GNU Image Manipulation Program
Development Branch
------------------------------
This is the unstable branch of GIMP.
Overview of Changes from GIMP 3.0.0-RC1 to GIMP 3.0.0-RC2
=========================================================
Core:
- Histogram now takes into account the image color space for more
correct results.
- Unsupported fonts stderr message is not shown anymore on stable
builds as it is confusing to people (who see often huge numbers,
because there are indeed a lot of font types, especially the legacy
bitmap fonts whose support got broked by Pango, which are not
supported by GIMP, at least for now).
- Drag'n drop color fills now forbidden when "Allow editing on
non-visible layers" is OFF and the target layer is set invisible.
- Improved font matching heuristic for old XCF files, to find the
closest font candidate.
- The "RGB (perceptual)" blend/composite space got renamed "RGB (from
color space)" and a new/real "RGB (perceptual)" blend/composite
space was added.
- The following layer modes' default blend space was changed to the
new "RGB (perceptual)" space: Overlay, Screen, Difference, Dodge,
Burn, Hard light, Soft light, Grain extract, Grain merge, Vivid
light, Pin light, Linear light, Hard mix, Exclusion and Linear burn.
It doesn't break existing XCF files since the actual blend space
used is stored in the file (even when left to "Auto", the XCF format
knows what "Auto" meant at save time).
Graphical User Interface:
- "Check for Updates" button is not shown in About dialog anymore when
"check-release" build option is FALSE.
- Stable (or stable-like such as RCs) builds should not open the debug
console on Windows.
- Some "Default" icon theme icons are used within the "Legacy" icon
theme when missing there, as a temporary workaround to avoid missing
icons ugliness.
- "Layer Name" field in the Layer dialogue is now explicitly focused
on dialog creation (this was the case in 2.10, but there it was
probably "by chance", now it's "by design") because layer names is
often the most common thing people want to change in this dialog.
So it allows quick workflow of opening the dialog, typing a layer
name and hitting Enter.
- GimpSpinScale CSS styling improved for better readability.
- Color Profile labels in the GimpColorSelect widget are now
ellipsized to prevent over-wide container widgets/dockables when an
image has a profile with a long name.
- GimpStatusBar is now aware of icon size changes (soft-proofing
buttons and current tool icons are resized when relevant).
- GimpHandleBar now uses the system's foreground color for its
outline.
- New RC2 splash screen by Sevenix.
- New icons: view-shrink-wrap, view-zoom-fill.
- Updated icons: zoom-fit, zoom-in, zoom-original, zoom-out.
Plug-ins:
- Python Console:
* PageUp/Down usable as alternate of Up/Down to scroll history.
* Ctrl-R and Ctrl-S are now usable for searching respectively
backward and forward through the console command history, with
nice prompt-updating visual feedback.
- BMP import overhaul (for more details, see informative commit
messages in !1932 since this MR got mistakenly squashed into a
single commit):
* 8/16/32 bit-per-channel, int or float, are now imported lossessly
into the corresponding precision.
* New support for 2-bit indexed and ALPHABITFIELDS files.
* More lenient with regards to file header specs.
* Correctly identify OS/2 Huffman encoding.
* Add RLE24 support (RLE24 is a OS/2 variant of bmp compression).
* Add Huffman compression support (another compression variant for
OS/2 bmps). The source code contains a human readable version of
the Huffman code tables (generate-huffman.h). During build, the
actual header huffman.h is generated which includes a digested
form of these tables.
* Load bmp chunk-wise instead of whole image: loads image
tile-height lines at a time to reduce memory allocation for
temporary image buffer.
* Unify RLE24 with RLE4/8 decoding.
* RLE: add alpha channel for undefined pixels: RLE-bmps can have
undefined pixels. Load those bmps with an alpha channel
(GIMP_INDEXEDA_IMAGE) and make undefined pixels transparent.
* Convert gamma/endpoint values in V4 headers to floating point.
* Various fixes and code reorganization.
- Metadata viewer now correctly shows various custom brand markernote
tags as interpreted strings (instead of opaque bytes).
- CMYK PAM files can now be imported.
- Windows shortcut (.link): new plug-in file-lnk (Windows-only) to
support loading shortcuts. This is mostly a wrapper plug-in like the
file-compressor one which redirects to the correct plug-in for the
specific image type.
- Script-fu:
* Do not warn anymore on not exact argument count for
PDB-marshalled procedures (it becomes an info message).
* Script-fu dialogs are now properly activated on macOS through
platform-specific code.
* On macOS, a script-fu dock icon is now only shown when a script
has a dialog.
* GimpDrawableFilter's IDs are now usable to take full advantage of
the various new PDB procedures working on filters.
* Adding a few custom wrappers to libgimp (non-PDB) functions:
- gimp-drawable-merge-new-filter: variable argument procedure
working like libgimp gimp_drawable_merge_new_filter().
- gimp-drawable-append-new-filter: variable argument procedure
working like libgimp gimp_drawable_append_new_filter().
- gimp-drawable-filter-configure: wrapping getting a
GimpDrawableFilterConfig and setting its properties as a
variable arg script-fu procedure.
- gimp-drawable-merge-filter: wrapping
gimp_drawable_merge_filter().
- gimp-drawable-append-filter: wrapping
gimp_drawable_append_filter().
- gimp-drawable-filter-set-aux-input: wrapping
gimp_drawable_filter_set_aux_input().
- PSD: legacy Color Overlay layer styles (legacy 'sofi' data) are now
loaded by GIMP as Color Overlay layer filters.
API:
- Changes in libgimp:
* gimp_drawable_offset() signature changed, with an added GeglColor
argument used when the fill_type is GIMP_OFFSET_COLOR.
* New GimpDrawableFilter and GimpDrawableFilterConfig classes. These
come with ability to create/destroy a filter and various methods
to configure filters, then either append them to the list of
non-destructive filters of a layer, or merge them on any drawable.
