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().
… test-color-parser.c file.
The file libgimpcolor/test-color-parser.c was compiled but never actually called
by the build. Now that we have a nice infrastructure to test libgimp API, I am
moving it there with the new format. Doing this also allowed me to discover some
bugs in CSS parsing, as well as discover Python binding was failing here (cf.
the few previous commits).
Only one test is disabled so far, the one where 4 digits are used per channel in
hexadecimal notation: "#64649595eded". This format simply doesn't appear
anywhere in the spec, and also the result values in the samples listing don't
even fit. So far, I'm just unsure what to do with it, if we want to keep this
support (of some kind of higher precision hex notation, but not specified, so is
it even used by anyone?) or not.
All the other tests just work in both C and Python!
This is meant to obsolete GeglParamColor with at least an additional argument
has_alpha which we need in GIMP. It allows to advertize when a parameter wants
an opaque color, which in particular means we know when displaying a GUI to pick
colors with alpha or not.
In some binding (e.g. Python), we have not found how to create GeglParamColor
specs for PDB procedures, so we use GParamObject specs with `GeglColor`
object_type. Have our code handle both variants.
Fixes:
> GIMP-WARNING: _gimp_gp_param_def_to_param_spec: GParamSpec type unsupported 'GeglParamColor'
Of course such generic spec won't have any future option which we may add to a
dedicated param spec (and despite adding code to handle a default value, adding
a default color still doesn't work according to tests).
There are no plug-ins which uses GimpRGB for procedure argument, nor is there
any base PDB procedure. We don't pass this type anymore through from/to
core/plug-ins. So let's clean the whole code out as a next step to get rid of
GimpRGB from our codebase!
The comment I had written back then was wrong. Meson in fact can create an env
object from another with a simple assignment (which copies the object, rather
than pointing to a same object), per the answer which has been given to me in:
https://github.com/mesonbuild/meson/issues/13045
This allows to have a properly separate environment (when using GIMP as a build
tool, we don't want to load the test files).
The previous commit worked for all the compiled executables, but for Python
plug-ins (and likely all other GObject-Introspected bindings), we need to
generate a temporary typelib linking to the in-build-directory libgimp*
libraries.
This is similar to what the script `package/macports_build_app.sh` does for
packaging in gimp-macos-build repository.
Calling gimp_selection_float from a Python plug-in could make it crash
with an error like Calling error for procedure 'gimp-selection-float':
Item x cannot be used because it is not a group item.
This is caused by an incorrect check for group layers.
gimp_pdb_item_is_group returns an error when the condition is False,
while we only want an error when a group layer is selected (True).
Thus we need to use gimp_pdb_item_is_not_group, which returns an error
when the item is a group, which is what we want.
These function names are a little confusing, we might need to think
about better naming sometime.
I added C/Python tests for this function, so that we can test whether
this works correctly.
Without this, there is no easy way to quietly check for existence of a resource by name.
Needed when plugin authors can name defaults for resource args by name.
Add tests to script-fu/test/tests
Mainly fixing GimpRGB comments and
parameters that are unused (or in unused
functions).
GimpCircle and GimpGradientChooser
have color conversions ported to use
GeglColor exclusively.
- Replaces GimpRGB in Channel Dialog
with gdouble array, as was done in
channel_options_color_changed ()
- Replace %ld with G_GSIZE_FORMAT
in libgimp checkboard color message to
fix warning in Windows build
- Set file-gih documentation text as
translatable.
Resolves#10992.
GimpTextLayer's color attribute was
updated from GimpRGB to GeglColor,
but gimp-text-layer-set-color still passed
in GimpRGB. This patch updates the PDB
call to match the property type.
Most of the C boiler-plate code is generated so that all you have to do is
implement the run() function with test code in it.
Also adding a README to make it all very clear and easy to add new tests.
With Python binding, it gets very easy to test new functions. I've been
wondering if we need C counterparts, but really since it's a GObject
Introspection binding, if a function succeeds there, it should also succeed in C
code.
For now, I'm testing a few of GimpPalette API. Not all of it yet. Also I test
both the direct C binding and PDB procedure since in some cases, one or the
other may not properly working. See #10885.
We were missing GimpColorArray support in one function. Note that the specific
example in Python in #10885 still doesn't work, but for a second reason:
gimp_value_array_index() returns a GValue which pygobject automatically tries to
transform to the contained data. And unfortunately it doesn't know about our
GimpColorArray type so we end with unusable boxed type generic data.
Since the color space invasion, GimpRGB
properties do not create widgets anymore.
For Python plug-ins, we need to add
GeglColor properties as GObjects with
GeglColor value types as a workaround.
This patch does this and updates the
Foggify plug-in with the new datatype.
Though I had already implemented passing GeglColor through the PDB, it was not
complete. In particular, the protocol was not able to pass GeglParamColor specs.
Fixes:
> LibGimp-WARNING **: 16:06:09.451: _gimp_gp_param_def_to_param_spec: GParamSpec type unsupported 'GeglParamColor'
This is part of the fix to issue #10811, though it's not complete yet.
