BUG: Picture metadata changes aren't saved

I have a picture that I saved from Paint.NET to my desktop. When I select the file in DOpus and press F9 I can see the metadata for the picture. However, I can't save any changes to the metadata. Changes are also not saved when I make changes via the Set Metadata window.

I'm using DOpus Pro 10.5.4.0 (5080) x64 on Windows 7.

Steps to reproduce:

  1. Select picture. In my case it's a PNG file.
  2. Press F9 to open metadata pane OR press CTRL-M to open the Set Metadata window. Both have the same problem.
  3. Edit the "Creation Software" field. A red triangle will appear to the left of the field name.
  4. Press Apply (in the pane) or OK (in the window).

Result:
The metadata changes are not saved and the "Creation Software" data reverts to the original value.

Expected result:
The metadata should be saved.

Could you send a small example PNG that this happens with? I'm unable to reproduce it using ones I've created myself.

Hi Leo,

I was able to recreate this with a PNG image created in Paint.net by following the steps that Matt2 outlined above.

I am using:
Directory Opus Pro 11.0.3.5116 x64
OS 6.1 (B:7601 P:2 T:1) SP 1.0 "Service Pack 1"

An example PNG would be most useful.

I have found that the metadat is saved with some .png files but not others. I have attached 2 such files appropriately named.



HTH.

Is it only the Creation Software field that can't be edited? I can confirm that, but the other fields I've tried seem OK.

Is the same true for the other people in this thread, or are these two different issues? (The image above was created in Adobe Fireworks rather than Paint.Net, so I don't know if it's the same underlying problem, although it seems likely it is if it's only the Creation Software field that's the problem.)

In my case (using the first image above), it appears that it is only the Creation Software field that cannot be altered. I changed every metadata field and they all 'stuck' OK except "Creation Software".

Here's the image I created and was using to test when I wrote the bug report: f.cloud.github.com/assets/24875 ... 746e74.png

I downloaded it and verified that I can still reproduce the problem (I had deleted it after uploading it to github). As others mentioned, it appears that only the "creation software" field will not keep applied changes. I apologize for not testing all of the other fields before filing the report. I'll be more thorough next time.

I saved the two images via a right-click and "save image as" in Firefox. I was able to successfully edit and apply the creation software field in both of them, so I can't reproduce the behavior that Rebel154 is seeing. Is there a different way to save the files from the forums? Maybe it's because I'm using version 10 and not the 11 beta.

Is anyone aware of a program to check if a PNG is formatted properly and following the specification? I'm wondering if this could be a bug in how Paint.NET creates PNG files rather than a problem with DOpus.

Hi Leo,

The two test pictures supplied by Rebel154 worked exactly as described for me. Doesn't Save Metadata.png failed to save any changes made to the Creation Softaware Field. Whereas Does Save Metadata.png did save changes.
All the other fields do appear to be saving any changes made to them. The following is the image I first used to confirm Matt2's original report.


I hope this helps.
Stu.

Thanks all for your input. This will be fixed in the next update.
