Description Alex6 2023-12-23 15:37:36 UTC

The "full screen" view displays images at maximum size, both horizontally and vertically.

A display zone using a central area in the screen, of a size chosen by the user (the rest of the screen being filled with the display background color) would make it possible to:

- 1) avoid the not always pretty confrontation of the displayed image with the "hard" screen border (keeping a small margin between image and screen edge)

- 2) limit scale breaks between "portrait" and "landscape" images, particularly with the trendy "super extra ultra wide" displays


Thanks to KPA on behalf of my 30,000 photos & images!

Hi Alex,

Since you explicitly mention the image scale / zoom level: just adding a padding to the viewer would do nothing to limit scale breaks. I suppose you would like an option to specify a (persistent) zoom level across images?

Cheers,
  Johannes

I agree. The benefit of this padding would be to have a margin  to isolate the displayed image from the screen border.

No.

Let's take an example:
A "panoramic" image (16/9), whatever the actual size, displayed on a 1920*1080 screen with current kpa viewer:
- 16/9 landscape: image displayed 1920*1080 px
- 9/16 portrait: image displayed 607*1080 px

With a display area 1200*1060 px on the same screen
- 16/9 landscape: image displayed 1200*675 px
- 9/16 portrait: image displayed  597*1060 px
which reduces the display gap between "portrait" and "landscape" images

Happy Christmas ( even posthumously !)
