The release of the raster graphics editor Krita 5.1.0, intended for artists and illustrators, has been presented. The editor supports multi-layer image processing, provides tools for working with various color models and has a large set of tools for digital painting, sketching and texture formation. Self-sufficient images in AppImage format for Linux, experimental APK packages for ChromeOS and Android, as well as binary assemblies for macOS and Windows have been prepared for installation. The project is written in C++ using the Qt library and is distributed under the GPLv3 license.
Main innovations:
- Improved work with layers. Added the ability to perform copy, cut, paste and clear operations for several selected layers at once. A button has been added to the layers control panel to open the context menu for users without a mouse. Provides tools for aligning layers in a group. Added support for drawing on selected areas using blending modes.
- Added support for WebP, JPEG-XL, OpenExr 2.3/3+ formats, as well as multilayer TIFF files with a layer structure specific to Photoshop. Added support for the ASE and ACB palettes used in Photoshop and other Adobe programs. When reading and saving images in PSD format, support for fill layers and color marks has been implemented.
- Improved image retrieval from the clipboard. When pasting, you can select options that allow you to use the features of placing images on the clipboard in different applications.
- A new CPU vector acceleration backend based on the XSIMD library has been implemented, which, compared to the previous VC library-based backend, has improved the performance of brushes that use color blending, and also provided the ability to use vectorization on the Android platform.
- Added profiles for YCbCr color spaces.
- An area for previewing the resulting color has been added to the Specific Color Selector dialog and the ability to switch between HSV and RGB modes has been implemented.
- Added option to scale content to fit window size.
- The capabilities of the fill tools have been expanded. Two new modes have been added: Continuous Fill, in which the areas to be filled are determined by moving the cursor, and the Enclose and Fill tool, in which the fill is applied to areas that fall within a moving rectangle or other shape. To improve smoothing of edges when filling, the FXAA algorithm is used.
- A setting has been added to the brush tools to determine the maximum speed of brush movement. Additional particle distribution modes have been added to the spray brush. Anti-aliasing support has been added to the Sketch Brush Engine. It is allowed to define separate settings for the eraser.
- It is possible to customize control gestures, such as pinch to zoom, touch to undo, and rotate with your fingers.
- The pop-up dialog with the palette offers additional settings.
- The menu for accessing recently opened files has been redesigned.
- Buttons have been added to the Digital Color Mixer interface to reset and save changes.
- A tool has been added to make it easier to draw circles in perspective.
- The Levels filter can be applied to individual channels.
- To reduce build time on developer systems, support for building with precompiled header files has been added.
- In builds for the Android platform, problems with using the OCIO color management system have been resolved.
- On the Windows platform, a transition has been made to a fresh code base for the ANGLE layer, which is responsible for translating OpenGL ES calls to Direct3D. Windows also provides the ability to use the llvm-mingw toolkit, which supports building for the RISC-V architecture.
