v.0.21(L) Rotating thumbnails makes them disappear

[JohnFredC]

Ok, so no problem?

Well... if the file doesn't exist, XnView should not show anything at all about it.

So I consider it a

OK I have tried the rotate thing again with different results from yesterday.

This time the thumb cartouche remained but the thumb changed to the generic icon.

View->Rebuild thumbs has no apparent effect.

Navigating out of the folder and then back in restores un-rotated (i.e., original) thumb. File IS rotated, however.

Now, View->Rebuild thumbs causes the generic icon to appear.



Every day I try stuff with MP, it seems to behave differently.

Very strange. Are you in a folder? A category? Is it lossless rotation? A big file?

OK. After closing MP and restarting it, MP has returned to the behavior reported in the subject line.

The behavior differs between Filter By "All" and "Images". I have tested with both JPGs and PNGs, but only in folders, not categories. This is 100% reproducible behavior.

Scenario 1 (Images)

• 1. Customize the Browser toolbar to display an image rotation button.
  2. Show thumbs in the browser
  3. Set Filter By to "Images"
  4. Select an image
  5. Click a rotation button
  6. Thumbnail cartouche disappears

Scenario 2 (All)

• 1. Customize the Browser toolbar to display an image rotation button.
  2. Show thumbs in the browser
  3. Set Filter By to "All"
  4. Select an image
  5. Click a rotation button
  6. Thumbnail image switches to generic icon

Both Scenarios

• 7. Navigate out of folder
  8. Navigate back
  9. Observe that original thumbs (un-rotated) have returned
  10. Issue View->Rebuild thumbnails
  11. If Filter By is "Images", previously rotated files disappear (again).
  12. If Filter By is "All", generic icons re-appear
  13. Goto Step 7

Comments:

After using MP to rotate images, MP will no longer "rebuild" their thumbs... the thumb images are "stuck" at the version prior to rotation.

Changing the Filter By changes the behavior. If Filter By is "Images", rotated thumb cartouche disappears. If Filter By is "All", cartouche remains but thumb image switches to icon.

So I think there are (at least) two things happening:

• 1. A problem with Filter BY and recently rotated images.
  2. A problem with "Rebuild thumbs" for images rotated by MP.

and/or...

• 3. A problem with MP rotation itself? Though the images appear rotated correctly, perhaps something additional is wrong?

I can't reproduce. Which sort setting do you have? Which settings in Option/File list?

[JohnFredC]

Pierre... I'll see what I can figure out. So far the bug occurs 100% of the time.

Here are the file list options I am using:

Hi Pierre

Here is a little movie (2.4MB) demonstrating the rotation bug.

It's pretty much self explanatory.

Pardon the quality, it's my first and I am still learning about codecs etc...

Ok with your settings i can reproduce it!!!

Could you send me your email by PM, please?

Fixed v.0.25(L) I can find no settings where this happens again.
