Name

The project's name "Krita" is primarily inspired by the Swedish words krita, meaning "crayon" (or chalk), and rita which means "to draw". It follows the "K" prefix like everything else in the KDE suite.^{[citation needed]}

History

 

The Krita team in 2014

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.^[7] In years between 2004 and 2009, Krita was developed as a generic image manipulation software like Photoshop and GIMP.^{[citation needed]}

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.^[8]

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.^{[citation needed]}

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:^[17]

User experience design

 

Krita's right-click HUD, the Popup-palette

 

Pencil tool work

The most prominent feature of Krita is arguably its UX design 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
		Canvas-only
		Reset view

 

Controls of one of Krita's many brush engines

 

Krita's stock brushes

Painting tools

Krita's core digital painting tools include:

Brush	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

 

Krita's animation workspace (4.0 version)

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

 

Krita's vector tools

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

 

Krita's layer and mask controls

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
			Local selection masks

Customisation

 

Krita's resource manager

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

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

 

Text quality on Krita's OpenGL canvas with non-integer zooming, rotation and mirror

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.

 

Krita's colour space loader

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, CMYKA, Law, YCbCr, XYZ
• Colour depth supported: 8-bit integer, 16-bit integer, 16-bit floating point, 32-bit floating point

Filters

 

Krita's G'MIC filter controls

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, color 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.

Import only	ODG draw, Krita Flipbook, Adobe DNG, Camera RAW, PDF, SVG, XML, XCF
Export only	[none]

Mascot

 

Krita's Steam box art in 2014, featuring Kiki

Krita's mascot is Kiki the Cyber Squirrel, a robotic, anthropomorphic squirrel character created by Tyson Tan. The community collectively decided the mascot to be a squirrel. The first version of Kiki was posted to the KDE forum in 2012^[18] and was used in Krita version 2.6's introduction booklet.^[19] Kiki has been used as Krita's startup splash screen since Krita version 2.8.^[20][21] So far, each new version of Krita has come with a new version of Kiki. Kiki has been used for Krita's merchandise shop items^[22] and Krita's Steam project artworks.^[23][24]

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.
