and in an attack of madness, changes almost all file plug-in
code to use GFile instead of filenames, which means passing
the GFile down to the bottom and get its filename at the very
end where it's actually needed.
It's an ancient concept from ancient times when we didn't have URIs
and only filenames (not to speak of GFile), and actually even from
before the ancient time before that ancient time when we first had
ones and zeros, and only had zeros.
They are simply setting properties on GimpPlugInProcedures, just like
the other functions in gimpplugin-proc.[ch], so there is no reason to
have them elsewhere and with worse checks and error messages.
and call it gimp_pdb_set_proc_icon(). Change icon registration code in
libgimp/ and app/ so it's now possible to register icons for temporary
procedures.
- remove the menu path and image types from "gimp-plugins-query",
they are available via GimpProcedure, also reorder and rename
its remaining return values to make sense
- remove the "menu_path" parameter to gimp_proc_view_new(),
it can also ask GimpProcedure
- adapt plugin-browser to the new API and make it use GimpProcedure
- fix plugin-browser's tree view to show all menu hierarchies
completely, it was still expecting menu paths that contain
the menu label too
In the generated libgimp wrappers, we can't return object arrays
from a call to GIMP_VALUES_DUP_OBJECT_ARRAY() because it returns
a deep copy and adds a reference to all objects, which the caller
would have to unref.
But we want a shallow (transfer container) copy because we don't want
libgimp proxy objects to be refed or unrefed by any user code.
Therefore, add a HACK that simply memdup()s and returns the
GimpObjectArray's array memory, and leaves the contained object
pointers alone.
Add a show_all parameter to gimp_image_pick_color(), which, when
TRUE, allows picking colors outside the canvas bounds in sample-
merged mode. Forward the display's "show all" mode through this
parameter where applicable (in particular, in the color-picker tool
and the pointer dockable).
GimpDisplay contains only the ID logic and the "gimp" and "config"
pointers, and lives in the core.
GimpDisplayImpl is a subclass and contains all the actual display
stuff. The subclass is only an implementation detail and doesn't
appear in any API.
Remove all hacks which pass displays as gpointer, GObject or
GimpObject through the core, or even lookup its type by name,
just use GimpDisplay.
Turn all ID param specs into object param specs (e.g. GimpParamImageID
becomes GimpParamImage) and convert between IDs and objects in
gimpgpparams.c directly above the the wire protocol, so all of app/,
libgimp/ and plug-ins/ can deal directly with objects down to the
lowest level and not care about IDs.
Use the actual object param specs for procedure arguments and return
values again instead of a plain g_param_spec_object() and bring back
the none_ok parameter.
This implies changing the PDB type checking functions to work on pure
integers instead of IDs (one can't check whether object creation is
possible if performing that check requires the object to already
exist).
For example gimp_foo_is_valid() becomes gimp_foo_id_is_valid() and is
not involved in automatic object creation magic at the protocol
level. Added wrappers which still say gimp_foo_is_valid() and take the
respective objects.
Adapted all code, and it all becomes nicer and less convoluted, even
the generated PDB wrappers in app/ and libgimp/.
Same for returned value though it seems we have no function with none_ok
as return value. At least we have the rule in the generation script for
when this will happen.
This means that images' ownership is not given to caller in particular.
libgimp will now keep a reference of all GimpImage-s it creates and
return this same reference if called again. It also means that you can
now compare images by pointer comparison (as 2 GimpImage objects
representing the same image ID will be equal).
Obviously as a side effect, gimp_image_list() is changed to (transfer
container) as you must only free the container now, not the elements.
Also various other functions creating new images are now (transfer none)
too.
Long-time plug-ins will have to be taken in consideration in a further
step (we currently never free GimpImage for destroyed images in
particular).
I.e.: gimp_image_get_(layers|channels|vectors)(), gimp_image_list() and
gimp_item_get_children().
Instead of returning an array of IDs, these will now return a GList with
the right objects ready to use.
No need of is_id_arg() anymore in pdb/lib.pl. Let's reuse the {id}
value. Also I had to add an additional trick for GimpDisplay which we
will now generate as such in libgimp PDB files, but still need to show
as GimpObject on app/pdb/.
As previously, only the new classes and the PDB generation for a first
step.
By default the new API will be used. But if we build with
GIMP_DEPRECATED_REPLACE_NEW_API macro, then the same function names will
call the old API with ids.
This way, we don't have to update all our plug-ins at once (which I
tried and is very tedious work).
Note that bindings won't have access to the deprecated API at all.
