Implementations

impl Transform

pub fn new(a: f64, b: f64, c: f64, d: f64, e: f64, f: f64) -> Self

Constructs a new transform.

pub fn new_translate(x: f64, y: f64) -> Self

Constructs a new translate transform.

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

Constructs a new scale transform.

pub fn new_rotate(angle: f64) -> Self

Constructs a new rotate transform.

pub fn from_bbox(bbox: Rect) -> Self

Converts Rect into bbox Transform.

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

Translates the current transform.

pub fn scale(&mut self, sx: f64, sy: f64)

Scales the current transform.

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

Rotates the current transform.

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

Rotates the current transform at the specified position.

pub fn append(&mut self, other: &Transform)

Appends transform to the current transform.

pub fn prepend(&mut self, other: &Transform)

Prepends transform to the current transform.

pub fn is_default(&self) -> bool

Returns true if the transform is default, aka (1 0 0 1 0 0).

pub fn get_translate(&self) -> (f64, f64)

Returns transform’s translate part.

pub fn get_scale(&self) -> (f64, f64)

Returns transform’s scale part.

pub fn apply(&self, x: f64, y: f64) -> (f64, f64)

Applies transform to selected coordinates.

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

Applies transform to selected coordinates.

Trait Implementations

impl Clone for Transform

fn clone(&self) -> Transform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Transform

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

Formats the value using the given formatter.

impl Default for Transform

fn default() -> Transform

Returns the “default value” for a type.

impl From<Transform> for Transform

fn from(ts: Transform) -> Self

Converts to this type from the input type.

impl FuzzyEq<Transform> for Transform

fn fuzzy_eq(&self, other: &Self) -> bool

Returns true if values are approximately equal.

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

Returns true if values are not approximately equal.

impl PartialEq<Transform> for Transform

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for Transform

impl StructuralPartialEq for Transform