* Auxiliary input pads are also supported for GimpDrawableFilter,
though filters with aux input can only be merged (same as in the
GUI), not applied non-destructively for the time being.
* New methods:
- gimp_drawable_get_filters()
- gimp_drawable_append_filter()
- gimp_drawable_merge_filter()
- gimp_drawable_append_new_filter()
- gimp_drawable_merge_new_filter()
* GIMP_LAYER_MODE_REPLACE is now visible/usable in libgimp and PDB
as part of the GimpLayerMode enum type.
- Changes in libgimpbase:
* GimpOffsetType changed: GIMP_OFFSET_BACKGROUND value replaced with
GIMP_OFFSET_COLOR.
* Exif.SonyMisc3c tags are now excluded at export because they cause
a failure of Exiv2 which was having all metadata export fail (see
issue #2670 on Exiv2 tracker).
- Changes in PDB:
* All compat PDB procedures which were special-casing specific GEGL
operations have now been removed. Any usage of these in various
scripts and plug-ins has been replaced by the new
GimpDrawableFilter generic API.
* GeglParamSeed can now be passed through the PDB so that filters
with a seed argument work as expected.
* Compat PDB procedures plug-in-rotate deleted and its usage in
scripts replaced with gimp-image-rotate or
gimp-item-transform-rotate-simple.
Build:
- So many build and packaging improvements that we can't list them
all. :-D
- Our AppImage now supports much more distributions, though we still
consider it experimental.
- AppImage build is now a weekly scheduled job.
- Several unit tests improved with better UI-testing API.
- Pango >= 1.55.0 is now recommended on macOS because of fix pango!745
which fixes a major GUI issue on this platform.
- CI job logs now have collapsed sections for better readability.
- The Windows Installer will not check for SSE anymore since SSE2
instructions are required already for any supported Windows
versions.
- The app-ID of our nightly flatpak (on gnome-nightly repository) is
now "org.gimp.GIMP.Nightly". This will allow the nightly flatpak to
be side-by-side visible next to the stable or dev flatpak without
needed CLI commands.
- AppImage also have its own app-ID too: "org.gimp.GIMP.Continuous"
- Windows installer now defaults to user-mode installs, which is the
recommended defaults by Microsoft since Windows 7. It is obviously
still possible to install system-wide, but won't be the defaults
anymore.
- There is now also an Aarch64 AppImage.
- Minimum dependency version bump: GEGL 0.4.52.
Overview of Changes from GIMP 2.99.18 to GIMP 3.0.0-RC1
=======================================================
Core:
- Conversion to Indexed:
* color precision increased;
* error diffusion in linear RGB while keeping palette generation as
CIE Lab.
- GIMP's GEGL operations:
* Posterize operates with a perceptual gamma;
* Threshold: processing with non-linear RGB;
* Hue-Saturation: using HSLA float as processing space which should be
quicker than previous implementation.
- Welcome dialog:
* Multiple images can be selected and opened at once with Enter key.
* "Show on Start" is now displayed specifically in the "Create" tab.
- Non-destructive layer effects:
* can now be applied on group layers;
* cannot be reordered anymore while being edited.
- More GimpRGB code replaced by GeglColor (space invasion).
- New official software logo!
See: https://gitlab.gnome.org/GNOME/gimp-data/-/blob/main/images/logo/README.md
- Internal procedures are not shown as search actions.
- Non-destructive layer effects are copied together with the layer they belong
to.
- Accessibility: if the "Reduced Motion" (or other names for the same
feature depending on OS/desktop) is checked in macOS, Windows, GNOME
or KDE, then the following animations are disabled: animated credits
in About dialog and some easter eggs.
- New actions:
* layers-select-flattened-previous: moving the selection up visually
in the layers list.
* layers-select-flattened-next: moving the selection down visually
in the layers list.
- The default icon for GimpViewable is now gimp-image rather than
dialog-question. In particular this shows up in some interfaces like
GEGL filters with aux nodes (when the aux input has not been chosen
yet).
- XCF 22: the GEGL Operation version is now stored for each layer
filter.
- GIMP doesn't quit when running non-interactively (i.e. as
gimp-console or with --no-interface) without CLI option `--quit`.
The process can be interrupted anytime with SIGINT (Ctrl-C) which
will trigger a clean exit.
- "Luma Lighten/Darken Only" default blend space is now linear
(instead of perceptual).
- execinfo.h (backtrace() API) is made non-mandatory on Linux, with
proper meson summary showing that the Dashboard backtrace feature
(performance logs) will not work.
- `gimp -v` and crash debug dialog now contain Exiv2 and GExiv2
version information.
- XCF will now refuse to load some types of GEGL ops as
non-destructive layer filters:
* GeglOperationSink operations;
* GEGL Graph ("gegl:gegl") except if the environment variable
GIMP_ALLOW_GEGL_GRAPH_LAYER_EFFECT is set.
- On UNIX-like OSes, at first startup, if a 2.10 folder was not found
in the usual $XDG_CONFIG_HOME, we now lookup the flatpak folder
~/.var/app/org.gimp.GIMP/config/ so that we are able to migrate from
a config created by a flatpak 2.10. Not only this, but we also look
in /var/config/ which is a mount to the same folder, from the host,
inside the flatpak sandbox. This way, both a 3.0 flatpak and
non-flatpak will find the config of the 2.10 flatpak despite the
change done to the flatpak manifest to always use $XDG_CONFIG_HOME
(see Build section).
Tools:
- Gradient tool: the "Repeat" mode "Truncate" has been renamed "None
(truncate)" and reordered to be second in the list, just after "None
(extend)".
- Measure tool: guides can now be created off-canvas.
- Scissors Select: consistently name the tool "Scissors Select" by
dropping the alternate name "Intelligent Scissors" which was only
used in menus.