This means that all functions which were returning or taking as
parameter an image id (as gint32) are now taking a GimpImage object
instead.
The PDB is still passing around an id only over the wire. But we create
an object for plug-ins to work on.
This is quite a huge API break, but is probably the best bet for the
future quality. It will make nicer API instrospection (and nicer API in
binding), will fix the issues with pspec on GimpImageID in Python
bindings (which makes the current Python API unusable as soon as we need
to work on images, which is most of our plug-ins!), etc.
Also it will allow to use signals on images, which will be a great asset
when we will finally have bi-directionnal communications (i.e. plug-ins
would be able to connect to image changes, destructions, and whatnot).
And always pass URIs to all file procedures, the ones what didn't
register as "handles remove" will only ever get local file:// URIs.
Change all file plug-ins (also legacy ones) to expect URIs instead
of filenames, and convert to local paths in the plug-in.
The wire protocol should now be almost 100% clean of non-UTF-8 strings.
on behalf of plug-in authors who have no style or can't type.
Instead, simply reject non-canonical procedure names and remove all
code that keeps aroud the original non-canonical shit just to pass it
back to the plug-in.
In the various PDB transform functions, avoid erroneously creating
a floating selection when transforming the image mask, and rather
transform the mask normally.
Remove the special clipping-mode handling for channels throughout
the transform (and drawable-filter) code, and rather use
gimp_item_get_clip(), added in the previous commit, instead. As
mentioned in the previous commit, we only modify the clipping mode
in top-level code, while having lower-level code use the clipping
mode as-is. This not only hides the actual clipping-mode logic
from the transform code, but, in particular, allows code performing
transformation internally to use arbitrary clipping modes.
Also, this commit fixes a bunch of PDB bugs all over the place :)
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.
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.
They only contain private functions and don't need to be installed or
included by gimp_pdb_headers.h.
The PDB generation part is done by adding a "lib_private" variable
that can be set on PDB groups which should not be public API; the rest
is manual Makefile fiddling.
Which return proper GParamSpecs. Incuding some useless testing code in
gimp_procedural_db_proc_info(), to make sure things work, will go away
again soon.
Also generate comments like "Must be freed with g_free()" for all
return values instead of manually and inconsistently having them on
some return values only.
This reverts commit 833666d462.
The _pdb files are an implementation detail and we do not want
separate doc sections for them, the conflicts need so be resolved in
another way.
Otherwise we get a few duplicate sections since some of the non-PDB
files are named similarly.
Fix this GObject introspection warning and other similar warnings:
> libgimp/gimp_pdb.c:28: Warning: Gimp: multiple comment blocks
> documenting 'SECTION:gimp:' identifier (already seen at gimp.c:129).
All foo_pdb.c functions in libgimp regenerated. I have reviewed this a
dozen times, but please have a look, there might well be glitches and
our public API is sortof important...
Not for 2.10 because the GEGL op's result looks different. I have no
clue how softglow is supposed to look at all, but the removed plug-in
did things that can't possibly be done with physical light in a
darkroom, so chances are the GEGL op is more correct.
...for gimp_context_set_antialias(antialias)
Mention gimp_context_set_antialias() in the stroke docs, and mention
the stroke functions in the antialias docs.
Add a "gboolean edge_lock" parameter to GimpChannel::feather() and a
"Selected areas continue outside the image" toggle to the "Feather
Selection" dialog, just like they exist for shrink selection and
border selection. At the end, convert the boolean to the right abyss
policy for gegl:gaussian-blur.
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.
Add "gboolean push_undo" parameters to gimp_image_parasite_attach()
and _detach() and use the API also from undo, instead of implementing
attaching/removing manually and forgetting about the signals.
Fixes updating of the image properties color profile page.
In gimp_image_merge_layers() -- the internal function used by the
various layer-merging/flattenning functions -- process the merged-
layer graph in chunks, using gimp_gegl_apply_operation(), instead
of in one go, using gegl_node_blit_buffer(). Processing in chunks
better utilizes the cache, since it reduces the size of
intermediate buffers, reducing the chances of hitting the swap when
merging large images (see, for example, issue #3012.)
Additionally, this allows us to show progress indication. Have the
relevant gimpimage-merge functions take a GimpProgress, and pass it
down to gimp_image_merge_layers(). Adapt all callers.
Plug-ins are not prepared to handle high-precision brushes/
patterns, even when they're otherwise aware of high-precision
drawables, so make sure to always use compat formats when
communicating brush/pattern data to plug-ins.
Allowing plug-ins to handle high-precision brush/pattern data would
require some additional API.
