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.
Just as documented, pixel unit should always return factor 0. There is
no need to call _gimp_unit_vtable.unit_get_factor().
This is even more important as there is one implementation of
unit_get_factor() in core, and another in libgimp and the one in libgimp
is expecting unit to always be >= GIMP_UNIT_INCH. So we were getting
CRITICALs in libgimp when calling gimp_unit_get_factor() on pixel unit
(for instance when drawing a GimpRuler).
because they are deprecated.
Change GIMP_ICON_TYPE_INLINE_PIXBUF to GIMP_ICON_TYPE_PIXBUF and the
libgimp API to (icon-name, GdkPixbuf, GFile). Use the file's uri and a
PNG blob of the pixbuf to pass around on the wire and for storage in
pluginrc.
libgimp is anyway processed at the very end after all other libgimp*
were built. This way, it also fixes#3746, by removing the $(top_srcdir)
everywhere from introspected files, hence making the build work again
with older automake.
So a value array can now we created like this:
array = gimp_value_array_new_from_types (&error_msg,
G_TYPE_STRING, "foo",
G_TYPE_INT, 23,
G_TYPE_NONE);
Change PDB generation to use this, which makes for much nicer code in
the libgimp wrappers, and only set arrays separately instead of all
values.
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).
This partly reverts commit d999248d70.
The GimpStringArray is still very weirdly handled, in particular
regarding the difference of processing with static_data set or not.
Still this g_return_val_if_fail() was making more problems. It may come
back but will need more coding to handle the side effects.
Our GimpStringArray is so weird. We are obviously expecting it to be
NULL-terminated since, when we duplicate the data, we add one value.
Yet we were not checking that the stored data was NULL-terminated, in
particular when the string array is created with static data (in which
case, we use the input data as-is, without re-allocating).
Note that this doesn't fix the type mismatch Gimp.StringArray vs
Gimp.Array when introspecting.
Documentation-wise in C, this doesn't matter a lot, but it allows
GObject-Introspection based bindings to use their built-in versions when
they want to render any kind of documentation (for example, docs for
Python plugins can render `%NULL` as `None`).
Basically the number of parameters comes from plug-ins which could write
whatever crap on the wire. I had a case (playing with Python plug-ins)
where GIMP tried to allocate insane amount of parameters. This is bad
as it allows third-party plug-ins to crash GIMP core.
Instead only *try* to allocate, then return as though there were no
parameters if allocation fails. I also print some info on stderr, but
don't output WARNING/CRITICAL (this is not a core error, but a plug-in
error). Fixes:
> GLib-ERROR **: 16:30:23.357: gmem.c:135: failed to allocate 187186442160 bytes
which means that it's now included normally via gimpbase.h
and not any longer via gimpbasetypes.h which we only did out
of lazyness. A *lot* of files in libgimp* and app/ now need to
and _new_from_types_valist()
which take a va_list of GTypes and creates a GimpValueArray
initialized with these types, so one can simply have a list of
g_value_set_foo (gimp_value_array_index (array, i), foo);
in the next lines. I'm not so sure this is the best API ever...
- 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.
all the stuff from app/core/gimpparamspecs.[ch] that is not about
image, drawable etc IDs, these will have to go to libgimp with
different implementations than in app/.
At first I thought these could be different namespaces, but actually
GObject Introspection parses files and can only use (AFAICS) the
namespace actually used in our C function, which is always `gimp_` (and
not `gimpbase_` or whatever.
So make the introspection at the root level, and it will include all
libgimp* libraries in one namespace, same as the C lib anyway. For now
only libgimp and libgimpbase as I am still testing.
Also I move the introspectable sources in their own file in order to
share the list between the library building Makefile and the GI
makefile because I can't find how to pass over variables otherwise.
So far only libgimpbase is introspected. It just works though (I could
test that I could just run a plug-in which could access libgimpbase API
without any problem).
The g-ir-scanner call outputs a lot of warning but I won't care for
these right now.
The `introspection.m4` is taken straight from GEGL tree.
Add a new gimp:offset operation, which implements equivalent
functionality to gimp_drawable_offset(), in preparation for adding
an interactive offset tool.
To simplify things, add a GIMP_OFFSET_WRAP_AROUND value to the
GimpOffsetType enum, to avoid the need for a separate wrap-around
flag. This makes the gimp-drawable-offset procedure parameters a
little superfluous, but whatever.
Older --enable-binreloc configure option had basically the same purpose
as the newer --enable-relocatable-bundle, though the old binreloc was
only used for gimpenv.c code.
As a consequence, commit 10ce702188 was still not working fine since
gimp_installation_directory_file() also need binreloc enabled (to be
actually relocatable).
Let's get rid of this whole mess, by implying we want binreloc code to
be used when --enable-relocatable-bundle is ON. We don't need the
m4macros anymore, since AM_BINRELOC was basically just checking that
`/proc/self/maps` was present. But anyway being present at compile time
does not mean it will be at runtime (nor the opposite). So this test is
not that useful. The binreloc code will anyway fallback gracefully to
the non-binreloc code (i.e. trying to use build-time install paths) if
the procfs is lacking at runtime.
... on macOS.
The debugger running on macOS is usually lldb and (from the reports we
get) it looks like lldb displays the tid as hexadecimal on macOS
(whereas lldb displays decimal tid on Linux! I know, it's confusing, yet
consistent with crash report experience!). So let's just do the same,
making it easy to quickly copy-search in order to look up the crashing
thread (without having to convert from decimal to hexa).
This is a bit of an approximation as I imagine we could have gdb on
macOS or whatever edge case. Let's say it's good for the common case and
still not an error otherwise (just a base conversion away).
gimp_metadata_add() which is used to set blobs or EXIF, XMP and IPTC
on a GimpMetadata also needs the logic to set "multiple" tags in one
go, or it will lose all but the first one.
We were not taking into account tags that can appear multiple times,
such as "keyword", they are handled by gexiv2 with the
get_tag_multiple() and set_tag_multiple() functions.
gimp_metadata_deserialize_text(): when deserializing our XML format,
check if a tag is already set on the metadata as "multiple" and if yes
retrieve it, append the new value and set it again.
gimp_image_metadata_save_finish(): take care of "multiple" values when
copying tags to new metadata created for saving.
This should preserve all values across an "import, edit, export".
Thing will still break when using the metadata editor, it doesn't
handle multiple values at all, but that code is very hard to
understand.
The whole bucket fill specific enum stuff is on its way out, so let's
keep this one out of libgimp for now until we decide how to present
line art filling in the PDB.
This was my initial choice, but the more I think about it, the less I am
sure this was the right choice. There was some common code (as I was
making a common composite bucket fill once the line art was generated),
but there is also a lot of different code and the functions were filled
of exception when we were doing a line art fill. Also though there is a
bit of color works (the way we decide whether a pixel is part of a
stroke or not, though currently this is basic grayscale threshold), this
is really not the same as other criterions. In particular this was made
obvious on the Select by Color tool where the line art criterion was
completely meaningless and would have had to be opted-out!
This commit split a bit the code. Instead of finding the line art in the
criterion list, I add a third choice to the "Fill whole selection"/"Fill
similar colors" radio. In turn I create a new GimpBucketFillArea type
with the 3 choices, and remove line art value from GimpSelectCriterion.
I am not fully happy yet of this code, as it creates a bit of duplicate
code, and I would appreciate to move some code away from gimpdrawable-*
and gimppickable-* files. This may happen later. I break the work in
pieces to not get too messy.
Also this removes access to the smart colorization from the API, but
that's probably ok as I prefer to not freeze options too early in the
process since API needs to be stable. Probably we should get a concept
of experimental API.
Add flag GIMP_METADATA_SAVE_COLOR_PROFILE to GimpMetadataSaveFlags and
initialize it from gimp_export_color_profile() in
gimp_image_metadata_save_prepare().
Adapt all plug-ins to use the bit from the suggested export flags and
pass the actually used value back to
gimp_image_metadata_save_finish().
This changes no behavior at all but creates hooks on the libgimp side
that are called with the context of an image before and after the
actual export, which might become useful later. Also, consistency
is good even though the color profile is not strictly "metadata".
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.
Move swap/cache and temporary files out the GIMP user config dir:
libgimpbase: add gimp_cache_directory() and gimp_temp_directory()
which return the new default values inside XDG_CACHE_HOME and the
system temp directory. Like all directories from gimpenv.[ch] the
values can be overridden by environment variables. Improve API docs
for all functions returning directories.
Add new config file substitutions ${gimp_cache_dir} and
${gimp_temp_dir}.
Document all the new stuff in the gimp and gimprc manpages.
app: default "swap-path" and "temp-path" to the new config file
substitutions. On startup and config changes, make sure that the swap
and temp directories actually exist.
In the preferences dialog, add reset buttons to all file path pages.
This commit implements part of the research paper "A Fast and Efficient
Semi-guided Algorithm for Flat Coloring Line-arts" from the GREYC (the
people from G'Mic). It is meant to select regions from drawn sketchs in
a "smart" way, in particular it tries to close non-perfectly closed
regions, which is a common headache for digital painters and colorists.
The implementation is not finished as it needs some watersheding as well
so that the selected area does not leave "holes" near stroke borders.
The research paper proposes a new watersheding algorithm, but I may not
have to implement it, as it is more focused on automatic colorization
with prepared spots (instead of bucket fill-type interaction).
This will be used in particular with the fuzzy select and bucket fill
tools.
Note that this first version is a bit slow once we get to big images,
but I hope to be able to optimize this.
Also no options from the algorithm are made available in the GUI yet.
... to make multi-color hard-edge gradient fills possible
Add a new "step" gradient-segment blending function, which is 0
before the midpoint, and 1 at, and after, the midpoint. This
creates a hard-edge transition between the two adjacent color stops
at the midpoint. Creating such a transition was already possible,
but required duplicating the same color at the opposing ends of two
adjacent stops, which is cumbersome.
It seems that calling `lldb` when it is absent triggers some popup
proposing to install Xcode on macOS. This is obviously not good. Let's
check presence with g_find_program_in_path() instead. I was refraining
from doing so until now, because this function allocates memory, hence
may not do well during a crash.
Fortunately we don't need to check for lldb during crash (unlike gdb
which has some unacceptable behavior for older versions, at least on
FreeBSD) so that should be ok.
This is my attempt to get better labels, shorter and also (hopefully)
improved English.
As Mitch states though, this is a Japanese-French-German conspiracy! So
any of you native English speakers out there, please review and suggest
proper English if needed. :-)

All babl formats now have a space equivalent to a color profile,
determining the format's primaries and TRCs. This commit makes GIMP
aware of this.
libgimp:
- enum GimpPrecision: rename GAMMA values to NON_LINEAR and keep GAMMA
as deprecated aliases, add PERCEPTUAL values so we now have LINEAR,
NON_LINEAR and PERCPTUAL for each encoding, matching the babl
encoding variants RGB, R'G'B' and R~G~B~.
- gimp_color_transform_can_gegl_copy() now returns TRUE if both
profiles can return a babl space, increasing the amount of fast babl
color conversions significantly.
- TODO: no solution yet for getting libgimp drawable proxy buffers in
the right format with space.
plug-ins:
- follow the GimpPrecision change.
- TODO: everything else unchanged and partly broken or sub-optimal,
like setting a new image's color profile too late.
app:
- add enum GimpTRCType { LINEAR, NON_LINEAR, PERCEPTUAL } as
replacement for all "linear" booleans.
- change gimp-babl functions to take babl spaces and GimpTRCType
parameters and support all sorts of new perceptual ~ formats.
- a lot of places changed in the early days of goat invasion didn't
take advantage of gimp-babl utility functions and constructed
formats manually. They all needed revisiting and many now use much
simpler code calling gimp-babl API.
- change gimp_babl_format_get_color_profile() to really extract a
newly allocated color profile from the format, and add
gimp_babl_get_builtin_color_profile() which does the same as
gimp_babl_format_get_color_profile() did before. Visited all callers
to decide whether they are looking for the format's actual profile,
or for one of the builtin profiles, simplifying code that only needs
builtin profiles.
- drawables have a new get_space_api(), get_linear() is now get_trc().
- images now have a "layer space" and an API to get it,
gimp_image_get_layer_format() returns formats in that space.
- an image's layer space is created from the image's color profile,
change gimpimage-color-profile to deal with that correctly
- change many babl_format() calls to babl_format_with_space() and take
the space from passed formats or drawables
- add function gimp_layer_fix_format_space() which replaces the
layer's buffer with one that has the image's layer format, but
doesn't change pixel values
- use gimp_layer_fix_format_space() to make sure layers loaded from
XCF and created by plug-ins have the right space when added to the
image, because it's impossible to always assign the right space upon
layer creation
- "assign color profile" and "discard color profile" now require use
of gimp_layer_fix_format_space() too because the profile is now
embedded in all formats via the space. Add
gimp_image_assign_color_profile() which does all that and call it
instead of a simple gimp_image_set_color_profile(), also from the
PDB set-color-profile functions, which are essentially "assign" and
"discard" calls.
