Required Methods§

source

fn from_points(points: &[Coord]) -> Self
where Self: Sized,

create this shape from a list of points (corners of a shape or tips of a line)

source

fn rebuild(&self, points: &[Coord]) -> Self
where Self: Sized,

source

fn contains(&self, point: Coord) -> bool

Returns true if the shape contains point

source

fn points(&self) -> Vec<Coord>

Points(corners/ends) the shape is made of

source

fn center(&self) -> Coord

Center of shape

source

fn outline_pixels(&self) -> Vec<Coord>

The coords for drawing the shape outline, the points may be in any order This should be cached rather than called per frame

source

fn filled_pixels(&self) -> Vec<Coord>

The coords for drawing the filled shape, the points may be in any order This should be cached rather than called per frame

source

fn to_shape_box(&self) -> ShapeBox

Provided Methods§

source

fn translate_by(&self, delta: Coord) -> Self
where Self: Sized,

change every point by +delta

source

fn move_to(&self, point: Coord) -> Self
where Self: Sized,

moves the shapes first point to point (and changes every other point to match their original distance and angle)

As this moves self.points()[0] the result might be unexpected if the shape was created right to left and/or bottom to top

source

fn move_center_to(&self, point: Coord) -> Self
where Self: Sized,

Moves the shapes center to point (and changes every other point to match their original distance and angle)

As this moves relative to self.points()[0] the result might be unexpected if the shape was created right to left and/or bottom to top

source

fn rotate(&self, degrees: isize) -> Self
where Self: Sized,

Rotate shape around it’s center

source

fn rotate_around(&self, degrees: isize, point: Coord) -> Self
where Self: Sized,

Rotate shape around a point

source

fn left(&self) -> isize

x of the left most point

source

fn right(&self) -> isize

x of the right most point

source

fn top(&self) -> isize

y of the top most point

source

fn bottom(&self) -> isize

y of the bottom most point

source

fn top_left(&self) -> Coord

source

fn top_right(&self) -> Coord

source

fn bottom_left(&self) -> Coord

source

fn bottom_right(&self) -> Coord

source

fn scale(&self, factor: f32) -> Self
where Self: Sized,

Scale the shape by factor (around the center, so the change will be uniform)

source

fn scale_around(&self, factor: f32, point: Coord) -> Self
where Self: Sized,

Scale the shape by factor around point
