[digiKam-users] Can digikam take advantage from modern graphic cards

[Gilles Caulier]

Hi,

Typically no. RAw decoding will take advantage of CPU cores, to run
demosaicing in parallel. GPU has nothing to do here. libraw used in
background do not use CPL language here, as i know. If something must be
improved here it's in libraw core, not digiKam.

But to be hosnest, using this kind of extension will decrease portability
and make the code less easy to maintain.

We are now based on Qt5 and GUI widgets take advantage automatically of GPU
computation to render image quickly on screen. There is no need to code in
Advanced language here, as all is done in Qt5 core.

Best
