Implementations

impl CGAffineTransform

pub const IDENTITY: Self

The identity transform — no scale, rotation, or translation.

pub const fn new(a: f64, b: f64, c: f64, d: f64, tx: f64, ty: f64) -> Self

Raw constructor; component values match Apple’s CGAffineTransformMake(a, b, c, d, tx, ty).

pub fn translation(tx: f64, ty: f64) -> Self

Translation-only transform — wraps CGAffineTransformMakeTranslation.

pub fn scale(sx: f64, sy: f64) -> Self

Scale-only transform — wraps CGAffineTransformMakeScale.

pub fn rotation(radians: f64) -> Self

Rotation-only transform (radians) — wraps CGAffineTransformMakeRotation.

pub fn concat(self, other: Self) -> Self

self then other (Apple’s matrix-multiply order). Wraps CGAffineTransformConcat.

pub fn invert(self) -> Self

Inverse transform. Wraps CGAffineTransformInvert. Returns the identity if self is non-invertible.

pub fn is_identity(self) -> bool

True if this is the identity transform. Wraps CGAffineTransformIsIdentity.

Trait Implementations

impl Clone for CGAffineTransform

fn clone(&self) -> CGAffineTransform

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CGAffineTransform

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CGAffineTransform

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for CGAffineTransform

fn eq(&self, other: &CGAffineTransform) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for CGAffineTransform
