Is support for the OpenEXR format on the horizion for digikam at all?  I've started using that format and find it really helpful; would love to work with those files in digikam. 

OpenEXR (https://openexr.com) is an open source project under the auspices of the Academy Software Foundation, a part of the Academy of Motion Picture Arts and Sciences (the group that awards The Oscars for movies). 

It seems to have a pretty robust library for handling the format at:

Note I am currently using digikam 8.4.0

Thanks!

Erik

EXR is already supported by digiKam since a while through the KDE Qt image loader plugins :

Just add "exr" as extra type mime in digiKam setup dialog.

Thank you for the information on the mime type tweak and putting it into the default for the next version of digikam.

I was able to get the mime type tweak mentioned working.  I will note that the rescan feedback digikam gave me after I made the change was not what I would have expected given how the scanning for new items usually works; the usual progress bar wasn't triggered.  I was able to see that work was being done by the spinning circle of a prompt in a digikam window and by launching it in a terminal and watching the output to stdout/stderr.

Regards,

Erik
