Struct LocalToWindow 

pub struct LocalToWindow { /* private fields */ }

A positive uniform scale followed by a translation in physical pixels.

Implementations

impl LocalToWindow

pub const IDENTITY: Self

The identity coordinate transformation.

pub fn new(scale: f32, translation: PxPosition) -> Option<Self>

Creates a finite, invertible uniform coordinate transformation.

pub const fn scale(self) -> f32

Returns the uniform scale.

pub const fn translation(self) -> PxPosition

Returns the mapped local origin.

pub fn map_point(self, point: PxPosition) -> PxPosition

Maps a local point into window coordinates.

pub fn map_vector(self, vector: PxPosition) -> PxPosition

Maps a local displacement into window coordinates.

pub fn inverse_point(self, point: PxPosition) -> PxPosition

Maps a window point into local coordinates.

pub fn inverse_vector(self, vector: PxPosition) -> PxPosition

Maps a window displacement into local coordinates.

pub fn compose(self, child: Self) -> Option<Self>

Composes a child transformation followed by this transformation.

pub fn with_local_origin(self, origin: PxPosition) -> Self

Moves the local origin without changing the scale.

pub fn map_size(self, size: PxSize) -> [f32; 2]

Maps an integer layout size into fractional window extents.

pub fn map_rect(self, rect: FloatRect) -> FloatRect

Maps a local rectangle into window coordinates.

pub fn inverse_rect(self, rect: FloatRect) -> FloatRect

Maps a window rectangle into local coordinates.
