Krita

Krita ( ) is a free and open-source raster graphics editor designed primarily for digital art and 2D animation.

Originally created for Linux, the software also runs on Windows, macOS, Haiku, Android, and ChromeOS, and features an OpenGL-accelerated canvas, colour management support, an advanced brush engine, non-destructive layers and masks, group-based layer management, vector artwork support, and switchable customisation profiles.

The software is also available as paid software, distributed on Microsoft Store, Steam, Epic Games Store, and Mac App Store. Payments support the development of the software. The paid version has automatic updates.

Name The project's name "Krita" is primarily inspired by the Swedish words , meaning "crayon" (or chalk), and which means "to draw" as well as Sanskrit कृत (kṛta) which means "made"/"done".

History

Early development of the project can be tracked back to 1998 when Matthias Ettrich, founder of KDE, showcased a Qt GUI hack for GIMP at Linux Kongress. The idea of building a Qt-based image editor was later passed to KImage, maintained by Michael Koch, as a part of KOffice suite. In 1999, Matthias Elter proposed the idea of building the software using CORBA around ImageMagick. 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. In years between 2004 and 2009, Krita was developed as a generic image manipulation software like Photoshop and GIMP.

A change of direction happened to the project in 2009, with a new goal of becoming digital painting software like Corel Painter and SAI. Also from that point, the project began to experiment with various ways of funding its development, including Google Summer of Code and funded jobs for students. As a result, the development gained speed and resulted in better performance and stability.

The Krita Foundation was created in 2013 to provide support for Krita's development. It collaborated with Intel to create Krita Sketch as a marketing campaign and Krita Studio with KO GmbH as a commercially supported version for movie and VFX studios. Kickstarter campaigns have been used to crowdfund Krita's development since 2014.

Design and features

The current version of Krita is developed with Qt 5 and KDE Frameworks 5. It is designed primarily for concept artists, illustrators, matte and texture artists, and the VFX industry. It has the following key features:

User experience design

Krita's UX was designed with graphics tablet users in mind. It uses a combination of pen buttons, keyboard modifiers and an icon-based HUD to ensure frequently-used functions can be accessed by fewer clicks, without the need to search through text-based menus.

Most-used drawing commands can 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 Palette is 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

Painting tools 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

Animation tools Krita's animation tools are designed for frame-by-frame raster animation. They have the following features: Interface Import Export Similar interface to Adobe Animate Batch import of frames Render with FFmpeg Timeline controls Output to individual frames Real-time animation playback controls Output to GIF, AVI, MP4, etc. Onion-skin display

Vector tools 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 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

Customisation

Krita's resource manager allows 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 panels are known as Dockers in 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 Customisable Brushes and Brush Engine allows advanced users to create custom scripts on brush behavior, patternlike textures, geometrically shaped brushes and simulated blending through programming, most notably via Python plugin support however, other programming languages are also supported like Lua.

Workspaces allow UI customizations for different workflows to be saved and loaded on demand.

Display OpenGL accelerated canvas is 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 means Ivy Bridge and above.

Full colour management is 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 Scale, CMYKA, Law, YCbCr, XYZ Colour depth supported: 8-bit integer, 16-bit integer, 16-bit floating point, 32-bit floating point

Filters

Krita has a collection of built-in filters and supports G'MIC filters. It has real-time filter preview support.

Filters included in a default installation: levels, colour adjustment curves, brightness/contrast curve, desaturate, invert, auto contrast, HSV adjustment, pixelise, raindrops, oil paint, gaussian blur, motion blur, blur, lens blur, colour to alpha, colour transfer, minimise channel, maximise channel, top/left/bottom/right edge detection, sobel, sharpen, mean removal, unsharp mask, gaussian noise removal, wavelet noise reducer, emboss horizontal only/in all directions/(laplacian)/vertical only/with variable depth/horizontal and vertical, small tiles, round corners, phong bumpmap.

File formats supported Krita's native document format is Krita Document (.kra). It can also save to many other file formats including PSD. File formats Save to Krita Document, OpenRaster document, PSD image, PPM, PGM, PBM, PNG, GIF, JPEG, JPEG XL, Windows BMP, XBM, XPM, TIFF, EXR, Gimp image, WebP, SCML, ICO, TGA, CSV, QML Import only ODG draw, Krita Flipbook, Adobe DNG, Camera RAW, JPEG 2000, PDF, SVG, XML, XCF

Sprint events Krita sprints are events during which Krita developers and artists get together for a few days, exchange ideas and do programming face-to-face, in order to speedup development and improve relationships between members.
