[digiKam-users] refreshing folders doesn't work (dk 6.0.0)

Uwe Haider
Hi,

I do my raws with darktable and export the finished pictures as png back
to the digikam folder with the raw. This worked all the time. Now I can
refresh this folders in dk 6.0.0 but the new pngs exported from
darktable seem not to be there. No one is shown...

QtPhoto shows this files.

Is there a size limit for pngs? The missing files are > 100 MB (no
compression).

Hi,

PNG file has no size limitation.

If you can share a sample through the cloud, we can investigate.

Showing console messages can help also.

Best

Re: refreshing folders doesn't work (dk 6.0.0)

The PNG file is broken and can not be loaded by any image loader.

This problem comes from a buggy version of Exiv2-0.26 / 0.27. The problem will
not be resolved until Exiv2 > 0.27. This also affects Darktable when you write
metadata in PNG files. At the moment I am considering to handle digiKam PNG
files like RAW files. At the moment I can only advise against writing metadata
in PNG files. The ICC profile can be destroyed if the profile name is
different from the standard.

Here libpng giving up. The problem could have been caused by the previous
error.
