Software-update: digiKam 6.2

digiKam logo (75 pix) Versie 6.2 van digiKam is uitgekomen. Deze fotobeheer- en beeldbewerkingsapplicatie heeft downloads voor Linux, BSD, macOS en Windows. Het bevat ondersteuning voor uiteenlopende bestandsformaten en kan daarnaast via plug-ins van meer mogelijkheden worden voorzien, zoals het exporteren van een album naar Facebook of Flickr. Meer over de mogelijkheden van dit programma is op deze pagina te vinden. De release notes voor deze uitgave zien er als volgt uit:

New Cameras Supported by Raw Files Engine

digiKam tries to fully support all digital camera formats. However, Raw file support is a big challenge. This complexity, and the associated difficulty and commitment required to continue full support over time, has led to the development of applications specifically created only to support Raw files.

Raw files are not like JPEG. Nothing is standardized, and camera makers are free to change everything inside these digital containers without documentation. Raw files permit manufacturers to reinvent existing methods, implement hidden features, cache metadata, and require a powerful computer to process data. When you buy an expensive camera, you might expect that the images provided are seriously pre-processed by the camera firmware and ready to use immediately.

This is true for JPEG, not Raw files. Even if JPEG is not perfect, it’s well standardized and well documented. For Raw, the formats can change with each new camera release as it provides raw, in-depth on-camera sensor data not processed by camera firmware. Supporting these changes requires intensive reverse-engineering that the digiKam team cannot directly support. Consequently, we use the powerful LibRaw library to post-process the Raw files on the computer. This library includes complex algorithms to support all different Raw file formats.

In digiKam 6.2.0, we use the LibRaw 0.19.3 maintenance version which introduces a few new Raw formats to support the most recent camera models available on the photo market. See the list below for details:

  • Canon Powershot A560
  • FujiFilm X-T30
  • Nikon Coolpix A1000, Z6, Z7
  • Olympus E-M1X
  • Sony ILCE-6400
  • Several dng files from phones and drones.

This LibRaw version is able to process in totality more than 1000 Raw formats. You can find the complete list in digiKam and Showfoto through the Help/Supported Raw Camera dialog or at this url.

Thanks to the LibRaw team for sharing and maintaining this experience.

Low Level File Metadata Library Exiv2 0.27.2 Support

With this new release we are following the Exiv2 project which has released their new stable version 0.27.2. This library is a main component of digiKam and used for file metadata interactions like populating database contents, updating item textual information, or handling XMP side-cars for read only files.

digiKam 6.2.0 now supports the new API of this library. All 6.2.0 binary bundles that we package for Windows, MacOS and Linux have been compiled with this Exiv2 version.

Embedded Video Player QtAV 1.13.0 Support

In release 5.5.0 we began using the QtAV framework to play video media in digiKam. We chose QtAV because this framework directly uses ffmpeg codecs which de facto supports all formats very well. In contrast, the QtMultimedia framework requires extra platform codecs that end users need to explicitly install to obtain functional video support. digiKam users should not need to install extra programs for video; it should work automatically upon installation. digiKam must be as simple to deal with video as it is for photo.

digiKam has the capability to play video files directly, without requiring an extra video player and dedicated codecs (thanks to FFmpeg and QtAV frameworks).

2 years ago, QtAV 1.12.0 was released with CMake support, but no updates were published since. We were very happy to see a new release available just in time to follow the digiKam 6.2.0 release plan, and so digiKam has been updated to support the new API from the QtAV 1.13.0 library. All 6.2.0 binary bundles that we package for Windows, MacOS and Linux have been compiled with this QtAV version.

Iconview : HiDPI Support for 4K Screens

With this release, Album management gets a new feature: support for icon-view items rendering on HiDPI 4K screens. Before this digiKam release, if you have a 27 inch 4K display (typically with a resolution of 3840x2160 pixels), the icon view contents became small and pixelated. Now, digiKam scales up images to display them correctly on HiDPI-enabled screens. To use this feature, go to the Setup/View/Icons configuration dialog page.

Portable Archive for Windows

With this release, we start to support the Portable project to publish a 32 and 64 bits archive of the official Windows installers internal contents. This permit to end-users to just uncompress the binary tarball in home directory, and run digiKam or Showfoto as well without to use the standard Windows installer, as this one can require administrator rights. Of course, this method do not register the application links to Start menu and is only available to just one end user.

Wijzig sortering
Ik had inderdaad even gemist dat 6.2 alweer van begin augustus is. Versie 6.3 is nog in ontwikkeling en alleen als pre-release beschikbaar.
Ah ok, ik werd even op het verkeerde been gezet door deze header in bovengenoemd bestand:
digiKam 6.3.0 - Release date: 2019-09-08
Dat lijkt op een release, maar blijkbaar nog niet officieel aangekondigd dus ;)