- generally, make sure a new image's color profile is set before
adding layers to it, gimp_image_set_color_profile() is more than
before considered know-what-you-are-doing API.
- take special precaution in all places that call
gimp_drawable_convert_type(), we now must pass a new_profile from
all callers that convert layers within the same image (such as
image_convert_type, image_convert_precision), because the layer's
new space can't be determined from the image's layer format during
the call.
- change all "linear" properties to "trc", in all config objects like
for levels and curves, in the histogram, in the widgets. This results
in some GUI that now has three choices instead of two.
TODO: we might want to reduce that back to two later.
- keep "linear" boolean properties around as compat if needed for file
pasring, but always convert the parsed parsed boolean to
GimpTRCType.
- TODO: the image's "enable color management" switch is currently
broken, will fix that in another commit.
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.
In gimp_metadata_set_from_{exif,iptc,xmp}(), gracefully reject data
of invalid size, returning an error instead of raising a critical.
In particular, this avoids a CRITICAL when loading an XCF with an
empty exif-ata parasite.
The flag `free_selection_string` is used to track an array of strings
with some of them being static and others allocated. This should have
been an array of boolean but we can't change it because it is public API
(though it should really not have been!).
So let's just allocate every string of the `selection` array instead,
which makes the boolean flag useless now.
(cherry picked from commit b585201e5e)
... after each successful read().
I completely missed this declaration after a statement during the review
of !13 even though I saw another similar issue!
Also let's reset the error counter to 0 each time a successful read()
happens so that we can continue reading even if a lot of EINTR were to
happen, as long as we globally go forward. Only consecutive errors
increment the counter.
Finally add a small comment to explain why we let EINTR pass instead of
breaking directly.
When lldb attaching to the process it triggers few "-1" errors on read with
EINTR error. After 1-2 errors read() call works again.
Also this patch fixing TID detection, syscall SYS_gettid is oficially deprecated
now and does not work. Also adding safecheck to avoid enldless loop.
...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.
even if we don't have private members (yet). Also make class padding 8
pointers in all headers. This commit moves nothing to private, it just
makes all headers consistent and adjusts .c files accordigly.
Let's make our various usages of this broken function more robust, or at
least return with errors when we can. But this is still seriously
broken. Inside gimp_locale_directory() though, there was nothing I could
do, so I just added a FIXME for at least keeping an eye on it.
I could not find for sure what to use on FreeBSD instead, so let's just
not get this information there. It is quite useful information to know
where thread traces were asked from, but it is more important to make
sure the program can be compiled everywhere. Also we can just check
which thread has gimp_stack_trace*() calls. Thus it can be seen as
redundant information in any case.
SYS_gettid is apparently defined as a macro, so let's simply check for
it being defined.
First WIP commit, adds:
- enum GimpGradientBlendColorSpace { RGB_PERCEPTUAL, RGB_LINEAR }
- linear blending mode for gradient segments
- tool options GUI for the blend and paint tools which use gradients
Since commit bb52431cdd, we get multi-thread traces in functions
gimp_stack_trace_*(). Adding now the LLDB equivalent improvement.
Also adding the process and thread id information, from which the trace
order was made, atop the listing, as well as the thread list. This would
allow to easily find and associate the threads.
The problem is that sometimes the thread where we got a trace from may
not matter (for instance signals, even such as SIGABRT or SIGSEGV, seem
to sent a bit randomly to either the thread which provoked them or the
main thread; there is a bit of contradictory info on this when reading
on the topic, in my case I experienced this), in such case, getting all
thread stack is important to find the origin of the signal.
Other times it will highly matter, in particular when getting a trace
for a WARNING or CRITICAL. This information will help to discriminate
between thread traces.
Last commit caused -xobjective-c to be passed during linking on
Mac, causing object files to be treated as source files. Add a
-xnone flag to AM_LDFLAGS, canceling the effect of -xobjective-c.
Additinally, add a -xobjective-c++ flag to AM_CXXFLAGS, so that we
can use Objective-C in C++ files on Mac, if we ever need to.
