program release , which provides tools for editing photos and converting images in RAW format. The program supports a large number of RAW file formats, including cameras with Foveon- and X-Trans sensors, and can also work with the Adobe DNG standard and with JPEG, PNG and TIFF formats (up to 32 bits per channel). The project code is written in C++ using GTK+ and licensed under GPLv3.
RawTherapee provides a set of tools for color correction, white balance, brightness and contrast, as well as automatic image enhancement and noise removal. Several algorithms have been implemented for image quality normalization, lighting correction, noise suppression, detail enhancement, extra shadow control, edge and perspective blockage correction, automatic removal of dead pixels and exposure change, sharpening, removal of scratches and dust marks.
In the new release:
- Added support for pseudo-HiDPI mode, which allows scaling the interface for different screen sizes. The scale automatically changes depending on DPI, font size and screen settings. By default, this mode is disabled (enabled in Preferences > General > Appearance);
- A new "Favorites" tab has been introduced, where you can move frequently used tools that you would like to always keep at hand;
- Added "Unclipped" processing profile, which makes it easier to save the image while leaving data in the entire tonal range;
- In the settings (Preferences > Performance), it became possible to override the number of image tiles processed in a separate thread (tiles-per-thread, the default value is 2);
- Made a large portion of performance optimizations;
- There are issues with scrolling dialogs when using GTK+ 3.24.2 to 3.24.6 releases (GTK+ 3.24.7+ is recommended). It also now requires librsvg 2.40+ to work.
Additionally, it can be noted photo collection management software . New release introduces new interface for plugin development , which replaced the previously supported KIPI interface and provides more opportunities to expand the functionality of various parts of digiKam, without being tied to the digiKam Core API. The new interface is not limited to Main Album View and can be used to expand the functionality of Showfoto, Image Editor and Light Table modes, as well as better integration with all major digiKam tools. In addition to functions such as import/export and metadata editing, the DPlugins API can be used to extend the functions of palette editing, transformation, decoration, applying effects, and creating handlers for batch work.
Currently, 35 general plugins and 43 image editing plugins, 38 plugins for Batch Queue Manager have already been prepared based on the DPlugins API. General plugins and plugins for the image editor can be enabled and disabled on the fly while working with the application (dynamic plugin loading is not yet available for Batch Queue Manager). In the future, it is planned to adapt DPlugins to other parts of digiKam, such as image loading handlers, camera operations, database components, face recognition code, etc.
Other changes:
- Added a new plugin for copying items to local storage, replacing the old tool based on the framework and used to transfer images to external storage. Unlike the old tool, the new plugin uses only the features of Qt without the involvement of KDE-specific frameworks. Currently, only transfer to local media is supported, but support for accessing external storage via FTP and SSH, as well as integration with Batch Queue Manager is expected in the near future;
- Added plugin for setting image as desktop wallpaper. Currently only wallpaper management is supported on the KDE Plasma desktop, but support for other Linux desktop environments, as well as macOS and Windows is planned;
- Buttons have been added to the built-in media player to change the volume and loop the current playlist;
- Added the ability to change the font properties for comments shown in slideshow mode, as well as support for hiding comments by pressing F4;
- Added support for sorting by file modification time in Album Icon-View;
- Updated AppImage assemblies that are adapted for more Linux distributions and translated to Qt 5.11.3.