- GEGL filters:
* new "Merge filter" checkbox in the dialog to directly apply a
filter destructively (like in 2.10 and older).
* Filters with aux nodes can only be merged (no non-destructive
workflow possible for such filters yet).
* Auxiliary nodes now have their nicer name printed in the GUI.
- Paint Select tool now handles the standard Shift/Ctrl modifier for
adding or subtracting to selection. The tool is still experimental
and disabled by default though.
- Color Balance and Hue-Saturation effects work in sRGB space.
Graphical User Interface:
- New "gimp-effects" icon (used in the Layers dockable for non-destructive
layer effects).
- GimpSpinScale text area height is now reduced to improve usability (it is
now easier to find the area to *grab* the scale vs. area to edit the text;
the cursor changing helping to make out one from the other).
- Some cleanups done with test plug-ins and scripts in menus.
- Add option for "Huge" Preview Size in dockable menu.
- Usage of Up/Down and PageUp/Down keys in items tree views are now
multi-item selection aware. Up/Down keys select items in visual
order, walking through item groups (in and out), except when they
are collapsed. PageUp/Down keys select items while not leaving
previously selected items' group level.
- Dockbook: tab scrolling behavior (using scroll to switch between
dockable tabs) which was removed from GtkNotebook in GTK+3 got
reimplemented in our code.
- Palette colors are shown in their own space.
- GimpColorSelect widget (the default color selection tab on the left
of the color selection dialog) now displays the selected color model
(RGB, HSV or LCh) and not only the space/profile (the latter is not
even displayed anymore in LCh which is CIELAB-based).
- Legacy icon theme's tool icons are now all vector.
Plug-ins:
- Plug-ins ported to GimpProcedureDialog: Warp, decompose,
file-pdf-save-multi, qbist, file-xmc, file-tiff-load, file-icns,
file-ico, lava.scm.
- Script-Fu scripts ported to GimpProcedureDialog: addborder,
blend-anim, burn-in-anim, carve-it, chrome-it, circuit, clothify,
coffee, difference-clouds, distress-selection, drop-shadow,
fuzzyborder, old-photo, perspective-shadow, round-corners,
script-fu-set-cmap, selection-round, slide, unsharp-mask,
waves-anim, weave, xach-effect.
- PSD:
* unsupported layers are not dropped anymore (they will usually show
empty instead).
* add warning when exporting multi-layer indexed image (layers will
be merged because PSD does not support multi-layer indexed images,
unlike XCF).
- Script-Fu:
* "Refresh Scripts" (Filters > Development > Script-Fu) is now hidden. It
was broken and anyway not an ideal design choice.
* New call-with-output-string, call-with-input-string and any->string
functions.
* SF-VALUE type was removed.
* script-fu-register-procedure scheme function was added to create
procedures which are not image procedure. These Scheme plug-ins
will use GimpProcedureDialog. The legacy script-fu-register
function still works but is considered deprecated.
* Various plug-ins ported to script-fu-register-procedure:
gimp-online, gradient-example, mkbrush, palette-export,
paste-as-brush, paste-as-pattern, ts-helloworld.
* Colors can now be represented as grayscale with a list of 1 or 2
numerical values.
- All "file-*-save" (and "file-*-save-internal) plug-in procedures have been
renamed to "file-*-export" (respectively "file-*-export-internal").
- Ported to GimpVectorLoadProcedure: file-pdf-load, file-ps, file-svg
and file-wmf-load.
- Arguments ported to GimpChoice in the following plug-ins:
file-raw-data, file-jpeg, file-ps, decompose, blinds, curve-bend,
file-pcx, file-pnm, file-psp, hot, jigsaw, nl-filter, fits,
align-layer, border-average, contrast-retinex, despeckle,
screenshot, file-gif-export, file-heif, file-jp2-load, file-jpegxl,
file-mng, file-tga, file-bmp, file-sgi, file-webp.
- New file-plug-in testing framework. It comes with Gitlab junit reports.
- JPEG XL: half-float import support.
- file-darktable: use the new API which darktable developed from us
since version 4.6 (a new `--gimp` flag on command line). Fallback to
old usage for older versions.
- guides-new: guides can now be created off-canvas.
- ImageMap: zoom factor is now floating point allowing zooming out
past the 1:1 ratio.
- TIFF:
* Added support for loading Sketchbook TIFF layers.
- Goat Exercises:
* Renamed to "Plug-In Examples".
* "Sphere v3..." is now "Plug-in example in Scheme", showing up the
new types of Script-Fu scripts (with a standalone interpreter
rather than as scripts running on the Script-Fu always-on
extension). It is not the same as the historical Goat Exercises,
but it is our best "new Script-Fu" example.
* All other test plug-ins/scripts are hidden in stable releases.
- GIH: max size increased to GIMP_MAX_IMAGE_SIZE.
- Metadata Editor: add ability to set itself transient to any other
window (even across process).
- file-raw-data can now be run interactively.
- The lua binding is now marked experimental because of the too many
unstabilities we experienced.
- Script-fu:
* resource argument defaults are set as a string which is
the name of a resource, or the empty string or "from context" to
default to the context resource.
* Various compat aliases to ancient PDB procedures were removed.
- Python Console: history of commands is saved between runs.
- BMP: new support for loading 64bpp BMPs. Each channel uses 13 bits
(2^13 max value), so it's scaled to fit our 16 bit integer image
mode.
- gradient-save-as-css renamed python-fu-gradient-save-as-css and
histogram-export renamed python-fu-histogram-export for consistent
naming.
- python-fu-eval is now robust to failing script. Instead of crashing
too, it simply returns with a CALLING_ERROR status and pass along
the Python error to the core for proper output.
API:
- All public classes were marked as derivable or final through GObject
macros G_DECLARE_(DERIVABLE|FINAL)_TYPE. It will make it easier to
update them in the future without API/ABI breakage.