On Mac, pass -xobjective-c to the compiler through AM_CFLAGS, not
AM_CPPFLAGS, so that it's only used for C sources, and not C++
sources. In the latter case, it clashes with the -std=... flag,
spewing an error. Thanks, Partha :)
... non-latin unicode path.
g_win32_locale_filename_from_utf8() was sometimes returning NULL for
some paths on Windows. Then the call to gexiv2_metadata_open_path() with
a NULL value was crashing plug-ins.
This commit only prevents from crashing by simply failing to load
metadata when this occurs, which means losing metadata support on
Windows depending on filenames. A proper solution will have to be
implemented.
It seems old blend tool (from GIMP 2.8) was using manhattan distance,
whereas the new one uses euclidean. I guess there must be use cases for
both. In any case, it is a good idea to simply propose the option since
the property exists in the "gegl:distance-transform" operation.
See also bug 781621.
Reap the child *after* we're done reading its output, so that we
can disable ptracing after reading, but before reaping. This
avoids a window during which the child is gone, but ptracing using
its PID is still allowed.
Clear the ptrace permission given to the child after it terminates,
so that a future process that happens to have the same PID the
child had can't ptrace us.
On Linux, when /proc/sys/kernel/yama/ptrace_scope is 1, a process
may only ptrace its descendants by default, which prevents the GDB
process spawned by gimp_stack_trace_print() from attaching to, and
producing a backtrace for, the calling process.
Use prctl() with PR_SET_PTRACER, when available, in the parent
process, to allow the child process to ptrace it.
It seems that older GDB (under version 7) are not handling very well
some common debug information format, in particular DWARF > 3. Such
version of GDB is usually not a problem since it is quite old (more than
10 years old, it would seem) so you don't see it anymore on any modern
GNU/Linux distribution. On FreeBSD on the other hand, it is still
available (probably for license reasons) and even installed by default!
As a consequence, it makes debugging fail, even though LLDB is also
installed by default.
That is even more of a problem because it would seem that GIMP is killed
(most likely by FreeBSD kernel according to the reporter tests) as a
side-effect of GDB failing, which is seriously bad, in particular since
we also use the debug dialog for non-fatal errors (which could therefore
end up killing GIMP as side effect of a bad GDB!).
So I add some GDB version check. I implement this without any dynamic
memory management, as usual, since this needs to happen also during
crash handling where the state is unstable and prone to memory
allocation failure.
I also add gimp_utils_backtrace_available() public API which can be used
by the Preferences.
The only debugger command which uses this value currently is gdb. And
even there, it doesn't look mandatory. The alternative call using "-p"
option does not require the program name. The manual doesn't say if
calling with the program name has any advantage (but I don't see why it
would, the PID is enough to find a process). Just in case, I leave the
prog_name parameter (because it's easier to make a parameter useless
than changing a libgimp* API) but simply allows setting it to NULL.
... backtrace_symbols() when possible.
When we allocate a new string, anyway we have memory allocation. But
when we just print to a file descriptor, this version of the API is
guaranteed without any memory allocation and therefore should always
work. This is important since allocations may fail in particular after
memory errors.
The value descriptions of GimpGradientColor,
GimpGradientSegmentColor, and GimpGradientSegmentType enums appear
in the on-canvas gradient editor UI, as combo-box items in the tool
GUI overlay. Since we want to keep the overlay as small as
possible, we previously used abbreviations for these descriptions
(e.g., "FG (t)", instead of "Foreground (transparent)").
Replace the abbreviated descriptions with unabbreviated ones, and
move the abbreviations to the "abbrev" parameter. This way we get
the abbreviated version in the combo-box, and the full version in
the combo-box's menu.
Update the dprod production of generated enum files to include
abbreviated value descriptions, as per the previous commits.
Add a comment for translators above the abbreviated descriptions,
specifying the full description they abbreviate.
Add support for specifying an abbreviated description for enum/
flags values, which can be used in contexts where the full
description is too long.
Since the exact layout and size of Gimp{Enum,Flags}Desc is part of
the ABI, we can't simply add a field to these structs to hold the
abbreviated description. Instead, we use the fact that entries
with a repeated value in the value descriptions array are ignored,
and that the array is NULL terminated (in particular, that all non-
NULL entries are followed by at least one additional entry), and
specify the abbreviation in the "value_desc" field of the entry
that immediately follows the initial entry for a given value,
setting the "value" field of both entries to the same value.
