Trait druid::Scalable

pub trait Scalable {
    pub fn to_px(&self, scale: Scale) -> Self;
    pub fn to_dp(&self, scale: Scale) -> Self;
}

The Scalable trait describes how coordinates should be translated from display points into pixels and vice versa using a Scale.

Required methods

pub fn to_px(&self, scale: Scale) -> Self

Converts the scalable item from display points into pixels, using the x axis scale factor for coordinates on the x axis and the y axis scale factor for coordinates on the y axis.

pub fn to_dp(&self, scale: Scale) -> Self

Converts the scalable item from pixels into display points, using the x axis scale factor for coordinates on the x axis and the y axis scale factor for coordinates on the y axis.