- Changes in libgimp:
* gimp_procedure_run_config() can run with no config objects (equivalent to
run the procedure with default arguments).
* New GimpParamColor type (obsoleting GeglParamColor within GIMP) which has
the additional setting `has_alpha` to advertize whether your plug-in
argument accepts only opaque colors or transparent ones (hence generated
GUI can be set accordingly).
* GimpSaveProcedure renamed to GimpExportProcedure.
* GimpSaveProcedureDialog renamed to GimpExportProcedureDialog.
* GimpExportProcedure does not have "drawables" and "num-drawables"
arguments anymore: after much reflection, these arguments were
mostly confusing and many plug-ins were already just using
gimp_image_list_layers() instead. For future advanced usage which
may come in the future, we will add a `GimpExportOptions` argument
instead.
* gimp_export_image() was simplified by removing the interactive
case (which was already hidden hence unused anyway).
* New GimpVectorLoadProcedure class: to be used specifically for
vector-based formats. It will allow to share a common graphical
interface (through the new GimpVectorLoadProcedureDialog), and
will also allow the core application to know which export
procedure is for a vector format, hence special-casing vector
file handling.
* GimpProcedureDialog: new fill_start() and fill_end() class methods
which are ensured to be run exactly once, unlike fill_list().
* gimp_image_add_(h|v)guide() functions can now create off-canvas
guides (same as we can in GUI, now).
* GimpChoice arguments can now generate a GimpIntRadioFrame as
alternative widget in a GimpProcedureDialog (combo box is still
the default widget).
* All GIMP_PROC_ARG_*() macros are now proper gimp_procedure_add_*_argument()
functions (same for aux argument and return value macros).
* gimp_procedure_add_*_from_property() functions were removed.
* gimp_procedure_add_argument(), gimp_procedure_add_aux_argument()
and gimp_procedure_add_return_value() were removed from public API.
* The skipping of _get_ functions by bindings in GIMP
2.99.12, in favor of their _list_ variant, was reverted. Now the
_list_ variants are skipped instead. The original reason was a
limitation of pygobject which is now fixed, and since _get_
functions are historically more common and consistent in our API,
this is what should take precedence.
* New GimpGroupLayer class (subclass of GimpLayer).
* GimpVectors was renamed to GimpPath and all gimp_vectors_ function
renamed gimp_path_ accordingly.
* gimp_buffer_get_image_type() return type is now GimpImageBaseType.
* New GimpExportOptions class and a better infrastructure to handle
intermediate image creation at export, replacing
gimp_export_image() with gimp_export_options_get_image(). This is
also a preparation for future API allowing generic settings during
export (resizing, cropping, adding filters or other actions at
export time).
* New functions:
- gimp_window_set_transient_for()
- gimp_palette_get_colormap()
- gimp_palette_set_colormap()
- gimp_image_set_palette()
- gimp_context_get_emulate_brush_dynamics()
- gimp_context_set_emulate_brush_dynamics()
- gimp_procedure_config_get_color_array()
- gimp_procedure_config_set_color_array()
- gimp_procedure_config_get_core_object_array()
- gimp_procedure_config_set_core_object_array()
* Renamed functions:
- gimp_path_export_to_file() to gimp_image_export_path_to_file()
- gimp_path_export_to_string() to gimp_image_export_path_to_string()
- gimp_path_import_from_file() to gimp_image_import_paths_from_file()
- gimp_path_import_from_string() to gimp_image_import_paths_from_string()
- gimp_palette_entry_get_color() to gimp_palette_get_entry_color()
- gimp_palette_entry_get_name() to gimp_palette_get_entry_name()
- gimp_palette_entry_set_color() to gimp_palette_set_entry_color()
- gimp_palette_entry_set_name() to gimp_palette_set_entry_name()
- gimp_plug_in_extension_enable() to gimp_plug_in_persistent_enable()
- gimp_plug_in_extension_process() to gimp_plug_in_persistent_process()
- gimp_procedure_extension_ready() to gimp_procedure_persistent_ready()
- gimp_buffers_get_list() to gimp_buffers_get_name_list()
- gimp_context_get_dynamics() to gimp_context_get_dynamics_name()
- gimp_context_set_dynamics() to gimp_context_set_dynamics_name()
- gimp_dynamics_get_list() to gimp_dynamics_get_name_list()
* Removed functions:
- gimp_image_get_colormap()
- gimp_image_set_colormap()
- gimp_image_metadata_load_prepare()
- gimp_image_metadata_load_finish()
- gimp_image_metadata_save_finish()
- gimp_resource_chooser_set_clickable()
- gimp_resource_chooser_set_drag_target()
- gimp_resource_select_new()
- gimp_resource_select_set()
+ gimp_fonts_get_by_name()
* GimpResource:
- The ParamSpec arguments (including every subtype) may now have a
default value.
- The ParamSpec arguments now have a default_to_context parameter,
which overrides any default value with a dynamic one
(context-dependant).
* GimpBrushSelect now chooses only a brush (no more widgets to
select a spacing, opacity or paint mode).
* All arrays of items, drawables, layers, channels, paths, resources
(and each specific subtypes of resources) and images as argument
in a libgimp function were now changed to NULL-terminated arrays.
* GimpRunImageFunc (the run() signature for GimpImageProcedure)
doesn't have a n_drawables argument anymore. The drawables
argument is simply NULL-terminated, consistently to other changes
in PDB.
* Various functions now return arrays of GeglColor or arrays of
specific resource types when relevant.
- Changes in libgimpwidgets:
* GimpColorArea: dropped colors are now passed as GeglColor.
* New functions:
- gimp_prop_choice_radio_frame_new()
- gimp_int_radio_frame_set_title()
- gimp_widget_animation_enabled()
* Updated functions:
- gimp_help_connect() has a new `tooltip` argument as a proper
advanced version of gimp_help_set_help_data().
