------------------------------ GNU Image Manipulation Program 2.10 Stable Branch ------------------------------ This is the stable branch of GIMP. Unlike earlier stable branches, we do allow some new features here, if they are not too invasive. Otherwise, this branch is only for bug-fixes. Overview of Changes from GIMP 2.10.30 to GIMP 2.10.32 ===================================================== 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 2.99.8) - 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 though 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 Photoshop (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). Overview of Changes from GIMP 2.10.28 to GIMP 2.10.30 ===================================================== Core: - Do not follow subpixel font rendering choice from system settings for text layer rendering. These systems are useful for GUI rendering on a screen of a specific type and pixel order. Yet when rendering an image which can be zoomed in or out, showed on various screens or even printed, subpixel font rendering doesn't make sense. - Rewrite the core selection drawing logics so that it works on macOS Big Sur and over. This is a backport (adapted to GTK+2) of the fix brought in GIMP 2.99.8 for Wayland and macOS. - Ignore MakerNote metadata tag at export and only store the tags that go in it, hence avoiding partial invalid metadata. - Color picking from Colors dockable can now use the Freedesktop portal. - On Windows, move from GetICMProfile() to WcsGetDefaultColorProfile() because the former is broken in Windows 11. Plug-ins: - metadata-viewer: improve how XMP tags with multiple values are handled and shown (now each value on a separate line for better readability). - metadata-editor: * XMP array tags of type BAG and SEQ are now on separate lines. * Comparing XMP tags with equivalent IPTC tags with multiple values, each value is compared individually, instead of comparing the list as a whole. - Many robustness improvements and other fixes to the metadata plug-ins. - AVIF: prefer AOM encoder for export (rather than "rav1e", default of libheif, yet with worse performance). - PSD: * Skip sanity check for mask of rendered layers as some layer mask have invalid dimensions in such cases. They will now be loaded correctly. * Fixed loading of CMYK PSD files without alpha. * Fixed loading of CMYK images without layers. * Fixed loading of merged image of a 16 bit per channel RGBA PSD file with the alpha channel opaque. - PBM: large file export now always works and does not depend anymore on the platform's long int size. - Screenshot: * GNOME shell implementation dropped because the D-Bus API has been restricted to core components for security reasons, thus our plug-in was failing. * KDE portal moved as last fallback after the X implementation (when running on X) and Freedesktop portal, because KDE is also starting to block API calls for security reasons. Installer: - Extension .avif now associated to GIMP. - Drop codepage conversion, use UTF-8 for language files. Build: - macOS support officially bumped to macOS 10.12 (Sierra). We would usually try to avoid doing this within a stable release but the conditions (lack of contributors) is such that it is hard to avoid. Overview of Changes from GIMP 2.10.26 to GIMP 2.10.28 ===================================================== Translations: - 10 translations were updated: Catalan, Chinese (China), Finnish, Italian, Polish, Russian, Slovenian, Spanish, Swedish and Ukrainian. Build: - Fix uninstalled white-border prelight file. Overview of Changes from GIMP 2.10.24 to GIMP 2.10.26 ===================================================== Core: - Dashboard now has memory support in OpenBSD. - Default shortcuts Shift+[ and ] for tool size changed to { and }. - Performance improvements for GIMP on macOS Big Sur: these improvements were actually already applied in our macOS packages since GIMP 2.10.22, but were applied upstream directly only now. User Interface: - Dark theme: improve accessibility of GtkRadioButton by adding a white border on mouse-hover. - Gray theme: set light background for selected text in Layers and Paths dockable dialogs to make text visible. - Dark, Gray and Light themes: remove 3D shadow box around eye and link toggles in Layers, Channels, and Paths dockable dialog tree views. Plug-ins: - Improved DDS support and fix some red/blue bit swap for RGB10A2 DDS. The plug-in version is incremented so that it is able to catch and correct previously incorrect RGB10A2 images exported by older versions of our plug-in. - DDS files with "L16" - a 16 bit luminance channel - are now loaded in 16-bit. - DICOM images: * Support for planar configuration. * Support for deprecated big endian transfer. - TIFF images: * Thumbnail storing now done by storing the thumbnail as the second page in the file (through Exiv2) and setting metadata "Exif.Thumbnail.NewSubfileType" to 1 (reduced resolution image) instead of storing the thumbnail as a subifd. This was done because of a Windows bug locking TIFF files with thumbnail stored as subfid. * Symmetrically, loading will ignore pages marked as "reduced resolution image" (i.e. it will consider them as thumbnails), as well as try to guess if a page (without subfile type) is a thumbnail when it meets following criteria: second page with YCbCr PhotometricInterpretation, old style jpeg compression while the first page has a different PhotometricInterpretation or compression. Script-fu: - New (dir-make "/dir/name" mode) function to create a directory. Translations: - New translations for the Windows installer: Vietnamese, Lithuanian. - 13 translations were updated: Catalan, Chinese (China), Croatian, Dutch, German, Lithuanian, Polish, Russian, Slovenian, Spanish, Swedish, Ukrainian and Vietnamese. Build: - On Windows, *.rs file extension is not associated with SUN Raster images anymore. The reason is that this file extension is mostly used for Rust code files nowadays. If Windows could detect file formats with "magic numbers" (i.e. byte identifiers), it would not be a problem, but since it relies apparently only the extension, it's better to remove this association. - Oppositely on Linux and other Unix-like systems using desktop files, add the image/x-sun-raster MimeType which was forgotten (there, detection should be fine and not depend on file extension). - gimp30-tips.mo is not installed anymore (only used during the build to generate gimp-tips.xml with multiple language support). - --enable-check-update now has an "auto" value, which is the new default. It is equivalent to "yes" for Windows and macOS and "no" in all other cases. - New unit test to check that localizations listed in the installer script match available po files in po-windows-installer/. - "msys*" host value now detected as Windows builds. - Bumping minimum GEGL to version 0.4.32. Overview of Changes from GIMP 2.10.22 to GIMP 2.10.24 ===================================================== Core: - Ignore Pentax and PentaxDng metadata at export because they are unsupported. - DBus calls (remote file open, typically with double click on file browser; and remote command run) are now processed after all command line files (in case of calls during startup) and in the call order (FIFO) for consistency. Some timeout has also been added to not spam the core process with non-processable DBus calls during startup. - Display profile name in "Color space" field of Image Properties and improve ellipsis & wrap on dialog fields whose contents' size is not controllable together with better dialog size management. - Fix stack overflow when loading very large XCF files on Windows. - Point snapping now works outside the canvas. This is used for snap to guides, grid and vectors. Snap to grid only works off-canvas when "Show All" is enabled because off-canvas grid is not visible otherwise, though snap to guide and vectors will always work off-canvas. Libgimp: - Various metadata improvements: * Improve reading of iptc tags that appear more than once. Plug-ins: - JPEG export will better advertize when metadata export fails, possibly with relevant error message. Image export would not fail, but at least we make the person aware metadata is not properly exported. - More robust TIFF import and export: * Better handling of Exif.Thumbnail.