[Interest] How to render small Images decently on non retina displays with QtQuick?

[ekke]

I'm using QtQuickControls2 and Qt::AA_EnableHighDpiScaling
and so all my images are deployed with my app in different solutions

per ex a 24x24px Icon
test.png (24x24) -- for 160 dpi --
test at 2x.png (48x48)
test at 3x.png (72x72)
test at 4x.png (96x96)

and so for all devices with all kind of dpi by magic the Icons and
Images are looking same

if you don't use the HighDpiScaling you can try to check the density and
then scale your Image or deploy your Images/Icons similar to @2x, ...
and select the right one for dpi of actual device running on