I still see some limitations in GimpGradient, and in particular, they are still
always stored as RGB in GGR files. It would be nice if we could store the actual
color format. This way, if someone chooses a gradient stop as Lab or CMYK color,
that's what the gradient file would keep track of. But also even storing the
space of a color (instead of storing/loading always in sRGB, even though this
may still work fine as we store unbounded double values). This might warrant for
a v2 of GGR file format.
This commit also fixes loading of SVG gradient which was apparently broken
regarding hexadecimal color parsing.
Finally I improve gegl_color_set_alpha() by adding an alpha channel when the
initial format had none.
The invasion extended to some core widgets too, in particular GimpColorPanel (a
subclass of GimpColorButton). There was quite a lot of code depending on these
widgets.
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().
One of the big improvement in this commit is that text layers are now much
better at space accuracy. They were already space-aware, yet rendered as sRGB u8
only before being converted to the image's space. It means that text layers had
the following limitations:
* Any color out of sRGB gamut were trimmed.
* Precision was always 8-bit (even if the image was high-bit depth).
Now GimpTextLayout keeps track of its source space (for RGB and CMYK only, this
won't be as easy when we will support more backend, since Cairo has only RGB
support for image data) and the image TRC (in case it bypasses the color space's
TRB) and it draws within this gamut and space.
It means first that we are not limited to sRGB colors; we will draw text main
color in the full image gamut, with still 2 remaining limitations:
* Unbounded colors are impossible because Pango format (to color text) uses
hexadecimal (so even with half/float images, you can't draw out-of-gamut text
unfortunately).
* Main color precision is still 8-bit, yet a tiny bit better than before as we
at least follow TRC (so we avoid some of the precision loss when converting,
even though the bit-depth is still the biggest loss).
The outline color on the other hand is drawn through Cairo API entirely, in
float. This means that the outline color will now be without any precision loss.
Note that this depends on CAIRO_FORMAT_RGBA128F which is only available since
Cairo 1.17.2 which is not in Debian bookworm (our current baseline for GIMP
3.0). It means that the old precision will still happen with older Cairo
version, as determined by #if code at compilation.
- app: gimp_context_get_(foreground|background)() are now returning a GeglColor.
- libgimp: PDB functions named similarly in libgimp are returning a newly
allocated GeglColor too.
- A few other PDB functions (the ones using these functions) were updated and
their signature changed to use GeglColor too, when relevant. Plug-ins which
use any of the changed libgimp functions were fixed.
- GimpContext: signals "(foreground|background)-changed" are now passing a
GeglColor.
- libgimpconfig: new macro GIMP_CONFIG_PROP_COLOR using gegl_param_spec_color().
- GimpContext: properties "foreground" and "background" are now GeglParamColor
properties.
- app: All code interacting with GimpContext objects were updated to receive a
GeglColor (that they may still convert, or no, to GimpRGB for now).
- app: gimp_prop_gegl_color_button_new() was added as an alternative to
gimp_prop_color_button_new() when the property is a GeglParamColor. Eventually
the former should replace completely the latter.
- libgimpwidgets: gimp_prop_color_area_new() now works on GeglParamColor
properties only.
- libgimp: gimp_procedure_dialog_get_widget() will generate a GimpColorArea for
GeglTypeParamColor arguments.
Also the color is internally stored as GeglColor, though there are still get
APIs and signals using GimpRGB.
The equivalent PDB functions are also changed to use GeglColor, same as app/
functions.
This is a first commit to really getting rid of GimpRGB within core and
PDB/plug-in code. This will make color conversion reliability a lot better as
GeglColor will handle conversions for us. The goal is that we should keep origin
color space (for instance when picking colors in a GimpPickable, or when storing
in the FG/BG colors or in paletters) until the last second and convert at use
only.
It's still very much work-in-progress.
These 2 functions were removed in commit 89c359ce. They were in fact used and
clearly this historical API seems interesting (though we can likely do the same
thing using the drawable GeglBuffer, but this way is much easier).
This is now reimplemented using GeglColor instead of raw data.
Eventually this is meant to fully replace GimpRGB (as well as GimpHSV, GimpHSL
and GimpCMYK), both in libgimp and in core code, as part of both the space
invasion and the API rework. For this first commit, I keep this new object side
by side to GimpRGB.
MINGW64
- uses 0x601 as value for _WIN32_WINNT. No need for us to define
it to that value or even lower values in some places.
This also gets rid of: warning: "_WIN32_WINNT" redefined
- has 0x0502 for WINVER, so get rid of us setting it to 0x0500 in
gimp-app-test-utils.h. It also seems that the need to use G_OS_WIN32
has disappeared here.
- DIRECTINPUT_VERSION is 0x0800, no need for us to set it to that value.
- AI_ADDRCONFIG was apparently missing from the MINGW headers in the
past, but not anymore.
- Do not leak allocated return value of gegl_node_to_xml_full().
- When merging layer effects, use gimp_drawable_filter_commit(), making
sure we use the exact same code path as when applying layer effects
destructively from the start. This also ensures that filters are
properly removed from the filter stack (unlike
gimp_drawable_merge_filter()), which was the reason why the rendering
was wrong (hence getting the buffer without effects first, then
reapplying it after was only a workaround to an actual bug).