* tags on export. * Import now ignores TIFF pages with invalid directory (rather than freezing and output an error to warn of possible data loss). * Import attempts to count the directories by reading them when the headers does not announce any directory, which allows to salvage images with improper header. Also if reading of a directory fail, we now output a message to warn of possible data loss. * Fixed loading 2 and 4-bit TIFF images in grayscale and indexed. * Improve support of ExtraSamples fields with non-conformant TIFF files. * Improve loading of multi page tiffs with linear TRC. * More safety checks as a result of fuzz-testing. * Improve loading of MinIsWhite and MinIsBlack images. - GeoTIFF tag support added (recognized and stored into image parasites at import, then exported back when TIFF format is used) with appropriate "Save GeoTIFF data" checkbox (checked by default and sensitive only when the metadata parasite is present) to disable GeoTIFF metadata export when not desired. - The metadata viewer and editor got a big cleaning and refactoring pass, as well as various fixes and several improvements: * Fix handling of IPTC tags which can appear more than once (such as "Keywords") in both the viewer and editor. * Always read both the IPTC and XMP equivalent tags in the editor, instead of assuming they are necessarily the same. * More IPTC equivalents of XMP tags added: + Iptc.Application2.LocationName <=> Xmp.iptc.Location + Iptc.Application2.BylineTitle <=> Xmp.photoshop.AuthorsPosition + Iptc.Application2.CountryCode <=> Xmp.iptc.CountryCode + Iptc.Application2.Writer <=> Xmp.photoshop.CaptionWriter * The editor now properly saves IPTC tags. * Improve UTF-8 conversion to avoid double string conversion (hence actually breaking encoding). * Use proper unit abbreviations and proper label casing. * GPS data is now properly formatted with better precision and with translatable string parts and tooltips are added to explain how to correctly edit GPS data (latitude, longitude, altitude). Also seconds part of latitude/longitude is now saved with more precision and altitude details now switch from .1m to .10m. * Better error reporting when the editor fails to write a tag, with proper GUI error, so that such error do not go unseen. * Better error handling when closing the editor or viewer too, and improve error handling when the calendar dialog fails. * Use a logging domain for debugging-only messages which pollutes the output. * Xmp.iptc.CreatorContactInfo/Iptc4xmpCore:* override the shorter forms Xmp.iptc.Ci* if both are present, since the longer form is more common. * Improve saving of XMP metadata. * And more bug fixes and refactoring steps to get rid of duplicate code. - PNG will now prompt only for layer offset different from zero. Some software were always setting an offset of 0 (e.g.: POV-Ray v3.7) so GIMP would unecessarily prompt the user until now for PNG created by such software. - BMP: * allow loading of BMP images with incorrect BI_BITFIELDS compression. * support loading more bit depth such as 24bpp images. - file-darktable: * support updated Lua API of darktable 3.6 and beyond; * Adding environment contents to debugging output when DARKTABLE_DEBUG env variable is set. - PDF import: * New option to reverse order of layer. * Support fractional DPI (allowing accurate page dimensions). - DDS: * Set blue channel of BC5 dds images to 0 instead of 255. * Fix DDS BC5 compression/decompression with Red and Blue swapped. We detect images created by an older GIMP on loading and swap the channels back. - HEIF: * Removes the "HDR" mention on HEIF 10/12-bit export because high bit depth does not necessarily means HDR. * Runtime detection of HEIC and AVIF file formats (depending on available encoders and decoders), which allows afterwards update of the dependency, but also allows usage for a single format (e.g. for distributions which want to support only AVIF). * With libheif 1.10, visually lossless export is possible for 10/12 bit depths too - PSD: * More flexible reading of layer mask record size, skipping invalid or unsupported mask info size, hence allowing us to load more PSD files (at least the part of a PSD we support instead of failing the whole import altogether). - G3 fax images: * Improve error handling when loading. * Be more forgiving on bad lines which were quite frequent on older fax images, allowing to salvage some old images. Build: - Some configure fixes for autoconf-2.70 support. - Adwaita's legacy "software-update-available" icon is now bundled with GIMP to handle the possibility of them being absent from your system theme (typically it was missing on our Windows build). Installer: - New Slovak translation. Translations: - Kabyle translation added. Build: - Bumping minimum GEGL to version 0.4.30. Overview of Changes from GIMP 2.10.20 to GIMP 2.10.22 ===================================================== Core: - Verbose version information (`gimp-2.10 -v` on command line, or debug output) now displays Flatpak related information when available. This is especially useful for debugging (such as the exact Flatpak build hash, the runtime version, the installed Flatpak extensions, permissions, etc.). - OpenCL settings has now been moved to the Playground tab in Preferences. - On stable builds, "Playground" tab is now visible in Preferences if any of the experimental features has been enabled, even without the CLI option `--show-playground`. Tools: - "gegl:matting-levin" now the default engine of Foreground Select tool (when present, as it is an optional feature) as it performs a lot better. - GEGL operations now display a "Sample merged" checkbox in Tool Options. This will be used when the operation allows to pick a color (hence one can pick from the edited layer or from visible data). - "Sample merged" now defaults to being activated in Color Picker and GEGL tools as it seems the less confusing for beginners who don't know of the option yet (according to a small poll we ran). User interface: - In GimpSpinButton, don't propagate Enter key-press events if updating the spin-button's value in response changes the entered text. This prevents confirming dialogs when hitting Enter after entering a math expression in size entries, updating their value instead. Likewise, don't propagate Escape key-press events if a new value was entered, and restore the original value instead. - GimpMemSizeEntry improved to show appropriate binary prefixes (kibibyte, mebibyte and gibibyte) instead of decimal ones, to round properly when using higher units, and to not lose accuracy when possible when displaying in higher units. - Several of the biggest pages of the Preferences dialog are now scrollable, allowing the dialog to fit on smaller displays. Plug-ins: - Add a new GIMP_EXPORT_NEEDS_CROP export capability, which causes gimp_export_image() to crop the exported image content to the image bounds; this is useful for formats that support layers, but have no concept of global image bounds, hence cropping is the only way to enforce the image bounds. When showing the export dialog, give an option to either crop the layers to the image bounds, or to resize the image to fit the layers. - Content type `image/webp` is now recognized (and not only `image/x-webp` as both seem to be in used and this format is unfortunately not yet listed in IANA media types (so various content types are in use, no clear standard apparently). - DDS import is now a bit more permissive, allowing to load some files with invalid header flags regarding compression, while we are able to know the right compression from other flags. This allows to recover invalid DDS files exported by other software. - JPEG detection improved to be more generic and reliable. - HEIF support improvements: - AVIF importing and exporting added (requires libheif 1.8.0+) - 10/12-bit importing and exporting now available for HEIC/AVIF - NCLX color profile import (link with LittleCMS) - Metadata support when importing - "Lossless" option is now called "Nearly lossless (YUV420 format)" because this is actually what it is, hence previous naming was misleading. - TIFF support improvements: - Add an option to crop the layers to the image bounds when exporting