* GimpFileEntry was made private because it is still used internally
but the whole API was deprecated since 2006.
- Changes in libgimpbase:
* GimpRGB and GimpRGB arrays are not supported anymore in the PDB and GIMP
Protocol (only GeglColor and GimpColorArray).
* GimpUnit:
- now a proper class instead of a weird int type extending an enum
type of the same name. This also makes unit parameters actually
introspectable.
- concepts of singular/plural removed from this class because it
just doesn't work out with proper internationalization.
* New functions:
- gimp_int32_array_get_values()
- gimp_int32_array_set_values()
- gimp_float_array_get_values()
- gimp_float_array_set_values()
- gimp_value_array_get_core_object_array()
* Removed functions:
- gimp_unit_get_singular()
- gimp_unit_get_plural()
- gimp_env_init()
- gimp_cpu_accel_set_use()
- gimp_signal_private()
* Renamed functions:
- gimp_unit_get_identifier() to gimp_unit_get_name()
- gimp_float_array_get_values() to gimp_double_array_get_values()
- gimp_float_array_set_values() to gimp_double_array_set_values()
- gimp_param_float_array_get_type() to gimp_param_double_array_get_type()
- gimp_param_spec_float_array() to gimp_param_spec_double_array()
- gimp_value_dup_float_array() to gimp_value_dup_double_array()
- gimp_value_get_float_array() to gimp_value_get_double_array()
- gimp_value_set_float_array() to gimp_value_set_double_array()
- gimp_value_set_static_float_array() to gimp_value_set_static_double_array()
- gimp_value_take_float_array() to gimp_value_take_double_array()
* New argument flag GIMP_PARAM_DONT_SERIALIZE.
* New type GimpParamSpecObject, which is basically a
GParamSpecObject with a default value. It is now used as parent
type for GimpParamSpecColor, GimpParamSpecUnit and all
GimpParamSpecResource subtypes.
* GIMP_PDB_PROC_TYPE_EXTENSION renamed GIMP_PDB_PROC_TYPE_PERSISTENT.
* GimpCoreObjectArray: new alias to NULL-terminated core objects,
such as images, items, etc. The main reason is to make it a boxed
type for proper handling as object properties and PDB argument.
* GimpObjectArray was removed.
* Deprecated GIMP_PRECISION_*_GAMMA enum values have been removed.
- Changes in libgimpcolor:
* All gimp_rgb_parse_*() functions now become gimp_color_parse_*() functions
(GeglColor based rather than GimpRGB).
* GimpRGB, GimpCMYK, GimpHSV, GimpHSL type and all usage was
removed. Related API were deleted too.
* GIMP_RGB_LUMINANCE* macros were made private. They are still used
internally by some core plug-ins but are not exposed anymore as
official API.
- Changes in libgimpconfig:
* Removed functions:
- gimp_config_serialize_strv()
- gimp_config_deserialize_strv()
* Renamed functions:
- gimp_scanner_parse_float() to gimp_scanner_parse_double()
- PDB:
* Triple-backtick blocks in PDB-generated functions' descriptions is
now recognized so that pre-formatted code is kept as-is. E.g.
indentation is not broken anymore in code samples on the gi-docgen
API documentation.
* New "format" PDB type to pass Babl format arguments.
* Most compat PDB procedures were removed, except the few ones we
still use in some of our core plug-ins or scripts.
* All int32 and float arrays are now passed through the PDB without
requiring a size argument preceding it.
Translations:
- New Bengali language support.
Build:
- Minimum dependency version bumps:
* babl 0.1.110
* GEGL 0.4.50
* harfbuzz 2.8.2
- Started a skeleton for unit testing framework for libgimp (only a few tests
so far but we eventually target exhaustivity).
- CI:
* Main CI jobs are now compiled with Clang, as well as Windows installer,
MSIX and Flatpak. Some benchmarks run by Øyvind show we can gain a bit
of performance in some situations in babl/GEGL/ctx codepaths, thanks to
better auto-vectorization support.
* x86 (32-bit) cross-build job for Windows removed.
* "packaging" stage merged back with "build" stage.
* "gimp-debian-x64" job now also generates an AppImage for every commit.
* LLD linker now used in all build jobs (except scheduled GCC and legacy
32-bit Windows jobs).
* Windows cross-builds are not triggered anymore until after GIMP
3.0 (when we'll handle the issues).
* Lua-related files are not shipped anymore with any of the official
builds.
- New gimp-data repository used as a git submodule:
* Various data were moved to gimp-data: icons, cursors, patterns, brushes
and application icon/logo.
* Various files are generated from the source logo: wilber.ico (for Windows
installer), gimp.icns (macOS), desktop application icons for Unix-like
systems, Wilber icons of the "Default" icon theme within the application.
* Splash image and Windows installer's BMP images are generated from the
splash image contributed as XCF.
- Support for .pdb debug symbol files (Visual Studio) was added for
Windows.
- Windows installer: new option to launch GIMP after install.
- Nightly flatpak: HEIC support is now an extension as in our beta
flatpak.
- macOS minimal support was bumped to version 11.
- Python plug-ins are made mandatory, not optional anymore.
- Our flatpak-s will now use $XDG_CONFIG_HOME config folder
unconditionally (not the `~/.var` folder). It won't depend anymore
on whether this config folder already existed or not.
- Only Lua 5.1 and luajit are supported. Later versions have
incompatibilities breaking Lua plug-ins. The detection of the lua
version (by parsing `lua -v output` if needed) is also improved.
- List of languages is now pre-parsed during build, which accelerates
startup a bit (especially on Windows).
- Better error messaging of the configure step when gimp-data
submodule was not initialized or when it is out-of-sync.
- Improved AppStream metadata file validation taking care of the case
when the release date is not yet known.
