PixelDensity
class PixelDensity
Represents a pixel density, analogous to the pixel density of a physical display like a computer monitor or TV. It defines the mapping between pixels and physical distance in meters.
Use this class to perform consistent unit conversions between the pixel-based coordinate systems and physical spatial dimensions.
