[Interest] Poor downsizing of High DPI pixmaps on Low DPI displays

[Etienne Sandré-Chardonnal]

Dear all,

I have set a High DPI image as a splash screen in my application, by
providing an image which is twice larger, and set the pixmap scaling to 2.

On a double DPI monitor, the result is perfect. But on a standard monitor,
the downsizing is very poor, it looks like the pixmap was scaled using a
simple nearest neighbor filter.

Is there a way to set a flag for smooth scaling for pixmap with a scale
ratio above 1?

Thanks
