Krita(/ˈkriːtə/KREE-tə)[6]is afree and open-sourceraster graphics editordesigned primarily fordigital artand2D animation.Originally created forLinux,the software also runs onWindows,macOS,Haiku,Android,andChromeOS,and features anOpenGL-accelerated canvas,colour managementsupport, an advanced brush engine, non-destructivelayersand masks, group-based layer management,vector artworksupport, and switchable customisation profiles.
Name
[edit]The project's name "Krita" is primarily inspired by theSwedishwordskrita,meaning "crayon"(orchalk), andritawhich means "to draw".
History
[edit]Early development of the project can be tracked back to 1998 whenMatthias Ettrich,founder ofKDE,showcased aQtGUIhackforGIMPatLinux Kongress.The idea of building a Qt-based image editor was later passed to KImage, maintained by Michael Koch, as a part ofKOffice suite.In 1999, Matthias Elter proposed the idea of building the software usingCORBAaroundImageMagick.To avoid existing trademarks on the market, the project underwent numerous name changes: KImageShop, Krayon, until it was finally settled with "Krita" in 2002. The first public version of Krita was released with KOffice 1.4 in 2004.[7]In years between 2004 and 2009, Krita was developed as a generic image manipulation software likePhotoshopand GIMP.[8]
A change of direction happened to the project in 2009, with a new goal of becoming digital painting software likeCorel PainterandSAI.Also from that point, the project began to experiment with various ways of funding its development, includingGoogle Summer of Codeand funded jobs for students. As a result, the development gained speed and resulted in better performance and stability.[9]
TheKrita Foundationwas created in 2013 to provide support for Krita's development. It collaborated withIntelto create Krita Sketch as a marketing campaign and Krita Studio withKO GmbHas a commercially supported version for movie and VFX studios.Kickstartercampaigns have been used to crowdfund Krita's development since 2014.[citation needed]

Design and features
[edit]This sectionneeds additional citations forverification.(January 2020) |
The current version of Krita is developed with Qt 5 andKDE Frameworks 5.It is designed primarily forconcept artists,illustrators, matte and texture artists, and the VFX industry. It has the following key features:[15]
User experience design
[edit]Krita'sUXwas designed withgraphics tabletusers in mind. It uses a combination of pen buttons, keyboard modifiers and an icon-basedHUDto ensure frequently-used functions can be accessed by fewer clicks, without the need to search through text-based menus.
Most-used drawing commandscan be accessed via touch by combining keyboard modifiers with pen/mouse buttons and gestures:
Command | Input |
---|---|
Brush size +/- | Shift + Pen drag |
Pick colour | Ctrl + Pen tap |
Pan | Pen button + Pen move |
Zoom | Ctrl + Pen button + Pen move |
Rotate | Shift + Pen button + Pen move |
Pop-up Paletteis Krita's right click HUD. It enables instant access to the following functions:
Brush | Colour | View |
---|---|---|
10 loaded brush presets | Colour ring selector | Zoom |
Load other preset groups | FG/BG colour display | Rotate |
Brush size, opacity, flow, spacing, angle | Recent colour | Mirror |
Canvas-only | ||
Reset view |
Painting tools
[edit]Krita's core digital painting tools include:
Brushes | Drawing assistants | Selection tools | Transformation tools |
---|---|---|---|
Graphics tablet support | Adjustable interference intensity | Rectangle | Free position |
9 different brush engines | Infinite and parallel straight rulers | Ellipse | Rotate |
Modelled after real tools | Splines (curves) | Freehand (lasso) | Scale |
Highly adjustable | Ellipses | Polygon | Shear |
Remembers settings for each physical pen | Perspective | Outline | Perspective |
Pen stabilizer | Vanishing point | Fill | Warp |
Multibrush painting support | Fish-eye point | Color | Cage |
Opacity | Liquify |
Animation tools
[edit]Krita's animation tools are designed for frame-by-frame raster animation. They have the following features:
Interface | Import | Export |
---|---|---|
Similar interface toAdobe Animate | Batch import of frames | Render withFFmpeg |
Timeline controls | Output to individual frames | |
Real-time animation playback controls | Output to GIF, AVI, MP4, etc. | |
Onion-skindisplay |
Vector tools
[edit]Krita uses vector tools for non-destructive editing of the following objects:
- Path
- Selection
- Text (artistic, multiline, calligraphy)
- Vector art
- Fill and gradient
Layers and masks
[edit]Krita's layer and mask features include:
Layer management | Mask applies to | Non-destructive layers | Non-destructive masks |
---|---|---|---|
Multiple-level layer groups | Raster layers | Clone layers | Transparency masks |
Select multiple layers | Vector layers | Filter layers | Filter masks |
Drag-and-drop layers | Layer groups | Fill layers | Colourise masks |
Layer highlighting | Non-destructive layers | File layers | Transform masks |
Local selection masks |
Customisation
[edit]Krita's resource managerallows each brush or texture preset to be tagged by a user and quickly searched, filtered and loaded as a group. A collection of user-made presets can be packaged as "bundles"and loaded as a whole. Krita provides many such brush set and texture bundles on its official website.
Customisable tool panelsare known asDockersin Krita. Actions include:
- 2 customisable toolbars
- Toggle display of each docker
- Attach any docker to any sides of main window, or detach to float free
- Buttons to collapse/expand each docker panel
- Group dockers by tabs
Workspacesallow UI customizations for different workflows to be saved and loaded on demand.
Display
[edit]OpenGL accelerated canvasis used to speed up Krita's performance. It provides the following benefits:
- Better framerate and response time: pen actions can be reflected without delay
- Better-quality, fast and continuous zooming, panning, rotation, wrap-around and mirroring
- Requires a GPU with OpenGL 3.0 support for optimal experience. In the case of Intel HD Graphics, that meansIvy Bridgeand above.
Full colour managementis supported in Krita with the following capabilities:
- Assign and convert between colour spaces
- Realtime colour proofing, including colour-blind mode
- Colour model supported: RGBA, Grey, CMYKA, Law, YCbCr, XYZ
- Colour depth supported: 8-bit integer, 16-bit integer, 16-bit floating point, 32-bit floating point
Filters