individual layers (using GIMP_EXPORT_NEEDS_CROP), since TIFF has no concept of global image bounds otherwise. Cropping is enabled by default. - TIFF export will not override "DocumentName" metadata tag anymore. - Stop writing file paths into TIFF DocumentNames as file paths can contain confidential information such as usernames and directory structures, making the previous behaviour a potential privacy and security risk. - Fix a file descriptor leak case which may have prevented a file from being opened on Windows. - Multiple improvements in the PSP import plug-in: - support reading raster layers of PSP version > 6, - support reading 16-bit integer PSP files, - support reading grayscale and indexed PSP files, - support PSP images with zero-length layer names, - fix wrong layer offset of layers, - fix reading layer names with high bit ASCII characters, - fix incorrect loading of PSP images with uncompressed channel data, - fix reading of creator block data of PSP images, - better error messages describing yet unsupported features, - improve reader stability by always using the block/chunk length. - Spyrogimp now works on Grayscale images and clutters less the undo history. - "Orientation" metadata is now reset whether you accepted to rotate the image or not when importing an image. - XPM does not export a "None" (transparent) color when unused. - BMP always include color masks when exporting BMP with color space info, as mandated by BITMAPV5HEADER specification. Debugging: - Add progressive performance logs: progressive logs contain complete information after each recorded sample, by writing partial address maps at each sample, containing all new addresses introduced by the sample. This allows recording complete logs even in cases where they can't be properly terminated, such as when GIMP crashes or freezes in the middle of the log. Progressive logs are disabled by default, since they potentially increase the sampling cost. They can be enabled through a toggle in the log file-dialog, or through GIMP_PERFORMANCE_LOG_PROGRESSIVE environment variable. Performance log viewer can now process progressive performance logs too. - Allow controlling performance-log parameters through the UI. Build: - new `distcheck` step in Continuous Integration. Bug fixes: #2275, #2668, #2874, #3481, #3868, #4061, #4155, #4328, #4505, #4536, #4560, #4816, #5043, #5069, #5208, #5219, #5226, #5232, #5274, #5275, #5357, #5358, #5472, #5530, #5584, #5592, #5623, #5630, #5651 Translation updates: - Basque, Catalan, Chinese (China), Croatian, Danish, French, German, Italian, Japanese, Kazakh, Polish, Russian, Spanish, Swedish, Turkish, Ukrainian Developers/contributors: - Daniel a Simona Novomeská, David A.

The option is unchecked by default, as it is the non-destructive behavior, which also means the default behavior is changed. - Crop tool in image crop mode will not crop layers with "Lock pixels" on, anymore, even if "Delete cropped pixels" is checked. - Painting tools can now restore opacity and blend mode from presets. User interface: - Image / Precision renamed to Image > Encoding - Tool groups can now display their tool list on hover rather than on click. This can be set in Preferences, in the Toolbox tab. - Improved update notification GUI in About dialog, and now also showing an update comment when one was set in gimp_versions.json. - Palette Editor dockable: the color index in the current palette is now shown in front of the color name. Plugins: - In file-psd, make the data_start and data_len fields of the PSDimageres and PSDlayerres structs unsigned, to avoid potential overflow/sign-extension - file-raw: Canon CR3 files are now properly recognized by GIMP and sent to your raw developer software of choice. - PNG and TIFF export: "Save color values from transparent pixels" defaults now to not saving color values (i.e. channels set to 0) when alpha channel is present and 0 itself. - PDF import: multi-pages are now imported in bottom-first order, similar to animated formats, and also similar to defaults for PDF export. This brings consistency but break existing behavior, hence needs to be noted. - Added support for exporting 16-bit PSDs, read and write channels from/to PSd in the right order Filters: - The 'Vignette' filter now has on-canvas controls - New 'Filters -> Blur -> Focus Blur' filter with on-canvas controls to emulate out-of-focus blurring - New 'Filters -> Blur -> Variable Blur' filter that uses an aux mask input to blur an image with variable intensity - New 'Filters -> Light and Shadow -> Bloom' filter Updated translations: - British English, Catalan, Chinese (Taiwan), Dutch, Finnish, German, Greek, Italian, Korean, Polish, Romanian, Russian, Spanish, Swedish, Turkish, Ukrainian Icons: - Replace fileicon.ico with version contain 24x24, 64x64, 128x128, and 256x256 sizes for Windows icon - Replace wilber.ico with version containing 128x128 size of Windows icon Bug fixes: - #189, #354, #872, #1439, #3405, #3533, #3558, #3777, #3841, #4094, #4328, #4363, #4487, #4618, #4641, #4663, #4696, #4734, #4745, ##4793, 4827, #4846, #4858, #4871, #4895, #4904, #4919, #4967, ##4968, #4992, 4996, #5009, #5010, #5033 Developers: - Ell, Jehan, lillolollo, Marco Ciampa, Michael Natterer, Øyvind Kolås, pesder, Salamandar, Sergio Jiménez Herena, Simon Budig, T Collins, woob Contributors: - Nikc, Sabri Ünal, Michael Schumacher, Jernej Simončič, luz.paz Translators: - Alexandre Prokoudine, Anders Jonsson, Bruce Cowan, Cristian Secară, Daniel Korostil, Daniel Șerbănescu, Dimitris Spingos, Jiri Grönroos, Jordi Mas, Nathan Follens, Piotr Drąg, Rodrigo Lledó Milanca, Sabri Ünal, Seong-ho Cho, Tim Sabsch, Yuri Chornoivan, Георгий Тимофеевский Overview of Changes from GIMP 2.10.16 to GIMP 2.10.18 ===================================================== Core: - In gimp:replace, when compositing the same content over itself, i.e., when the input and aux buffers share the same storage and same tile alignment, pass the input buffer directly as output, instead of doing actual processing. In particular, this happens when processing a pass-through group outside of its actual bounds. User interface: - Add new Symbolic-High-Contrast and Symbolic-Inverted-High-Contrast themes, which are automatically-generated high-contrast variants of the (original) Symbolic theme. The contrast factor is settable in the makefile, and is currently at 1.5 for both themes. - Rename tools/invert-svg to tools/svg-contrast, which now takes a contrast-factor argument, and adjusts the input SVG contrast, instead of just inverting it. Note that we can still use the tool to invert icons, using a contrast of -1. - Allow horizontal scrollbars in all the Preferences dialog tree- views, so that they don't limit the minimal width of the dialog (in particular, the UI- and icon-theme tree-views may contain arbitrarily-long paths). - Draw a border around the color FG/BG color areas as a pair of black and white rectangles instead of letting GTK do this. This imporoves the legibility of borders, especially in dark themes. Tools: - In GimpPaintTool, when not snapping brush outline to stroke, make sure to properly snap the cursor position to 15-degree angle multiples in line mode, not only when painting the line, but also during motion. Plug-ins: - Add naive support for CMYK 8-bit PSD files Updated translations: - Basque, Catalan, Danish, Polish, Spanish, Swedish, Ukrainian Bug fixes: - #4643, #4634 Developers: - Ell, Massimo Valentini Translators: - Alan Mortensen, Anders Jonsson, Asier Sarasua Garmendia, Daniel Korostil, Jordi Mas, Piotr Drąg, Rodrigo Lledó Milanca Overview of Changes from GIMP 2.10.14 to GIMP 2.10.16 ===================================================== Core: - In gimp_gegl_apply_cached_operation(), use gint64 for storing the total and processed pixel counts used for reporting progress, to avoid overflowing when applying an operation to a large image. - In GimpFilterTool and gimp_drawable_apply_operation(), use gimp_drawable_filter_set_add_alpha() to add an alpha channel when applying an operation that specifies "needs-alpha" to a drawable that can have alpha. - In GimpFilterTool, move all the drawable-filter option setup to a new gimp_filter_tool_update_filter() function, and call it whenever the drawable-filter's