Methods

impl Transform

[−]

pub fn from_ui_matrix(ui_matrix: &uiDrawMatrix) -> Transform

[−]

Create a Transform from an existing raw uiDrawMatrix.

pub fn identity() -> Transform

[−]

Create a new Transform that does nothing.

pub fn translate(&mut self, x: f64, y: f64)

[−]

Modify this Transform to translate by the given amounts.

pub fn scale(&mut self, x_center: f64, y_center: f64, x: f64, y: f64)

[−]

Modify this Transform to scale by the given amounts from the given center.

pub fn rotate(&mut self, x: f64, y: f64, angle: f64)

[−]

Modify this Transform to rotate around the given center by the given angle.

pub fn skew(&mut self, x: f64, y: f64, xamount: f64, yamount: f64)

[−]

Modify this Transform to skew from the given point by the given amount.

pub fn compose(&mut self, src: &Transform)

[−]

Compose this Transform with another, creating a Transform which represents both operations.

pub fn invertible(&self) -> bool

[−]

Returns true if inverting this Transform is possible.

pub fn invert(&mut self) -> bool

[−]

Attempts to invert the Transform, returning true if it succeeded and false if it failed.

pub fn transform_point(&self, point: (f64, f64)) -> (f64, f64)

pub fn transform_size(&self, size: (f64, f64)) -> (f64, f64)

pub fn ptr(&self) -> *mut uiDrawMatrix
