XnView Software

If you save metadata in the single image view mode, they are not actually saved.
If you go to the browser mode, you can see that the metadata is not preserved thereafter.

you means IPTC?

Pierre, is there a quality loss when saving image this way ?

you recompress the data, so for JPEG yes.
Or perhaps i can a 'Write' button?

Yes, a "Write metadata" button.

See issue for current status and some details.

This problem is supposed to be fixed in XnView MP 0.94. Please check and confirm the bug fix here.

Solved
"Write" button is ok


But what is the use of "Apply" button ?

A good question. I have edited this reply, since my original comment was wrong.
"Apply" saved your changes in the program's internal copy of the image metadata. You can even view one image next or previous and the changes are still there, but not yet saved to disc until you select "save". There is no warning if you do not save.

I think it should be changed to either

• remove the "apply" button, or
• set the "edited" state so the user can be warned

I thought it might apply changes on the options tab, but these seem to be applied immediately, even if you press "cancel"
