Viewer - navigation - add fast mode

Post by user0 »

XnViewMP 1.12.3
Windows11 (26H2), display resolution 3840x2160, dpi scale 150%


Viewer - navigation
navigation, mode switching or tab closing are unavailable until file has fully loaded, which is inconvenient
to reproduce
0. have ~5 large files in folder
1. open one in Viewer and quickly switch between them via keys/mouse scroll
2. try to navigate further (next/prev, last/first, random), switch mode or close tab
it will not be possible until current image is fully loaded

Suggestion
  • add 'fast' navigation mode (eg like in MS Photos, ACDSee, ImageGlass)
    navigation commands interrupt loading of current image and immediately initiate loading of the next image
  • improve 'slow' navigation mode
    - do not queue navigation commands in 'slow' navigation mode (eg like ImageGlass)
    if user presses navigation keys or scrolls multiple times while an image is loading, additional navigation commands should be ignored.
    Only navigation commands issued after current image has finished loading should be executed.
  • general improvement for both modes
    - closing tab command should abort loading
    - switching mode should switch mode immediately and continue to load in background
    - add setting to switch modes (like in ImageGlass)



Example
  • ImageGlass