options need to be updated. This avoids duplicating logic in various places. - Improve the efficiency of decoding RLE data when loading ABR brushes, by reading entire scanlines into a buffer all-at-once, instead of reading the stream byte-by-byte. - GIMP now optionally phones home to find out if there's a new version available and then tells the user if there is one indeed. It also keeps track of the installer revision and then warns if there's a newer installer available. This can be disabled in Preferences. In that case, users still have the option to manually check for an update via the About dialog. The feature can be disabled entirely with the '--disable-check-update' configure switch. Tools: - New 3D Transform tool where you can set vanishing point, camera's focal length, and the move and rotate layer, selection, path, or image in 2.5 space. With the "Unified interaction" option enabled, all three interaction modes of the grid (camera, move, and rotate) are available simultaneously. In this mode, the inner and outer regions of the item are used for moving and rotation, respectively, and the vanishing point is controlled through through a handle. - Transform tools now respect the Clip option and update the canvas preview accordingly. - New "Composited preview" option allows respecting layer's blending mode and position in the layer stack rather than rendering it as an overlay on top of the overall layer stack. This simplifies creating complex layer compositions greatly. The option requires mipmaps to be used and thus is disabled by default. It also comes with an experimental "Synchronous preview" suboption to render the composited preview synchronously. This reduces the lag for painting the preview, but can harm responsiveness for bigger images, where rendering the preview is slow. - Add a new "Preview linked items" option to the transform-grid tools. When this option is enabled, together with composited previews, the transform preview includes all linked layers and channels when transforming a layer/channel. Paths are currently unsupported. - New widget called GimpPivotSelector, a 3x3 grid of toggle buttons, is now used for selecting a natural pivot position (e.g. for a transform) relative to an item: its center, its corners, and the midpoints of its edges. Currently used in Rotate and 3D Transform tools. - Add "Show all" support to the Bucket Fill tool in line-art mode - Color picker and sample points now support displaying values in Yu'v' (CIE 1976 UCS) color space. - The Symmetry Painting dock now has an "Enable reflection" option that allows painting patterns resembling a kaleidoscope. - Transform clipping is temporarily disabled for layer groups. No preview other than 'Adjust' works anyway. This will be fixed later on. - Construct a box-filtered mipmap hierarchy for the original brush on-demand, and the closest mipmap is used as the resampling source for downscaled brushes, significantly improving the output quality. - Now that painting is done in a separate thread, the display update rate has a far smaller impact on it. Increase the GimpDisplay update rate, which handles image updates, to 60 FPS, and the GimpDrawTool update rate to 120 FPS. In particular, the latter change makes the brush outline motion much smoother. - In the Airbrush tool, increase the maximal stamp FPS from 15 to 60, and change the corresponding maximal Rate value from 150 to 100. This technically affects tool presets, but we'll live. - Add a new "Snap brush outline to stroke" toggle to the "Image Windows" preferences page. When enabled, the brush outline in paint tools snaps to the individual dabs while painting, which is how it worked before version 2.10.16. Disable the option by default. This seems to be what most other programs are doing, and it does give paitning a smoother feel. - The Warp Transform tool now respects settings for painting tools: showing the brush outline, snapping to dabs, and showing the paint tool cursor. UI: - Tools are now logically grouped in the toolbox by default. Users can customize the groups to their liking or disable this feature altogether in the Preferences dialog (Interface / Toolbox page). - New opt-out compact style for sliders with revamped interaction. The widget uses a narrower layout, and the different upper/lower-half behavior is gone. Instead, the behavior depends on the mouse button and modifier used: - left-click is used for absolute adjustment, - Shift + left-click + drag changes value in small increments, - Ctrl + left-click + drag changes value in large increments, - middle-click enables numeric input mode; - right-click enables numeric input mode and selects the value. - The "You can drop dockable dialogs here" message is gone from the toolbox for good. Instead, highlight dockable areas when a user starts dragging a dockable dialog, and intensify the highlight as the dialog goes over a dockable area. - Consolidate UI for merging down and anchoring layers: As they are both mutually exclusive and serve an almost identical purpose, the "Merge down" and "Anchor Layer" are given mutually exclusive visibility in menus, and the anchor button is replaced with a merge down button in the Layers dockable whenever there is no active floating selection. Modifier keys are available: - Shift: merge layer group - Ctrl: merge visible layers - Ctrl + Shift: merge visible layers from last used values Plugins: - In plug_in_compat.pdb, when wrapping an op node inside a graph, set the op node as the graph node's underlying operation. This allows gimp_gegl_apply_operation() to perform certain optimizations. - The Spyrogimp plugin now features a Visual tab where the inner mechanics of a spirograph is abstracted away, and you operate on amount of petals etc. The plugin now also allows saving a pattern as a path rather than rendering it to a layer as a bitmap. - Improve the loading speed for PSD files, mostly by eliminating excessive copies. Filters: - Don't disable gegl:color-to-alpha (which has "needs-alpha") when the drawable doesn't have an alpha channel, if one can be added. - Don't disable color-to-alpha for grayscale drawable, since the operation is applicable to grayscale images (in particular, it doesn't add color where there was none), and since GIMP no longer distinguishes between layers and channels according to the drawable format when updating the filters actions. Windows: - Installer: unofficial languages, ghostscript 9.50. - Installer: skip .debug files when they don't exist. - Installer: properly remove old icons on 32-bit installs and per-user installs. macOS: - Set required variables if it is running from Apple application bundle. - The macOS build now ships with the dashboard dock for displaying performance graphs. Updated translations: - British English, Catalan, Danish, French, German, Hungarian, Icelandic, Italian, Japanese, Polish, Russian, Spanish, Swedish, Turkish, Ukrainian.

Overview of Changes from GIMP 2.10.12 to GIMP 2.10.14 ===================================================== Core: - New "Selected areas continue outside the image" toggle option to the "Feather Selection" dialog. - New "Allow editing on non-visible layers" setting in Preferences to allow painting, transforming, and selecting on layers with toggled off visibility. - XCF loading a bit more resilient to corruption: it doesn't stop any more at the first layer or channel error; instead it tries to load more layers/channels to salvage as much data as possible from a corrupted XCF file. - In gimp:gradient, fix dithering to correspond to how we actually round float values to 8-bit. In particular, this avoids introducing noise when a component is fixed at 0 or 1 along a segment. - New "Show All" view mode allowing to show pixels outside the canvas boundary. - New "Show Canvas Boundary" option to render a dotted line around the canvas boundary. - New "Keep Padding in "Show All" Mode" option, also available as a default option via Preferences, to preserve the padding color instead of displaying the checkerboard. - Several features updated to react as expected when run out-of-canvas: color-picking, canvas grid, transform tools, bucket fill, and more. - Loaded images' pixel density will now default to 72 PPI when no explicit resolution information was stored in the imported file. Newly created images' default pixel density will continue to be based on the default image template (with value 300 PPI if it has not be changed), yet not loaded images anymore. 