- When removing a filter, verify the object still exists before doing
anything with it. If this was the last reference, we don't want to
call functions on this object. In gimp_drawable_filter_commit(), we
set up a weak pointer. In gimp_drawable_filter_remove_filter() itself,
we save the pointer to the filter's drawable before actual removal (as
we don't want to dereference a freed object later on).
- export_merge_layer_effects() should merge filters recursively through
layer groups.
- clean up the XCF code:
* No need to wrap the effect pointers list into 2 zero offset. Only
have one zero offset to indicate the list end.
* Add the layer effect mask in the effect structure (not in the layer
structure), similar as for layer masks.
* Effect name and icon made as main data in the structure, not as
properties.
This patch implements an initial form of
non-destructive editing. Filters now stay active
instead of being immediately merged down.
A new column is added to the layer tree view, which
can be clicked to show a pop-over menu.
Filters can currently be hidden/shown, edited, reordered,
deleted, and merged down from this pop-over menu.
Currently, this works on layers and layer selections only.
Plenty of room for improvement!
Resolves#10651
The "Remove All Guides" script calls
gimp-image-find-next-guide, which per
its description can take in 0. However,
the parameter sets 1 as the minimum
value.
This patch fixes the range so that it can
accept 0, which enables the Remove All
Guides script to work again.
It also updates the script to the new
multi-layer aware API.
Due to GObject Introspection we can't have the last part of an
identifier start with a digit, since that part will be used in Python
as the identifier, and Python doesn't allow that to start with a digit.
e.g. GIMP_ROTATE_90 would be used in Python as
image.rotate(Gimp.RotationType.90)
To fix this we add DEGREES in front of the number, without a '_',
even though that looks ugly.
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.
gimp_procedure_new_return_values() takes ownership of the passed GError (it
allows, among other things, to call it directly as return value). So we must not
try and free it afterwards.
The gimp_procedure_run() already existed, though it was with an ordered
GimpValueArray array of arguments. Its usage feels redundant to the series of
gimp_pdb_run_procedure*() functions (which is confusing), but
gimp_procedure_run() was actually a bit more generic, because it does not
necessarily calls GimpProcedure-s through the PDB! For instance, it can runs a
local GimpProcedure, such as the case of one procedure which would want to call
another procedure in the same plug-in, but without having to go through PDB. Of
course, for local code, you may as well run relevant functions directly, yet it
makes sense that if one of the redundant-looking function is removed, it should
be the more specific one. Also gimp_procedure_run() feels a lot simpler and
logical, API wise.
A main difference in usage is that now, plug-in developers have to first
explicitly look up the GimpPdbProcedure with gimp_pdb_lookup_procedure() when
they wish to call PDB procedures on the wire. This was done anyway in the
gimp_pdb_run_procedure*() code, now it's explicit (rather than calling by name
directly).
Concretely:
* gimp_pdb_run_procedure(), gimp_pdb_run_procedure_config() and
gimp_pdb_run_procedure_valist() are removed.
* gimp_procedure_run() API is modified to use a variable args list instead of a
GimpValueArray.
* gimp_procedure_run_config() and gimp_procedure_run_valist() are added.
* gimp_procedure_run_config() in particular will be the one used in bindings
which don't have variable args support through a (rename-to
gimp_procedure_run) annotation.
Passing (name, type, value) triplets is actually useless because we can get the
type information from the procedure/config anyway. That only adds one more
verification to do. Let's just change the function so that we pass (name, value)
couples instead, pretty much like in `g_object_set()`.
As far as plug-in API is concerned, at least the calling API, order of arguments
when calling PDB procedures doesn't matter anymore.
Order still matters for creating procedures with standard arguments (for
instance, "run-mode" is first, then image, or file, drawables or whatnot,
depending on the subtype of procedure), but not for calling with libgimp.
Concretely in this commit:
- gimp_pdb_run_procedure_argv() was removed as it's intrinsically order-based.
- gimp_pdb_run_procedure() and gimp_pdb_run_procedure_valist() stay but their
semantic changes. Instead of an ordered list of (type, value) couple, it's now
an unordered list of (name, type, value) triplets. This way, you can also
ignore as many args as you want if you intend to keep them default. For
instance, say you have a procedure with 20 args and you only want to change
the last one and keep the 19 first with default values: while you used to have
to write down all 20 args annoyingly, now you can just list the only arg you
care about.
There are 2 important consequences here:
1. Calling PDB procedures becomes much more semantic, which means scripts with
PDB calls are simpler (smaller list of arguments) and easier to read (when
you had 5 int arguments in a row, you couldn't know what they refer to,
except by always checking the PDB source; now you'll have associated names,
such as "width", "height" and so on) hence maintain.
2. We will have the ability to add arguments and even order the new arguments in
middle of existing arguments without breaking compatibility. The only thing
which will matter will be that default values of new arguments will have to
behave like when the arg didn't exist. This way, existing scripts will not be
broken. This will avoid us having to always create variants of PDB procedure
(like original "file-bla-save", then variant "file-bla-save-2" and so on)
each time we add arguments.
Note: gimp_pdb_run_procedure_array() was not removed yet because it's currently
used by the PDB. To be followed.
