Software-update: GIMP 2.9.4

Door , 7 reacties, submitter: Rafe, bron: The Gimp Team

The GIMP logo (75 pix)De tweede ontwikkelversie uit de 2.9-serie van het opensource-fotobewerkingsprogramma The Gimp is uitgekomen. De naam GIMP is een afkorting voor 'GNU Image Manipulation Program'. De software is beschikbaar voor diverse besturingssystemen, waaronder Windows, FreeBSD, Linux, OS X en Solaris. De broncode is al op te halen, binaries voor de verschillende besturingssystemen volgen spoedig. In versie 2.9 is onder meer de GEGL-image processing engine nog verder geïntegreerd, kan het canvas worden geroteerd en treffen we diverse nieuwe en verbeterde tools aan. De complete release notes voor deze uitgave zien er als volgt uit:

GIMP 2.9.4 Released

We have just released the second development version of GIMP in the 2.9.x series. After half a year in the works, GIMP 2.9.4 delivers a massive update: revamped look and feel, major improvements in color management, as well as production-ready MyPaint Brush tool, symmetric painting, and split preview for GEGL-based filters. Additionally, dozens of bugs have been fixed, and numerous small improvements have been applied.

GIMP 2.9.4 is quite reliable for production work, but there are still loose ends to tie, which is why releasing stable v2.10 will take a while. Please refer to the Roadmap for the list of major pending changes.

Revamped User Interface and Usability Changes

The new version features several new themes by Benoit Touchette in various shades of gray: Lighter, Light, Gray, Dark, Darker. The system theme has been preserved for users who prefer a completely consistent look of user interfaces across all desktop applications.

Note that we still consider this feature a work in progress, as dark themes still need some fine-tuning (especially regarding the color of inactive menu items).

The new UI themes are accompanied by symbolic icons originally created by Barbara Muraus and Jakub Steiner, and heavily updated and completed by Klaus Staedtler. The existing icon theme from past releases of GIMP has also been preserved, and users can freely switch between available icon themes and easily add their own ones.

Note that themes and icon themes are now separate: you can easily mix your favorite UI with various icon sets. Also since most 2.8 themes would end up broken in 2.9.x, themes are not migrated from GIMP < 2.9. Users who want custom themes will have to install ones specifically made for GIMP 2.9/2.10.

All work on icons by Klaus Staedtler is made on vector (SVG) images, which should allow better support for HiDPI displays (also commonly known as Retina) soon. Vector icons are an experimental feature, available after using the --enable-vector-icons build configure option. Note that this option does not allow HiDPI support at this time.

We cleaned the Preferences dialog a little and reordered options in a more logical manner. The Color Management page was redesigned following both internal and user-visible changes in relevant parts of GIMP (see below), and the Snap Distance options have been moved to a dedicated Snapping page.

Additionally, it is now possible to configure the size of undo step previews in the Undo dialog via the Preferences dialog, which was previously only possible by manually editing GIMP’s configuration file GIMP’s configuration file, by a complete oversight on our part.

The startup splash screen now features a pulsing progress bar to indicate that GIMP is not frozen. This, as well as initializing fontconfig in the background (also a new feature in 2.9.4), is meant to address a common issue where rebuilding the fonts cache (or building it for the first time) can take a lot of time hence making an impression that GIMP freezes at startup. We acknowledge that this is a workaround. Fixing the actual reason involves hacking on fontconfig. If you are interested, there is a bug report on that.

Color Management Improvements

The color management implementation got a complete overhaul in this version of GIMP. Instead of being a pluggable module, it is now a core feature. Moreover, we added an abstraction layer that makes GIMP less dependent on LittleCMS. This means that in the future GIMP could use native APIs on Windows and OS X, and/or use OCIO.

For now, it has helped us to clean up the code a lot and introduce a clean implementation of color management to various bits of GIMP such as: previews for color swatches and gradients, patterns, various color widgets (including the drag-and-drop color widget), the Color Picker tool, layer and image preview etc. The only unmanaged bit for now is the color widget in the Script-Fu and Python-Fu plug-ins. Moreover, GIMP will track which monitor the widget is currently on (different monitors would have different ICC profiles assigned to them) and color-correct it accordingly.

