Krita is een programma waarmee digitale tekeningen kunnen worden bewerkt en gecreëerd, en kan overweg met zowel bitmap- als verctorafbeeldingen. Het programma is onderdeel van Calligra Suite en wordt ontwikkeld door het KDE-team, maar werkt ook prima onder Gnome of XFCE. Daarnaast is er een download voor Windows en is er een versie voor OS X in ontwikkeling. Zojuist is versie 2.8 uitgekomen en wat daar allemaal in veranderd is, kan hieronder worden gevonden.
Windows version
Krita 2.8 will be the first stable Krita release for Windows. We have been making experimental builds for Windows for about a year now, and a lot of testers helped us to stabilize it. While this is not really a new feature for the Linux user, the step and the work on it was so huge that it does merit the 1st rank in this feature list! Most work on the Windows port has been done by KO GmbH, in cooperation with Intel.
Better tablet support:
Krita has relied on Qt's graphics tablet support since Krita 2.0. We consciously dropped our own X11-level code in favour of the cross-platform API that Qt offered. And apart from the lack of support for non-Wacom tablets, this was mostly enough on X11. On Windows, the story was different, and we were confronted by problems with offsets, bad performance, no support for tablets with built-in digitizers like the Lenovo Helix.
So, with leaden shoes, we decided to dive in, and do our own tablet support. This was mostly done by Dmitry Kazakov during a week-long visit to Deventer, sponsored by the Krita Foundation. We now have our own code on X11 and Windows, though still based on Qt's example. Drawing is much, much smoother because we can process much more information and issues with offsets are gone.
New high-quality scaling mode for the OpenGL canvas
Krita was one of the first painting applications with support of OpenGL to render the image. And while OpenGL gave us awesome performance when rotating, panning or zooming, rendering quality was lacking a bit.
That's because by default, OpenGL scales using some fast, but inaccurate algorithms. Basically, the user had the choice between grainy and blurry rendering.
Again, as part of his sponsored work by the Krita Foundation, Dmitry took the lead and implemented a high-quality scaling algorithm on top of the modern, shader-based architecture Boudewijn had originally implemented.
The result? Even at small zoom levels, the high-quality scaling option gives beautiful and fast results.
Krita Gemini
On Linux, the Krita Sketch user interface is now bundled with Krita 2.8, and users can switch from one interface to another. Krita Sketch and Krita Gemini were developed by KO GmbH together with Intel. On Windows, Krita Gemini will be available through Valve's Steam platform.
Wrap Around mode
The Wrap Around mode (activate it with the W key, or in View > Wrap around mode) tiles the artwork on the canvas border for easy creation of tiled textures. It is only visualized in OpenGL mode (Settings > Configure Krita > Display).
New default presets, better tagging system
Krita 2.8 offer a new set of brush presets, with new icons following standards. Here is a screenshot with a sample of them.
Additionally, now It is easier and faster to assign tags to resources -- with a single right click.
Layer-picker
Directly select a layer by pressing the 'R' key and clicking with mouse/stylus on the canvas.
Custom transparency checkboxes:
Transparency checkboxes represent the transparent colors. Now the colors and size of the checkboxes are configurable: You can change it in Settings > Preferences > Transparency Checkboxes.
New palette docker
It’s now easier to switch palettes with the Palette docker. Adding and removing a color can be performed directly on the docker. A set of new palette presets made by talented authors are now also bundled with Krita by default. You can display the Palette docker via: Setting > Docker > Palette.
Pseudo Infinite canvas
If you scroll the canvas a lot in one direction, you’ll notice a big button appearing with an arrow on it on the border of the screen A single click on this big button will extend the canvas automatically in this direction.
This feature will help you to focus on drawing and never worry about the drawing surface available.
Additional options for the crop tool
The crop tool can now ‘grow’ (you can crop a document outside the canvas limit and extend the canvas) and also get decorations (third guidelines, middle crosshair).
Better color pickers
The color pickers get new icons and more options.
- Ctrl + LeftClick --- Pick from merged image to Fg color
- Ctrl + Alt + LeftClick --- Pick from current layer to Fg color
- Ctrl + RightClick --- Pick from merged image to Bg color
- Ctrl + Alt + RightClick --- Pick from current layer to Bg color
You can change the shortcuts (like Alt) for the Color pickers in the Settings > Configure Krita > Canvas Input Settings and unfold ‘Alternate Invocation’.
Development: Dmitry Kazakov, icons: David Revoy
New Color balance filter
Color balance changes the overall colors of an artwork via sliders and is used for color correction. It’s an ideal filter to give an extra mood to your artwork (warmer, cooler) or enhance black and white studies. You can find the filter here: Filter > Adjust > Color balance (Ctrl+B)
Initial support for G'mic
Use hundreds of famous Gmic filters directly in Krita. It’s a first implementation, and still experimental and unstable. Also, it does not yet take the selection into account and doesn't show a preview yet.
You can find the feature under the menu: Layer > Apply Gmic actions.
Clone array tool
This new feature creates a number of clones of the current layer so you can paint on it as if the tiles were repeated. The feature is convenient for the creation of isometric tiles.
You can find the feature in Layer > Clone Array
Note that, ‘Clone layers’ child can be moved independently from the parent layer with the move tool. You can clone any base layer, and position them to your liking ; they keep the dynamic properties to the live clone.
More custom shortcuts
Krita gets a new panel in the preferences (Setting > Configure Krita > Canvas Input Settings) to offer you the possibility to customize all related canvas shortcuts. That means: all the zoom- and color picker keys are configurable now.
More compact, better looking
A lot of work was done to make the Krita 2.8 user interface more compact, and dim the saturation of the icons to let the user focus on the canvas.
Other new Features:
- Make it possible to copy the projection of a group layer
- Make it possible to drop images on the startup page
- Isolate layer or mask: right-click on the layer or mask, select "isolate" and temporarily work only on that layer or mask.
- Make it possible to load ACT palette files
- Make the channel docker work on the image, not the individual layer
- Add a wraparound layer move mode
Removed Features
- OpenShiva filter and generator scripting language. This is replaced by the G'Mic plugin.

- Make the fill layer command obey the alpha lock switch
- Make the PSD import filter ignore malformed resource blocks

- Make the fill tool obey the layer alpha lock state
- Rework the brush outline cursor and add a combined brush outline and dot or crosshair cursor mode. Brush outlines now also behave sensibly with very big and very small brushes.
