1.9.1 - browser - thumbnails - fix scaling
Posted: Thu May 29, 2025 11:38 am
XnViewMP 1.9.1
Windows11 (24H2), display resolution 3840x2160, dpi scale 150%
Browser - thumbnails
follow-up on this issue, also related to slider issue
To reproduce:
0. prerequisites
issue A
100-149px image will be stretched to 150px
expected:
thumbnails should be the same size as at 100% win dpi scale
however, it may be useful to add 'Fit small image to thumbnail size' option in Settings > Thumbnails
(but, obviously, it should apply to all small thumbnails, not selectively)
issue B
Thumbnail size will be 170px
custom thumbnail size (100px) * dpi scale (1.5) + margins (10px)
which
- conflicts with thumbnail size, which is explicitly set to 100x100px AND
- affects slider
expected:
do not scale thumbnail cell when HiDPI scaling option is off
on the other hand, this 'automatic' scaling may be useful for someone (who often switch dpi scale?), so
maybe

maybe
- split scaling setting to
- content (image in Viewer/Preview and thumbnail)
- UI (thumbnail size, maybe something else [font, icons])