This partially revert some of the changes in commit 652a1b4388 because the
Windows CI suddenly failed because of this (my local build on Linux didn't have
any problem though) with:
> /usr/bin/x86_64-w64-mingw32-ld: libgimp/libgimpui-3.0-0.dll.p/gimpproceduredialog.c.obj: in function `gimp_procedure_dialog_save_defaults':

> /builds/GNOME/gimp/_build/../libgimp/gimpproceduredialog.c:368:(.text+0x11b1): undefined reference to `_gimp_procedure_config_has_default'
This is because these functions are used not only inside libgimp but also
across inside libgimpui. As a consequence, the build fails when linking
libgimpui.
This goes with our planned change of not making GimpProcedure arguments order
relevant anymore regarding the PDB API. In particular, it means we don't want to
use GimpValueArray for various procedure arguments API, but directly
GimpProcedureConfig objects.
This change will allow to add or reorder arguments in the future, so that we
won't have to create new PDB procedures when adding new arguments, while still
keeping PDB API stability.
Some of these should not even be visible by libgimp and were just fine as static
as well! For the rest, I make them really private (not only with a private
header).
We cannot be 100% sure generically (i.e. for all possible bindings available
with GObject Introspection) if bindings add their own reference to objects or
not. Clearly we have cases when they always do (Lua, Javascript), cases when
they do only in certain conditions (global Python variables) and cases when they
don't (Vala). What we know for sure is that in these script languages,
developers don't manually manage memory anyway. So the additional reference is
not their fact.
So let's just maintain a list of automatic memory managed binding languages,
among the few we officially support (i.e. the ones for which we have working
test plug-ins) and verify by executable extension if the plug-in is written in
one of these.
Both keeping a manually-updated list and verifying by extension are not so
pretty solution, but for now it will do.
As explained in the comment above, the reference might actually be owned by the
binding code (not by the plug-in code) and therefore can still be released
afterwards. Freeing it now while we don't own the reference exposes us to
double-free crashes.
Until now, it was not really possible to delete a colormap color, but since we
now use GimpPalette, people would definitely try to do so. It just makes sense
to allow doing this, but only if the color is unused.
Additionally when we do this, all the pixels refering to bigger indexes will be
edited so that they continue to refer to the same color (bigger indexes are
shifted by -1). Therefore removing an unused color does not change the image
render.
I wondered if we might want more options, e.g. the ability to delete a color
without fixing indexes (i.e. that colors over the deleted color index would
shift to the next color). This would even allow to delete used colors (though
now the last index would have to be unused one, unless we cycle colors).
Yet I don't think this should belong to this basic API. The most expected
behavior when deleting a color from an image colormap is to fix all indexes
stored in pixels so that the image still shows the same. So that's what this
function will do in this generic usage.
This is meant to replace gimp_image_get_colormap() (see also #9477).
We likely won't need a gimp_image_set_palette() because we can simply edit the
image's colormap/palette with GimpPalette API now and it is directly updated.
For instance, the following code changes the first entry in the image palette to
red, immediately:
```python
i = Gimp.list_images()[0]
p = i.get_palette()
c = Gimp.RGB()
c.r = 1.0
p.entry_set_color(0, c)
```
For this to work fine, I added a new concept to GimpData, which is that they can
be tied to a GimpImage (instead of a GFile). Image palettes are not considered
internals, they are just tied to their image, therefore they can be edited by
scripts/plug-ins.
Additionally with this commit, editing an image's colormap from libgimp API also
generates undo steps now.
bootchk had the case in commit 6781a35668. I again had it with gfig. I think it
just makes sense to init GEGL, especially as the errors are not that explicit
and that the plug-in code may not even call GEGL code directly (so it makes it
harder to guess).
It returns all the fonts (possibly more than 1) with a given name. I left the
function gimp_font_get_by_name() as a utility when one don't want to choose (or
is not able anyway, e.g. a script with minimal information), though I wondered
if we should not simplify with a single function (the new one, which is the
correct one now that it is possible to have several fonts with a given name).
It is easy to test with fonts named the same. For instance I could find 2
different fonts, both named 'Holiday'. This call in the Python console returns
both:
> Gimp.fonts_get_by_name('Holiday')
As part of this commit, I also implemented resource arrays (or subtype arrays)
as PDB arguments and return types.
… description.
- The returned value as width/height/etc. of the glyph extents (or bounding
box), not "of the font" (which doesn't mean much).
- Adding some definition for ascent and descent. This text is straight out
copied from Pango documentation comments in pango/pango-types.h.
- I don't see why we were negating the descent value. Let's keep the value sign
as defined in Pango.
- Fonctions were renamed: s/gimp_text_fontname/gimp_text_font/ and
s/gimp_text_get_extents_fontname/gimp_text_get_extents_font/
- The size_type arguments were removed. Even in 2.10, this argument was marked
as "dead" and ignored. It was only kept for API compatibility.
- The font name (string) was replaced by a GimpFont argument.
gimp_text_font() is easily tested in the Python console with:
> Gimp.text_font(Gimp.list_images()[0], None, 10, 40, "Hello World!", 1.0, True, 100, Gimp.context_get_font())
And gimp_text_get_extents_font() with:
> Gimp.text_get_extents_font("Hello World!", 100, Gimp.context_get_font())
Fixing:
> [809/2421] Generating libgimp/GimpUi-3.0.gir with a custom command (wrapped by meson to set env)
> libgimpwidgets/gimppropwidgets.c:37: Warning: GimpUi: multiple comment blocks documenting 'SECTION:gimppropwidgets:' identifier (already seen at gimppropwidgets.c:23).