72 PPI is the common default in most software (and in standards such as Exif) so it makes sense we stick to it, only for loaded images. Tools: - Free Select tool: fast copy|cut-paste modifiers (Alt + Ctrl|Shift) are now working even when the selection is not committed. Starting a fast copy|cut-paste will automatically close the polygon and commit the selection, accelerating fast usage of free selections. - Foreground Select tool: new "Grayscale" Preview Mode. Also, a color selector for "Color" preview (original preview mode) now available, to select any color and opacity for the preview. - Add a new "Image" transform type to the transform tools, in addition to the existing "Layer", "Selection", and "Path" transform types. The "Image" mode transforms the entire image, rather than a single item. In tools with a preview, the preview shows the transformed image projection. The clipping mode controls how the canvas is clipped during the transform; in particular, the ADJUST clipping mode resizes the canvas to fit its transformed size. - In GimpFilterTool, add a new "clipping" option, which can be either Adjust or Clip. This option is controllable for layers, when there's no selection mask. When set to Adjust, which is used by default, the filter's output may extent past the drawable's boundary, and the drawable will be resized to match the output when committed. - Gradient tool: offset support in shaped gradients Plug-ins: - Simple 8-bit port of filters to GEGL: nl-filter, film, fractal-explorer, flame, blinds, jigsaw, gradient-flare, checkerboard, tile-small, curve-bend, sample-colorize, map-object, lighting, grid, despeckle, sphere-designer, contrast-retinex, hot, sparkle, cml-explorer, destripe, twain, animation-optimize, depth-merge, warp, imagemap, gimpressionist - Port of filters to GEGL with float support: van-gogh-lic. - Add color profile support for HEIF (only when libheif 1.4.0 is available). - TIFF import will now ask (in interactive mode) how to process unspecified TIFF channels: non-premultiplied (used to be the default) alpha, premultiplied alpha, or just import as generic channel. - HEIF export now improved with same profile logics as JPEG or WebP (it can actually export higher bit-depth data, so profile logics should be the one as in PNG, but we only support 8 bpc HEIF for the time being). - HEIF export dialog now has a "Save color profile" checkbox allowing to not export with a profile when needed (needs libheif 1.4.0 or higher). - PDF exporting: text layers in layer groups are now exported as proper text. - Cleaned up the file-dds GUI, removed the "Advanced" expander. - gimptool external tool now install plug-ins into subfolders (this is not mandatory in GIMP 2.10 yet, unlike future GIMP 3, but is already the recommended folder structure for plug-ins). - 3 procedures ("color-decode-ycocg", "color-decode-ycocg-scaled" and "color-decode-alpha-exp") removed from file-dds plug-in because they are hacks which should stay internal to the plug-in and are semantically wrong because colors in drawables are never in such formats. Filters: - New "Normal Map" filter to generate normal maps from height maps in the Generic section. - Replace old filters with GEGL operation counterparts: edge-neon (gegl:edge-neon), contrast-normalize (gegl:stretch-contrast), oilify (gegl:oilify) - Add gegl:bayer-matrix and gegl:linear-sinusoid to Filters -> Render -> Pattern. - Add gegl:newsprint to Filters -> Distorts. - Add gegl:mean-curvature-blur to Filters -> Blur. Performance: - Add an active-thread variable to the dashboard's misc group, showing the number of active worker threads. - Reduce time complexity of layer-group translation. When translating a layer group, avoid separately updating the original area of the child layers before translating them (as per the fix to issue #3484), as this results in quadratic time complexity w.r.t. to the maximal subgroup nesting level. Instead, simply defer the updating of the group's offset until *after* translating the child layers, so that their original area isn't clipped by the parent, while their new area is still properly updated even if the parent's size changes. User interface: - Many mnemonics added in various dialogs. - Add a gimp-rotate-image-arbitrary action, and a corresponding "Image -> Transform -> Arbitrary Rotation..." menu entry, which activates the rotate tool in image mode (similarly to the corresponding action for layers). - On Windows, minimized GIMP window is now deiconified when GIMP is run again (clicking its shortcut or otherwise). Preferences: - New "Swap compression" option: explicit control over the tile-swap compression algorithm in GEGL. "Best performance" is used by default, "Balanced", "Best compression", and "None" (disables compression) are available. Devel docs: - Update the libgimpconfig and libgimpbase docs. - Update docs with missing symbols and types. - New docs for structs and enums. Installers: - Install 64-bit Python on 64-bit Windows (until now, the installer used to install 32-bit Python for all architectures). - Windows installer now supports per-user install. Debugging: - New mnemonic-clashes tool to help looking for mnemonic clashes. Translations: - Basque, Brazilian Portuguese, British English, Catalan, Chinese (Taiwan), Croatian, Danish, Dutch, French, German, Greek, Hungarian, Icelandic, Indonesian, Italian, Latvian, Polish, Russian, Slovenian, Spanish, Swedish, Turkish.

Overview of Changes from GIMP 2.10.10 to GIMP 2.10.12 ===================================================== Core: - Add an "Incremental" option to the Dodge/Burn tool, which, similarly to the Paintbrush, Pencil, and Eraser tools, applies the effect incrementally as the pointer moves. - Curves now have a concept of smooth vs corner points: smooth points produce a smooth curve, while corner points produce a sharp curve (previously, all points were smooth). - Search the user font directory path on Windows (since Windows 10, non-admin users have the ability to install fonts). This is only a temporary hack until fontconfig adds proper upstream support: https://gitlab.freedesktop.org/fontconfig/fontconfig/issues/144 - In gimp_brush_core_get_paint_buffer(), when allocating a new paint buffer, clear the old buffer *before* allocating the new one, to reduce the amount of simultaneously allocated memory. - In GimpPaintbrush, avoid refilling the paint buffer at each dab if the paint color/pixmap hasn't changed, hence allowing faster painting in some specific cases. - Add hygon cpu detection and enable MMX/SSE support. - Add a GimpSymmetry::get_transform() virtual function and a corresponding gimp_symmetry_get_transform() function which return the brush transform corresponding to a given symmetry stroke in terms of the rotation angle and reflection flag (in contrast to gimp_symmetry_get_operation() which returns the same transforation in terms of a GeglNode). This allows us to simplify, fix (artifact bugs, etc.), and improve the painting-code performance for several symmetry painting cases. - New gimp-brush-pipe-spacing parasite set by core code to preserve GIH brush's spacing across reloads. - 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. Plug-ins: - Exported profile and data format strategy updated in several file plug-ins. * When not saving a profile, we always export as sRGB data, as most viewers would not display the image properly otherwise. * When saving a profile: * If a profile was manually assigned, we always export to the assigned format, hence pixel data is converted accordingly, whatever the work format. * If no profile was assigned: * If the export format support high-bit depth, we export the work format as-is. * If the export format is 8-bit max, we convert the work format to sRGB, except if the work format is 8-bit linear. The following plug-ins were updated: JPEG, PNG, TIFF and WebP. - TIFF plug-in now supports layer export. - Add accelerator on "Save color _profile" item in JPEG export so that all items in the dialog have keyboard accelerators. - Add a "Save color