Right now this behavior is undocumented, so there is no proper way
to specify abbreviated descriptions in the API, and is only meant
to be used in generated enum files.
to gimp_base_compat_enums_init() and move its prototype from
gimputils.h to gimpbase-private.h; it's not supposed to be
public API even though it's callable from the outside.
Allows setting the midpoint's position, blending function, and
coloring type.
The midpoint can be converted to a stop, and centered, through
editor buttons.
...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.
...on macOS (with macports)
Changed gimp_metadata_get_guid() to use a GRand that automatically
seeds itself from /dev/urandom (if available) or the current time.
...resources to be loaded and shown multiple times
Change gimp_path_parse() to filter out duplicate paths. This is the
function at the bottom which is used by everything else, so should
generically catch all duplicates.
Commit 1e6acbd4e1 modified the
generated enum recipes to run gimp-mkenums from the source
directory, instead of the build directory, so that only the
basenames of the corresponding header files would appear in
the comment at the top of the generated files. This was a
mistake -- $(GIMP_MKENUMS) is expecting to be invoked from the
build directory.
Switch back to running gimp-mkenums from the build directory. To
avoid including the relative path from the build directory to the
source directory in the generated file, add a @basename@ production
variable to gimp-mkenums, which exapnds to the basename of the
input file, and use it instead of @filename@ in the recipes for the
generated enum files.
When regenerating an enum file, don't copy it back to the source
directory if it hasn't actually changed. This allows using a read-
only source directory where the enum header is newer than the
generated file, as long as they're not really out of sync.
OTOH, *do* touch the generated source-dir file even when unchanged,
in order to avoid re-running its recipe on the next build, however,
allow this to silently fail (which is harmless).
Add the additional enum values to enum GimpSelectCriterion, and
the few needed lines to gimppickable-contiguous-region.c.
It's horribly slow, but works.
We check them into git, so this makes it easier to keep them in
sync when using a separate build directory.
Case in point -- this commit also syncs a few enum files that went
out-of-sync with their headers.
It was agreed that we should write "plug-in" consistently. Only possibly
user-visible strings were updated.
Thanks to scootergrisen for a first patch which could not make it
after changing decision on the canonical writing.
which unlike HSL Lightness is actually physically meaningful and
also generally speaking much more useful than HSL Lightness.
Change "Lightness" to "Lightness (HSL)" to make it clear that
the "Lightness" in the Colors/Desaturate/Desaturate menu is not the
same as "Lightness" in LAB/LCH.
For completeness add the option to desaturate to "Value (HSV)".
Add links in app/operations/gimpoperationdesaturate.c
to the Wikipedia article with definitions of L/I/V in HSL/HSI/HSV.
being exported to libgimp, and having a non-exported value, this is a
horrible mess like with GimpLayerMode, but at least the cruft value
names are deprecated now.
C++ won't allow us to use GimpLayerMode in the API where we used to
have GimpLayerModeEffects.
Move GimpLayerModeEffects to libgimpbase/gimpcompatenums.h so it's
not in the API any longer, and instead typedef and define stuff in
libgimp/gimptypes.h, and adapt the compat enum registering code
accordingly.
Which are entirely private (not installed). They contain compat values
for enums where values have been renamed in gimpbaseenums.h. The old
names get the old nicks generated so the new values in gimpbaseenums.h
can have proper new nicks. Register them as compat enums using
mechanism introduced for the GimpLayerMode change.
with proper value names. Mark most values as _BROKEN because they use
weird alpha compositing that has to die. Move GimpLayerModeEffects to
libgimpbase, deprecate it, and set it as compat enum for GimpLayerMode.
Add the GimpLayerModeEffects values as compat constants to script-fu
and pygimp.
Add property "color-tag" of type enum GimpColorTag to GimpItem so all
layers, channels and paths can be tagged with a color.
For interoperability, use the color list from Krita which is a
superset of Photoshop's colors.
Features a "Color Tag" submenu in the layers, channels and paths
menus, a row of color radio buttons in the properties dialogs,
undo and PDB API.
As a side effect, some common code is now factores out into
items-actions.[ch] and items-commands.[ch] which adds visible, linked
and lock actions for layers and channels.