This function is not perfect and in particular doesn't seem usable with binding
because of GimpUnit being some weird mix between an enum and some kind of class.
So this will have to be fixed too. See #8900.
… 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.
I am using the same GimpDrawableChooser with an additional drawable_type
argument to only show the appropriate tab if we want to limit what can be
chosen.
None of our plug-ins actually use a GimpLayer or GimpChannel only arg so far,
but if we have some day, or if some third-party plug-ins want to have such arg,
now they quite easily can!
After testing, setting a window as transient to another from another process is
still broken on Windows and it's hard to diagnose without using Windows
directly. Since it's not just broken, but it even hangs the whole process, which
is quite a blocker issue, let's disable again the whole code on Windows.
This was not working properly and needed some external build script as well as
the stamp/bogus header trick like for other similar in-source generated code.
In the same time, I get rid of old meson code which was meant for when using
meson < 0.57.0 (since our requirement is now meson >= 0.59.0).
I believe it should not happen in normal GUI case (which is when you create a
GimpProcedureDialog). I had the issue while moving around some plug-in code and
moved dialog creation before gimp_ui_init() by mistake. The issue was not
obvious until I followed the trace inside libgimp. This would be even more
frustrating for plug-in developers so let's have a clear warning message giving
the possible plug-in crash reason.
Similarly to the various GimpResource select PDB calls, this allows to call a
core dialog in order to choose a drawable which will be returned back to the
calling plug-in.
This new GimpPickableSelect dialog is a subclass of GimpPdbDialog and uses the
same GimpPickableChooser widget as GimpPickablePopup, except that since it's
inter-process window management, it is harder to make a popup positioned
accurately relatively to a parent (especially on Wayland). This is why it's a
separate widget as a simpler dialog (which we will still try to make transient
as much as possible across platforms).
This name was really irking me because it's not a button (anymore? Maybe it used
to be just a button). Depending on the specific widget, it will have several
sub-widgets, including a label. And it can theoretically even be something else
than a button.
So let's just rename these widgets with the more generic "chooser" name.
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.
So what I realized was that the core was sending contents without transparency.
Actually the mask was our transparency channel here. Since in most use cases,
what you want to do when you request a brush buffer is to be able to draw it
somewhere, having a buffer already with alpha is much better, even more because
by default, it looks like background color is black which is possibly not what
you expect usually from a brush preview.
If someone wants absolutely no-alpha, it's easy to get rid of the channel. It's
simply better that the default behavior is the most expected use case.
- Increase the default size to 40x40 and multiply it by the current window scale
factor to have decent preview size.
- Make the brush preview always square with a GtkAspectFrame: even though
brushes are not necessarily square, this is a much more obvious size rather
than letting GTK choose a random allocation size which ends up very weird
looking.
- Scale down the brush to the biggest possible dimensions which fit the square
preview area (if the brush native size is already smaller, I don't scale up
though) while keeping aspect ratio: previous implementation was really weird,
as we were only seeing a tiny corner of much brushes as we weren't scaling
them down. Obviously I use new gimp_brush_get_buffer|mask() functions for
this as it supports scaling.
- Implement drawing color brushes too: the previous implementation was only
drawing the brush mask, which was absolutely not what would be expected for
such brushes.
- Add a white background behind color brushes with transparency.
- Simplify and clean up the code.
One of the consequences of this new implementation is obviously that it's
mandatory to call gegl_init() when using this widget.
… 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.
- Move the property widget functions for GimpResource properties into a new
libgimp/gimppropwidgets.[ch] file. This mirrors the files
libgimpwidgets/gimppropwidgets.[ch] which are for more generic property types.
- Rename the functions gimp_prop_chooser_*_new() to gimp_prop_*_chooser_new().
- gimp_prop_chooser_factory() doesn't need to be public.
- Add a label to GimpResourceSelectButton, make so that the
gimp_prop_chooser_*_new() functions set the property nick to this label and
add this label to the size group in GimpProcedureDialog.
- Removing useless or redundant code.
- Simplifying various logics.
- Using GimpResource directly in temporary PDB procedures, not resource names.
- Better cleanup of the core resource chooser when the plug-in dialog quits (we
need it to ask core to close also any visible resource chooser dialog).
- Replace the "Close" button by more common OK/Cancel. In particular, the
GimpPdbDialog now properly keeps track of the initial object and when hitting
"Cancel" (or Escape key), this initial object is set back.
- Clean up some of the comments, especially when the code is self explanatory.
There is still much more to clean and improve, but it's a first welcome step.
Found by the definitely useful libgimp warnings:
> gimp_plug_in_destroy_proxies: ERROR: GimpPattern proxy with ID 13 was refed by plug-in, it MUST NOT do that!
Brush, font, gradient, palette and pattern choices are currently chosen through
a dialog created by the core, which then returns the user choice to the calling
plug-in. This has the unfortunate consequence of having a pile of likely at
least 3 windows (main GIMP window by core process, plug-in window by plug-in
process, then the choice popup by the core process) shared in 2 processes, which
often end up under each other and that's messy. Even more as the choice popup is
kinda expected to be like a sub-part of the plug-in dialog.