profile" checkbox in WebP export and remove the "Advanced Options" expander (all metadata and profile writing options are now directly visible). - Process cases of non-conformant TIFF file with extra channels while ExtraSamples is not set by assuming the first extra channel is a non-premultiplied alpha channel and outputting a warning. In the future, this should be updated further by a dialog asking what to do with the non-defined dialog (consider as premultiplied or non-premultiplied alpha channel, or just save as extra channels). Tools: - Add input/output spin-buttons to the Curves tool, which allow setting the selected point's coordinates numerically. When the image precision is greater than 8-bpc, use a 0.00-100.00 range for the point-coordinate spin-buttons instead of a 0-255 range. - In the Curves tool, allow changing the curve's point types (cf. new curve corner points in Core section). Corner points are displayed with a diamond shape instead of a circle. - Free Select tool now creates a selection as soon as the polygon is closed. This selection is updated when the polygon, or the relevant tool-options, change, similarly to GimpRectangleSelectTool. - Derive GimpEraser from GimpPaintbrush, instead of directly from GimpBrushCore. This allows GimpEraser to reuse the paint-buffer content across dabs, improving performance. - Allow moving an intersecting pair of guides with the Move tool. User interface: - In GimpCurveView, when dragging an existing curve point, don't immediately move the point to the cursor position upon button press, but rather move it relative to its current position as the cursor moves. This allows selecting a point without moving it, and adjusting its position more easily. - when the cursor hovers above a point in GimpCurveView, or when dragging a point, have the coordinate indicator show the point's position, rather than the cursor's. - In GimpCurveView, when holding down Ctrl while adding/dragging a point, snap the y-coordinate to the original curve (at the start of the drag). This is particularly useful for adding points along the curve. - In GimpDashboard, don't show legend for groups with no meter. - Add a tile-alloc-total variable to the dashboard's memory and misc groups, showing the total amount of memory used by the tile allocator. - Add a "Save Keyboard Shortcuts Now" button to the Configure Keyboard Shortcuts dialog. Installers: - Windows: enable InnoSetup "unofficial" translations. Otherwise we had a bunch of wasted work from our translators of several languages whose translations were never used in the installer. Translations: - 12 translations were updated: Catalan, Chinese, French, German, Hungarian, Indonesian, Italian, Polish, Russian, Spanish, Swedish and Turkish. Overview of Changes from GIMP 2.10.8 to GIMP 2.10.10 ==================================================== Core: - Add gimp-scratch allocator, a fast memory allocator (on the order of magnitude of alloca()), suitable for small (up to a few megabytes), short-lived (usually, bound to the current stack-frame) allocations. Unlike alloca(), gimp-scratch doesn't use the stack, and is therefore safer, and will also serve bigger requests, by falling-back to malloc(). - In gimp_drawable_transform_buffer_affine(), avoid modifying the clipping mode when transforming layer masks, since this function is used (among other things) to transform layer masks together with their layer, in which case they should use the same clipping mode as the layer. This fixes a regression introduced by commit 2ae823ba, causing layer masks to be transformed with a mismatched clipping mode during layer transforms, leading to discrepancies between the transformed layer and the transformed mask. - Moved swap/cache and temporary files out the GIMP user config dir and added new config file substitutions ${gimp_cache_dir} and ${gimp_temp_dir}. - Pass the GEGL tile-cache size, swap path, and thread-count to plug-ins as part of their config, and have libgimp set the plug-in's GeglConfig accordingly upon initialization. - Layer groups are now rendered in bigger chunks rather than tile-by-tile (which used to pretty much eliminate multithreading for groups), which improves the rendering speed. - Make saving/exporting files more robust to errors. In particular if an error occurs during the process (be it a bug, a memory error, or anything else), GIMP won't overwrite anymore any existing file with incomplete contents, so that you won't end up with no valid files at all. - Fix a regression on support of various graphics tablet. - Remove the "Edit -> Fade..." feature: it makes GIMP use two buffers instead of one (east into system resources), it's broken in 2.10, and we can make the UX better for filters. - New generic canvas modifier 'Alt + middle click' allowing to pick layers by clicking on pixels. The available layers will be looped through (starting from the upper one) while Alt key is hold and the picked layer name will be temporarily displayed in the status bar. - When clearing a channel, do nothing if the channel is already empty; otherwise, align the cleared rectangle to the channel buffer's tile grid, so that all affected tiles are dropped, rather than zeroed. Furthermore, only update the affected region of the channel. - Brush and pattern saving logics has been moved to core code (instead of plug-in). - Clipboard brushes and pattern can now be duplicated. - Parametric brushes are now 32-bit float to avoid posterization on large brushes. Note: raster brushes are still 8-bit and plug-ins only have access to 8-bit versions of high-precision brushes/patterns. New API will be required to handle high-precision data. - On-canvas preview while editing a color in the colormap of an indexed image. User interface: - Enabled HiDPI/Retina support for the GTK2/OSX build, fixes blurry icons. - Add a tooltip to the "better compression" checkbox in save dialog to make it clearer it does not mean that the file size is necessarily smaller in every cases. In particular some best/worst case are possible when an algorithm less efficient in general may end up better on a particular image. - Add basic support for cursors with a scale factor of 2 for HiDPI (artwork to be updated). - Foreground and background color icons, as well as color history will now display out-of-gamut warning on indexed images for colors outside of the palette, as well as on grayscale images, for non-gray colors. - Pack color picker and hexadecimal entry on same line in Color dock. - Add an "Open as Image" button to the brushes dialog. Usability: - Attempting to transform locked layers or paint on them now results in blinking around the status bar (where the warning message is displayed) and around the toolbar where lock toggles are. The same applies to attempting to move a selection where there is none — GIMP will blink around the toolbar where the moving target (layer, selection, path) is chosen. - GIMP now allows selecting default export file type for new projects. The choice is limited to PNG, JPEG, WebP, PSD, ORA, TIFF, BMP. - GimpSpinScale widget now has an optional feature to constrain the value to integer when dragging with a pointer (even if the scale allows for fractional numbers), set with new function gimp_spin_scale_set_constrain_drag(). This is useful for settings where fractional numbers are technically possible, yet most common use case are with integers (such as pixel sizes, angles in degrees, etc.) so you want the easy interface to be constrained. Fractional numbers are still settable, for instance by keyboard edit; and arrow incrementation won't drop fraction parts. This is currently only activated for brush options in paint tools. Tools: - In scale tool, scale around center even when using numeric input. - New algorithm in the Bucket Fill tool when selecting the affected area "Fill by line art detection", based off the G'Mic algorithm for "smart colorization": https://hal.archives-ouvertes.fr/hal-01891876 In a few words, it identifies painted pixels (either based on grayscale or opacity values) and tries to close line arts to allow filling even with not perfectly closed zones; the second step of the algorithm will flood the colors under line art pixels to prevent "holes" in the filling. It is possible to control