1.7.2 - browser - thumbnails - issue with embedded thumbnails

Post by user0 »

XnViewMP 1.7.2
Windows11 (23H2), display resolution 3840x2160, dpi scale 150%

Browser - filelist - thumbnails
video, may be related to win dpi scale, like this issue

To reproduce:
0. prerequisites
- clean unziped app version
- unzip test files (two files [2.jpg embedded as thumbnail into 1.jpg] and subfolder with the same files)
test_img.zip
(38.64 KiB) Downloaded 40 times


Issue A
1. disable Catalog, restart app
2. open test folder in Browser
3. slowly change thumbnails size in 120-300px range (back and forth)
- via slider OR
- switch slider to thumbs-per-column mode and resize app window

A1 - folder thumbnail
  • size <155
    folder thumbnail will be generated from file's embedded thumbnails
  • size >155
    folder thumbnail will be generated from file
expected behaviour
generate thumbnail as per app default settings:
☑ Use embedded thumbnails
☐ Create from original image if embedded thumbnail is smaller than thumbnail size

A2 - file thumbnail
2.jpg - thumbnail size uses "Best fit" - OK
1.jpg - embedded thumbnail stretches up to ~298px, then becomes original size (115x120px)
expected behaviour
rendered thumbnail should always use "Best fit" sizing (fit to thumb cell, large only)


Issue B
1. set Cached thumbnails size to 20x20px
- clean DB
- restart app
2. open test folder in Browser

B1 - overlay icon
1.jpg has "Embedded thumbnail" overlay icon
3. enter subfolder
4. exit subfolder
1.jpg has no "Embedded thumbnail" overlay icon

B2 - file thumbnail
same issue as A2
