Bug ID: 474862
Summary: Improving Responsivness of KDE by Optimizing KDE PNG
Wallpapers [12.7 MiB is Way Too Big]
Classification: Plasma
Product: Plasma Workspace Wallpapers
Version: 5.27.8
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: kdelo...@mozej.com
Target Milestone: ---
All .png KDE wallpapers are way too big in size and hence slow to load. We can
improve loading (login screen, lock screen, desktop wallpapere) by properly
optimizing all PNG wallpapers. Since kimageformat supports modern compression
methods, I read all the documentations, man pages and conducted close to 1000
tests using various methods and advanced options for modern photo/picture/raw
data compression. In order to decrease the size of enormous PNGs of KDE
wallpapers, I compressed all png wallpapers using all adanced options possible
to achieve maximum quality while compressing these pictures. Please conduct
blind tests for two versions (see attatchments) and decide which one would you
like to include as default KDE wallpapers in the next version of KDE.
See how slow all pngs are to browse with Gwenview (put all PNGs in one folder)
and how fast are the compressed photos are to browse. BTW you will not see any
quality loss doing blind test.
1. Problem:
13Megabytes for a wallpaper/lock/login screen/sddm is way too big.
2. Solution:
Very high quality modern compression methods already in attatchments
3. Please update links in the appropriate folders (/usr/share/wallpapers/) to
the new compressed ones insead of the big PNGs
