I'm writing a tool using minifb that shows things tothe user. I'd like to scale these things based on the display scale. Are there any crates that can get me the display scaling factor in a cross-platform manner? Ideally, there would be a function that I can call to just get it as a float, to avoid any complicated systems.
winit provides access to the scale factor using MonitorHandle::scale_factor, Window::scale_factor, and ScaleFactorChanged event. Note that the scale factor may change dynamically when the user moves the window to another monitor or changes DPI settings.
minifb is not based on
winit, so it's hard to integrate them. You could just get the first monitor's scale factor, but it won't cover the multiple monitors case. You can consider switching from
minifb to its
winit-based alternative, pixels.
I guess that that works as a hacky way of doing it, but the multi-monitor issue does matter. As for using winit+pixels, that's problematic because AFAIK pixels requires a Vulkan-comaptible GPU to do anything, which is problematic for what I'm doing, hence why I'm using minifb.
