[Bartosz Kosiorek <gang65@xxxxxxxxxxxxxx>]

The proposal to merge lp:~gang65/music-app/music-app-reduce-png-size into lp:music-app has been updated.

Description changed to:

Reduce size of png images (with tinypng.com) to decrease click size and improve performance

The size of graphics directory was decreased from 200kB to 36kB.

I checked how reduce PNG size impacts performace with QML Profiler.
For ClockCircle.qml with optimized png files and without.

Not optimized PNG files:
QtQuick/Loader Background: 2.554ms
QtQuick/Image Inner Clock: 4.921ms

Optimized PNG files:
QtQuick/Loader Background: 1,246ms
QtQuick/Image Inner Clock: 2.347ms

I repeated tests several times, and the results are similar.

Benefits:
1. Smaller Click package
2. Improve performance
