Thumbnails are re-created if mode is changed

Post by Dreamer » Sun Oct 11, 2009 2:50 pm

I think it's not necessary. To reproduce:

- disable cache
- go to browser and wait until thumbs are created
- go to viewer and back to browser
= thumbnails are re-created again :bug: :?:

I'm not sure if this can be considered as a bug, but it's quite annoying, thumbnails should be retained until the path will be changed, alternatively option would help:

If thumbnail cache is disabled then:

( ) remove thumbnails on folder change
(o) remove thumbnails on exit

Perhaps this option might replace even the thumbnail cache option "Enable caching". Then 3 options would be needed - to always enable caching, remove thumbs on exit - and remove thumbs on folder change.

Current behavior (remove thumbs after mode change) is not needed at all IMHO.

Edit: Thumbnails are re-created also when comparing images - if that dialog is opened, thumbnails are re-created every time I delete a duplicate file - therefore it's freezing and quite unusable. I'm not sure if this is a bug :bug: , but it should be definitely changed IMO.

I can't confirm this problem, the thumbnails are not re-created...

Strange, I can't reproduce it either, now. :?

Re-display of a thumb and re-creation of a cached thumb (refresh) differ, but to the user the two actions can appear essentially the same.

In my experience, XnView frequently redisplays the thumbnails un-necessarily, even when the thumb cache is enabled.

An example of this occurs after executing jpg lossless rotation on a selection of thumbs in the browser.

To reproduce:

1. Switch to thumbnail mode in the browser
2. Select some files
3. Perform Tools -> JPEG Lossless transformation
4. XnView freezes (sometimes for a minute or so, depending on the size of the selection)
5. After a period of time, each rotated thumb (of the selection) is recreated in place
6. After the last thumb (in the selection) has been refreshed in place, the entire thumb panel redisplays!

#6 seems to me to be superfluous and unnecessary, not to mention irritating. The XnView GUI would "feel" much more "solid" if that extra refresh did not occur.

for #3-4 a progress bar will be great
Imi este indiferent ce cred ceilalti despre mine, caci oricum fiecare crede ce-i convine lui si nu ceea ce e real, doar ca mi-ar fi placut sa ma vada asa cum sint de fapt, nu asa cum poate le-ar placea lor sa creada. Ei au ales deja...
