Implementations§

Source§

impl Density

Source

pub fn approx_dpi(self) -> Option<u32>

The DPI associated with the density class. See the Android screen density docs

There are some Density values that have no associated DPI; these values return None.

Source

pub fn approx_hidpi_factor(self) -> Option<f64>

The Hi-DPI factor associated with the density class. This is the factor by which an image/resource should be scaled to match its size across devices. The baseline is a 160dpi screen (i.e., Hi-DPI factor = DPI / 160). See the Android screen density docs

There are some Density values that have no associated DPI; these values return None.