a max size (in pixels) for the flooding, as well as max length of closing segments and splines. - The Bucket Fill tool got new interaction allowing to hold the click and move the mouse to fill based on several seed zones (for "Fill by line art detection" as well as "Fill similar colors"). You can now cancel the fill in progress with right click as in other tools. - The Bucket Fill tool now allows color picking with ctrl-click, same as every painting tool. It will pick either the foreground or background color depending on the selected Fill Type. The ctrl-alt modifier combination is also possible to pick the non-Fill Type color. - In the Bucket Fill tool, the Alt modifier will now switch to "FG color fill" when "Pattern fill" was set (instead of doing nothing). - In the Unified Transform tool, default to preserving aspect ratio when scaling up or down. - In the Healing tool, "Sample merged" now also work for the target pixels, allowing to draw in empty layers. - Selection by color is now parallelized, hence improving speed of the Select by Color tool (and any other processing which may share this piece of code now or in the future). - Add "Constrain handles" and "Around center" options to the perspective-transform tool's GUI, which are similar to the corresponding options of the unified-transform tool. - Improve color picking on indexed image to always select an indexed color corresponding to the picked pixel in the colormap. Plug-ins: - file-pdf-save GUI now clearly indicates the order the layers will be used to make multi-page PDFs. - Add DDS loading/exporting plug-in originally developed by Shawn Kirst and Arne Reuter. - Rename the Guillotine plug-in to Slice Using Guides. - Add a new option saving a color profile when exporting PNG, JPEG, TIFF. Always save it when exporting to PSD. - Remove the "Advanced" expanders from the PNG and TIFF export dialogs. - Full rewrite of the Spyrogimp plug-in with much more options and better interaction. - Indexed TIFF with alpha channel now supported. Filters: - Add on-canvas GUI (simple lines) for circular, linear, and zoom motion blur. Help: - Link to the bugtracker directly from the Help menu, also link to the wiki and the roadmap. Remove the link to currently disabled registry.gimp.org. Installers: - Windows: proper fix for libthai to stop GIMP from crashing in the Thai locale. Translations: - Czech, Danish, French, Italian, Japanese, Marathi, Polish, Russian, Spanish, Swedish, Ukrainian. Build: - Bumping GTK+ dependency to the micro update GTK+ 2.24.32 to handle several bugs on Windows (broken shortcuts on non-latin layouts and broken vector icons). Overview of Changes from GIMP 2.10.6 to GIMP 2.10.8 =================================================== Core: - Use adaptive chunk size in GimpProjection when rendering the projection asynchronously, rather than using a fixed chunk size. This provides a better trade-off between throughput and responsiveness dynamically, based on how fast the processing is. - Add xyY color space to the color spaces for sampling colors. Tools: - In all selection tools, show error on attempt to subtract-from/intersect-with empty selection. - Fix text along path not working with vertical text. - Fix Text tool's frame position when undoing a move operation. - Streamline Text tool's drawing blocking/unblocking logic. - When moving a text layer using the text tool (through alt+drag), don't change the layer's box mode to "fixed", which is unnecessary, since the layer's size isn't affected. - Transform and deformation operations now maintain color for fully transparent pixels, making unerase and curves manipulation of alpha channel more reliable. - All transform tools now apply changes when you save or export/overwrite an image without pressing Enter first to confirm changes. - Heal, Dodge/Burn, Smudge, and Convolve tools now adjust the processed buffer and mask_buffer regions according to the changes made to the application region, as calculated by intersecting it with the drawable and mask extents. This fixes wrong application position when painting on a drawable whose origin is above/to the left of the image's origin, and there's a selection active. - New type of gradient interpolation called 'Step' for making multi-color hard-edge gradient fills. Plug-ins: - Port all plug-ins to the new iterator API in GEGL. - Improve automatic detection of HEIC/HEIF files. - Improve RawTherapee discovery by looking up registry key (should become useful with RawTherapee 5.5 and more). Usability and UI: - Compatibility information in the Save dialog is now more understandable. The minimum GIMP version for the XCF file is always written down when it is GIMP 2.8 or over. The list of features warranting the minimum version is now listed in an expander container rather than as tooltip, which makes it more discoverable. The warning on compression is now displayed as its own text under the checkbox and not as additional text to the minimum GIMP version label. - In all themes, fix the color of selected text, while editing a tree-view's item text (such as when renaming a layer), by overriding tree-view specific styling with the global text-entry style, for nested text entries inside tree-views. The text would previously use the same color as the selection background, making it unreadable. - Add option in the Windows menu to hide the image tab bar. CLI: - New self-explanatory --enable-win32-debug-console CLI option Debugging: - New GimpBacktrace API provides an interface for creating and traversing multi-threaded backtraces, as well as querying symbol information. Backends are available for Linux and Windows. - Performance log recording now available in the Dashboard dock. The log contains a series of samples of the dashboard variables, as well as the full program backtrace, when available. As such, it essentially acts as a built-in profiler, which allows us to correlate program execution with the information available through the Dashboard. - New performance-log-expand.py tool decodes a delta-encoded performance log by expanding the deltas, producing a log where each sample (and other relevant elements) contain complete information. The structure of expanded logs is identical to that of delta-encoded logs, the expanded log simply has no deltas. - New performance-log-resolve.py tool resolves symbol information in backtraces. The logs produced by GIMP only specify the program counter at each stack frame, providing an address-map to map program-counter addresses to actual symbols separately. This tool looks up each program-counter address in the address map, incorporating the relevant symbol information directly into the backtrace. - New performance-log-deduce.py tool that statistically deduces the correct thread states based on backtrace address frequency, fixing local inaccuracies. - New performance-log-viewer.py tool that is a viewer for GIMP performance logs, with a sample-selection area at the top and an information area at the bottom. The sample-selection area visualizes the sampled variables and markers using a simultaneous set of plots, and displays the currently selected samples. The information area shows global information stored in the log, as well as information specific to the currently selected samples, including variable listing and statistics, full backtrace, and profile/call-graph information. Translations: - Updated translations: Danish, Dutch, Finnish, German, Hungarian, Italian, Marathi, Polish, Portuguese (Brazil), Russian, Spanish, Swedish, Ukrainian. Overview of Changes from GIMP 2.10.4 to GIMP 2.10.6 =================================================== Core: - Render drawable previews asynchronously. - Merge the file view filter and file format lists in GimpFileDialog. The presence of 2 lists was very confusing. - DLL search priority is now updated before running a plug-in on Windows, depending on the executable bitness. This gets rid of one of the last remnant of DLL hell in GIMP, which was when running 32-bit plug-ins from a 64-bit build of GIMP. Filters: - New "Little Planet" (gegl:stereographic-projection) filter. - New "Long Shadow" (gegl:long-shadow) filter. Tools: - Halt the Measure tool after straightening. - Add an "orientation" option to the measure tool, corresponding