- The last of deprecated gdk_pointer_grab() calls are now removed.
- Build made more portables for non-GLibc or non-GNU coreutils
environments.
- enable-default-bin meson option now also installs a symlink for a
gimp-3 binary (additionally to default gimp-3.0 and gimp symlink),
or a renamed copy on Windows.
- Installer for Windows will use the new gimp-3.exe binary so that it
can properly register a registry entry based on the major version
only.
Overview of Changes from GIMP 2.99.16 to GIMP 2.99.18
=====================================================
Core:
- New snapping options:
* "Snap to Bounding Boxes": allows on-canvas snapping to either layer
borders or center.
* "Snap to Equidistance": allows to snap a layer to be at the same distance
from a second one that this second one is to a third one, either
horizontally or vertically.
- GIMP is now able to use fonts with custom styles, which Pango is unable to
work with.
- Font names are not unique anymore, which means that GIMP doesn't rename
identically named fonts with #1 or #2, etc. as it used to do. These fonts
with same name are now properly working despite the name clash.
- GimpData now have a concept of collection, which is either a controlled name
for internal data, or a string constructed from the local file path for
external data. This will be used to serialize data objects hence easily
retrieve the proper data even when some data may have duplicate names.
- New palette import support: SwatchBooker.
- Artificially set PANGOCAIRO_BACKEND=fc when running on Windows to use the
fontconfig backend, which enables anti-aliasing on Windows, unlike the
default pangocairo backend.
- XCF:
* Font information are more accurately stored (not only the font name, but
also storing various other attributes and even a file hash in the ideal
case where the exact same font file is available), allowing to find the
right font (if installed) on load with less errors.
* As a consequence of the previous point, new files with text layers will be
saved as a bumped XCF 19 version.
* Older XCF versions with text layers can still be saved using older XCF
versions as long as the text layers are untouched in an edit session.
- "view-zoom-*" actions are not radio actions anymore.
- Improve thumbnail loading algorithm:
1. If there is a GimpThumbnailProcedure, it is run first.
2. Otherwise we check if a thumbnail is in the metadata.
3. As last resort, we just load the full image.
- Generic inter-process transient window reimplemented using opaque GBytes
window identifiers instead of guint32. The goal is to have windows created
by plug-ins be transient to the calling core image window, but also the
other way around: some core dialogs are generated through PDB calls (in
particular resource and drawable chooser dialogs created by gimp_*_popup()
functions) and should be transient to plug-in dialogs.
This works on X11 and Wayland (the Wayland implementation is new, previous
code was X11-only). It should work on Windows too (code exists) but this was
left disabled as it leads to core process hanging (as described in
https://bugzilla.gnome.org/show_bug.cgi?id=359538) and is pending debugging.
There is no macOS implementation yet, and it seems to be missing from GDK as
well.
- Indexed images' colormap:
* Now possible to delete colors if unused.
- Updates for floating data's actions:
* New actions "edit-paste-float" and "edit-paste-float-in-place" for pasting
the contents of the clipboard as floating data with default positioning
algorithm or in-place respectively;
* renames "select-float" to "select-cut-float" which does a cut and paste as
float in one action;
* adds "select-copy-float" which does a copy and paste as float in one
action;
* reorganize a bit the `Edit > Paste as` submenu with sections for the
floating data variants;
* add a "Float" submenu in "Select" root menu, containing the 2 variant
actions "select-cut-float" and "select-copy-float".
- GEGL operation filters are now non-destructive by default: running these
filters create layer effects. The UI is still basic and will be improved
through iterations after GIMP 3 release.
- FG/BG color action code (e.g. "Increase the red channel") are made
contextual, relatively to the active image, working relatively to the
correct color space and TRC.
- Device Status dockable shows context-sensitive colors (the color profile's
name is displayed as tooltip when hovering a fg/bg color status).
- Palettes are now GeglColor-based and are stored with a lot more precision.
Older low-precision palettes are still loaded fine. A single palette can
contain mixed formats (different models and space). A concept of format
restriction was added, yet is currently only used for indexed images'
palettes (whose colors are always and only in the image's format).
- Color History is now space-invaded (colors are stored in their original
format and space).
- Various color selectors (core or modules) are now space-invaded when
relevant. For instance, they show colors in the active image space (not just
sRGB) and display the profile's name when relevant. Also when simulation is
active, some of the color selectors will update their out-of-gamut zone, not
only to be within the image's gamut, but also the soft-proof gamut.
Graphical User Interface:
- "Merge menu and title bar" option is not shown on macOS as it is not usable
there (the main menu is anyway out of the window from the start).
- Top menu has been special-cased for macOS (some items are removed with
"hidden-when" attribute set to "macos-menubar" value) for items which are
also available in the application menu.
- Menu section can now be named with the "section-name" attribute in
GtkBuilder ".ui" files. This can be used as a replacement of the former
"Placeholder" concept which we used to have (and has now been completely
removed).
Plug-ins or GEGL operations which want to make use of sections can use the
"[Section]" syntax. For instance installing a plug-in in the menu path
"<Image>/File/[Open]" will install the menu item at the end of the Open
section (i.e. after the various other open-file actions at the top of the
File menu).
- Some string or naming consistencies were fixed in source strings.
- GimpContainerEntry don't have inline completion anymore. Instead the result
pop-up always appear, even for one result. This is because a limitation of
GtkEntryCompletion: we cannot remove the case sensitivity search (see
gtk#275) which was very bad usage experience because when we reached a
single result, suddenly nothing happened anymore (no popup, no completion)
if case was different on any letter. It's just better to always have popup
with case insensitivity.
This widget is used for instance for on-canvas font selection.
- Some icons were modified with an added light border to make them better
visible on dark themes: gimp-tool-text icons in Color and Legacy icon themes
and gimp-tool-dodge in Color theme.
