Core:
Adding support for localized glyphs ('locl') in Text tool depending on the value of the "Language" field in Text tool options.
XCF import nows drop Xmp.photoshop.DocumentAncestors tags after 1000 of them, similarly to what libgimpbase now does. This could happen in XCF files which were created e.g. from a PSD import before we handled the issue in libgimpbase.
XCF import:
Made more robust by ignoring (with a warning) invalid parasites and continuing to load the rest of the file (which might be valid). This way, we are able to salvage more cases of
partially corrupted XCF files.
Additional safety checks to detect broken XCF files.
- Version check can be globally disabled through a value in the `gimp-release` file. This would allow to use the same build on repositories with an update channels (where we don't want update check notifications) and on standalone (where we want them).
User Interface:
Removed titlebar/borders from Windows Splash Screen.
All official themes now have on-hover indicator around eye and link toggles in Layer/Channel/Path Dialog tree-views.
Dark theme:
Hover-on effect on radio menu items to improve readability.
Color icon theme:
Thin contrast border for 'close' and 'detach' to improve their readability against dark backgrounds on mouse-hover.
Plug-ins:
TGA: improving indexed images with alpha channel support (both import and export).
DICOM: Fix endian conversion for photometric interpretation "MONOCHROME1".
File-raw: "RGB Save Type" confusing dialog label renamed to "Palette Type" as on the main dev branch.
Screenshot: option to capture cursor in now available on Windows.
Pygimp: new optional parameter `run_mode_param` (defaulting to True) to register() function of the Python binding, which allows to make the "run-mode" parameter optional when creating a new PDB procedure. This is already used to fix "file-openraster-load-thumb" without changing its signature.
BMP: new PDB procedure "file-bmp-save2" which supports all options available interactively.
BigTIFF: our TIFF plug-in now officially supports BigTIFF import and export.
Import was actually already working transparently if you had a recent enough libtiff. Now the recent libtiff is enforced by dependency requirements.
Export support was added with a checkbox in the interactive dialog and a new "bigtiff" argument in the "file-tiff-save" PDB procedure.
When an interactive export of ClassicTIFF fails for the explicit reason of "Maximum TIFF file size exceeded", the export dialog is raised again with a message proposing to try again as BigTIFF or trying another compression algorithm. This allows because discoverability and understandibility of the issue, while not forcing BigTIFF export (since it might not be supported everywhere).
Unlike the same change on the main dev branch, this backport comes without a dependency requirement bump, which means this will only work if GIMP is built with recent enough libtiff.
Raw: more robust load able to load as much as possible from the file, then fill the rest with white, when offset and dimensions are bigger than actual file size.
Improved support of a few plug-in code for building under UCRT Windows environment (more modern C runtime library than MINGW).
EPS: loading transparent EPS files now supported.
JPEG XL: import backported from the `master` (2.99) branch.
WebP: export has a new IPTC checkbox (saved through XMP) as well as a thumbnail checkbox. (backported from dev branch, since 2.99.
DDS: export has a new flip option (useful for some game engine) as well as a new savetype option to export all visible layers (not only the active one).
TIFF:
Import support for 8 and 16 bit CMYK(A) TIFF files.
* 1, 2 and 4-bit B/W images are now converted to indexed rather than grayscale as it seems that there is more of a use case for these images to be handled as indexed, even tough technically they can be considered grayscale. In the future we could add an option at loading time where the user can choose whether they prefer it to be loaded as indexed or grayscale.
Fix loading images generated by MATLAB's blockproc function.
More robust loading for 8 bps grayscale MINISWHITE TIFF.
Libgimp:
New gimp_plug_in_error_quark() as a generic GQuark/GError domain for plug-ins (backported from 2.99.6).
Gimp_drawable_brightness_contrast() now works in the [-1.0, 1.0] range (it's more of a fix than a change because it's what it should have been from the start).
Better management of modification time in metadata: IPTC tag
Iptc.Application2.DateCreated is not overridden anymore as it is the original creation date of the image. Instead we set the XMP tag Xmp.xmp.ModifyDate for file modification time and Xmp.xmp.MetadataDate for metadata modification time.
Format of Xmp.tiff.DateTime is now properly set with timezone as a consequence of the previous improvement.
Libgimpbase:
Limit to 1000 ancestors when importing images with incredible amount of `Xmp.photoshop.DocumentAncestors` tags, which is most likely due to a bug in some versions of phoshop (in some PSDs, we encountered over 100,000 such tags; it probably makes no sense that a document could have that many ancestor documents). GIMP will now stops at 1000 such tags before dropping the rest and continue loading the file.
Icons:
Chain icons for the Color icon theme reworked from the Symbolic versions (with contrast borders to work on any background color) so that the "broken" and full variants are easily distinguishable.
Translations:
New Galician and Georgian translations for the Windows installer.
- 20 translations were updated: Catalan, Chinese (China), Croatian, Danish, Dutch, Finnish, French, Georgian, German, Hungarian, Icelandic, Italian, Polish, Portuguese, Russian, Slovenian, Spanish, Swedish, Turkish, Ukrainian.
Build:
Bumping minimum GEGL to version 0.4.36.
The Windows installer now has an option /DISABLECHECKUPDATE=true to install the same build but editing the `gimp-release` file to disable update check as newly implemented (see above in Core section).
