Bug ID: 472924
Summary: Pinch to Zoom on a touch screen zooms to the center of
the screen and not to the intended part of the page
Classification: Applications
Product: okular
Version: 23.07.80
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: okular-de...@kde.org

SUMMARY
When I pinch to zoom on a touch screen, Okular zooms to the center of the page.
I expect it to zoom to the portion of the page where I initially placed my
finger.
STEPS TO REPRODUCE
1. Open a pdf in Okular running on a touch screen computer
2. Try to zoom in with two fingers
OBSERVED RESULT
Okular zooms into the center of the page (even if I initially placed my fingers
at the edge of the page)
EXPECTED RESULT
Okular should zoom in to the position of the page where fingers were placed
initially.
This is the behavior when I zoom into PDF readers in Android phones/tablets
(and also in Firefox PDF viewer in Linux).
SOFTWARE/OS VERSIONS
