Required Methods

fn into_px(self, scale: Fraction) -> Self::Px

Converts this value from its current unit into device pixels (Px) using the provided scale factor.

fn from_px(px: Self::Px, scale: Fraction) -> Self

Converts from pixels into this type, using the provided scale factor.

fn into_upx(self, scale: Fraction) -> Self::UPx

Converts this value from its current unit into device pixels (UPx) using the provided scale factor.

fn from_upx(px: Self::UPx, scale: Fraction) -> Self

Converts from unsigned pixels into this type, using the provided scale factor.

fn into_lp(self, scale: Fraction) -> Self::Lp

Converts this value from its current unit into device independent pixels (Lp) using the provided scale factor.

fn from_lp(lp: Self::Lp, scale: Fraction) -> Self

Converts from Lp into this type, using the provided scale factor.