If you click on a zone filled in several visible layers, you don't
necessarily want the top layer. You may want one below. With this
change, as long as you hold alt, you will loop through all candidate
layers from top to bottom (then looping back top when reaching the
bottom).
In a first alt-click, you will always end up to the top candidate.
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.
The raw PDB wrapper _gimp_drawable_get_format() only transfers the
format's encoding, so we need to add the space from the image's color
profile.
Also fix handling of indexed formats: remove our own indexed format
cache and rely on babl_new_palette_with_space() to return the same
format for any (encoding, space) combination.
Also update the PDB docs to reflect that most magic is happening in
the libgimp C wrapper.
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.
The code was too much spread out, in core and tool code, and also it was
made too specific to fill. I'll want to reuse this code at least in the
fuzzy select tool. This will avoid code duplication, and also make this
new process more self-contained and simpler to review later (the
algorithm also has a lot of settings and it is much cleaner to have them
as properties rather than passing these as parameters through many
functions).
The refactoring may not be finished; that's at least a first step.
The distance map has all the information we need already. Also we will
actually grow up to the max radius pixel (middle pixel of a stroke).
After discussing with Aryeom, we realized it was better to fill a stroke
fully (for cases of overflowing, I already added the "Maximum growing
size" property anyway).
When flooding the line art, we may overflood it in sample merge (which
would use color in the line art computation). And if having all colors
on the same layer, this would go over other colors (making the wrong
impression that the line art leaked).
This new option is mostly to keep some control over the mask growth.
Usually a few pixels is enough for most styles of drawing (though we
could technically allow for very wide strokes).
We don't really need to flow every line art pixel and this new
implementation is simpler (because we don't actually need over-featured
watershedding), and a lot lot faster, making the line art bucket fill
now very reactive.
For this, I am keeping the computed distance map, as well as local
thickness map around to be used when flooding the line art pixels
(basically I try to flood half the stroke thickness).
Note that there are still some issues with this new implementation as it
doesn't properly flood yet created (i.e. invisible) splines and
segments, and in particular the ones between 2 colored sections. I am
going to fix this next.
Since commit b00037b850, erosion size is not used anymore, as this step
has been removed, and the end point detection now uses local thickness
of strokes instead.
I have not added all the options for this new tool yet, but this sets
the base. I also added a bit of TODO for several places where we need to
make it settable, in particular the fuzzy select tool, but also simply
PDB calls (this will need to be a PDB context settings.
Maybe also I will want to make some LineArtOptions struct in order not
to have infinite list of parameters to functions. And at some point, it
may also be worth splitting a bit process with other type of
selection/fill (since they barely share any settings anyway).
Finally I take the opportunity to document a little more the parameters
to gimp_lineart_close(), which can still be improved later (I should
have documented these straight away when I re-implemented this all from
G'Mic code, as I am a bit fuzzy on some details now and will need to
re-understand code).
Right now, this is mostly meaningless as it is still done sequentially.
But I am mostly preparing the field to pre-compute the line art as
background thread.
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.
Add a Babl space parameter to gimp_gegl_color_new() and all utility
functions using it. Pass NULL if the GimpRGB actually is sRGB, pass
the image's layer space if the color was already converted using
gimp_pickable_srgb_to_image_color() or similar.

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.
Add a gimp-register-file-handler-priority procedure, which can be
used to set the priority of a file-handler procedure. When more
than one file-handler procedure matches a file, the procedure with
the lowest priority is used; if more than one procedure has the
lowest priority, it is unspecified which one of them is used. The
default priority of file-handler procedures is 0.
Add the necessary plumbing (plus some fixes) to the plug-in manager
to handle file-handler priorities. In particular, use two
different lists for each type of file-handler procedures: one meant
for searching, and is sorted according to priority, and one meant
for display, and is sorted alphabetically.
Instead just transform the measurement extremities appropriately to
still map to the same points.
To do so, I also added out parameters to gimp_image_resize_to_layers()
so that calling code can get offsets from old origin (as well as new
image dimensions).
Use gimp_fonts_wait(), added in the previous commit, to wait for
fonts to finish loading before operations that depend on font
availability. In particular, this includes font- and text-related
PDB functions, and text-layer rendering.
Fonts should not be blocking startup as this provides a very bad
experience when people have a lot of fonts. This was experienced even
more on Windows where loading time are often excessively long.
We were already running font loading in a thread, yet were still
blocking startup (thread was only so that the loading status GUI could
get updated as a feedback). Now we will only start loading and proceed
directly to next steps.
