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.
