impl Point

source

source

pub unsafe fn from_glib_ptr_borrow<'a>(ptr: *const graphene_point_t) -> &'a Self

impl Point

source

pub fn distance(&self, b: &Point) -> (f32, f32, f32)

Computes the distance between self and b.

§b

a Point

§Returns

the distance between the two points

§d_x

distance component on the X axis

§d_y

distance component on the Y axis

source

pub fn interpolate(&self, b: &Point, factor: f64) -> Point

Linearly interpolates the coordinates of self and b using the given factor.

§b

a Point

§factor

the linear interpolation factor

§Returns
§res

return location for the interpolated point

source

pub fn near(&self, b: &Point, epsilon: f32) -> bool

Checks whether the two points self and b are within the threshold of epsilon.

§b

a Point

§epsilon

threshold between the two points

§Returns

true if the distance is within epsilon

source

pub fn to_vec2(&self) -> Vec2

Stores the coordinates of the given Point into a Vec2.

§Returns
§v

return location for the vertex

source

pub fn zero() -> Point

Returns a point fixed at (0, 0).

§Returns

a fixed point

source§

impl Point

source

pub fn new(x: f32, y: f32) -> Self

Initializes self to the given x and y coordinates.

It’s safe to call this function multiple times.

§x

the X coordinate

§y

the Y coordinate

§Returns

the initialized point

source

pub fn from_vec2(src: &Vec2) -> Point

Initializes self with the coordinates inside the given Vec2.

§src

a Vec2

§Returns

the initialized point

source

pub fn x(&self) -> f32

source

pub fn set_x(&mut self, x: f32)

source

pub fn y(&self) -> f32

source

pub fn set_y(&mut self, y: f32)