Grayscale images are first class citizens in GIMP once again: since v2.9.4, GIMP can color-manage them as well.

Since GIMP currently relies on sRGB (this is bound to change in future versions of GIMP), we decided to expose that in the user interface. So currently GIMP has an option called ‘Color-manage this image’ in two places: the New Image dialog and the Image > Color Management submenu. What it means is that instead of taking into consideration the ICC profile embedded into an image (whichever profile it is) it will just treat everything as sRGB. Please note that we are likely to reword the option to make it even more explicit about what it does.

Additionally, there’s now a View > Color Management submenu where you can enable and control softproofing.

The Color Management section of the Preferences dialog has been reorganized to reflect recent changes and provide more consistent wording of options.

Since color management comes with a speed penalty (at least with LittleCMS), there’s a new option that enables you to choose either better color fidelity of faster processing depending on the kind of work you usually do.

Among smaller changes there’s a new Image > Color Management > Save Color Profile to File... command that does exactly what it says: it dumps an embedded ICC profile to disk as a file. Note that copyright restrictions on ICC profiles may apply, so please be careful.


GIMP now keeps track of all GEGL-based filters that you used within one session and allows re-running them via the Filters > Recently Used submenu, just like old GIMP plug-ins.

The Posterize and Desaturate color tools have been converted to regular GEGL-based filters, and both the Tile and Pagecurl filters have been converted to use GEGL buffers. A quite popular “photographic” Highpass filter commonly used for enhancing details was added to the Filters > Enhance submenu.

A way more noticeable new feature, however, is split preview for GEGL-based filters. You can compare before/after versions right on canvas and move a “curtain” around to see more of “before” or “after”, and swap their positions (Shift + click on the guide). You can also switch between vertical and horizontal division (Ctrl + click).

darktable as Raw Processing Plug-in

On Linux, GIMP is now capable of using darktable for pre-processing raw images from DSLRs (Canon CR2, Nikon NEF etc.). darktable is an amazing project whose developers stick around at our IRC channel and even contribute to GIMP (most recently, they added reading various metadata from EXR files).

Note that the file-darktable plug-in is activated only when darktable is built with Lua support. Make sure your build of darktable for Linux is feature-complete.

It is still possible to use other raw development plug-ins like UFRaw. For cases when multiple plug-ins are installed in your system, we intend to add a preference option.


The code for capturing screenshots has undergone a major reorganization. It’s now split into a front-end and several back-ends specific for Windows, OS X, Wayland and (Linux and UNIX systems).

While there are no immediate user-visible changes, this reorganization will greatly simplify further improvements, hence improving user experience on different operating systems.


MyPaint Brush Tool

The new MyPaint Brush tool is now enabled by default. Daniel Sabo and Michael Natterer improved its performance and made MyPaint brushes available via an already familiar dockable dialog interface, with previews and tagging.

Jehan Pagès collaborated with the MyPaint team: he ported libmypaint to autotools, allowing, in particular, standard builds on all platforms, and work is being done to turn the default brushes into a separately shipped package.

Symmetry Painting

Another major new feature is symmetric painting mode, also developed by Jehan Pagès with financial support from the GIMP community. It can be activated through the new Symmetry Painting dockable dialog and allows to use all paint tools with various symmetries (mirror, mandala, tiling…).

  • “Mirror” allows to paint with horizontal, vertical (axial), and/or central symmetry. The symmetry guides can be placed anywhere on canvas.
  • “Mandala” is a rotational symmetry of any order. The center can be placed anywhere on canvas.
  • “Tiling” is a translational symmetry, which can be finite (with a maximum of strokes) or infinite. In the latter case, it is the perfect tool to create patterns or seamless tiles, with instant rendering of what it will look like, at painting time.

Tool Options

The mouse scroll-wheel action mappings have been improved, allowing, in combination with various modifiers, to do useful things on the currently selected tool’s options:

  • Alt + Mousewheel: opacity increase/decrease;
  • Shift + Primary + Mousewheel: aspect increase/decrease;
  • Shift + Alt + Mousewheel: angle increase/decrease;
  • Primary + Alt + Mousewheel: size increase/decrease;
  • Shift + Primary + Alt + Mousewheel: spacing increase/decrease.

