too (libgimp side, the
plug-in already had the calling display ID information), and we use this
when a GimpProgress has not been created yet.
… native dimensions/ratio display by default.
Also adding gimp_vector_load_procedure_extract_dimensions() public
function allowing plug-ins to query the native size or ratio of a vector
file.
Previous gimp_procedure_run_config() was in fact only good for private usage
inside the various run() methods for the different GimpProcedure subtypes. The
problem with this implementation is that the returned config object is not
complete. For instance, for a GimpLoadProcedure, the "run-mode" and "file"
properties are not part of the config object so you cannot call a
GimpLoadProcedure with any of the gimp_procedure_run*() functions.
Note: we had some working usage, e.g. in file-openraster, but only because it
was running the load procedure as a GimpPDBProcedure whose returned config
object was indeed always complete!
As a consequence, I rename gimp_procedure_run_config() as an internal-only
function _gimp_procedure_create_run_config() and I create a new
gimp_procedure_run_config() which always return a full config with all
arguments.
It was a bad idea to bind width/height with pixel density. These are separate
things. You may want to set specific pixel dimensions while keeping a given
resolution.
Moreover I am now properly storing aspect ratio in the widget, otherwise with
integer computation, we are just losing too much precision and the ratio is in
fact changing constantly as you change dimensions.
The bogus 0×0 default values for width×height properties are only because we
don't know the real native size of the image. Once we have computed it, we can
change the param spec defaults, so that hitting "Reset to Factory Defaults" sets
width, height and resolution to the actual file's default values (if resolution
is not a metadata in the format, which is apparently the case for all vector
formats we currently support, then 300.0 stays the default resolution).
I'm moving the logic of choosing a correct default for width/height by adding an
"extract dimensions" callback in the procedure. The logic is that every vector
format out there should likely have metadata either for pixel dimensions or
physical dimensions, or at the very least for no-unit dimensions (ratio only).
Vector load procedures will have to implement only the extraction of such data
in a callback called by GIMP but not how to act upon them, so that we have a
common logic for all vector images.
I am implementing this callback first in the SVG plug-in, moving all the code
to extract dimensions (and improving it) in this callback.
Also I am deleting "file-svg-load-thumb" procedure. I could simply reimplement
it using the same code, but it looks to me like this is very useless for vector
formats to have a specific thumbnail procedure (unless it were to use very
specific metadata for faster result). This is vector data, just ask it directly
at the proper bounding box size.
This includes a new function gimp_prop_choice_radio_frame_new() which
creates GimpIntRadioFrame from GimpChoice properties.
GimpChoice GimpProcedure arguments are still creating a combo box by
default, but it is now possible to override this default behavior to get
a radio frame by calling first:
```C
gimp_procedure_dialog_get_widget (dialog, "arg-name", GIMP_TYPE_INT_RADIO_FRAME);
```
Some apps that write EXIF metadata, forgot to add the charset to
certain tags that require it. The main case is Exif.Photo.UserComment.
This caused us to show a warning about an invalid charset, in addition
to not showing it in our Metdata Viewer.
We fix this by reading the raw data for that tag when we encounter the
above error. The raw data is then validated as utf-8 and converted
to a string if valid.
We then resave this tag to our metadata to force it to have the
correct charset; that way we don't have to do any checking in other
places in our code.
Note: there are a few other tags that also use a charset. We may have
to check those too, eventually.
By defining `GIMP_DISABLE_DEPRECATED` when creating the GObject
Introspection file, we're actually not (or only partially) generating
some of the documentation of some files that are marked as deprecated.
One example that should now properly generate documentation is
`GimpFileEntry`.
As noted by Anders Jonsson, the wrong parameter description
was removed when the API was updated. Other aspects of the
descriptions were also updated to account for the change.
Port all plug-ins to retrieve the layers
directly from the image rather than
having them passed in. This resolves some
issues with introspection and sets the
foundation for future API work.
- Fix a few broken references and an inconsistent argument name.
- Add the new headers in the introspectable header list.
- Add a few missing class descriptions for GimpProcedure and subclasses.
Instead of filling default GUI for a specific type of plug-in procedure in
fill_list(), we add 2 methods:
* fill_start() is ensured to run once (and only once) before any fill_list()
code runs.
