0.84: Image's metadata lost when saving

[m.Th.]

How to lose your work in few easy steps:

1. Get a JPG (or any other format which supports metadata embedding)
2. In Thumbs Pane press Ctrl+I to bring the IPTC/XMP dialog
3. Enter some text in the Caption field
4. Save
5. Double-click to open the image in a new tab
6. Do any edit (for example Crop - it doesn't matter)
7. Save

8. Close tab & Return to Thumbs pane and press Ctrl+I (WHY should I return to the Thumbs pane in order to see the metadata of the open file???)

Expected: I should see in the Caption field the text entered at step 3.
Actual: Blank! - all data is wiped

I can't reproduce, the caption is always here. Which setting do you have for IPTC/XMP dialog?

8. Close tab & Return to Thumbs pane and press Ctrl+I (WHY should I return to the Thumbs pane in order to see the metadata of the open file???)

What do you mean?

Did you receive my movie by PM?

I can't reproduce the problem either: After croppinig and saving the IPTC data (Caption, caption writer, ...) is still there. (correct).

@Pierre: What is the status of this problem?

[m.Th.]

The current status: DANGEROUS (I think)

The „bug” is controlled by JPEG Write Settings. To find them, double click on an image and go to File | Format Settings | Write | JPEG

Here you have 3 checkboxes at the bottom: Keep EXIF, IPTC, XMP. Check all of them.

I don't remember now how it is by default, but if these are Disabled then the problem persists. It is rather a wrong choice for the default settings.

Thank you for these details that allowed to reproduce the problem, m.Th..

By default, all three checkboxes "Keep EXIF", "Keep IPTC", and "Keep XMP" are checked.

Possible measurements to avoid such problems:
- "Format settings" should be integrated into the save dialog using a "Settings" or "Options" button. This will improve the workflow and the user might remember that he/she might need to modify these settings when saving. (Someone has requested this before but I couldn't find it.)
- "Format settings" should be part of the settings. (Currently one can only change the format settings in Viewer).

But Pierre has indicated that that (a normal feature in software in general) currently can't be implemented in 'MP due to Qt limitations...

It is one of two issues (the other related to access to some basic print settings) that can't currently be implemented as far as I'm aware for that reason, a possible subject for an update from Pierre?

At least two buttons [Write Settings] [Read Settings] in Tools | Settings | Formats which will open the Viewers' dialogs discussed above.

Adding new tabs "Format" to Settings dialog should be feasable and no problem. If I understood Pierre right, placing buttons on standard dialogs is a problem in Qt.

Yes, it was suggested before that save settings would be better located in Tools > Options than as at present in the File menu, but where access to save settings is really needed is in the Save dialog, as in XnView Classic and other programs...

There is already such a section. Just add some buttons there to show up these windows...

No problem. A window can be accessible from many locations. I don't see any problem with this...

The current status: DANGEROUS (I think)

I agree.

This situation actually surprises me - I always assumed those settings were for save-as and otherwise saving new copies of an image.
I would expect that simply saving an existing jpeg with modified content would use its current values such as compression quality and metadata.

What happens if you modify the metadata? does updating the file with new metadata also cause the metadata to be deleted if those options are set?

I can understand how the problem arises. I recently did a batch process of writing to new jpegs and wanted to remove some of the metadata, the ICC, wrote lower quality and resize. This requires modifying the format write options and if I did not remember to reset all the options to sensible values then I could have made a mess of a lot of image files.

It is also not good that I cannot access "format settings" from anywhere on the browser page, except the batch process dialog. I can do a right-click->convert into jpeg, but I cannot see nor change what the settings are.

So you would like that i add a new section 'Formats' in Settings (before 'Integration'), right?

I'd prefer if the category for format settings would be more at the top. In XnView Classic these settings are in General » Read/Write.