So anyway, now the plug-in can send its window handle to the core so that the
resource choice dialog ends up always above the plug-in dialog.
Of course, it will always work only on platforms where we have working
inter-process transient support.
Instead of passing a guint32, pass the proper type, since our the HANDLE type
can be 64-bit on Windows (according to links I found).
I was hoping it might be the reason for the breakage under Windows, though I
also found Microsoft documentation saying that the 64-bit handle can be safely
truncated: https://learn.microsoft.com/en-us/windows/win32/winprog64/interprocess-communication?redirectedfrom=MSDN
Nevertheless I'd appreciate testing again from NikcDC or anyone else, as I
reactivated setting transient between processes on Windows.
Note that I also pass the proper types on X11 now (Window), even though guint32
worked fine. Better be thorough.
Having windows ID as guint32 is a mistake. Different systems have
different protocols. In Wayland in particular, Windows handles are
exchanged as strings. What this commit does is the following:
In core:
- get_window_id() virtual function in core GimpProgress is changed to
return a GBytes, as a generic "data" to represent a window differently
on different systems.
- All implementations of get_window_id() in various classes implementing
this interface are updated accordingly:
* GimpSubProgress
* GimpDisplay returns the handle of its shell.
* GimpDisplayShell now creates its window handle at construction with
libgimpwidget's gimp_widget_set_native_handle() and simply return
this handle every time it's requested.
* GimpFileDialog also creates its window handle at construction with
gimp_widget_set_native_handle().
- gimp_window_set_transient_for() in core is changed to take a
GimpProgress as argument (instead of a guint32 ID), requests and
process the ID itself, according to the running platform. In
particular, the following were improved:
* Unlike old code, it will work even if the window is not visible yet.
In such a case, the function simply adds a signal handler to set
transient at mapping. It makes it easier to use it at construction
in a reliable way.
* It now works for Wayland too, additionally to X11.
- GimpPdbProgress now exchanges a GBytes too with the command
GIMP_PROGRESS_COMMAND_GET_WINDOW.
- display_get_window_id() in gimp-gui.h also returns a GBytes now.
PDB/libgimp:
- gimp_display_get_window_handle() and gimp_progress_get_window_handle()
now return a GBytes to represent a window handle in an opaque way
(depending on the running platform).
In libgimp:
- GimpProgress's get_window() virtual function changed to return a
GBytes and renamed get_window_handle().
- In particular GimpProgressBar is the only implementation of
get_window_handle(). It creates its handle at object construction with
libgimpwidget's gimp_widget_set_native_handle() and the virtual
method's implementation simply returns the GBytes.
In libgimpUi:
- gimp_ui_get_display_window() and gimp_ui_get_progress_window() were
removed. We should not assume anymore that it is possible to create a
GdkWindow to be used. For instance this is not possible with Wayland
which has its own way to set a window transient with a string handle.
- gimp_window_set_transient_for_display() and
gimp_window_set_transient() now use an internal implementation similar
to core gimp_window_set_transient_for(), with the same improvements
(works even at construction when the window is not visible yet + works
for Wayland too).
In libgimpwidgets:
- New gimp_widget_set_native_handle() is a helper function used both in
core and libgimp* libraries for widgets which we want to be usable as
possible parents. It takes care of getting the relevant window handle
(depending on the running platform) and stores it in a given pointer,
either immediately or after a callback once the widget is mapped. So
it can be used at construction. Also it sets a handle for X11 or
Wayland.
In plug-ins:
- Screenshot uses the new gimp_progress_get_window_handle() directly now
in its X11 code path and creates out of it a GdkWindows itself with
gdk_x11_window_foreign_new_for_display().
Our inter-process transient implementation only worked for X11, and with
this commit, it works for Wayland too.
There is code for Windows but it is currently disabled as it apparently
hangs (there is a comment in-code which links to this old report:
https://bugzilla.gnome.org/show_bug.cgi?id=359538). NikcDC tested
yesterday with re-enabling the code and said they experienced a freeze.
;-(
Finally there is no infrastructure yet to make this work on macOS and
apparently there is no implementation of window handle in GDK for macOS
that I could find. I'm not sure if macOS doesn't have this concept of
setting transient on another processus's window or GDK is simply lacking
the implementation.
… is set.
The order for thumbnail creation in gimp_imagefile_create_thumbnail() is now:
1. If there is a GimpThumbnailProcedure, it is run first.
2. Otherwise we check if a thumbnail is in the metadata.
3. As last resort, we just load the full image.
Part of the fix was to copy gimp_image_metadata_load_thumbnail() into the core
code. I have been wondering if we could not drop the same function from libgimp
and remove the GimpThumbnailProcedure frome file-jpeg, since it just uses the
metadata thumbnail and it is the only plug-in using this code.
Also it is much faster to run this in core and it's generic function which makes
thumbnail loading from Exif data working for every format supported by Exiv2.
On the other hand, the file-jpeg thumbnail procedure also gathers a few more
useful information, such as the color model (in a reliably manner, since based
on JPEG header, unlike from metadata which may be wrong).
