3 weeks ago, i have received a mail from a contributor named Holger Berger. He send me a patch against dcraw implementation included in libkdcraw, to parallelize demosaicing operations using OpenMP library. After some tests on my dual core computer i have immediately felt the power of parallelized code: it's faster.
We have tried to contact Dave Coffin to include this patch officially in dcraw... without success (no response). Why ? He don't like OpenMp certainly... So we have looked for another way to use this patch.
The digiKam development team is happy to release the 3rd beta release dedicated to KDE4. The digiKam tarball can be downloaded from SourceForge.
Take care, it's always a BETA code with many of new bugs not yet fixed... Do not use yet in production...
I am currently working with Andi Clemens to improve some important usability issues in Image Editor and Showfoto.
This is a great news for photographers: digiKam is now able to edit metadata from RAW files. Andreas Huggel from Exiv2 project has started to support writting mode with some TIFF/EP RAW files in this library. Currently Adobe DNG, Nikon NEF, and Pentax PEF file are supported.
See below a screenshot of digiKam for KDE4 editing XMP metadata from a NEF file:
JPEG, the current standard
Currently, all camera support JPEG format to store photograph. This format is very popular, robust. Image can be encoded/decoded very quickly and algorithm are very optimized to be embedded into device. Under Linux libjpeg is available and very stable, but is not maintained since a very long time.
I'm currently at Akademy 2008. The event is located in Belgium near Mechelen (south of Anvers).
This is really a big event about KDE community. It's very well organized (memorable social event in a Belgium brewery, with a lots of beer sponsored by Nokia who are connecting peoples really (:=)))...
There are severals entries in bugzilla about to be able to set a customized settings for each RAW image imported in editor. This is a advanced vision for photograph which want to adjust finely all settings during RAW workflow. I have started to implement a Raw Import tool for image editor. The first demo is available below:
The digiKam development team is happy to release the 2nd beta release dedicated to KDE4. The digiKam tarball can be downloaded from SourceForge.
Take care, it's always a BETA code with many of new bugs not yet fixed... To resume:
