When changing the splash logo
balena-logo.png file inside the boot partition, it correctly gets displayed in place of the green balena logo on boot
However, it’s always displayed on a white background. This means that in order to display a white logo on black background, I need to make my image non-transparent, with a black background.
This works fine if I know the aspect ratio of the screen in advance. However, when the aspect ratio is different, white borders appear at the top and bottom or sides depending on the screen.
Is there a way to configure the splash screen background color, or have the image resize (while keeping the aspect ratio) to cover the whole screen? This would crop some parts of the image when the aspect ratio is different, but it’s totally acceptable in my case.
EDIT: found this theme script that basically defines the splash screen. Can we override this script with a custom one from the boot partition, just like we do with the png?