The various information (width, height, image type and number of layers) are
those of the full image, not of the thumbnail. Make it clear in the docs of
GimpRunThumbnailFunc.
Additionally:
- file-xmc was returning the proper information but variables were wrongly
named, which was confusing.
- Fix file-ico thumbnail proc which was returning the thumbnail width/height.
- In file-darktable, initialize width/height to 0 so that we just don't show any
size when we don't get the information. It's better not to show anything than
completely wrong information (the thumbnail target size).
… than a GimpValueArray.
Similar to other GimpProcedure, move to using a config object. A difference is
that thumbnail procedures are always run non-interactively.
Also fixing WMF load thumbnail procedure: the dimension computation was wrong
when the image was wider than tall.
… a GimpProcedureConfig for arguments.
This also factorizes the code to load metadata. By default, a GimpLoadProcedure
will try and load metadata from a file (if Exiv2 knows the format). The run()
function will be allowed to edit the GimpMetadata object but also the load flags
before it is actually attached to the image, allowing plug-ins to have custom
metadata handling code when needed.
This is just a method to simplify transforming a GimpChoice argument into an
enum value, which is easier to deal with, in C. It also allows to benefit from
switch() warnings or the like to make sure no cases are missing.
Developers won't have to maintain manually a list of the possible values in the
help string. It can now be generated from the GimpChoice and will be therefore
ensured to always be up-to-date, and nicely formatted.
I also add some pango markup to the type helper texts to differentiate it from
the main argument docs.
These will replace the int arguments used in place of enums. The problem of int
arguments used as list of choices is that it makes calling PDB functions very
opaque. This is especially bad when a list is long, so you constantly have to
refer to the documentation to understand what a series of numbers mean in
argument lists.
And the second issue is that plug-in developers have to manually maintain a list
of values both in the GUI and in the documentation string. This help text may
get out-of-sync, may end up with missing values or whatnot. Also if it is used
as tooltips, it makes for very weird tooltips in the graphical interface, with
an overlong technical list of int-values mapping which should ideally only be
made visible in the PDB procedure browser listing.
Now gimp_procedure_dialog_get_label() can work both with an existing property ID
or a new property ID. In the former case, it will simply sync the label with the
procedure argument, which will make it easy to update the label contents. In the
latter case, it just initialize with the provided text.
The expectation of 2 references per object in gimp_plug_in_destroy_proxies() was
wrong. It is true during most of the plug-in life, because both the
GimpProcedure and the GimpPlugIn have a hash-table keeping their own reference
to it, except that in gimp_plug_in_pop_procedure(), we release the reference
owned by the procedure with _gimp_procedure_destroy_proxies() first. So at this
point of the object life, its reference count is supposed to be 1.
The source of the bug was in fact in _gimp_plug_in_get_*() (where * can be
display, image, item or resource) which was behaving differently the first time
it is called for an object with the successive calls. In the first call only, it
was creating then refing into the table (so the object started directly with 2
references) whereas on successive calls, it just returned the hashtable-looked
up reference. In other words, it behaved as a (transfer full) on the first call
and (transfer none) on successive calls. And so did all public API which were
making use of this infrastructure (in particular gimp_*_get_by_id() functions).
The widget_creator_func() given to gimp_prop_chooser_factory() will create an
object which will take its own reference. We must release the one we got with
g_object_get().
Metadata handling is also integrated in this API:
* while giving a possibility to disable metadata saving if you want to do it
yourself (e.g. in file-heif), by setting a NULL MimeType;
* and the GimpMetadata object is added as run() argument, allowing one to edit
the metadata during the run, while still letting the infrastucture handle the
save (e.g. in file-jpeg);
* or to save intermediate metadata with gimp_procedure_config_save_metadata()
(e.g. in file-tiff).
While we definitely should not use this inside app/, because having the private
structure easily accessible as a member is very convenient, it is clear that it
makes for a much nicer public signature. Also the priv member is of no help to
third-party developers using this API to make plug-ins and is better hidden in
such a case.
This will be useful for plug-in developers but also for us. Seeing we leak the
config object is often a good indication that something is wrong in our handling
of internal references (since everything relies on the config object in plug-ins
now, in particular all the GUI).
I was clearly confused when I wrote this. The sinking part matters to take
ownership of a reference in the widgets table, but we don't need to ref widgets
again before inserting them in containers. We were leaking widgets and as a
consequence the config object (and as a second consequence, some objects such as
resources for resource-selection widgets).
Same as with gimp_procedure_new2(), I will end up renaming the function to
gimp_image_procedure_new() once all usage of this function will have been ported
to the new function using GimpProcedureConfig instead of GimpValueArray
arguments.
The one in GimpResourceSelect is a very nice example of why using config objects
is much nicer, getting arguments by their name instead of an index (which in
this case had to be tracked down by a private function to handle different
cases).
Also in gimp_procedure_config_begin_run(), make sure we sync the arguments with
the config object first thing, even in interactive and with-last-vals case
(where the args may be further overridden). This was especially important for
Script-fu scripts as the image and drawable were not provided separately, so we
need to make sure that the config file has the right values.
Otherwise we will always try to reuse previous values or use the default,
bypassing the actual passed values.
I encountered this issue while porting file-glob and realizing that the
"pattern" argument was always passed to NULL, ignoring the explicitly set
pattern.
