Implementations

impl Transform

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

Constructs a new transform.

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

Constructs a new translate transform.

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

Constructs a new scale transform.

pub fn new_rotate(angle: f64) -> Transform

Constructs a new rotate transform.

pub fn new_rotate_at(angle: f64, x: f64, y: f64) -> Transform

Constructs a new rotate transform at the specified position.

pub fn new_skew_x(angle: f64) -> Transform

Constructs a new skew transform along then X axis.

pub fn new_skew_y(angle: f64) -> Transform

Constructs a new skew transform along then Y axis.

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 skew_x(&mut self, angle: f64)

Skews the current transform along the X axis.

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

Skews the current transform along the Y axis.

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 is_translate(&self) -> bool

Returns true if the transform contains only translate part, aka (1 0 0 1 x y).

pub fn is_scale(&self) -> bool

Returns true if the transform contains only scale part, aka (sx 0 0 sy 0 0).

pub fn has_translate(&self) -> bool

Returns true if the transform contains translate part.

pub fn has_scale(&self) -> bool

Returns true if the transform contains scale part.

pub fn has_proportional_scale(&self) -> bool

Returns true if the transform scale is proportional.

The proportional scale is when <sx> equal to <sy>.

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 get_skew(&self) -> (f64, f64)

Returns transform’s skew part.

pub fn get_rotate(&self) -> f64

Returns transform’s rotate 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.