- Help menu rearranged to be better organized and also to move "About GIMP" as
the last item, which is its more conventional position.
- Many fixes to the default themes (including several cases of CSS rules
leaking from system themes).
- New settings in Preferences to set the interface base font size (this won't
work as well, or at all, for themes which would set absolute font sizes).
- "gimp-wilber-eek" icon is now reused as generic "image-missing" icon too.
- In dockables' grid view, the hovered icon is now highlighted with a
contrasted border.
- GimpPdbDialog (e.g. resource chooser dialogs) are now set to system defaults
for whether or not they use a header bar.
- Shift+Number-row default shortcuts are now transformed into the actual key
in the currently used layout (reciprocally, if numbers are direct access
key, their counterpart shortcuts are similarly updated).
- Colormap dockable:
* New "Delete" button available and sensitive only when selecting an unused
color in the palette.
- Windows: title bar will be switched to light or dark mode based on the
current theme.
- The quit dialog now adjusts its size relatively to monitor height.
- The heuristic to set a cursor when single or multi-selecting items in a tree
view got reviewed in order to avoid unnecessary scroll. As a general rule,
the cursor is always set to one of the selected elements, ideally the last
clicked element unless it is not selected (e.g. removed with Ctrl-click),
then a closest selected element is chosen to avoid unnecessarily scroll of
the item list.
- Pad buttons can now be configured in the "Input Devices" configuration dialog
to run any actions directly (without mapping shortcut key combinations as
intermediate). This only works on Wayland for the time being (yet may work on
more platforms in the future, depending on GTK evolution).
- Themes can now be proposed with up to 3 variants: dark, light and middle
gray, through gimp-dark.css, gimp-light.css and gimp-gray.css CSS files
respectively.
- As a consequence of the previous point, our Default and Gray themes are
merged as one with 3 possible variants.
- Our Color and Symbolic icon themes are merged as a single icon theme named
"Default".
- The "prefer-symbolic-icons" property which can be set in Preferences is only
used when the selected icon theme has both Color and Symbolic styles.
Otherwise the chosen icon theme style prevails. The presence of a style is
determined by the presence of the "gimp-wilber" icon (which becomes
therefore a de-facto mandatory icon in an icon theme) and/or its symbolic
variant.
- When "Override icon sizes" is checked, a few padding values are also
overridden by code in the loaded CSS.
- As a consequence of the previous point, we removed the "Compact" theme which
is now simply possible by overriding sizes to "Small" in Preferences (when
the theme is "Default", it will display the same as the former "Compact"
theme, though it will also work with any other theme).
- "Darker" theme is removed for lack of contributors actually caring for it.
It could be revived in the future as a "Contrast" theme with both a dark and
light variants at the very least.
- The search function in Layers dockable was moved over the Layers list (with
headers), the "link" icon replaced by "search" icon, and is now available
for both Layers, Channels and Vectors dockables (though unsaved for Vectors
because of lack in XCF support).
- The Welcome dialog was improved and its cases extended:
* A new "Personalize" tab contains duplicate settings taken from the
Preferences, in particular the more controversial settings, such as theme
or icon themes, HiPPI support (icon/font sizing), merged menu and title
bar, tool groups or update check.
* A new "Contribute" tab displays a few of the main links for people to
contribute to GIMP.
* A new "Create" tab proposes buttons to create new images or open existing
ones, as well as displaying a list of the last 8 opened images for easy
re-opening.
* A new checkbox (checked by default) allows the welcome dialog to be shown
at each and every startup. Except on new installations or version updates,
the first shown tab will be the new "Create" tab, which is probably the
most useful for day-to-day first dialog shown at startup (on updates, the
"Welcome" tab featuring the new splash screen and a small welcome text is
shown).
Tools:
- Text tool:
* improve markup creation logic when replacing selected text in
order not to create useless styling markup interfering with other
features.
* Alignment for RTL languages is now more consistent with how it works in
other software (such as LibreOffice or Scribus).
* Text layers can now be rendered in the full image's gamut (not sRGB only
anymore), though colors are trimmed to the gamut and are always 8-bit.
* Text outline colors are now rendered in float in the full image's gamut,
without precision loss.
- Paint tools: all painting tools now have an "Expand Layers" option
allowing to auto-expand layers when painting across layer
boundaries. A few additional sub-options customize how this
expansion happens (by how many pixels, filling with transparency,
color, pattern).
Expansion does not grow over canvas boundaries, unless "Show All" is
checked too.
- Color Picker:
* Picked color is internally kept as a GeglColor, doing only last-minute
conversion to the output model/space, hence with better precision.
* RGB, Grayscale and Pixel modes display the profile name of the output
color space (the active image's color space if relevant).
- The Gradient tool now uses GeglColor internally, though GIMP's gradient
format (GGR) still uses old RGB format.
Plug-ins:
- Farbfeld: new image format import/export support.
- OpenEXR:
* Files with single channels are always treated as grayscale, even when
they use non-conventional channel names. A notice message is also
presented to the user in a dialog for information.
- Metadata Editor:
* Various code cleanups and improvements;
* GUI improvements;
* Xmp.plus.ImageSupplierName can now only have one value;
* Improved Creation date handling;
* Synchronization (both for reading and writing) added between some Exif,
Xmp and Iptc equivalent tags. On reading, when equivalent tags have
different values at load, a terminal warning is now outputted.
- Script-fu:
* Generated dialog's titles are not prefixed with "Script-Fu: " anymore.
* Several scripts were removed and moved to gimp-data-extras: erase-rows,
grid-system, select-to-brush, select-to-image, select-to-pattern.
* script-fu-copy-visible was removed (and not moved to gimp-data-extras).
* New test scripts.
- New gimp-help-main script to link to the "Table of Contents" of the manual,
added to the "Help > User Manual" submenu.
- PSP:
* added support to load PSP ICC Profile data.