When a procedure has no run-mode argument, we should simply not assume anything
and use the passed arguments (which is what the non-interactive mode does).
This function allows to change the sensitivity of a widget depending on the
value of another property.
We already had gimp_procedure_dialog_set_sensitive() except it was only syncing
with a boolean property, whereas the new function can compare with any property
type.
This new function is meant to replace gimp_procedure_new() when all plug-in
usage will have been switched.
This function creates the GimpProcedureConfig object on behalf of the plug-in
and calls gimp_procedure_config_begin_run() and gimp_procedure_config_end_run().
This way we ensure that all plug-in calls with successful result are properly
stored without asking the developer not to forget to call these (if a "good
practice" is in fact something we request to do every time, especially for good
user experience, we might as well make it rather a core process).
Advantages:
* Better interactive experience: using any plug-in will result in saved
previously used settings.
* for developers, working on config objects is also much more comfortable than
working on GValueArray;
* step forward for the future macro infrastructure: if we can ensure that all
plug-in calls are properly logged, then we can replay plug-in actions, in
NON_INTERACTIVE with the same settings.

I get a critical error when calling gimp_text_layer_new and the function
doesn't return a GimpTextLayer:
(file-psd:47120): LibGimp-CRITICAL **: 16:00:59.035:
gimp_gp_param_to_value: type name GimpTextLayer is not registered
Adding the above line to libgimp/gimp.c fixes the problem.
Looking further, the @help is only used in gimp_proc_view_new() so far (for the
Procedure Browser) where the blurb and argument descriptions are already
localized. It makes no sense to only keep this in English. So let's ask to have
both arguments translated.
Now clearly we should not ask for @help to be mandatory. Very often, it makes no
sense to have a longer help string (the small blurb and the few arguments may be
very self-explanatory). So I make this argument nullable.
There is only the @help_id which I wonder if we could not have a simpler
function gimp_procedure_set_documentation_uri(). Indeed while having a unified
infrastructure with a XML summary and help IDs and whatelse makes sense for GIMP
as a whole, I think that many third-party plug-ins would work much better with a
very simple direct URL. Or it could even be a GFile to a local file (for
plug-ins which want to embed their documentation in the plug-in folder for
instance). To be continued…
I add a new class method deserialize_create() to GimpConfigInterface which
returns the GimpConfig object per deserialization, instead of modifying an
existing bare object.
This matters for cases like our GimpResource (and later our GimpItem) classes
which are fully managed by libgimp and should be unique objects per actual
resource. It should even be possible to compare the pointer itself for identity.
That's why we need to let GimpResource create the object (in reality request it
to the infra and only ref it) through this new class method.
With this commit and the previous ones, all GimpResource are now properly stored
as plug-in settings (e.g. the "film" plug-in has a font setting which is now
properly remembered).
These identifiers are not portable (across various installations and therefore
not for XCF either), but at least they are reasonably identifying data on a same
installation (unlike GimpResource's int ID which is only valid within a single
session) which makes them very fine for plug-in settings storage.
When a data file disappears, we fallback to the context default data instead.
This finds the core resource knowing its type, name, collection and internal
state (in other words, the values returned by _gimp_resource_get_identifiers()).
Rather than reimplementing the same checks for every possible resource data
type, just do it once and redirect to the correct factory container.
For the libgimp API, we leave per-type functions `gimp_*_get_by_name()` (where *
can be brush|gradient|font|palette|pattern so far), but internally they all use
gimp_pdb_get_resource().
Note that eventually we want these functions to return a list of resources as it
should be possible to have several resources of a given type with the same name
(since they are made by third-party who might have had the same idea of a name).
We use US English which uses behavior. So we replace all occurrences of
behaviour.
Most notable is File Open behavior in preferences. Besides that several
mentions in function documentation and a few in comments.
Resources are stored by the plug-in infrastructure and their memory should not
be managed by plug-in code.
My commit 4f69995b46 was crappy and modified a generated function. I was just
too tired with all the heat in here, I guess!
Similarly to how we handled image items, all resources are handled and stored by
the plug-in infrastructure and should not be destroyed. This wrong annotation
was triggering bindings to unref resources when going out of scope, hence
crashing plug-ins.
Since commit 89c359ce47, it's supposed to return a GBytes, yet it was returning
raw data (probably intermediate hacking state which was not properly cleaned
up).
It was crashing for instance GimpDrawablePreview widgets at drawing time.
It does absolutely nothing except sitting there, providing an is-a
relation (both ways because GimpData is its only subclass). This will
simplify having more libgimp API on GimpResource, without having to
add different PDB code for app and libgimp.
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
and Plug-in/Procedure Browser size.
gtk_widget_set_size_request () is applied to the dialog, as it does not
seem to bubble up from being applied to individual elements.
The existing 2.10 width/height values are used.
GLib has a specific type for byte arrays: `GBytes` (and it's underlying
GType `G_TYPE_BYTES`).
By using this type, we can avoid having a `GimpUint8Array` which is a
bit cumbersome to use for both the C API, as well as bindings. By using
`GBytes`, we allow other languages to pass on byte arrays 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 byte arrays
in other C/GLib based code (and not having 2 different types to denote
the same thing).
