Hello Pierre,

Hello Pierre,

I work with XnViewMP 1.8.0 on my windows system.

I saved a *.jpg image
- with some IPTC and also XMP tags
- as a *.jpg image encoded with JPEG-LI.
This worked properly, but a message was shown: storing this image all metadata will be lost.

I have seen that no metadata is lost.

Hello Pierre,

I copied all necessary *.dll from XnViewMP plugins directory into NConvert plugins.

Hello Pierre,

good idea, but sorry: also with OpenExr.dll in its plugin directory, NConvert does not convert a *.exr image.

I tried the same for *.flif images and it is working, when libflif.dll is inside plugins

Hello Pierre

Doing the test for NConvert 7.182 (a private version when posting this)
