Struct epaint::tessellator::Path

pub struct Path(Vec<PathPoint>);

A connected line (without thickness or gaps) which can be tessellated to either to a stroke (with thickness) or a filled convex area. Used as a scratch-pad during tessellation.

Tuple Fields

0: Vec<PathPoint>

Implementations

impl Path

pub fn clear(&mut self)

pub fn reserve(&mut self, additional: usize)

pub fn add_point(&mut self, pos: Pos2, normal: Vec2)

pub fn add_circle(&mut self, center: Pos2, radius: f32)

pub fn add_line_segment(&mut self, points: [Pos2; 2])

pub fn add_open_points(&mut self, points: &[Pos2])

pub fn add_line_loop(&mut self, points: &[Pos2])

pub fn stroke_open( &mut self, feathering: f32, stroke: &PathStroke, out: &mut Mesh, )

Open-ended.

pub fn stroke_closed( &mut self, feathering: f32, stroke: &PathStroke, out: &mut Mesh, )

A closed path (returning to the first point).

pub fn stroke( &mut self, feathering: f32, path_type: PathType, stroke: &PathStroke, out: &mut Mesh, )

pub fn fill( &mut self, feathering: f32, color: Color32, stroke: &PathStroke, out: &mut Mesh, )

The path is taken to be closed (i.e. returning to the start again).

Calling this may reverse the vertices in the path if they are wrong winding order.

The preferred winding order is clockwise.

The stroke colors is used for color-correct feathering.

pub fn fill_with_uv( &mut self, feathering: f32, color: Color32, texture_id: TextureId, uv_from_pos: impl Fn(Pos2) -> Pos2, out: &mut Mesh, )

Like Self::fill but with texturing.

The uv_from_pos is called for each vertex position.

Trait Implementations

impl Clone for Path

fn clone(&self) -> Path

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Path

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

Formats the value using the given formatter.

impl Default for Path

fn default() -> Path

Returns the “default value” for a type.