to the "orientation" property of GimpToolCompass (i.e., it controls the orientation against which the angle is measured, when not in 3- point mode.) The orientation is "auto" by default, so that the angle is always <= 45 deg. Note that the "orientation" option affects the tool's "straighten" function, so that the layer is rotated toward the current orientation. - Text layers can now represent vertical texts, with 4 variants: left-to-right and right-to-left lines, and forcing all characters to be upright or following Unicode's vertical orientation property. See also: * https://www.unicode.org/reports/tr50/ * http://www.unicode.org/Public/UCD/latest/ucd/VerticalOrientation.txt User Interface: - The Dashboard dockable dialog now has an "async" field to the dashboard's "misc" group, showing the number of async operations currently in the "running" state. - New Preferences option to enable/disable layer-group previews, since these can get quite time-expensive. Translations: - New language: Marathi - 12 translations were updated: Brazilian Portuguese, Dutch, French, German, Greek, Italian, Latvian, Polish, Romanian, Slovenian, Spanish, Swedish. Build: - Add --with-win32-32bit-dll-folder configuration option to override the folder where 32-bit versions of DLL will be installed (default: 32/bin/). - Install all plug-ins in their own directories. Unlike on master, this is not mandatory to do so, but it would protect our core plug-ins against any DLL installed directly under plug-ins/ by third-party plug-ins (cf. Windows DLL hell). Overview of Changes from GIMP 2.10.2 to GIMP 2.10.4 =================================================== Core: - Remove gimp_display_shell_draw_background() and all clipping hacks for drawing the canvas background. This optimizes away one entire step of drawing of image size, for each expose. - Font loading does not block startup anymore. Only consequence is that the Text tool may not be usable immediately if fonts are not fully loaded yet (and will output an appropriate error if you do so). All non-text related activities can be performed right away. - Change of the URL from bugzilla to gitlab where appropriate. - New tool option manager to better keep track of user context and paint options in a consistent manner. User Interface: - The Dashboard dockable dialog now has a 'Memory' group that shows memory-usage information: the currently used memory size, the available physical memory size, and the total physical memory size. It can also show the tile-cache size, for comparison against the other memory stats. Note that the upper-bound of the meter is the physical memory size, so the memory usage may be over 100% when GIMP uses the swap. - The Dashboard dockable dialog now has "read" and "written" fields in the dashboard swap group, which report the total amount of data read-from/written-to the tile swap, respetively. Additionally, the swap busy indicator (used as the meter's LED) has been improved, so that it's active whenever data has been read-from/written-to the swap during the last sampling interval, rather than at the point of sampling. - Fonts can now be tagged. The user interface is the same as for brushes, patterns etc. - Some icons fixed: larger spacing between broken chains and gimp-tool-ellipse-select made symmetrical. Usability: - When a plug-in cannot be applied to an image because of mismatch in image types (e.g. layer has no alpha or image is greyscale), GIMP now displays a message listing supported image types for this plug-in. Tools: - The Measurement tool now has an "Auto straighten" option allowing to rotate the active drawable (layer, channel…) so that the measurement line is used as horizon. As other transform tools, the feature will work on linked drawables as well. - The Smudge tool now paints correctly on images with a color profile other than the GIMP's built-in one. Build: - Installer: set compatibility options to run Python plugins in HiDPI-aware mode. - Put back compatibility DLLs for really old plugins. - Install binary tool `gimp-test-clipboard` on the system to allow people to help us debug clipboard bugs. - --enable-bundled-mypaint-brushes renamed --enable-relocatable-bundle and also make WMF fonts looked up on the runtime prefix of GIMP (instead of the build-time path) when this build option was set. Plug-ins: - gimptool-2.0 binary now accepts source files with non-standard extensions if it can try to guess appropriate language from the compiler being used. It will also properly quote arguments for shell usage. - Run explicitly Python 2 as Python plug-in interpreter to prevent breakage on systems where Python 3 is the default. - raw_input()'s argument in Python console is now optional, and input() support has been added. File Formats: - The PSD loader now provides an option to load "merged", pre-composited version of the images that becomes available when a PSD file was saved with "Maximize Compatibility" option enabled in Photoshop. This is useful when loading PSD files that use features that GIMP doesn't currently support, and therefore can't render correctly, such as adjustment layers. When loading the merged image version, we avoid loading certain additional data from the file, such as channels, paths, and guides, while still loading metadata. This option is currently exposed as an additional file type ("Photoshop image (merged)"), which has to be explicitly selected from the file-type list when opening the image. - Embedding GIMP's built-in sRGB color profile to exported files is now optional. The default choice can be set in the Preferences dialog. Translations: - Updated translations: Catalan, Czech, Danish, Dutch, Finnish, Greek, Hungarian, Italian, Latvian, Polish, Romanian, Russian, Spanish, Swedish, Ukrainian. Overview of Changes from GIMP 2.10.0 to GIMP 2.10.2 =================================================== Core: - Discard fonts which fail to load and popup an info dialog to allow people debug their fonts. - New API to suppress updates in UI until plug-ins are done introducing changes. - New API to calculate histograms in separate threads, with possible further extension to handle similar cases elsewhere in GIMP. - Tool options are now properly saved and reloaded per-device at startup. Plug-ins: - New plug-in for importing and exporting HEIF images. - Enable visibility of rasterized vector layer from PSD. - Single-window screenshots in Windows fixed to correctly snap a window even when it is partly off-screen or covered by another window or when display scaling is not set to 100%. Filters: - New Spherize filter to wrap an image around a spherical cap - New Recursive Transform filter to create Droste effect. Usability: - Warn users, when alpha-only painting has no effect. E.g. when target drawable doesn't have an alpha channel, or the alpha channel is locked. - Make the splash texts dynamic, so they are larger on larger splashes. - Mention pressing Enter to complete Foreground selection in the status bar. - Make sure that clicking outside any selection prevents Rectangle Select and Ellipse Select tools from creating empty selections. - Improve mouse wheel zooming behavior to keep the same point centered under the pointer even if the image is completely visible in the canvas. - Add "View -> Center Image in Window" (Shift+J) as a quick way to center the image at any zoom level. Translations: - Updated translations: Catalan, Danish, Dutch, French, German, Greek, Hungarian, Icelandic, Italian, Latvian, Polish, Russian, Spanish, Swedish, Ukrainian. - New translation of Windows installer: Chinese (Taiwan) Build: - Add a --with-bug-report-url configure option allowing packagers to set the address of their own bug tracker. This address will be the one opened by the debug dialog for reporting bugs. - Add a flatpak manifest for the gtk3-port branch. - Remove the possibility to disable script-fu. - Add a --with-icc-directory configure option to customize the color profile directory. By default, it is set to the common path /usr/share/color/icc. Documentation: - Updating the description of the XCF format "devel-docs/xcf.txt", for third-party readers wishing to support GIMP 2.10 XCF files. - Add documentation skeletons for all enums in libgimpbase/, there is much room for improvement.