While fonts are not loaded, the text tool will not be usable, yet all
other activities can be performed.
so plug-ins cannot thaw what they haven't frozen, and the code
can clean up frozen stuff left behind by crashed or broken plug-ins.
Also redo the cleanup code so it only keeps track of the undo group
counts and freeze counts of what *this* GimpPlugInProcFrame did
itself. That should make it even stricter against broken code that
could mess up internals.
These procedures freeze/thaw the corresponding containers of the
image, allowing plug-ins that perform many changes affecting any of
these containers to suppress updates to the corresponding dialogs,
significantly improving performance.
We were only able to translate selections and layers (bot not channels
and paths) via the PDB, this new procedure fixes that. Deprecation of
old API and some more transform consistency to follow...
In the gimp-channel-combine-masks PDB wrapper, only push an undo step
if the modified channel is attached to an image. It's a completely
reasonable use case to combine unattached channels.
Don't unconditionally overwrite all the proc's description, author
etc. Instead, try to preserve them and append the "Deprecated" notes
to the help texts and generated comments.
Only affects one procedure because we killed the meta info of all
other deprecated procs so far, but now we don't have to do that any
longer.
Add new PDB group "drawable_edit" which has all procedures from the
"edit" group which are not cut/copy/paste.
The new group's procedures don't have opacity, paint_mode
etc. arguments but take them from the context instead. Unlike the old
gimp-edit-fill, gimp-drawable-edit-fill now uses the context's opacity
and paint_mode.
The new gimp-drawable-edit-gradient-fill procedure uses even more
context properties which are also newly added with this commit
(gradient_color_space, gradient_repeat_mode, gradient_reverse).
And some cleanup in context.pdb.
This is still WIP, nothing in the edit group is depcreated yet.
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
Make sure a channel -> selection -> channel roundtrip never does any
gamma conversion.
In gimp_channel_duplicate(), make sure a created channel has the
right format, and the right data. Fixes selection -> channel.
When switching off quick mask, call gimp_item_to_selection() instead
if gimp_selection_load(), the latter was implementing a shortcut which
is now wrong.
Remove gimp_selection_load() which is now unused.
Unrelated: also remove gimp_selection_save(), it was an obvious
3-liner used only twice.
This property is currently only used for gimp_edit_blend() to control
how are computed distances. In the future, it could be used for more
functions making use of "gegl:distance-transform" operation, or even for
other algorithms, if relevant.
This new property obviously comes with 2 new PDB calls:
gimp_context_get_distance_metric() & gimp_context_set_distance_metric()
The enums have to be menually registered in pdb/enums-external.pl.
Currently supports enums from GEGL only.
Add enum GeglDistanceMetric as first external enum.
Our composite modes don't correspond directly to the Porter-Duff
operators after which they're named, and these names aren't too
descriptive anyway.
Rename the composite modes as follows:
Source Over => Union
Source Atop => Clip to Backdrop
Destination Atop => Clip to Layer
Source In => Intersection
Update relevant code, including UI text, enumerator names, function
names, and action names.
We don't want an infinite number of traces because it takes some time to
get. Until now I was keeping track of traces in app/errors.c, but that
was very sucky because then I was limiting traces per session. Instead
save them as a variable of a GimpCriticalDialog instance. Therefore only
generate the traces for WARNING/CRITICAL at the last second, when
calling the dialog.
When too many traces are displayed, just fallback to just add error
messages only. But then even errors without traces can be time-consuming
(if you have dozens of thousands of errors in a few seconds, as I had
the other day, updating the dialog for all of them would just freeze the
whole application for a long time).
So also keep track of errors as well and as last fallback, just send the
remaining errors to the stderr.
which is just a #define to g_assert for now, but can now easily be
turned into something that does some nicer debugging using our new
stack trace infrastructure. This commit also reverts all constructed()
functions to use assert again.
Add "clamp-input" (which clamps the input values to [0..1])
and "clamp-output" (which clips the final result to [0..1]),
properties, parameters and GUI to:
- GimpLevelsConfig
- GimpOperationLevels
- The levels tool dialog
- The gimp_drawable_levels() PDB API
The old deprecated gimp_levels() PDB API now sets both clamping
options to TRUE which restores the 2.8 behavior.
Also reorder some stuff in GimpLevelsConfig and elsewhere so the
levels parameters are always in the same order.
It never belonged inside "tools". Also rename its "pdb" subdirectory
to "groups". This had to happen before 2.10 so cherry-picking between
branches doesn't become a nightmare in the future.