Note: the Primary modifier is usually Ctrl or Cmd, depending on your platform.


For cases when your selection has a lot of small unselected regions, you can now use the Select > Remove Holes command.

The Select > Border... dialog now provides several border style options: hard, smooth, and feathered. Feathered creates a selection which goes gradually from 1 to 0 the farther you get from the middle of the border. Smooth preserves partial selection (antialiasing) along the edges of the selection.

Better Tools

The Fuzzy Select and Bucket Fill tools got a new feature for selecting/filling diagonally neighboring pixels.

The Blend tool got shapeburst fills resurrected, and allows the placement of their handles on the canvas, outside of the image area. Additionally, the Blend tool now displays its progress thanks to a new GEGL feature available in several GEGL operations including gegl:distance-transform.

The Text tool now fully supports advanced input methods for CJK and other non-western languages. Minimal support already existed, but the pre-edit text was displayed in a floating pop-up instead of inline, within the text tool box, and without any preview styling. It is now displayed just as expected, depending on your platform and Input Method Engine. Several input method-related bugs and crashes have also been fixed.

Batch Processing on Command Line

A new macro with-files is now available in order to easily process multiple files through GIMP from the command line, which was a much awaited feature.

For instance, if you want to invert the colors of all PNG images in the current folder, then save them as JPEG, you could run the following from the command line:

gimp -i -b '(with-files "*.png"
                (gimp-invert layer)
                (gimp-file-save 1 image layer
                    (string-append basename ".jpg")
                    (string-append basename ".jpg")
            (gimp-quit 0)'

Note: the name of the macro may change before the release of v2.10.

Email Plug-in Resurrected

The File > Send by email… dialog will open your default email client with an attached copy of the current image, to share your work-in-progress with a single click. This is available only on operating systems with xdg-email (likely GNU/Linux, BSD only).

The original implementation using sendmail is also available. Yet since it requires a properly configured sendmail, which is not common on desktop machines, the explicit --with-sendmail option has to be set at build time to replace the xdg-email implementation.

Wijzig sortering
En welke afbeelding wordt er dan bij gezet, één van 2.8.10. Terwijl er nu juist UI veranderingen zijn die wel baat zouden hebben van een afbeelding van de correcte versie.

De pagina van gimp 2.9.4 is hier, deze heeft de afbeeldingen wel.

Toch fijn dat er nog een goede opensource Photoshop vervanger is!
"As usual, the GIMP team is small yet as dedicated as ever: more than a third of the commits have been done by Michael Natterer (514), the next biggest contributors being Jehan Pagès (192) and Klaus Staedtler (187). The three of them represent 66% of all commits."

Dit vind ik echter een weinig florissant gegeven voor een OSS project.
Wat ik wel goed vind om te zien dat duidelijk de samenwerking gezocht lijkt te worden met de MyPaint brush, Darktable en OCIO.
Dat is inderdaad wel jammer, en verklaart waarom er (voor de afstandelijke observator) weinig tempo in lijkt te zitten. (Een poos geleden waren er geloof ik nog 7 vaste developers).
Mogelijk vereist het naast programmeren ook foto-technische kennis waardoor het moeilijk is nieuwe mensen in te werken?

Een van de veranderingen van 2.10 naar 3.0 is de port naar GTK3. Ik ben geen programmeur, maar het lijkt me dat daarin veel dezelfde soort veranderingen in moeten plaatsvinden, die geschikt zouden kunnen zijn voor een "Easy Hacks" list.
Hopelijk maken ze daar gebruik van om nieuwe programmeurs aan te trekken.
Als alternatief heb je ook nog de gratis paint.NET met expansion packs.

En zelfs portable, dus altijd en overal direct te starten vanaf bijv. een USB-stick :-)
Lijkt erop dat dit het jaar van de (cross-desktop) Floss Foto software word. Eerst Krita 3 en Digikam 5, nu GIMP 2.9.4, (misschien later dit jaar eindelijk 9.10?), en LO Draw wordt ook onder handen genomen dit jaar.

Op dit item kan niet meer gereageerd worden.
