Step one: get rid of all those deprecation warnings that make
it hard to see any other warnings:
- add a lot of dummy API to GimpAction, GimpActionGroup, GimpUIManager
etc. which simply forwards to the deprecated GTK functions, they
will all go away again later
- rename GimpAction to GimpActionImpl
- add interface GimpAction that is implemented by all action classes,
creates a common interface and allows to remove some duplicated
logic from GimpToggleAction and GimpRadioAction, and at the same
time adds more features
file_open_location_response(): guard against g_file_new_for_uri()
returning NULL (which it shouldn't) and an error being NULL (which it
shouldn't either for the same reason). Spotted by Massimo.
...doesn't work
Rename the labels to "built-in sRGB color profile" and "built-in
grayscale color profile" because that's what the option does, it never
converted to the preferred profiles from preferences.
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 Offset filter tool, as a front-end to gimp:offset. The
tool replaces, and provides the same interface as, the drawable-
offset dialog, while also providing live preview and on-canvas
interaction.
Note that we don't simply use a custom propgui constructor for
gimp:offset, since we need a little more control.
There should never be an image using GIMP_TRC_PERCEPTUAL, but things
should work if one is encountered anyway.
In the Image -> Precision menu and the Convert Precision dialog, have
menu items / radio buttons for both non-linear and perceptual, but
hide the perceptual choice unless the image is in perceptual TRC mode.
This should eliminate the possibility to create perceptual TRC images
from the GUI.
...to the Configure Keyboard Shortcuts dialog
Add the button, based on an old patch from Sven Neumann, and make the
buttons in the keyboard shortcuts and input devices dialogs look and
behave the same.
In gimp_open_dialog_set_image(), use a weak pointer for storing the
current image, to avoid a segfault in file_open_dialog_response()
if the active image at the time of the open action has been closed
before confirming the dialog.
This is useful to be able to support file formats other than image
formats. In particular I will use this in the next commit to support a
"GIMP extension" format. When GIMP will open such file, it will
install an extension (not open an image on canvas).
This is an internal flag only, i.e. only usable from core GIMP. File
formats which a plug-in can register are still only image file formats.
When loading indexed images, the image type is not obvious at all
(basically only reference is in the title bar). The main issue is that
if you don't realize it when editing, GIMP appear broken when the
expected colors don't appear on canvas.
Commit e48c239459 was a first step by showing various color widgets with
out-of-gamut warnings contextually. This additional commits will also
allows color selection for painting tools (i.e. foreground and
background colors) to be done within the image palette by default. This
way, the fact that this image impose working with limited color palette
is obvious as soon as you try to edit colors.
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.
We were doing it all the wrong way, fixing one combo box object at a
time. So this commit basically reverses commits 68a33ab5bd, 6dfca83c2a
and a9a979b2d0 and instead runs the same code in the class code. This
way, all objects based on these base classes will have the fix from
scratch.
These improved various other drop-down lists (I found some of them, and
probably not all) as I fixed all GIMP custom widgets based on
GtkComboBox.
Note that it has to be run after filling the list apparently (I had the
problem especially with GimpIntComboBox if running in the _init() code,
then the list widget showed wrong).
...closing this image while the file is being loaded
Ref the image around all calls to file_open_layers() and
gimp_image_add_layers() so it stays around even if the user closes the
display in the meantime.
This commit completely removes the "Edit -> Fade..." feature,
because...
- The main reason is that "fade" requires us to keep two buffers,
instead of one, for each fadeable undo step, doubling (or worse,
since the extra buffer might have higher precision than the
drawable) the space consumed by these steps. This has notable
impact when editing large images. This overhead is incurred even
when not actually using "fade", and since it seems to be very
rarely used, this is too wasteful.
- "Fade" is broken in 2.10: when comitting a filter, we copy the
cached parts of the result into the apply buffer. However, the
result cache sits after the mode node, while the apply buffer
should contain the result of the filter *before* the mode node,
which can lead to wrong results in the general case.
- The same behavior can be trivially achieved "manually", by
duplicating the layer, editing the duplicate, and changing its
opacity/mode.
- If we really want this feature, now that most filters are GEGL
ops, it makes more sense to just add opacity/mode options to the
filter tool, instead of having this be a separate step.
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.
file_save(): make sure we always set an error on failure
file_save_dialog_save_image(): additionally, check that "error" exists
before dereferencing it.
A single icon theme can contain both regular and symbolic icons. Let's
give possibility to switch from one style to the other within GIMP
Preferences.
This won't work very well in all cases yet, especially if an icon theme
only has symbolic icons (and no regular ones) because of inconsistencies
in glib which are being fixed (patches which I submitted and which were
merged in glib on 2018-08-17).
So this will work as expected when we will bump our glib requirement to
whatever is the next release.
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.
The extension dialog will show details about an extension (long
description, screenshot, upstream URLs, etc.) with this widget.
Update the GimpExtensionList to send a "extension-activated" signal on
double click, and make the extensions dialog react on it to display the
extension details for the activated extension.
This is all still mostly a skeleton GUI, but it is starting to get into
shape.
This is using GTK+3 widgets, so I make sure to keep it well separated
from core code. The gimp-2-10 version will have to rework the GUI, but
the GtkListBox and GtkSwitch are nice and make things easier, so it is
worth using them here).
Preview generation for layer groups is more expensive than for
other types of drawables, mostly since we can't currently generate
layer-group previews asynchronously. Add a preferences option for
enabling layer-group previews separately from the rest of the
layer/channel previews; both of these options are enabled by
default. This can be desirable regardless of performance
considerations, since it makes layer groups easily distinguishable
from ordinary layers.
In the preferences dialog, make the "dither images when promoting
to floating point" option insensitive when the "promote impoprted
images to floating point precision" option is unchecked.
...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.
resize_dialog_new(): create the preview with "popup = TRUE", so we
really get a preview of layer size and not of the layer within the
image context like used for the layers dialog.
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.
