ScaledPixels

Struct ScaledPixels 

Source
pub struct ScaledPixels(/* private fields */);
Expand description

Represents scaled pixels that take into account the device’s scale factor.

ScaledPixels are used to ensure that UI elements appear at the correct size on devices with different pixel densities. When a device has a higher scale factor (such as Retina displays), a single logical pixel may correspond to multiple physical pixels. By using ScaledPixels, dimensions and positions can be specified in a way that scales appropriately across different display resolutions.