* fill_end() is ensured to run once (and only once) after all fill_list() ran.
This takes care of 2 kind of GUI bugs which we could have:
1. First if no explicit fill were run (i.e. neither gimp_procedure_dialog_fill()
nor gimp_procedure_dialog_fill_list() were ever run), then the default
interface would not be added to the dialog. Yet this case could happen when
we don't want anything else but the default GUI (this will be the case in the
upcoming file-wmf-load GUI).
2. Second if at the opposite, you fill several times fill functions (I hadn't
thought of this, but noticed some already started to do this in our ported
plug-ins), we obviously don't want the default GUI to be added several times
either.
As expected, it is made to reuse shared code for every GimpVectorLoadProcedure.
In particular, they all need to choose dimensions to load at, so we are sharing
a same GimpResolutionEntry widget logic everywhere now.
I am in fact still very unsure about the code logic for this widget by the way
for these reasons:
* It still puts too much emphasis on the "resolution" (pixel density) part,
which makes people believe it's important, while they should in fact choose
the pixel dimensions most of the time and not care about the pixel density.
* Right now we can't break ratio (which in fact was already impossible in most
vector format plug-ins we had). Do we want to add a chain and allow this?
* If we consider the pixel density as the one we want to set the document with
(which may not be the same thing as the one from when we load the document),
we also want to break link between width/height dimensions and pixel density.
Right now we can't (updating one field updates the others too).
* There is always this issue of precision with pixel density vs. pixel
dimensions because we don't necessarily find the same values when computing
from one side to another because of lack of precision and this confuses
people.
* Finally there is the question of multi-page documents (e.g. PDF) where the
chosen dimensions are the document dimensions whereas each page may have a
different size which has to be recomputed independently and this got me
off-by-one errors. I think I'll need to review a bit the logic, but I'll do
once I've ported all the vector format load plug-ins first to see the most
common usages.
The code comes from plug-ins/common/file-pdf-load.c and apparently it used to be
in libgimpwidgets (very long ago). I'm copying it to its own file and massively
improve the code (depending on property binding which makes the behavior much
more robust).
Still I left it as private because I don't want to say the API is finale without
having tested it a bit more. But eventually we should make it public for
plug-ins to use it directly too. When this happens, it should get back to
libgimpwidgets.
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).
When there is a very long comment shown in the export dialog, the
dialog expands horizontally. Possibly making it wider than your screen
instead of wrapping the text.
Let's set word wrapping for the text view. That way the text will
wrap at a reasonable length and use the multiline text view instead
of just the first line.
… since forever anyway!
GIMP used to have a second export dialog, a generically generated one, appearing
either before or after (depending on when gimp_export_image() was called) the
custom export dialog implemented by the plug-in code. This has been hidden deep
in code since forever (since version 2.8.0 in fact, I believe) and only kept
hidden behind an environment variable "GIMP_INTERACTIVE_EXPORT". I don't think
we'll ever revive this, so let's clean up.
In fact, not one, but in worst case even 2 more dialogs were hidden behind this
variable! The first dialog (confirm_save_dialog()) was a confirmation when the
selected drawable was a layer mask or a channel (and not a layer). Most export
code don't even seem to care about the selected drawables anymore anyway (cf.
issue #7370), except with gimp_file_save() non-interactively (issue #8855),
which is a real mess of inconsistency anyway.
The second dialog (export_dialog()) was listing the various actions to do on a
copy of the image to help the plug-in (e.g. merge layers/flatten image, etc.)
and possibly give choices to some of these actions. Though there is definitely
no reason to request this kind of thing anymore, especially for a short-lasting
image copy, the list of action could still be interesting in the future, not as
information of what is going to be done, but as information of the kind of data
loss of the exported format. I could imagine we want to be able to reuse such
information for generating types of data loss per format in the export dialog,
in particular in the context of my long-term export workflow refactoring (from
which resizing before export such as #2531 are part of, but the whole
refactoring project is much wider).
In the whole discussion of #5858, there will be the question on whether we don't
want plug-ins to be directly given a "ready-to-use" image depending on
capabilities they advertized in create_procedure().
