Also fixes the passing of the resource param definitions through PDB.
There was some weird assumption, with a comment, in commit 73733335c8
that this was unneeded, which meant that we were not able to properly
recreate the right param spec over the wire.
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).
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!
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.
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().
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.
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.
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).

Since we changed it, the version must be incremented too. It means that
third-party developers will have to rebuild their plug-ins.

`GStrv`, we allow other languages to pass on string lists as they are

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.
Which means support for GParamSpecObject with value_type ==
G_TYPE_FILE, and converting between GFile and its URI for wire
communication directly above the protocol layer.
This change requires passing a GParamSpec's value type as generic
member of GPParamDef, which in turn makes some members of its
sub-structures obsolete.
It's just too weird to be public. Remove its properties from the wire
protocol and from pluginrc. Instead, have all GParamSpecs' flags on
the wire and in pluginrc, so we can use stuff like
GIMP_PARAM_NO_VALIDATE.
Port the remaining few places to GIMP_PROC_ARG_STRING().
I'm sure something is broken now wrt UTF-8 validation,
will add tighter checks in the next commit.
Pass the help-id specified by the procedure to the core, and use it in
the core if set instead of always using the procedure's name (which
was probably good enough for all eternity, but it's still more
consistent this way).
- libgimpbase: change GPParam to transfer all information about the
GValues we use, in the same way done for GPParamDef. GPParam is now
different from GimpParam from libgimp, pointers can't be casted any
longer. The protocol is now completely GimpPDBArgType-free. Remove
gp_params_destroy() from the public API.
- libgimp: add API to convert between an array of GPParams and
GimpValueArray, the latter is now the new official API for dealing
with procedure arguments and return values, GimpParam is cruft (the
wire now talks with GimpPlugIn more directly than with the members
of GimpPlugInInfo, which need additional compat conversions).
- libgimp, app: rename gimpgpparamspecs.[ch] to simply
gimpgpparams.[ch] which is also more accurate because they now
contain GValue functions too. The code that used to live in
app/plug-in/plug-in-params.h is now completely in libgimp.
- app: contains no protocol compat code any longer, the only place
that uses GimpPDBArgType is the PDB query procedure implementation,
which also needs to change.
- app: change some forgotten int32 run-modes to enums.
- Change the wire protocol's GPProcInstall to transmit the entire
information needed for constructing all GParamSpecs we use, don't
use GimpPDBArgType in GPProcInstall but an enum private to the wire
protocol plus the GParamSpec's GType name. Bump the wire protocol
version.
- Add gimpgpparamspecs.[ch] in both app/plug-in/ and libgimp/ which
take care of converting between GPParamDef and GParamSpec. They
share code as far as possible.
- Change pluginrc writing and parsing to re-use GPParamDef and the
utility functions from gimpgpparamspecs.
- Remove gimp_pdb_compat_param_spec() from app/pdb/gimp-pdb-compat.[ch],
the entire core uses proper GParamSpecs from the wire protocol now,
the whole file will follow down the drain once we use a GValue
representation on the wire too.
- In gimp_plug_in_handle_proc_install(), change the "run-mode"
parameter to a GParamSpecEnum(GIMP_TYPE_RUN_MODE) (if it is not
already an enum). and change all places in app/ to treat it as an
enum value.
- plug-ins: fix cml-explorer to register correctly, a typo in
"run-mode" was never noticed until now.
- Add gimpgpcompat.[ch] in libgimp to deal with all the transforms
between old-style wire communication and using GParamSpec and
GValue, it contains some functions that are subject to change or
even removal in the next steps.
- Change the libgimp GimpProcedure and GimpPlugIn in many ways to be
able to actually install procedures the new way.
- plug-ins: change goat-exercise to completely use the new GimpPlugIn
and GimpProcedure API, look here to see how plug-ins will look in
the future, of course subject to change until this is finished.
- Next: changing GPParam to transmit all information about a GValue.
Pass the GEGL tile-cache size, swap path, and thread-count to plug-
ins as part of their config, and have libgimp set the plug-in's
GeglConfig accordingly upon initialization.
Registering a full menu path as a procedure's menu label is now
forbidden and causes the procedure to be rejected.
Bump the plug-in protocol version so a pluginrc containing such cruft
is not used.
...upon exporting an image
Step 1: make it configurable just like "Export EXIF" etc.
app, libgimp: add "export-color-profile" config option
Add it to the preferences dialog, and pass it on to plug-ins in the
GPConfig message. Add gimp_export_color_profile() to libgimp.
Nothing uses this yet.
Also remove all traces of it from the plug-in protocol and raise the
protocol version to 0x0100 (we now allow features and therefore
version bumps in stable, and the master protocol version should always
be higher). Fix the code that aborts plug-in startup on protocol
version mismatch, we can't use gimp_message() because we have no
protocol.
Pass the current icon theme directory to plug-ins through the
config message, and add a gimp_icon_theme_dir() libgimp function
for retrieving it. Note that we already have a similar
gimp_icon_get_theme_dir() PDB function, which we keep around, since
it can be used to dynamically query for the current icon dir,
unlike the former, and since it returns a dynamically-allocated
string, while the rest of the config-related functions return
statically allocated strings.
Use the new function, instead of gimp_get_icon_theme_dir(), in
gimp_ui_init(). This allows gimp_ui_init() to run without making
any PDB calls. Consequently, this allows us to start plug-ins that
call gimp_ui_init() without entering the main loop in the main app.
We're going to add a plug-in that displays an interactive dialog
while the main app is blocking waiting for an operation to
complete, and we need to be able to start the plug-in without
entering the main loop, to avoid the possibility of arbitrary code
being executed during the wait.
Bump the protocol version.
...protocol calls.
Some calls are waiting for answers, for instance plugin procedures, and
tiles which expects data and acknoledgement.
This would result in error messages such as:
"expected tile ack and received: 5" (5 is GP_PROC_RUN)
Typically because a thread would run a procedure while another would
receive tiles.
The item groups has all the duplicated functionality from drawable
and vectors (name, visible, linked etc).
Hijack the unused GIMP_PDB_REGION and turn it into GIMP_PDB_ITEM;
change all protocol aware files accordingly and bump the protocol
version number. Change script-fu to handle the new type.