* fixed vulnerabilities: ZDI-CAN-22096, ZDI-CAN-22097.
* load active selection from PSP file.
* Load guides and grid info.
- Image Map: two new fields to the HTML Link tab and one new field to the
Javascript tab for area properties:
* accesskey: The same as the mnemonic key shortcuts in GTK, to activate an
area of the image map. Depending on the OS, you either hold ALT or
ALT+SHIFT and this key.
* tabindex: What order to select the area when the user presses Tab.
* onClick: Run a Javascript function when the user clicks on the area.
- Esm Software PIX: new import support.
- All plug-ins were ported to the new Gimp*Procedure API using
GimpProcedureConfig instead of GimpValueArray arguments.
- Add Border (script-fu): add a 'Allow resizing' toggle.
- Plug-ins ported to GimpProcedureDialog: van-gogh-lic, dds-write, flame,
histogram-export, lighting, fractal-explorer, map-object, sample-colorize,
compose, curve-bend, depth-merge, selection-to-path, pagecurl, file-cel,
file-svg, file-wmf, smooth-palette, small-tile, film, gradient-flare, tile,
web-page, screenshot.
- JPEG-XL:
* Load metadata via libjxl exclusively.
* Disable GIMP EXIF orientation support, using orientation stored in
codestream instead.
- HEIF:
* Load metadata via libheif exclusively.
* Disable GIMP EXIF orientation support.
- PDF:
* "Layers as Pages" works now for a single layer group with multiple
sub-layers.
- DDS:
* Add support for loading DDS 16- and 32-bit per channel RGBA. Loading is
supported for 16-bit half float, 32-bit float, 16 and 32-bit unsigned and
signed int.
This supports both the DX10 formats and the D3D FOURCC versions.
16- and 32-bit per channel images with less than 4 channels are not yet
supported.
* Add DDS support for loading R8G8, R16 and R16G16 formats.
GIMP can load DXGI variants as well as the older D3DF versions, including
handling of the signed versions.
We also set signed when the pixelformat flag DDPF_BUMPDUDV is set.
* New option to vertically flip dds image on import. This is needed by some
game engines.
* All mipmap generation is done at 32-bit floating-point precision.
* A new cubic filter has also been added (Catmull-Rom) which
rounds-out the existing lineup of cubic filters.
* Better handling of DX10+ files in ddsread.
* Always interpret BC1 cutout pixels as black pixels with 0 alpha,
per the official format specification.
* Import code was rewritten and improved for maintainability and
readability. Importer now supports nearly all non-video
uncompressed formats.
- GIF:
* Remember when a file was stored as a GIF animation to be reused when
overwriting.
- PNG:
* Import/export safe-to-copy PNG chunks.
- HEJ2: new import support. HEJ2 is JPEG 2000 image coded images in HEIF
containers.
- PSD: better wording of the export warning for the path of less surprise.
- Python Console uses theme colors for font colors instead of hardcoded
colors which don't work well on darker themes.
Data:
- Clarified our capitalization rule for data titles: part of titles
inside parentheses also follow title casing.
- "(Hardedge)" generated gradients got renamed "(Hard Edge)".
Translations:
- Many non-translatable strings were made translatable. Various other
localization bugs were handled.
- New Belarusian translation in the Windows installer.
API:
- Changes in libgimpconfig:
* GimpConfig serialization doesn't break anymore if one property
serialization fails. GIMP will now continue to serialize the rest. In
particular, it will allow to retrieve as many arguments as possible
between plug-in runs.
* GBytes (de)serialization support added. It supports gracefully a NULL
GBytes value.
* GeglColor (de)serialization support added. Former GimpRGB properties can
be gracefully converted to GeglColor properties when needed (e.g. to be
able to convert old property or resource files, containing GimpRGB values,
to newer GeglColor).
- Changes in libgimp:
* GimpResource can now be (de)serialized using the data name and collection
so that we are now able to retrieve a used resource quite reliably between
runs.
* For GimpProcedure with no run-mode parameter, the run-mode is considered
non-interactive (e.g. for decision algorithm about whether to reuse
previous settings or not).
* Arguments of type GimpResource and its subtypes are now supported and
GimpProcedureDialog will generate appropriate chooser widgets.
* Arguments of type GimpLayer and GimpChannel will have a proper widget
generated (GimpDrawableChooser) by GimpProcedureDialog, limited to only
the proper drawable subtype.
* All GimpProcedure and its subtypes now have a run() method using a
GimpConfig instead of a GimpValueArray. In particular, the type of the run
argument changed in gimp_procedure_new(), gimp_batch_procedure_new(),
gimp_image_procedure_new(), gimp_load_procedure_new(),
gimp_save_procedure_new() and gimp_thumbnail_procedure_new().
The following 2 run function types had further evolutions:
+ GimpRunLoadFunc: by default, a GimpLoadProcedure will try and load
metadata from a file (if Exiv2 knows the format). The run() function
will be allowed to edit the GimpMetadata object but also the load flags
before it is actually attached to the image, allowing plug-ins to have
custom metadata handling code when needed.
+ GimpRunSaveFunc: metadata handling is integrated in this new version of
the API, since the run() function will pass a prepared metadata object,
which can be modified by plug-in code (if needed). This GimpMetadata
object will be stored automatically by the GimpSaveProcedure
infrastructure if the mimetype argument is set in
gimp_save_procedure_new().
* On plug-in exit, we do not display memory reference hold warnings for Lua,
Javascript and Python plug-ins anymore. The GObject-Introspection bindings
for these languages seem to hold references of their own in some
conditions and anyway plug-in developers don't have any memory management
capabilities available in the chosen languages. It's not like they can do
anything.
* New functions:
+ gimp_procedure_dialog_set_sensitive_if_in()
+ gimp_procedure_dialog_set_ok_label()
+ gimp_procedure_dialog_fill_notebook()
