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)".- Loading branch information
